Pumped Storage Hydropower (PSH) is one of the most cost-effective utility-scale options for grid energy storage. The U.S. has plants across the country, totalling over 20GW of capacity. Now the Dept of Energy (DoE) is backing four teams developing blue sky (water?!) ideas that should make the next generation of PSH even cheaper. In this article the National Renewable Energy Laboratory (NREL) tracks their progress so far. They include dams made of … [Read more...]

BPâs zero-carbon pledge: three major challenges
This month BP, one of the worldâs largest oil and gas firms, announced its ambition to be a net zero emissions company by 2050. The promise extends to cutting the emissions of its customers too; after all, theyâre the ones who are actually burning the fuel, not BP. So it aims to reduce the carbon intensity of its products by 50% by 2050 or sooner. Jules Kortenhorst, Tyeler Matsuo and Raghav Muralidharan at Rocky Mountain Institute take a look at … [Read more...]
Machine learning cuts new EV battery design testing times by months, years
Normally, battery prototype testing can take months and years to find the optimal design for fast-charging and battery life. Now scientists from Stanford, MIT and the Toyota Research Institute have developed a machine learning programme that can cut battery testing times by 98%. Theyâve applied it to EV batteries. The faster a new and improved design is proven and taken to market the more rapid the uptake of EVs weâll have. Matthew Vollrath at … [Read more...]
What if Germany wasnât shutting down Nuclear? Modelling Coal, Gas, Renewables, emissions, prices
Germany plans to shut down its entire nuclear fleet by 2022. Right now, of the original 17, only 7 are still running. The Fukushima nuclear accident in Japan of 2011 was the trigger for Germanyâs abandonment of emissions-free nuclear as part of its clean energy goals. Maximilian Auffhammer at the Energy Institute at Haas reviews a paper by his colleagues that has modelled the whole-system effects of the shutdowns, then compared the results with a … [Read more...]
Polandâs PGE: profits from Renewables can replace declining Coalâs
Polandâs PGE is one of Europeâs most fossil fuel intensive energy firms. Coal makes up around 90% of its electricity generation. Itâs been investing around PLN 28bn ($7.2bn, âŹ7bn) to build three new coal power plant units, acquire the Polish coal assets of Franceâs EDF, and upgrade its existing fleet to meet air quality standards. But a new and detailed report from IEEFA warns that the profitability of these investments will decline in the 2020s … [Read more...]
Canada is launching methane emissions rules for Oil and Gas
January 2020 marked the first time the Canadian government has targeted methane emissions from the oil and gas sector. Theyâve committed to reduce oil and gas methane emissions by 40% to 45% below 2012 levels by 2025. Reducing methane emissions is considered one of the most cost-effective ways to cut global emissions. Methane equates to around 5.4% of the countryâs total emissions of 716 Mt CO2-eq. The IEA estimates global methane emissions from … [Read more...]
Even cycling Coal is losing money. Only âsummerâ coal makes sense in Texas, Louisiana
Joseph Daniel at the Union of Concerned Scientists says a detailed look at the U.S. data shows the days of coal plants being the baseload kings are numbered. The declining costs of wind, solar and gas are making coal look expensive. Whatâs more, increasing energy efficiency is flattening peak demand (and therefore prices), squeezing those periods when coal could rely on finding customers. That means coal plant owners that say they deserve support … [Read more...]
60 years on, OPEC should take control again, cut supply, raise prices to fund its Transition
OPEC is often seen as no friend of the Transition. But Greg Muttitt points out that, although it did take an anti-climate stance in the 1990s, by the 2000s it had stepped back from climate negotiations, while some OPEC members became supporters. Muttitt says that, celebrating its 60th anniversary, itâs time for OPEC to remember its roots and organise its members to take control of their own destiny in the face of the inevitable rise of clean … [Read more...]
Germany must put CCS back on the table, says Merkel
Carbon Capture has not been popular in Germany. The public are largely opposed, political parties are split, and Federal States are not approving new projects. Germany has only four operations, and only one has injected anything (not much) into the ground. Now Chancellor Merkel wants it back on the table, along with a public debate. Julian Wettengel at Clean Energy Wire runs through the reasons for the opposition (an excuse to keep coal plants … [Read more...]
UK to phase out petrol, diesel, hybrid car sales by 2035. Hereâs how
This month the UK government promised to accelerate the phase-out of fossil-fuelled cars. From 2035 all new diesel and petrol car sales (including hybrids) are banned. Promises are one thing, realistic policies, plans and investment is another. Last year only 1.6% of new passenger vehicles sold were EVs and that has to rise to 100% in 15 years. Ashley Fly at Loughborough University sets out what needs to be done. First, skills and training; much … [Read more...]
Norwayâs âNorthern Lightsâ project: creating the CCS business model
Northern Lights, a carbon capture and storage (CCS) project backed by the Norwegian government, is drilling test wells in the North Sea to find suitable places to store CO2. Project partners include Shell and Total, and others are joining them. CO2 will be shipped to an onshore terminal from which it is piped to the subsea wells. Once established, the plan is for other European countries to send their CO2 too. The project will also create the … [Read more...]
Defining green investments, ending greenwash: the EUâs new Taxonomy Regulation
When the EU Commissionâs new Taxonomy Regulation is approved, expected in March, it will provide the legal framework to define what is a truly âgreenâ investment. As Luca Bonaccorsi at Transport & Environment explains, right now asset managers and national authorities are free to define what is green, allowing some to greenwash investments in things like oil and pesticides. The Taxonomy's purpose is to reduce ambiguity and therefore increase … [Read more...]
Tech-Neutral Auctions for Renewable Energy: are poorly defined rules creating loopholes?
The ECâs Environmental and Energy State Aid Guidelines 2014-2020 (EEAG) require Member States to implement technology-neutral auctions as part of their renewable energy support schemes. However, the reality looks quite different, write Bastian Lotz and Silvana Tiedemann from Navigant (a Guidehouse company), Lars Jerrentrup of Aurora Energy Research, and Lion Hirth from Neon. Most Member States continue to use technology-specific auctions, using … [Read more...]
200 â 400 Nuclear reactors to be decommissioned by 2040
Denis Iurchak has taken a close look at nuclear decommissioning. Globally, 447 nuclear reactors are in operation as of January 2020. Of those, nearly 70% are older than 30 years (25% are older than 40 years). The IEA says around 200 commercial reactors are to be shut down in the next two decades. On top of that, 182 reactors are already in permanent shutdown. This means that between 200 and 400 reactors are likely to be decommissioned by 2040, … [Read more...]
100% renewables by 2050: a technology, market, system, business model toolset for your nation
A growing number of countries are announcing increasingly ambitious renewable energy targets. But how do you deliver the results? IRENAâs Elena Ocenic explains that they have developed a toolset for countries to plot their unique pathway to success. Those tools range widely across technology, market design and regulation, system operation practices, and business models. The article lists the tools, and runs through some notable successes. Ocenic … [Read more...]
