Plastic Bottle Deposit Return Scheme Could Save England’s Councils £35m a Year

Councils across England could save up to £35m every year if the government introduces a deposit return scheme [DRS] for plastic bottles and other drinks containers, according to a new report.

Earlier this month environment secretary Michael Gove told the Conservative party conference that he would work with the industry to see how the scheme might be implemented in England.

Campaigners say it would reduce litter and help tackle plastic pollution which experts say risks “near permanent contamination of the natural environment” with potentially devastating consequences.

However, some cash-strapped local authorities have expressed concern that they would lose money as people would use the scheme rather than recycle through local authorities’ kerbside systems.

But Wednesday’s report, based on an analysis of data across eight local authorities including some with high and low recycling rates, found that rather than losing income individual authorities could make savings of between £60,000 and £500,000 each, due to reduced littering and landfill charges as well as there being fewer recycling bins to process.

Allison Ogden-Newton, chief executive of Keep Britain Tidy, one of the groups behind the report, said: “There is no doubt that introducing a deposit refund system would reduce littering in this country but, until now, there has been a concern that it would have a negative impact on cash-strapped councils. This report shows that in fact a DRS would create savings for local government.”

Over eight million tonnes of plastic enter the oceans every year, with 80 per cent coming from land. Plastic bottles are a major contributor; in June the Guardian revealed that a million are made every minute and the rate is rising quickly, with annual consumption forecast to top half a trillion by 2021.

At least a dozen nations already have a DRS, in which a small deposit is paid when purchasing the bottle, which is then returned when the empty bottle is brought back.

In Germany and Denmark, which have DRS schemes, more than 90 per cent of bottles are returned. In England, just 57 per cent of plastic bottles are recycled, mostly through streetside collection schemes.

Gove was pressured this summer by opposition parties and NGOs to introduce a DRS in England, and Nicola Sturgeon announced in September that Scotland would introduce a DRS.

In response he announced a four-week call for views to inform how the scheme would be designed. The government’s working group on the issue will also consider DRS for metal and glass containers.

Today’s report was commissioned by Keep Britain Tidy, the Marine Conservation Society, Surfers Against Sewage, Campaign to Protect Rural England and Reloop. It was carried out by environmental research group Eunomia.

It found that local authorities would lose some income as there would be a reduced number of cans and plastic bottles in the kerbside collections to sell to recyclers. However, the savings made from having fewer containers to collect and sort, as well as reduced levels of littering and reduced landfill charges would outweigh the loss of revenue.

Samantha Harding, from the Campaign to Protect Rural England, said: “There are no longer any valid arguments that DRS doesn’t work and the environmental case is crystal clear. For our coasts and countryside, the cost of not taking action will be far greater than any incurred by the parts of industry that are trying to block this. Michael Gove can now build on the success of the government’s bag charge and the ban on microbeads by confirming England will have a deposit system.”

Hugo Tagholm, from Surfers Against Sewage, said: “Deposit refund schemes are a tried-and-tested way of dramatically increasing recycling rates while reducing plastic bottle and other container pollution on our beaches, in our streets and across the countryside.

“This report now clearly shows that introducing a DRS for England would also benefit local economies and communities, saving councils money that could be redirected to vital frontline services.”

Copenhagen Mayor Wants to Phase Out Diesel Cars: ‘It’s Not a Human Right to Pollute the Air for Others’

Copenhagen’s mayor proposed a ban on new diesel cars entering the city’s environmental zone, a low-emission area that basically covers the whole of the capital, as early as 2019.

“It’s not a human right to pollute the air for others,” Lord Mayor of Copenhagen Frank Jensen told Danish newspaper Politiken (via The Local DK’s translation). “That’s why diesel cars must be phased out.”

The mayor noted that the potential ban is “controversial” but felt it was necessary to improve the city’s air quality.

About 80 people, primarily older or frail, die prematurely in the Danish capital each year due to local air pollution, including nitrous oxides from traffic, according to the newspaper.

“I know it will mean something for the many, many Copenhageners that are affected by respiratory illnesses,” Jensen explained.

The mayor’s plan applies to all diesel cars registered after Jan. 1 2019. Those who already own diesel cars would still be permitted to drive in the city.

Jensen’s remarks comes as an increasing number of countries announced proposals to ban the traditional internal combustion engine, including China, the UK, Norway, Germany, India and France.

Car ownership is declining in the famously bike-friendly city. Last November, bicycles actually outnumbered cars for the first time, when 265,700 bicycles entered the city center in a 24-hour period compared to 252,600 cars.

Copenhagen is successfully moving along its ambitious goal of becoming carbon neutral by 2025, CBS This Morning reported on Monday. That means the capital wants to produce as much clean energy as it consumes.

Last December, the mayor announced plans to shed coal, oil and gas from the city’s 6.9bn kroner ($1.1 billion) investment fund.

Open Ocean Presents Considerable Opportunity For Offshore Wind Energy Generation

New research from the Carnegie Institution for Science has highlighted the “considerable opportunity” of developing offshore wind in the open ocean, which could generate up to three to five times as much energy as wind farms on land.

Carnegie Institution for Science researchers Anna Possner and Ken Caldeira set out to determine the potential for offshore wind energy on the open ocean and found that in one scenario, open ocean-based offshore wind farms could generate at least three times more power than large wind farms on land.

To be clear, the new research, which was published in the journal Proceedings of the National Academy of Sciences, is not referring to traditional offshore wind farms — which, in theory, may soon be called near-shore wind farms. Rather, Possner and Caldeira set out to investigate the potential of open ocean, deep water wind farms — focusing primarily on the North Atlantic Ocean.

The research set out to determine the answer to a specific question; quoting from the study itself;

“Wind speeds over open ocean areas are often higher than those in the windiest areas over land, which has motivated a quest to develop technologies that could harvest wind energy in deep water environments. However, it remains unclear whether these open ocean wind speeds are higher because of lack of surface drag or whether a greater downward transport of kinetic energy may be sustained in open ocean environments.”

“Are the winds so fast just because there is nothing out there to slow them down?” Caldeira asked. “Will sticking giant wind farms out there just slow down the winds so much that it is no better than over land?”

According to the research, the majority of energy captured by large wind farms originates high up in the atmosphere and is transported downwards to the surface where the turbines are able to generate the energy from the strong winds. The authors point to other research which has concluded that the maximum rate of electricity generation for land-based wind farms is limited by the rate at which the energy is moved down towards the ground from high up in the atmosphere.

“The real question is can the atmosphere over the ocean move more energy downward than the atmosphere over land is able to?” Caldeira said.

By focusing on the North Atlantic, Possner and Caldeira found that the drag introduced by wind turbines would not slow winds down as much as they do on land, due largely to the tremendous amounts of heat pouring out of the North Atlantic Ocean into the upper atmosphere — especially during the winter.

“We found that giant ocean-based wind farms are able to tap into the energy of the winds throughout much of the atmosphere, whereas wind farms onshore remain constrained by the near-surface wind resources,” Possner explained.

Interestingly, their research found that the tremendous amount of energy generated in their models was incredibly seasonal. The North Atlantic winds produce tremendous amounts of energy in winter — enough to meet all of civilization’s energy needs, in fact — but that in summer they barely produce enough to cover Europe’s electricity demand, or the United States’.

Commercializing such deep water offshore wind technology is in its relative infancy — the most obvious idea being floating offshore wind farms, which don’t need to be built onto the seafloor. One example is the Hywind Scotland pilot park, a floating offshore wind farm being built 25 kilometers off the coast of Peterhead in Aberdeenshire, Scotland. Siemens Gamesa completed the installation of the five 6 MW floating wind turbines which were then towed from Norway to Scotland.

NREL Study Helps Plan EV Charging Infrastructure Needs

There is an old expression that says, “Never start vast projects with half vast ideas.” Converting America to electric cars will be one such vast project, one that will require a quantum leap in EV charging infrastructure, but how many chargers will be needed? How many should be Level 2 and how many should by DC fast chargers? Where should they be installed?

Answering those questions accurately will be essential to avoid wasting precious dollars on charging equipment that is the wrong type or located in the wrong places.

The National Renewable Energy Laboratory, part of the US Energy Department, has studied the problem and released a new report that attempts to answer exactly those sorts of questions. In general, its research shows that the correct answer in almost all cases is, “It depends.”

On what? Well, it depends on how many plug-in hybrids are on the road, what roads they are on and what their average range is. The same questions pertain to battery electric cars. The proportion of plug-ins to battery electrics also greatly influences the results.

By definition, plug-in hybrids have smaller batteries than battery electric cars. That means they become depleted more quickly but take less time to recharge. And of course plug-ins all have some sort of onboard range-extending engine, so running out of battery power is not as critical as it is to people who drive fully electric cars.

“The potential number, capacity, and location of charging stations needed to enable broad PEV [defined by the NREL as an vehicle with a plug] adoption over the coming decades hinge on a variety of variables,” said Eric Wood, lead author of the National Plug-In Electric Vehicle Infrastructure Analysis. “NREL’s analysis shows what effective co-evolution of the PEV fleet and charging infrastructure might look like under a range of scenarios.”

The researchers looked at the need for charging infrastructure along interstate highways and other major transportation routes. They also examined the differing needs of rural versus urban drivers. They conclude that a few hundred DC fast charging stations along major highways would satisfy the anticipated need, but when it comes to cities and rural areas, calculating the need becomes much more complex.

About 8,000 DC fast charging stations would be needed to provide a minimum level of urban and rural coverage nationwide. The need for Level 2 chargers is quite different, however. Assuming 15 million cars with plugs on the road, it could vary from a low of 100,000 to more than 1.2 million.

Why such a wide range? It all depends on whether drivers prefer long-range or short-range vehicles and the proportion of plug-in cars versus fully electric cars.

“This study shows how important it is to understand consumer preferences and driving behaviors when planning charging networks,” said Chris Gearhart, director of NREL’s Transportation and Hydrogen Systems Center.

What the study does not do is measure the impact of Tesla’s Supercharger network. Tesla is the only car company that has fully committed to building high-power and medium-power charging equipment for the owners of its electric cars. While others are thinking, planning, studying, and consulting, Tesla is doing. The unanswered question is whether that system will one day be available to non-Tesla EV drivers and, if so, on what terms?

China Holds On to Renewables Market Top Spot

Photo-illustration: Pixabay
Photo-illustration: Pixabay

China remains the most attractive market for renewables ahead of both India and the US, while the Middle East and North Africa are becoming increasingly important regions for clean energy activity, according to the latest global analysis from accounting services giant EY.

EY’s Renewable Energy Attractiveness Index was released yesterday, confirming China held on to the top position in the rankings having overtaken the US earlier this year thanks to its strong performance in the solar power and wind energy sectors.

In the wake of cancelling a number of coal power plant projects over the past year, China is aiming to spend at least $174bn on wind and hydro power over the next five years. The plans are part of a sweeping low carbon infrastructure strategy that has also seen the government work on proposals to ban new fossil fuel car sales in the country.

China has increasingly risen to prominence as a world leader on decarbonisation and clean energy, with the government actively working to cement its position as a clean energy hub following President Donald Trump’s decision to withdraw the US from the Paris Agreement.

As such, the US now lags behind China in third place in the EY rankings, with the consultancy noting that Trump’s rollback of Obama-era climate policies and trade rulings that could impact solar panel imports have dented the attractiveness of the market to global renewables investors.

However, EY notes that India’s second-spot in the list of 40 countries also “looks increasingly precarious” following cancelled wind energy power purchase agreements and steep falls in tariff bids in recent auctions, which it believes puts into doubt over the country’s 2022 target of having 100GW of solar PV installed.

Meanwhile, the election earlier in the summer of French President Macron – who has been vocal in his support for decarbonisation, renewables and the Paris Agreement – has helped push France two places higher to sixth position.

Chief editor of the Index Ben Warren, EY’s global power & utilities corporate finance leader, said the latest ranking showed government policy was pivotal in driving renewable energy development around the world.

“As it becomes increasingly clear that time is running out for legacy energy supply models, countries are vying for their place in a clean energy future,” he said in a statement. “Collaboration with existing suppliers and innovative partners through partnerships and acquisitions holds the key to success in this new world.”

Further down the rankings the UK maintains 10th spot, although the EY report highlights the success of the recent contracts for difference auction, which awarded over 3GW of offshore wind capacity at the historically low price of £57.50.

Other markets rounding out the top 10 for renewables investment attractiveness include Germany, Australia, Japan, Chile, and Mexico.

The biggest climbers in the rankings were countries in the Middle East and North Africa, where a surge in renewables activity and policy developments, financing deals and tenders have allo helped pull in investors.

In particular, the accounting firm highlights the International Finance Corporation’s approval of $635m funding in July for 500MW of solar projects in Egypt and Saudi Arabia’s invitation of bids for its first utility-scale 400MW wind farm project.

Warren said that with the right policy support, further cost reductions for renewables could be expected in the coming years, highlighting BNEF estimates that new wind and solar projects could account for 48 per cent of installed capacity by 2040, and 34 per cent of global electricity generation.

“While predictions should be met with caution in this changing landscape, the trend toward further technology cost reduction will likely drive enormous investment and faster penetration of renewables,” said Warren. “The onward march of renewable energy is also likely to generate employment, tax revenue and attractive returns for astute investors.”

SAŠA CVETOJEVIĆ: Tesla is Much More than a Car, It’s a Technology on Wheels

With a successful Croatian entrepreneur, Saša Cvetojević we talked about Tesla, the most popular electric car in the world, his last year’s travel through Europe with Tesla, this year’s participation in the EV Trophy and also about the difference between the vehicles with classical and electric drive.

Saša Cvetojević established his first company Insako for transport and logistics, which he is still successfully leading, when he was 18. He is one of the younger Croatian millionaires and he often invests money in good ideas and companies. He graduated from Faculty of Economics in Zagreb, and after that he finished postgraduate studies in healthcare management at Medical School.

He belongs to the most influential people in Croatia who constantly points out the things that should be better in the country through media and social networks. An extensive book could be written about his successes and examples of good practice and we asked him to share with us part of his experience in terms of electric cars.

EP: Given the fact that three years ago, you were the first owner of Tesla in Croatia, can you tell us why did you pick precisely this car?

Saša Cvetojević: I chose Tesla because it was more than the car itself. It is still valid today. Tesla is a sort of “statement” of the time that is coming. It’s a technology on wheels. The fact that it is an electric car is just the beginning of the story but definitely not the end of it. Electric cars, apart from being far more efficient in use, significantly less pollute the surroundings and enable complete change in the concept of utilization and use of cars. They influence the creation of entirely new eco system.

EP: How developed was the charging network in Croatia at the time you bought the car and is it better now?

Saša Cvetojević: When I bought the first Tesla there were just a few chargers, a little bit more than you have now in Serbia. However, one should bear in mind that every socket is a charger for an electric car. It’s just the matter of charging speed, but there is also a lot of prejudice in this regard. Today in Croatia we have three Tesla’s superchargers, one is about to be opened and the other two are under construction. In addition to that, we have twentyish Tesla’s Destination Chargers and around 200 of other chargers of various power. There are no fast chargers on the highways that would enable other electric cars to cross longer distances. Slovenia is a good example there, since there are fast chargers on most of the gas stations on highways.

EP: Is eco-mobility still a privilege of the rich?

Saša Cvetojević: No, it’s not. I know a lot of people who converted their cars into electric ones, from fiat, to even beetle or trabant. Now they drive them around the city or on shorter intercity routes and it is very profitable. Tesla is a high-class car, but the arrival of new models in the middle class is becoming more than apparent. In two to three years, I expect huge changes in middle and lower price class of electric vehicles. Assuming that the price of batteries will drop at a pace that is already noticeable, as well as the development of the fast charging network in the next few years an electric car should even be cheaper than a comparable car on “classical” drive.

EP: Does it make sense to drive an electric car in Croatia given the fact that almost 50 per cent of energy comes from thermal and nuclear power plants? 

Saša Cvetojević: Of course, it makes sense. Even if 100 per cent of energy comes from thermal power plant, the consumption efficiency of electric motor, with the use of electricity in “off peak” periods in which the grid anyway has the surplus of electricity, is a good solution both ecologically and financially. Still, we should look a little bit into the future. Renewable sources have a growing share in the production, and the Tesla itself guarantees that the entire electricity they deliver to their superchargers is exclusively bought from those that produce energy from renewable sources.

EP: Can you as a successful and public figure influence the attitude of ordinary people?

Saša Cvetojević: Of course, and I see that every day. People are writing, asking… They are changing some of their habits if they have someone who can testify and share experience from their personal example. Since I do not have any business agreement with Tesla, I have never received a cent from them and that there is no chance that will happen in the future, I do believe that everything I write and do is fully credible. Simply, I believe that electric cars are the future and we who have more money and certain impact should show this by setting an example and not just words. For example, we who are the first users, have paid those cars much more than they will cost later. We paid and we are paying the development costs from which later, with an expansion of the number of manufacturers and models and the economics of scale, will arrive cheaper and more available models.

EP: Last year, you went on a journey through Europe with your Tesla S and you crossed around 10,000 km. Did you have any difficulties while traveling? Did you have any problems when charging your car apart from Serbia?

To find out more about Sasa Cvetojevic’s cruising throughout Europe in his Tesla check the interview he gave us for the new issue of our bulletin on Ecomobility which was released this July.

Micosoft Inks 15-Year Deal to Buy Power from GE’s Irish Battery Wind Farm

Microsoft has inked a 15-year deal to use 100 per cent of the power generated by GE’s 37MW Tullehennel onshore wind farm in Ireland, in order to support growing demand for the software giant’s cloud services.

Building on the strategic partnership between Microsoft and General Electric (GE) announced last year, the two firm’s yesterday said they had signed a power purchase agreement (PPA) for the County Kerry wind farm project.

In addition to producing energy, each of the wind farm’s turbines is to have an integrated battery installed, enabling Microsoft and GE to test how these batteries can be used to capture and store excess energy, and then provide it back to the grid as needed.

The two companies said the project would help to encourage wider uptake of intermittent renewable power sources on the grid and would be “the first deployment of battery integration into wind turbines to store energy in Europe”.

Christian Belady, general manager of Microsoft’s datacenter strategy, said the project would help make it easier to incorporate renewables onto Ireland’s grid. “Our commitment will help bring new, clean energy to the Irish grid, and contains innovative elements that have the potential to grow the capacity, reliability and capability of the grid,” he explained.

Once operational, the new wind project will bring Microsoft’s total global direct procurement in renewable energy projects to almost 600 megawatts, the company said.

Microsoft has also agreed a separate deal with Dublin-based company ElectroRoute to provide energy trading services to the firm in Ireland, and is additionally seeking to acquire an Irish energy supply license from GE to give the software giant “flexibility to easily grow and invest in renewable energy in Ireland over time”.

GE said its Tullehennel wind farm would also integrate its digital wind farm technology and Predix digital data analysis platform to ensure supplied energy generation can meet forecasted demand and reduce intermittency concerns.

Andres Isaza, chief commercial officer of GE Renewable Energy, said the partnership with Microsoft would help expand GE’s business in Ireland, where it employs 1,500 people.

“Wind is now one of the most competitive sources of electricity on the market today, and we’re excited about the capability to use data generated from these wind turbines, using the Predix platform, to maximize the output and value of this project,” he said.

Rooftop Solar Provides 48% of South Australia Power, Pushing Grid Demand to Record Low

Foto-ilustracija: Pixabay
Photo-illustration: Pixabay

South Australia’s level of minimum demand hit a new record low this weekend – barely a week after the previous benchmark was set – with a fall to just 587 MW last month.

The record eclipsed the previous mark by nearly 200MW – with AEMO data showing minimum demand at 1.30pm of exactly 587.8MW, compared with the previous low mark of 786.42 MW posted last month.

The key here appears to be the moderate temperatures of early spring, which meant few air conditioners switched on, combined with excellent solar output, with the state’s more than 700MW of rooftop solar producing 538.54 MW at the time of minimum demand.

That is a phenomenal share of 47.8% of the state’s electricity demand being met by rooftop solar (compares with 36% in the previous record last week) and is clearly a record for South Australia, and for that matter in any large grid anywhere in the world.

As we reported last week, the tumbling records confirm that the times of record low demand have shifted from the night to the middle of the day.

The Australian Energy Market Operator has predicted that by 2019, record low demand may fall to just 354 MW, and within 10 years the grid demand may fall to zero because of the increasing amount of rooftop solar. This is also likely to occur in Western Australia around the same time.

South Australia is the first region where rooftop solar PV has caused a shift in minimum demand from night time to the middle of the day (most states still have electric hot water being switched on at night, when it would make sense to use the “solar sponge” as Queensland has suggested).

The impact of rooftop solar is being felt in prices – look at the black line that shows prices fall as rooftop solar accounts for a sizeable share of demand during the day.

Note, also, the negative price of minus $44/MWh at 6am when there was abundant wind and a constraint on the connector with Victoria.

South Australia is the first region where rooftop solar PV has caused a shift in minimum demand from night time to the middle of the day (most states still have electric hot water being switched on at night, when it would make sense to use the “solar sponge” as Queensland has suggested).

“It’s absurd to continue having hot water heating at this hour,” says Dylan McConnell, from Melbourne’s Climate and Energy College.

“It’s completely contradictory to the original intention of having water heating at this hour: to use ‘off-peak’ electricity. In many cases, this is actually the peak – and off-peak has shifted to the middle of the day.”

AEMO chief Audrey Zibelman has welcomed this change in technologies and load curves as “not a bad thing”, but they do have to be managed differently.

It also questions the need for old-fashioned concepts such as “baseload”, which would struggle to find a niche in a market dominated by wind and solar, where mostly “dispatchable” and flexible generation is needed to fill in the gaps. Wind energy is already producing more than 100% of local demand at certain times.

As we note in our updated story about prime minister Malcolm Turnbull’s rooftop solar and battery storage system in his Point Piper mansion, AEMO predicts that around 40% of Australia’s supply could come from “distributed generation”, which effectively means rooftop solar and storage.

That sort of solar and storage is likely to be more useful to the grid operator than oldcoal-firedd power stations.

And new analysis from Bruce Mountain at Carbon and Energy Markets suggests exactly that: rooftop solar and battery storage systems would be better suited for AEMO to manage the changing grid than spending vast amounts of money in extending the life of ageing, unreliable and increasingly expensive coal generators such as Liddell.

Enel Green Power North America announced last week that it has signed a $330 million tax equity agreement with the Alternative Energy Investing Group of Goldman Sachs and GE Energy Financial Services to spur development of Oklahoma’s 298 MW Thunder Ranch wind project.

The announcement was made on Friday in which Enel Green Power North America revealed that Alternative Energy Investing Group of Goldman Sachs and GE Energy Financial Services would together purchase 100% of the 298 MW (megawatt) Thunder Ranch wind project’s Class B and Class C equity interests in exchange for payment of approximately $330 million. Enel Green Power will retain 100% of Thunder Ranch’s Class A interests and control of the project.

These tax equity investments are traditional financing methods for the development of renewable energy projects across the United States. In turn, Goldman Sachs and GE Energy Financial Services will receive a percentage of the financial benefits generated by Thunder Ranch.

Construction of the 298 MW Thunder Ranch wind project began back in May after Enel Green Power committed approximately $435 million into the project, part of the company’s larger investment plans. Upon completion, Thunder Ranch generate more than 1,100 GWh (gigawatt-hours) of clean energy each year and provide enough electricity to meet the needs of the equivalent of 89,400 US homes, and subsequently avoid CO2 emissions worth around 790,000 tonnes.

Thunder Ranch was also in the news last month as the focus of a Power Purchase Agreement (PPA) concluded by Missouri-based Anheuser-Busch, brewer of drinks such as Budweiser and Stella Artois, and one of America’s leading breweries. Anheuser-Busch announced mid-September that it would purchase 152.5 MW generated by Thunder Ranch to support its brewing operations in the United States. Further, the company can now boast 50% renewable energy purchased, and the ability to produce 20 billion 12-ounce servings of beer each year.

“As we strive to bring people together to build a better world, we at Anheuser-Busch are dedicated to reducing our carbon emissions,” said João Castro Neves, president and CEO of Anheuser-Busch at the time. “Helping to grow the renewable energy market is not only good for the environment, it is a strategic business move as we strive for long-term sustainability. Now more than ever, we are excited to lead our company’s global effort toward a renewable future and, partnering with Enel, set an industry example of how major companies can help to make a difference in climate change.”

Newly-formed Siemens Gamesa Renewable Energy has announced that it has been awarded an extension to its service agreement for the 504 megawatt Greater Gabbard Offshore Wind Farm in the UK.

Service agreements may not be the sexiest renewable energy story when you can instead point to Tesla battery storage stories and mammoth offshore wind project announcements and completions, but they are nevertheless likely to be the most impactful renewable energy stories over the long-term. Big and small project announcements and completions will certainly continue to draw the attention of many, but it is the service agreements which will keep those projects running long after the thrill of multi-megawatt announcement stories has passed.

Announced last week, Siemens Gamesa Renewable Energy — the resulting company of a merger between Spanish wind energy giant Gamesa and Siemens wind energy division — revealed that it had been awarded an extension to its service agreement for the 504 MW Greater Gabbard Offshore Wind Farm, located off the coast of Suffolk in England. The agreement has been extended by 5 years to continue operation and maintenance services through to 2022.

The extension to the Greater Gabbard service agreement is the latest of three service contract extensions recently awarded to Siemens Gamesa, in addition to two 10-year service agreement extensions for the London Array wind farm and the Lynn & Inner Dowsing wind farms. In total, Siemens Gamesa is now real-time monitoring in excess of 3,200 wind turbines across 128 onshore and offshore wind farms with a total output capacity of 9.5 gigawatts.

“We are very pleased that Siemens Gamesa has been selected again to provide service and maintenance services for the Greater Gabbard wind farm,” said Mark Albenze, CEO, Service, Siemens Gamesa Renewable Energy. “This five-year extension underscores our commitment to providing customers with value-driven service plans targeted to their specific operational needs and complemented with our advanced digital services that help drive down the costs associated with wind energy. We thank GGOWL for their continued confidence in our products and services.”

Australian Greens’ New Policy Pushes For 20GW By 2020

Foto-ilustracija: Pixabay
Photo-illustration: Pixabay

The Australian Greens have unveiled a new policy that aims for 20GW of energy storage to be installed across the nation by 2030, providing incentives for storage at household and grid level, and try to move the energy debate beyond the limited scope of baseload vs. renewables.

The policy was unveiled in South Australia on Wednesday by deputy leader and climate and energy spokesman Adam Bandt, and South Australia Senator Sarah Hanson-Young.

Their goal is to try to “supercharge” the household and business storage market, and set national milestones similar to the renewable energy target to reach their goal by 2030.

The Greens say that 20GW could translate to 400GWh of storage, enough they say – according to recent studies by the ANU – to provide sufficient back-up for a 100 per cent renewable energy grid.

To reach such storage levels, it would presumably need to include a major scheme such as Snowy 2.0 or Tassie 2.0, as well as battery storage at local and grid level, other pumped hydro storage of the type being considered for South Australia, and solar thermal.

The fact that most of these projects are having their first run in South Australia – the Tesla big battery, the AGL virtual power plant, the Aurora solar thermal project, and the Cultana pumped hydro facility – made it an appropriate place for the launch of an energy storage target.

South Australia also has the highest level of renewable energy penetration of any large modern grid, with wind providing around half of its demand, and rooftop solar another 7-8 per cent.

“To have an orderly energy transition away from coal and gas we need energy storage throughout the system,” Bandt says.

“This includes batteries in homes and businesses to reduce demand, as well as on the grid to provide frequency control. We also need small to medium scale pumped hydro to provide flexible generation to complement wind and solar.”

The political debate around energy baseload has become stuck in the argument over baseload versus variable renewables, and become bogged down by the Coalition push to have the ageing Liddell kept online and even a new coal generator built in north Queensland.

In doing so, the debate has largely and deliberately ignored the subtleties and complexities identified by the recent Finkel Review and the AEMO reports, which focus on the need for flexible and “dispatchable” generation – and which make it clear that properly managed, a high penetration renewables grid is eminently feasible.

“We don’t have a base load problem, we have a peak load problem,” Bandt says. “We need flexible generation and energy storage to manage the transition, not more coal.

A glimpse into how quickly the tradition could and might happen came the unveiling of the first stage of the Tesla big battery last week, when Tesla founder and CEO Elon Musk revealed that half of the project had already been installed. The quicker we get more renewables into the system, the better, Musk said.

Major manufacturers in Australia are also picking up on the benefits of renewables, for cost and reliability. The new owners of Whyalla Steel and the former OneSteel assets across the country plan a program to transfer their energy sources to renewables and storage, as does the country’s biggest greenhouse proposed by Nectar Farms.

Across the globe, the world’s biggest companies – Google, Amazon, Apple, Facebook and Microsoft – are heading for 100 percent renewables (most by 2020), and these are being matched by big investment banks such as JP Morgan and Citibank, and brewers and retailers like In-Bev (owner of Foster’s) and IKEA.

Australian networks also say that 100 percent renewable energy, or thereabouts, is both doable and affordable, but the country has yet to see a coherent plan to take the energy share to a high level of renewables and with the necessary infrastructure and storage to support it.

The Greens say their energy storage target is part of a suite of initiatives that include the creation of a Frequency Control and Ancillary Services Market to enable participation of energy storage in fast frequency response, and the shifting to a 5 minute settlement rule for the wholesale energy market. Many of these are already in train.

It also proposes to support and extend the various state government energy storage tenders (currently being held by South Australia, Victoria and Queensland, and on a smaller scale by the ACT and the Northern Territory) to push for the increased take-up of electric vehicles and to introduce them into the grid as a storage component.

For consumers, the policy suite would see a small-scale energy storage scheme (based on the Small-Scale Renewable Energy Scheme which applies to rooftop solar), which would be managed by the Clean Energy Regulator. Systems of up to 250KW/1MWh will be eligible.

On the grid scale, it proposes establishing a Commonwealth Large Scale Energy Storage Scheme, with $2.2 billion in funding over 4 years to contract and build energy storage at grid level, managed by AEMO and the CER.

“People are already starting to install batteries in their homes,” Bandt says. “We want to supercharge demand for batteries in households and business, saving people money and creating jobs with a program that mirrors the support for rooftop solar.”

“Snowy 2.0 is a nice idea, but if the government was serious about energy storage it would put in place a target and incentives for storage right across the electricity network, not just in one place.”

Hanson-Young says that South Australia is already leading the world in renewable energy generation and was installing grid level battery storage, but there is much more to do.

“Turnbull’s plan for more coal authored by Tony Abbott and Labor’s plan for more gas is not the solution. We need more renewables and more storage.

“A national energy target can support projects like the planned solar thermal power plant in Port Augusta that uses molten salt storage or the proposed pumped hydro using sea water in the Spencer Gulf. The investment in storage technologies here in South Australia must be supported by a national plan.”

The Greens policy outline acknowledges the critical role that energy storage can play to “decouple” supply and demand on the electricity grid, making electricity akin to a normal commodity that can be warehoused and distributed with a much greater degree of control.

This can boost the efficiency of the grid; improved utilisation of generation, increase renewable energy sources and make them flexible.

“While energy storage, particularly battery storage, will grow, there are significant barriers to the planning, penetration and the speed of investment needed to underpin a 50% or 100% renewable energy grid.

“A number of countries and other jurisdictions are putting in place or examining storage targets and other policies to support investment energy storage, including in California which, four years ago, set a 1.3 GW storage target by 2020.”

Coal Has Been Largely Banned In China’s Taiyuan (Capital Of Shanxi)

The capital city of China’s Shanxi province, Taiyuan, has now largely banned the sale, use, and transport of coal in a bid to reduce local air pollution problems, according to the country’s state news agency, Xinhua.

The word “largely” was used because the ban doesn’t affect the province’s large steel production plants or power plants — everyone else, though, is now expected to essentially do without the energy-dense fossil fuel. The ban applies to individuals as well as to companies.

The ban, according to Xinhua, is expected to slash coal consumption in the city by 90% — equating to a cut of around 2 million tonnes of use a year.

“China has ordered Beijing and nearby provinces, including Shanxi, to limit concentrations of airborne pollutants and meet key smog targets in more than two dozen cities starting this month and lasting until March. That period is when air pollution typically increases as more coal is burned to provide heat during the winter,” Reuters reports.

“Coal is the biggest source of air pollution in Taiyuan in winter, Xinhua quoted Dou Lifen, head of the city’s environmental protection bureau, as saying. The city was replacing coal-burning household heating equipment with electric and natural gas heaters, Xinhua said.”

The city is reportedly expecting that the new ban will reduce the number of days featuring “heavy air pollution” to 22 — making for a roughly 40% reduction from 2016 figures. Those are official expectations, though — we’ll of course have to wait to see how things play out in practice. The ban will no doubt help somewhat, though.

Australian Gullen Range Hybrid Solar & Wind Farm Is Now Generating Energy For The Grid

The Gullen Range solar farm – the first in Australia to be co-located with a wind farm – has begun generation into the grid.

The 10MW solar farm is adjacent to the 165MW Gullen Range wind farm, and both are owned by New Gullen Range Wind Farm, a company owned 25 per cent by Chinese renewable energy giant Goldwind and 75 per cent by Beijing Jingneng Clean Energy.

Gullen Range is one of a number of co-located wind and solar projects that are being built in order to share infrastructure such as roads, power lines and telecommunications, and so lower costs, and also because of the way their output can complement the other.

Goldwind is also building the 20MW White Rock solar farm near Glen Innes in northern NSW, next to the White Rock wind farm, while Windlab is also planning to build a 60MW project comprising both wind and solar – and battery storage – at the Kennedy project in north Queensland.

That project could expand to 1,200MW, providing what its developers describe as “baseload” renewables for the region. CWP is also planning a large solar farm with battery storage to partner the Sapphire wind farm that is also being built in northern NSW.

DP Energy is looking to a solar-wind hybrid at its Port Augusta renewable energy park in South Australia, and APA is building a solar farm at Emu Downs to co-exist with the existing wind farm of the same name.

Gullen solar first produced in late August, and has been putting into the grid on a regular basis since around mid-September. This graph above, courtesy of the Climate and Energy College in Melbourne, shows the combined output of the solar and wind farms in the past week.

The Gullen Range solar farm attracted a $10 million grant from the Australian Renewable Energy Agency, even though its projected costs – $2.6 million a megawatt – were well above the average of $2.16 million/MW from the projects that made its short-list for the recent large scale solar tender.

However, ARENA explained at the time that they were keen to see a co-located wind and solar farm, and estimated that there were 1,000MW of solar projects that could be co-located.

“Co-location provides more continuous energy generation, as wind farms tend to generate more energy overnight whilst solar only generates during the day. Gullen Wind Farm generates more power in winter and the new solar farm will generate more in summer,” ARENA boss Ivor Frischknecht said at the time.

“Wind farm owners across Australia could benefit from adding solar plants to their existing sites. Developers can save money on grid connection, approvals and site development costs by co-locating wind and solar plants, whilst also reducing environmental impacts.

Gullen Range was built by the Decmil Balance joint venture.

Note: The Gullen Range Wind Farm and Gullen Solar Farm are conducting Wind and Solar Farm Tours. The first tour will take place on Tuesday, 24th October at 11.30am.

It says the tours are a great opportunity for the community to visit Australia’s first hybrid wind and solar farm, which is located along SERREE‘s (South East Region of Renewable Energy Excellence) Renewable Energy Trail. For more information and to book a tour, click here.

Price Of Solar Panels Keeps Falling In The Netherlands

The cost of solar power has never been lower. This is reflected by installations — massive projects are under construction around the globe and a record-breaking 74 gigawatts of installations were completed in 2016. Although this growth is unequally distributed over different countries and dominated by utility-scale solar farms, the smaller-scale residential segment has contributed a fair share. The main driver of growth, continuously dropping costs, is incentivizing companies and individuals alike to go solar. Certainly, this is what has been going on in the Netherlands.

According to MilieuCentraal, a public awareness agency funded by the Dutch government, the price of buying solar panels dropped by almost 10% year on year in August 2017, continuing the downward trend of cheaper and cheaper renewable options. A standard system of 10 solar panels, including inverter and labor expenses, costs a Dutch citizen on average of €4400, or €1.63 for each Wp of capacity. This is 15 euro cents less than in 2016, when the same system would have set you back €1.78 per Wp. As a result, the return on investment for covering your roof with panels has risen to 6% annually, which is significantly above global interest rates, even though the risk involved seems to not be that much greater. Also, in this computation of returns, a VAT rebate the Dutch government offers has not been included.

The falling price of solar panels is reflected in their sales. By now, more than half a million houses are equipped with solar in the Netherlands, which is 100,000 more than one year ago. In relative terms, 11% of households with their own roof have put panels on top, making up about two-thirds of total solar capacity in the Netherlands.

In the years to come, strong growth is likely to continue. Just last week, dairy company FrieslandCampina announced it will put a total of 416,000 solar panels on the roofs of its supplying farms, reflecting the interest from all sorts of different actors in reducing the carbon footprint of their electricity supply by turning towards the sun for their energy needs.

London Considers Banning Wood-Burning Stoves to Tackle Air Pollution

Wood-burning stoves could be producing up to one third of London’s fine particle pollution, according to figures cited by the city’s mayor, Sadiq Khan. A ban on the stoves could help address the air pollution plaguing the capital; last week, Khan triggered the emergency air quality alert for the seventh time in 13 months.

Wood-burning stoves have recently been popular in Britain – The Guardian reports 1.5 million have been sold in the country. 16 percent of households in southeast England have the stoves, compared to five percent nationally. But somewhere between a quarter and a third of fine particle pollution in the capital could arise from domestic wood burning. And King’s College London research indicates during very high air pollution in January, domestic wood burning yielded half of the emissions in some parts of London.

Khan said, “Non-transport sources contribute half of the deadly emissions in London, so we need a hard-hitting plan of action to combat them similar to moves I am taking to reduce pollution from road vehicles. With more than 400 schools located in areas exceeding legal pollution levels, and significant health impacts on our most vulnerable communities, we cannot wait any longer.”

In a letter to Environment Secretary Michael Grove, Khan requested London’s environment department amend a Clean Air Act to set up zero-emission zones where people won’t be allowed to burn solid fuel from 2025 on.

Khan also called for tougher enforcement on emissions restrictions for construction machinery like diggers and bulldozers, and for greater powers to tackle emissions coming from Thames River traffic.

In a statement, the London government said half of air quality

come from cars and other road vehicles, and that the second-largest source of PM 2.5 particles is construction machinery.

Global Carbon Emissions Stood Still in 2016, Offering Climate Hope

The new data is a welcome sign of progress in the battle against global warming but many challenges remain, including methane from cattle.

Global emissions of climate-warming carbon dioxide remained static in 2016, a welcome sign that the world is making at least some progress in the battle against global warming by halting the long-term rising trend.

All of the world’s biggest emitting nations, except India, saw falling or static carbon emissions due to less coal burning and increasing renewable energy, according to data published on Thursday by the Netherlands Environmental Assessment Agency (NEAA). However other mainly developing nations, including Indonesia, still have rising rates of CO2 emissions.

Stalled global emissions still means huge amounts of CO2 are being added to the atmosphere every year – more than 35bn tonnes in 2016 – driving up global temperatures and increasing the risk of damaging, extreme weather. Furthermore, other heat-trapping greenhouse gases, mainly methane from cattle and leaks from oil and gas exploration, are still rising and went up by 1% in 2016.

“These results are a welcome indication that we are nearing the peak in global annual emissions of greenhouse gases,” said climate economist Prof Lord Nicholas Stern at the London School of Economics and president of the British Academy.

“To realise the goals of the Paris agreement and hold the increase in global average temperature to well below 2C, we must reach peak emissions as soon as possible and then achieve a rapid decline soon afterwards,” Stern said. “These results from the Dutch government show that there is a real opportunity to get on track.”

Jos Olivier, the chief researcher for the NEAA report, sounded a note of caution: “There is no guarantee that CO2 emissions will from now on be flat or descending.” He said, for example, a rise in gas prices could see more coal burning resume in the US.

The flat CO2 emissions in 2016 follow similar near-standstills in 2014 and 2015. This lack of growth is unprecedented in a time when the global economy is growing. As the number of years of flat emissions grows, scientists are more confident a peak has been reached, rather than a temporary halt. In July 2016, senior economists said China’s huge coal burning had peaked, marking a historic turning point in efforts to tame climate change.

Stern said many of the big emitting nations had achieved significant reductions in 2016: “However, all countries have to accelerate their emissions reductions if the Paris goals are to be met.” He said this could also drive development in poorer nations: “We can now see clearly that the transition to a low-carbon economy is at the heart of the story of poverty reduction and of the achievement of the UN Sustainable Development Goals.”

The new Dutch report shows CO2 emissions from China, the world’s biggest emitter, fell 0.3% in 2016. US CO2 emissions fell 2.0% and Russia’s by 2.1%, with the EU flat, although UK emissions tumbled by 6.4%, as coal burning plunged.

Of the top five emitters, only India’s CO2 emissions rose, by 4.7%. Significant increases were also seen in Indonesia, Malaysia, the Philippines, Turkey and Ukraine.

Global carbon emissions stood still in 2016 but other greenhouse gases rose slightly

Carbon dioxide and total greenhouse gas emissions, billions of tonnes of CO2 equivalent

However, over a quarter of the warming effect seen by the world comes from non-CO2 greenhouse gases, with methane by far the most significant. Cattle belch the gas and are responsible for 23% of global methane emissions, and this source rose by 0.4% in 2016. Scientists have warned that the growing global appetite for meat, especially beef, cannot continue if climate change is to be kept under 2C.

Another quarter of methane emissions come from fossil fuel production and leaks in gas distribution pipes. Since 2000, emissions from coal and gas production have grown by more than 65%.

Carbon emissions from forest destruction and other land use changes were not included in the main analysis as they are more difficult to estimate and vary strongly from year to year.
