UK Climate Minister says government will ask climate watchdog to consider how UK could meet 1.5C Paris target

Later this year the UK government will formally ask its official climate experts, the Committee on Climate Change (CCC), to explore the potential for the UK to tighten its emission reduction targets to bring them in line with international goals, Energy and Climate Minister Claire Perry announced today.

Speaking during the Commonwealth Heads of Government Meeting (CHOGM) taking place in London this week, Perry said she would instruct the CCC to report on the implications of the Paris Agreement’s target to limit a rise in global average temperature to “well below” 2C and aim for 1.5C.

“After the IPCC’s report later this year, we will be seeking the advice of the UK’s independent advisors, the Committee on Climate Change, on the implications of the Paris Agreement for the UK’s long-term emissions reduction targets,” Perry said.

Under the 2008 Climate Change Act the UK already has a target to cut greenhouse gas emissions by 80 per cent by 2050, against 1990 levels, which is technically consistent with Paris goals to limit warming to below 2C.

But there have been growing calls for the government to boost its national targets in light of the Paris Agreement’s target for reducing annual emissions to ‘net zero’ during the second half of the century, which would require anthropogenic emissions to be balanced by the removal of greenhouse gases from the atmosphere.

Campaign group Plan B is currently pursuing a legal challenge against the government in a bid to get the law strengthened, while research from the LSE’s Grantham Research Institute last month also backed a net zero goal.

In March 2016 former Energy Minister Andrea Leadsom promised the UK would enshrine a net-zero emissions goal into UK law, but following the Brexit vote and last year’s election plans stalled.

The Intergovernmental Panel on Climate Change – the IPCC – is due to release a report on the global implications of the 1.5C target in September. Perry said she would instruct the CCC to look at how the UK would meet such a goal after that report is released. The CCC will not only evaluate the UK’s current target in light of the 2015 Paris Agreement, but also latest science and technology, both of which have moved on fast in the 10 years since the Climate Change Act was first agreed.

If it does opt for a tougher goal, the UK government will have to act quickly to give the country the best chance of achieving faster decarbonisation. According to the LSE researchers, a fresh target would need to be in place by 2020 to coincide with the submission of revised ‘nationally determined contributions’ to the Paris Agreement and the CCC’s advice on the sixth carbon budget.

The UK is the first G7 country to formally promise to explore a net zero goal, and polling research suggests the move has strong public support. Conservative environmental think tank Bright Blue this week released analysis of polling from Opinium suggesting that 64 per cent of UK adults agree the UK should aim to cut its emissions to zero over the next few decades.

The survey, which questioned more than 4,000 adults, found that 51 per cent of people are more concerned about climate change today than a decade ago, climbing to 57 per cent among the under 40s.

“A net zero target is supported by a clear majority of the public, including Conservative voters, while concern about climate change is particularly high among younger voters,” Bright Blue head of research Sam Hall said. “By adopting a net zero target, the government is therefore seizing a great opportunity to appeal to key younger voters without trading off existing voters.”

Former climate diplomat and CEO of the European Climate Foundation Laurence Tubiana, today urged other nations to follow the UK’s lead.

“10 years after the UK pioneered its world-first Climate Change Act, today’s announcement shows that once again it is the British government looking to lead the world on climate change,” she said. “For a safe climate we need all governments to aim for cutting pollution to net zero levels by 2050. This decision to review Britain’s long-term climate target sends a strong message to the EU and other big economies that London is committed to the Paris Agreement, and now it’s time they too considered what more they can do.”

Reaction among other campaigners and climate experts was also almost universally positive. Ed Matthew, associate director at environmental think tank E3G, said a net zero goal would “cement the UK as the global leader in the battle against climate change”.

Former environment secretary and former leader of the Conservative Party Lord Michael Howard also welcomed the news. “The Climate Change Act has proven its worth, but as science and diplomacy move on, it should of course be kept under review – and the tougher international targets agreed at the Paris summit make it likely that the UK’s own target will need to be strengthened,” he said.

More Good News About Coal-Killing Perovskite Solar Cells

18.04.2018

US coal and nuclear energy stakeholders are still holding out hope for their aging power plants, but the window for relief is closing fast. They face stiff competition from low-cost natural gas, and renewables are flexing their muscles, too. This is all happening before perovskite solar cells hit the market at scale. Why does this matter? New perovskite technology could drive solar costs down past conventional silicon solar cells, pushing both nuclear and fossil energy farther out of the picture.

For those of you new to the topic, perovskite refers to a class of lab-grown, crystalline materials that mimic the structure of the naturally occurring mineral perovskite.

Synthetic perovskites have caused quite a stir among photovoltaic researchers in recent years. They are relatively cheap and easy to grow in the lab, and they can be used in a thin-film format that provides the additional benefits of high volume, low-cost solar cell manufacturing.

In a perfect world, perovskites would offer a low-cost alternative to conventional silicon solar cells. Unfortunately for solar energy fans, the world is not a perfect place for perovskites because they degrade quickly when exposed to humidity.

On the bright side, there is a solution. Someone just has to find it.

The EU consortium Solliance is one of many research organizations working the problem. Last November it announced a world record of 13.5% for its thin film perovskite solar cell, and just last week it updated its perovskite PV progress. The latest iteration of the cell hit the 14.5% mark.

Last week’s announcement is also significant because Solliance demonstrated that the new cell can be interconnected with others to make a larger module without a significant loss of efficiency.

The trick is to make sure that the active material covers as much of the module as possible. Solliance shrank the non-active, interconnection areas down to a fraction. It achieved 95.3% coverage for the active areas and ended up with an efficiency of 13.5% for the module overall.

Then there’s that thing about low-cost manufacturing:

…Apart from the electrodes currently used, all layers can be processed in ambient environment and at temperatures below 120⁰C, making expensive equipment obsolete. The deposition and interconnection technologies are industrially available for both Sheet-to-Sheet and Roll-to-Roll manufacturing.

As for when you can get your hands on that low-cost thin film solar cell, that’s a good question. It doesn’t look like that will take forever, though. Panasonic is a partner in the consortium along with the “disruptive” renewable energy company Greatcell Solar Limited and the Russia-based solar business incubator Solartek.

Speaking of progress, one of the world’s biggest cheerleaders for perovskite solar cells is the National Renewable Energy Laboratory, and it has just come out with an article that outlines just how quickly things are developing in the field.

Perovskites were unstable and there were all kinds of problems—but you could clearly see in all the measurements that these were high-quality semiconductors. We saw where efficiency records were broken day after day after day. We realized this is not something we should be ignoring.

The article also makes a good case for the advantages of perovskites over silicon:

…The silicon technology requires a high-temperature manufacturing process, whereas the perovskite process is simpler: chemicals are applied to a substrate, either by deposition or roll-to-roll printing. When dry, the residue leaves crystals that serve as excellent semiconductors. This means perovskite panels are more flexible than rigid silicon panels…

At this point, NREL is confident that perovskites will break into the market. Here’s a take from NREL staff scientist David Moore:

I don’t see anything that stands in the way of commercialization of perovskite. There are a couple of challenges left. We need to make sure they’re going to last 30 years. But the strides we’re making in those areas are just as rapid as the progress we made with efficiency in the first five years. Just based on the progression of both of those things, there’s every reason to believe that we’ll continue on that path to solve those problems…

The article cites a laundry list of improvements and discoveries that NREL has made in just the past year, so if you want to see your tax dollars at work hop on over and check out “NREL Research Pushes Perovskites Closer to Market” over there at NREL.gov.

Less Meat and More Green Power: Scientists Cook Up 1.5 Degrees Trajectory with Minimal Reliance on Negative Emissions

17.04.2018

cow-759018__340 — Photo-illustration: Pixabay

Scientists at Utrecht University in the Netherlands have modelled a way to hit tough global climate targets without resorting to the extensive use of negative emissions technology such as bioenergy with carbon capture and storage (BECCS).

Most 1.5 degree climate scenarios – a temperature limit that would save low-lying islands from rising sea levels and avert the worst economic and ecological impacts of climate change – rely heavily on negative emissions technology to make the numbers add up.

But such technology is still relatively unproven and commercially challenging, while planting more foreststo act as carbon sinks takes time and eats into the available land to grow food.

Researchers at Utrecht University claimed to have found a way around this challenge last week, with the release of a new paper explaining how the 1.5 degrees target can be reached with a radically scaled down use of negative emissions technology.

Using computer modelling, the scientists found that by using more renewable power and cutting down on agriculture emissions the world can hit 1.5 degrees with substantially less use of negative emissions technology.

Animal production, for example, is responsible for up to 14.5 per cent of global emissions, as well as demanding extensive land and water use and playing a role in deforestation. If humans limited intake of meat and dairy to a healthy amount the pressure to use negative emissions would ease substantially.

Detlef van Vuuren, project manager of the IMAGE project and professor at Utrecht University, acknowledged that such lifestyle shifts may be difficult to deliver. “It is clear that each path comes with its own challenges,” he admitted. “For example, a change in dietary habits entails a large-scale change in the global food system. In any case, each scenario shows a clear break with past trends.”

But the paper notes that such alternative scenarios offer many other global benefits in line with the Sustainable Development Goals, such as improving health and global food supply.

The paper also stressed that ongoing investment in negative emissions technology would be necessary in any scenario in order to meet the 1.5 degree target.

Good News, Bad News For Renewable Energy In New Jersey

17.04.2018

obnovljiva-energija — Foto-ilustracija: Pixabay

When Chris Christie, former governor of New Jersey, wasn’t closing traffic lanes leading to the George Washington Bridge to punish political opponents, he was putting up barriers to renewable energy. Now that he has been consigned to the dustbin of history, his successor, Philip Murphy, is pushing a plan that will help New Jersey realize 50% of its electrical energy from renewables by 2030. That target brings the state in line with similar programs underway in California and New York.

New Jersey, like several other states and many individual cities, is determined to do its part to meet America’s commitments to the Paris climate change accords, despite headwinds from the Trump administration. “If you look at the United States commitments under Paris, these percentages would more than uphold New Jersey’s share of the burden,” Robert C. Orr, the primary science adviser to the UN secretary general, tells the New York Times. Orr is now the dean of the School of Public Policy at the University of Maryland.

“Obviously, New Jersey is a significant state, but it’s not a driver in the same sense that California is,” he says. “But by putting New Jersey in a group with California and New York and then Vermont and Maryland, you start to see, not getting all the way to Paris targets, but you start to see the trend line moving toward us meeting Paris.” Governor Murphy has also been supportive of an initiative to build offshore wind turbines along the New Jersey coast, something Christie openly opposed. The new initiative seeks to build 3,500 megawatts of offshore wind generation by 2030, enough to power 1.5 million homes.

The part of Murphy’s plan that will not please environmentalists is his embrace of nuclear energy. “I believe the biggest bridge we have to our clean energy future are the nukes and, not to mention, the thousands of jobs they support,” he says. New Jersey currently derives nearly half of its electricity from four nuclear power plants. One of those — the Oyster Creek facility — is scheduled to close soon, but Murphy’s plan will shovel $300 million a year to the remaining nukes to keep them going for a few more years. New Jersey rate payers will have the privilege of paying the subsidy.

Nonetheless, some environmental groups feel the need to temper their distaste for the program. “We don’t want to see the abrupt closure of nuclear plants, because if you close them tomorrow, we know that they’ll just be replaced by more fossil fuels,” says Dale Bryk, senior strategic director for the Natural Resources Defense Council. “You have to have an orderly transition plan that involves scaling up renewables first, so that when the nuclear plants close, they’re replaced with clean energy.”

Not everyone is so sanguine, however. “It’s going to put a chilling effect on spending more for renewable energy, because to build out renewable will cost much more,” says Jeff Tittel, director of the New Jersey Sierra Club. “This bill is about a nuclear subsidy, and that’s the primary purpose. And that’s the diversion to make you think you’re getting something that you’re not.”

New York and Illinois have granted similar subsidies to nuclear facilities but they contain a provision the New Jersey legislation does not. Every three years, the companies that operate nuclear reactors in those states will have to open their books to demonstrate they still need the subsidy. The New Jersey nuclear plants will be under no such obligation.

Green energy proponents will complain the subsidies should be used to install more renewable energy facilities and they have a valid point. In the long run, every available dollar should be put to work creating the clean energy grid of the future rather than propping up traditional generating facilities that are no longer economically viable. Still, Rome wasn’t built in a day. Some progress is better than none, especially at a time when federal policy favors a return to the age of steam.

May Announces £60m Fund to Clear Oceans of Plastic ‘Scourge’

17.04.2018

Prime Minister Theresa May has pledged £61.4m in funding to turn the tide against ocean plastic, as part of a new initiative from Commonwealth countries to tackle the problem.

Announcing the move on Saturday, May dubbed plastic waste a “scourge” on the world’s oceans and promised to harness collective action from Commonwealth nations to “effect real change”.

The cash will be split into three pots: £25m into scientific, economic and social research to address sources of plastic waste, £20m to stop plastic pollution from manufacturing in developing countries, and £16.4m to improve waste management in the UK, particularly in cities.

The PM will use a meeting of the 52 Commonwealth nations in London today to urge other countries to join the anti-plastic fight, under a new campaign from the UK and island state Vanuatu dubbed the Commonwealth Clean Oceans Alliance (CCOA).

May hopes other Commonwealth nations will join the CCOA and follow in the footsteps of the UK on tackling plastic waste, by implementing measures such as a microbeads ban or plastic bag charges. New Zealand, Sri Lanka and Ghana have already joined, Downing Street said on Saturday.

“This week we will look closely at how we can tackle the many threats to the health of the world’s oceans, including the scourge of marine plastic pollution,” she said in advance of the summit this week.

“As one of the most significant environmental challenges facing the world today it is vital that we tackle this issue, so that future generations can enjoy a natural environment that is healthier than we currently find it.”

Poor waste management is the single leading cause of plastics in the ocean, and improving waste infrastructure in developing countries will be a major focus of the CCOA, according to Downing Street.

For example, the Department for International Development will fund pilot programmes in up to three Commonwealth developing countries to tackle waste from cities that often ends up in waterways.

Earlier this year the UK promised to eliminate “unnecessary” single-use plastics in the UK by 2042. The pledge came in response to an unprecedented public outcry over the issue following the broadcast of the BBC’s Blue Planet II documentary, which exposed the devastating impact plastic waste is having on ocean wildlife, and high-profile campaigns such as Sky’s Ocean Rescue initiative.

Although measures to hike taxes on single-use plastics are still under development, the response from the business world to anti-plastic sentiment has been dramatic, with firms from PG Tips to Iceland pledging to cut down – or outlaw altogether – single-use plastics from their operations.

Meanwhile, campaigners show no signs of easing up on the issue. Today Sky announced National Geographic has pledged $10m towards the broadcaster’s Sky Ocean Ventures, an investment arm dedicated to supporting business ideas to tackle ocean plastic.

The cash will be used for grants, innovation challenges and events to raise the profile of the plastic problem and fund the development of alternative materials and new, zero-waste manufacturing processes.

Alaskan Glaciers Have Not Melted This Fast in at Least Four Centuries

17.04.2018

Rising temperatures are causing glaciers in Alaska’s Denali National Park to melt faster than at any time in the past 400 years, according to new research.

The study was published in the Journal of Geophysical Research: Atmospheres, a journal of the American Geophysical Union in March. The Earth science organization released details about the research Tuesday.

“We have not seen snow melt like this in at least four centuries,” lead author Dominic Winski, a glaciologist at Dartmouth College, told USA Today.

For the study, Winski and 11 other researchers from Dartmouth College, the University of Maine and the University of New Hampshire examined ice cores drilled from the summit of Mt. Hunter in June 2013.

The ice cores gave the scientists a record of temperatures and climate conditions on the mountain dating back to the mid-17th century. For instance, dark bands of ice with no bubbles indicated that snow on the glacier melted in past summers before re-freezing.

When analyzing the bands, the scientists determined that the site’s summers are at least 2.2-3.6 degrees Fahrenheit warmer now than summers during the 18th, 19th and early 20th centuries. Additionally, rising temperatures are melting 60 times more snow on Mt. Hunter than at the start of Industrial Revolution 150 years ago.

The researchers concluded that the tropical Pacific Ocean, which is warming due to increased greenhouse gas emissions, is contributing to the unprecedented melting of Mt. Hunter’s glaciers.

Winski explained that warmer tropics lead to higher atmospheric pressures and more sunny days over the Alaska Range, which contributes to more glacial melting in the summer.

“This adds to the growing body of research showing that changes in the tropical Pacific can manifest in changes across the globe,” Luke Trusel, a glaciologist at Rowan University in Glassboro, New Jersey who was not involved with the study, said in a statement. “It’s adding to the growing picture that what we’re seeing today is unusual.”

It is important to understand how mountain glaciers are affected by climate change because they provide fresh water to many communities and their melting can contribute to sea level rise, Winski noted.

“The natural climate system has changed since the onset of the anthropogenic era,” he said. “In the North Pacific, this means temperature and precipitation patterns are different today than they were during the preindustrial period.”

MHI Vestas Unveils New SMART Tools For Turbine Optimisation & Cost Reductions

16.04.2018

MHI Vestas Offshore Wind unveiled a new suite of next-generation SMART tools this week that are designed to enhance offshore wind turbine optimization and provide better turbine monitoring, thereby allowing for “significant” cost savings for developers and operators.

Announced on Wednesday, MHI Vestas unveiled its MVOW SMART Turbine products, a new trademark suite of tools that will provide customers with the tools to enhance design assessments, offshore wind turbine monitoring, and real-time decision-making. According to the company, it is “pushing boundaries inside the turbine and could now lay claim to having the world’s smartest available turbine.”

“We are not content to just manufacture the world’s most powerful turbine,” boasted Henrik Baek Jorgensen, Head of Product Management, referring to the recent installation of an MHI Vestas V164-8.8 MW offshore wind turbine at the European Offshore Wind Deployment Centre (EOWDC). “We know that our customers require world-class production and operation of the turbine in every area. This product portfolio addresses their most critical business needs and gives them an unprecedented level of visibility and control.”

MHI Vestas’ new MVOW SMART Turbine suite is made up of four separate products:

SMART Foundation Loads, which optimizes foundation design upfront. The software package will allow MHI Vestas customers to perform integrated load design simulations prior to undertaking detailed load assessments, using a range of options and scenarios.

SMART Dampers are designed to actively reduce fatigue loads. Active SMART Dampers reduce fatigue and design loads by reducing the side-to-side and fore-aft movements of the tower and also help to extend the use of monopile foundations to more challenging sites where rougher conditions can cause heavier loads.

SMART Fast Data is billed as being able to dramatically increase the data flow from the turbine. Receiving data frequency 600 times faster than traditional SCADA methods from the nearly 1000 sensors in a turbine, the tool unlocks hidden insights, enhances diagnostic capability, and optimizes scheduled service.

SMART Performance Monitor brings wind power plant monitoring to a hand-held device. Feeding real-time information on turbine performance, site production, and operational notifications to any mobile device, the Performance Monitor puts the wind park into the customer’s pocket.

“Our ambition is to not only have the most powerful products, but also the smartest products in offshore wind,” Jorgensen added. “This portfolio is the latest example of how we’re taking digitalisation to the next level and reflects our singular commitment to optimise our customers’ business case.”

The move comes on the heel of several recent MHI Vestas announcements which underline the company’s plans to continually develop new and groundbreaking technologies, while at the same time expanding its share into new global markets. As mentioned, an MHI Vestas V164-8.8 MW wind turbine was recently successfully installed at the European Offshore Wind Deployment Centre off the coast of Scotland — the most powerful wind turbine to be deployed for commercial application.

Towards the end of March, MHI Vestas also signed four separate Memorandums of Understanding with companies in Taiwan to begin building out its supply chain in the region. Taiwan has been a recent hotbed of offshore wind industry attention, and MHI Vestas has been quick to similarly jump into the region.

Pakistan Can Spur Social & Economic Development With Renewable Energy, Claims IRENA

16.04.2018

The International Renewable Energy Agency has published a new analysis of Pakistan’s energy sector which shows that the country can spur both social and economic development and improve its energy security by developing its “abundant” renewable energy sources.

In a new report published earlier this week, Renewables Readiness Assessment Pakistan, the International Renewable Energy Agency (IRENA) made the case for developing Pakistan’s “abundant renewable energy resources that can be utilised for power generation and end-use sectors.” Specifically, there is a significant need to address what the authors of the report described as “a widening gap between power demand and generation” that stems from “continued growth in energy demand and inadequate investment in generation infrastructure.” Specifically, Pakistan’s gap between demand and supply reached as much as 7 gigawatts (GW) in 2012, but slowly swung back to between 4 GW and 6 GW.

Unsurprisingly, this is not just a matter of statistics, and instead has a direct impact on the lives of Pakistanis and the economic and social development of the country.

According to IRENA, hydropower has traditionally been Pakistan’s predominant form of renewable energy and makes up 7.1 GW worth of the country’s grid-connected capacity, but could be expanded to up to 60 GW. IRENA’s assessment of Pakistan’s renewable energy potential also identified 50 GW of possible wind energy capacity and up to 25 million tonnes of biomass feedstocks from industrial and agricultural residue per year.

Currently, Pakistan has nearly 600 megawatts (MW) of wind power, 400 MW of solar PV, 50 MW of small hydropower, and 160 MW from biomass. Further, Pakistan has another 2,000 MW worth of renewable energy currently under development.

Looking at solar PV specifically, the authors of the report highlight the country’s high levels of solar irradiation, specifically in the country’s south and southwest. While no specific GW capacity was given, the authors of the report also pointed to several letters of intent across several states which are paving the way for more solar capacity in the near-future. Pakistan’s solar industry is still in its early stages, but it still boasts employment of more than 15,500 people, most of which are involved in small-scale residential and commercial deployment.

“Pakistan is undergoing rapid economic and industrial development, which in turn is fuelling strong energy demand growth across the country,” said Adnan Z. Amin, IRENA Director-General. “To meet this demand Pakistan has a tremendous opportunity to cost-effectively tap its abundant solar, wind and hydropower resource potential. Doing so would support national prosperity and job creation, whilst enhancing security of supply, improving access and moving Pakistan towards greater energy independence.”

“Pakistan is rich in renewable energy potential, and can with this assessment develop policies, investment opportunities and energy development actions to harness it,” said Abid Sher Ali, Pakistan’s Minister of State for Power. “Critical to this report has been IRENA’s valuable policy guidance and technical assistance to determine our best available renewable-based power options.”

Siemens Gamesa Renewable Energy this week announced that it had passed 5,000 megawatts (MW) worth of wind energy connected to the Indian grid, becoming the second largest manufacturer in India.

Announced on Thursday to coincide with a visit to India by Markus Tacke, Siemens Gamesa Renewable Energy’s CEO, the company revealed that it had successfully connected 5,000 MW to the Indian grid since first entering the company’s wind market in 2009. Since then, Siemens Gamesa has become the second largest wind energy original equipment manufacturer (OEM) based on cumulative installed capacity, and has been the market leader for the past three years.

Specifically, Siemens Gamesa has operations across seven key states for wind energy in India, and a strong industrial presence across the country, with two blade facilities in Nellore (Andra Pradesh) and Halol (Gujarat), a nacelle factory in Mamandur (Chennai, Tamil Nadu), and a repair center in Red Hills (Chennai, Tamil Nadu).

“It is encouraging to see our incremental growth in India over the years. India is a key market for us and will continue to be one for years to come,” said Markus Tacke. “The global wind market dynamics are changing and so is the change occurring in India. Hence, it is imperative for us to respond to the market with more agility, better products and comprehensive digital intelligence which will set us to the path for strong profitable growth, and our L3AD2020 program will set us on track to global leadership.”

“With a dynamic market scenario like ours, we will be introducing new technologies and products specifically designed for the Indian wind and market conditions, thus delivering more value for our customers,” added Ramesh Kymal, Siemens Gamesa Onshore CEO for India.

2 Kilometers of Electrified Road in Sweden — A Pilot for EV-Charging Roads

16.04.2018

E-roads, nedläggning av elskena, Arlanda — Foto: eRoad Arlanda

An “electrified road” that allows vehicles to charge en route has opened near Stockholm Airport in Sweden. It’s currently a 2 kilometer stretch along a high-traffic shipping route.

The constant flow of trucks shuttling containers and loads of cargo between the Stockholm Arlanda Airport and a nearby shipping hub made it an easy target for the pilot project. The effort, naturally, is part of Sweden’s efforts to slash consumption of imported fossil fuels used for transportation. Aside from climate and air quality concerns, this is part of a larger energy independence initiative.

The system uses 50 meter segments of fixed tracks of electrified rails that are physically installed into the road itself. Those are then energized when a vehicle is overhead looking to charge. Communications between the vehicle and the system monitor usage of the system. Thus, drivers or fleet managers can be billed for energy consumption.

Hans Säll, chief executive of the consortium managing the initial phase of the electrified road, believes the technology is also very safe: “There is no electricity on the surface. There are two tracks, just like an outlet in the wall. Five or six centimetres down is where the electricity is. But if you flood the road with salt water then we have found that the electricity level at the surface is just one volt. You could walk on it barefoot.”

Leaders in the space believe that installing fixed charging infrastructure along high-traffic routes would allow drivers to purchase electric vehicles with smaller batteries, lowering the amount of non-value add weight and lowering upfront capital purchase costs.

Scrolling through the project timeline for eRoad Arlanda shows both the long history of electric vehicles and the rapid progress in the last 18 months, with new pilots and products evolving rapidly.

The electric charging road has grown in fits and starts, with the initial trial stretch of 200 meters installed in 2012 then adding tens and hundreds of meters at a time to reach its current length of nearly 2 kilometers of electrified roadway (the situation today).

The consortium running the pilot, eRoad Arlanda, has partnered with PostNord, the first company to use the new electrified roads. In an exciting twist, Hans Säll, chief executive of the eRoadArlanda consortium, shared that he believes that both current electric vehicles and existing roadways could be modified to use the new format if the standard is adopted.

Looking to the future, there is a lot of work to do in order to bring dynamic conductive electric vehicle charging to reality in Sweden or anywhere else. Säll shared that,“If we electrify 20,000km of highways that will definitely be be enough. The distance between two highways is never more than 45km and electric cars can already travel that distance without needing to be recharged. Some believe it would be enough to electrify 5,000km.”

The utopian future is easy to talk about, but what about the cost? At an estimated cost of just €1000 per kilometer, the system is surprisingly cost effective, making the system a compelling option for eliminating transportation emissions in favor of low-range electric vehicles.

Will Sweden commit to the technology to kick transportation emissions to the curb? Time will tell, but the results from the initial pilot so far paint a compelling picture. Looking forward, the next milestone is whether or not the market will support purchasing or converting vehicles to start making use of the existing track.

Blenheim Palace to Phase Out Single Use Plastic

16.04.2018

Oxfordshire stately home Blenheim Palace has become the latest British attraction to announce plans to cut plastic waste on its grounds.

The 300-year old estate said on Friday it is phasing-out single use plastics by replacing plastic straws with paper ones, banning the sale of plastic water bottles and using china instead of paper cups in its cafes. Meanwhile, bin liners are now biodegradeable and disposable cutlery is compostable.

Blenheim Palace’s sustainability advisor Jacqueline Gibson said the estate was also sharing its plastic waste knowhow with other shops and organisations in the local area.

“We are working in partnership with Friends of the Earth Oxford and Sustainable Woodstock, to share best practice with other local shops and organisations to reduce single use plastic,” she said.

“In the past year we have provided environmental training to 82 per cent of staff, commissioned external consultants to host a Waste Workshop for senior teams, and standardised the way waste is segregated and stored for recycling across all offices and work areas,” she added.

The drive to eliminate single-use plastics forms part of Blenheim’s Palace’s wider sustainability strategy, which includes a target to become a net producer of renewable energy over the next decade via its solar array, hydro-powered cylinder and two biomass boilers.

Plastic Bag Bans Actually Work, Study of European Waters Shows

15.04.2018

If you ever feel like the world’s plastic nightmare might never end, a new study shows proof that plastic pollution legislation actually works.

There are significantly fewer plastic bags on the seafloor ever since a number of European countries introduced fees on the items, according to a 25-year study from the UK government’s Centre for Environment, Fisheries and Aquaculture Science (CEFAS).

Researchers found an estimated 30 percent drop in the number of plastic bags in waters around Norway, Germany, northern France and Ireland.

“It is encouraging to see that efforts by all of society, whether the public, industry, NGOs or government to reduce plastic bags are having an effect,” Thomas Maes, Marine Litter Scientist at CEFAS, said in a statement.

“We observed sharp declines in the percentage of plastic bags as captured by fishing nets trawling the seafloor around the UK compared to 2010 and this research suggests that by working together we can reduce, reuse and recycle to tackle the marine litter problem.”

Ireland and Denmark were the first two countries to introduce levies for single-use plastic bags in 2003. A number of European countries followed. In 2015, England became the last country in the UK to introduce a fee.

The study, published in the journal Science of The Total Environment, was based on 39 independent scientific surveys of the distribution and abundance of marine litter on seabeds of the North Sea, English Channel, Celtic Sea and Irish Sea between 1992 and 2017.

Plastic trash such as bags, bottles and fishing debris were commonly observed over the entire 25-year period, with 63 percent of the 2,461 trawls containing at least one plastic litter item.

In a statement, Richard Harrington from the Marine Conservation Society said the decrease in the number of plastic bags recorded in the surveys is “very encouraging.”

“It shows that fiscal measures can work—charging for what was once a free item, often used just once and thrown away, has had a real influence on consumer behavior without genuinely hurting people in the pocket,” Harrington said.

However, even though fewer plastic bags were recorded, the researchers found widespread distribution of other plastic items on the seafloor. They also noted a significant upward trend of fishing debris.

This means plastic bag legislation is merely a start in reducing the 8 million tons of plastic waste that gets dumped into our oceans every year.

As WWF UK tweeted, “Great to see less plastic bags in our oceans, but we need the government to put an end to the use of all avoidable single-use plastic by 2025.”

In March, the UK government released a startling report warning that plastic pollution in the world’s oceans is projected to increase three-fold within seven years unless action is taken.

The Future of the Sea report found that human beings across the globe produce more than 300 million metric tons of plastic per year. Unfortunately, a lot of that material ends up in our waters, with the total amount of plastic debris in the sea predicted to increase from 50 million metric tons in 2015 to 150 million metric tons by 2025.

To solve this plastic epidemic, the authors suggested solutions that range from preventing plastic from entering the sea, introducing new biodegradable plastics, and campaigns that raise public awareness about marine protection.

New Satellite Could Help Rat Out Methane Polluters

15.04.2018

As greenhouse gases go, methane is a heavy hitter – one with a heat-trapping ability 25 times that of carbon dioxide (CO2) over the course of a century. As the second-most abundant greenhouse gas after CO2, slowing methane emissions could make a huge difference in limiting the effects of climate change. The Environmental Defense Fund (EDF) has decided the best way to do this is to play a little “I Spy.”

The EDF will launch a satellite in the next three years that specifically seeks out methane leaks from the atmosphere, NPR reports. These leaks can be human-caused (often from oil and gas operations), come from natural wetlands, or arise as the – er – byproducts of cows. These emissions can be difficult to track sans-satellites, as the gas spreads as it rises, making ground and air measurements patchy.

Experts also told NPR that on-the-ground inspections of oil and gas operations may fail to detect these leaks because companies hide them before arranged inspections.

The question that remains is: will this satellite really deliver more information than existing detection methods? Satellites currently in the atmosphere can measure methane, but the picture they paint is blurry, making it harder to find sources of the gas. The MethaneSAT, as it’s to be called, won’t necessarily be high-resolution enough to pinpoint an individual farm or oil well that’s leaking. However the EDF says that its ability to track methane over time could help lead inspectors to the right place.

Meanwhile, here on the ground, individuals and organizations could make an even bigger difference by cutting methane off at the source. Perhaps surprisingly, fermentation in the stomachs of agriculture animals makes up the biggest chunk of methane emissions in the world (29 percent), closely followed by oil and gas (20 percent).

While reducing our dependency on fossil fuels plays a huge role in cutting methane pollution, we’re going to have to get a little more creative when it comes to reducing agricultural sources. Scientists are fiddling with cows’ diets to see if different foodstuff could make cow flatulence a little less heat-trapping, and even hacking their gut bacteria.

Of course, there is also the option of simply eating less meat. But that’s another story.
