Rather than dismantle coal plants, why not create a clean fuel that can be used in the same plants, utilising the steam turbines, existing connections to the grid, and preserve jobs at the plant. MGA (miscibility gap alloy) is that fuel, say Erich Kisi and Alexander Post at the University of Newcastle, Australia who are behind the development of these blocks of material, 20cm x 20cm x 16cm, made of blended metals. They are heated up â using … [Read more...]

Gas oversupply and clean energyâs rise: now is the time to fast-track gas market reforms
Traditional monopolistic and oligopolistic gas markets artificially keep gas prices high, work against competition and efficiency, and have no place in the modern world, say Jean-Baptiste Dubreuil, Gergely Molnar and Songho Jeon at the IEA. They calculate that gas market reforms in the EU, begun in the mid 1990s, saved the bloc $15bn in 2019. But it typically takes 20 years for such a market to be properly established. The authors explain that … [Read more...]
ANEEL: Thorium-based reactor fuel could revive Nuclearâs fortunes
A public-private consortium backed by the U.S. DoE is developing a new nuclear fuel â a mix of thorium and uranium â that looks like a major advance on the fuels currently in use, says Jim Conca. Called âAdvanced Nuclear Energy for Enriched Lifeâ (ANEEL), it has a very high fuel burn-up rate (55,000 MWd/T) compared to the usual uranium (7,000 MWd/T). That high burn-up reduces the waste by over 80%. Less spent fuel means less refuelling, less … [Read more...]
Swedenâs new âprosumersâ: electricity generation at the city, village and residential level
54% of Swedenâs power already comes from renewables â the target is 100% by 2040 - and more and more is being generated locally on a small distributed scale, says Harry Kretchmer writing for the World Economic Forum. âDistrict Heatingâ plants are today using excess heat to warm over 75% of Swedish homes. Residential generation is happening too, creating âprosumersâ who both produce and consume. In Ludivika, 1970s flats have been retrofitted with … [Read more...]
The Energy Charter Treaty needs updating, but remains a valuable tool for the transition
Last Thursday we published this critique of the Energy Charter Treaty (ECT). Created in the 1990s, the ECT was designed to protect cross-border energy investments from political risk. Critics now say it is being used to protect fossil fuel investments in a world committed to phasing them out. Today, Andrei Belyi of energy consulting firm Balesene OU and Adjunct Professor in Energy Law and Policy at the University of Eastern Finland, who was named … [Read more...]
Perovskites: the next generation of solar cells and lighting?
Enthusiasm about the discoveries being made about perovskite materials is spreading, explains Sam Stranks at the University of Cambridge. Perovskite solar cells hit 25.2% efficiency in 2019, not far off crystalline silicon cells at 26.7%. Research is suggesting that figure could rise higher still. Perovskite can be âtunedâ to absorb particular frequencies of light, allowing different layers of perovskites to absorb different and therefore more … [Read more...]
No more âoffsettingâ: Google commits to 24/7 locally sourced carbon-free electricity by 2030
By âoffsettingâ fossil electricity consumed at one data centre through buying green power from somewhere else, Google has been 100% renewable since 2017. But offsetting always has its flaws. In this case, 40% of Googleâs actual power still comes from fossil fuels. Googleâs new plan, to be 100% green 24/7 straight off the local grid, is designed to solve that. It will also send market signals to increase clean capacity locally, not just where you … [Read more...]
BP Outlook 2020: âpeak oilâ has already happened
BPâs latest Outlook predicts â for the first time - that oil saw its peak in 2019. In each of BPâs Outlooks, published annually since 2011, they have revised their predictions for the global energy landscape to 2050 as new data comes in. The growth of clean energy and the changing shape of climate policies have seen each successive forecast increase the share of renewables at the expense of fossil fuels. This year even gas has seen its prospects … [Read more...]
Norwayâs power markets, storage and CCS plans can make it a decarbonisation hub for Europe
Though still heavily reliant on oil and gas, Norway can claim to be a central piece in Europeâs decarbonisation puzzle, explains Tshin Ilya Chardayre writing for the IFRI Centre for Energy & Climate. Norwayâs substantial hydropower infrastructure gives it a reservoir storage capacity that could account for 10% of EU-wide energy storage needs by 2050. That would require international transmission cables and power markets, the development of … [Read more...]
Energy Charter Treaty: reform will only happen when energy ministers get involved
Negotiations are underway for the reform of the Energy Charter Treaty (ECT), an international trade agreement under fire from former Energy Charter executives, members of the European Parliament, and NGOs. Created at the end of the cold war, it was designed to protect cross-border energy investments â in a fossil fuel world â from political risk. Clare Taylor quotes the critics who say it no longer makes sense for the treaty to protect oil and … [Read more...]
Grid scale Battery costs are declining faster than Wind and Solar
Gas as a transition fuel for grids may be around for a lot less time than we thought. We already know that large batteries, if they are cheap enough, can replace gas plants to provide peaking power to grids reliant on intermittent wind and solar. Bruce Robertson at IEEFA says the numbers are showing battery costs declining even more rapidly than wind and solar. Precisely because of that increased competitiveness Australiaâs AGL Energy is starting … [Read more...]
Hydrogen, CCS, and more: without new clean energy technologies we cannot hit our 2050 emissions targets
The flagship 400-page report, Energy Technology Perspectives 2020, is another salvo from the IEA to concentrate the minds of the world on new technologies and their roll out. Thatâs because transforming electrification and the power sector alone, where most of the progress is happening, will only get us one-third of the way to net-zero emissions by 2050. The IEA has analysed over 800 new technology options. The most important categories â … [Read more...]
The expansion of Europeâs EV charging infrastructure: new rules and incentives needed
In 2021 the Alternative Fuels Infrastructure Directive, which regulates public charging infrastructure, will be revised and updated by the European Commission. Referencing her study, Julia Hildermeier at RAP identifies some of the rules and incentives that will be needed to optimise the expansion of EV charging infrastructure. To start with, she says that EU countries need to define the baseline essential charging network. Such a promise would … [Read more...]
City-level emissions reductions: what can successful cities teach us
The EU Covenant of Mayors for Climate and Energy (EUCoM) requires their member cities to commit to exceeding their national goals. EUCoM is one of the worldâs largest subnational climate action networks, with over 1,000 cities and home to 50m people. Writing for Carbon Brief, Angel Hsu, Nihit Goyal and Amy Weinfurter at Yale-NUS College review the data to see how successful they have been. About 40% of the cities show emission reductions that are … [Read more...]
Cooling: up-front costs are the barrier to new solutions that cut energy use by two-thirds
Existing, latest technology could be delivering the worldâs current air conditioning needs with just a third of the energy use, say Sneha Sachar at the AEEE (India) and Iain Campbell at RMI. The main barrier is the up-front costs. And thatâs for everything from improving the thermal efficiency of buildings to accelerating the deployment of the most efficient cutting edge ACs (at present, legal minimums lag behind the best ACs, and the best ACs … [Read more...]
