Germanyâs Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz/EEG), now 20 years old, is under discussion as a new amendment is supposed to come into force on January 1st 2021. Simon Göss at Energy Brainpool takes a detailed look at the highlights, including the new and higher targets, the financial role of municipalities, clean electricity subsidies, and solar and wind tender volumes. He explains there has been serious criticism of the … [Read more...]
Floating Solar on existing Hydro reservoirs: potential for 10,600 TWh/year
The idea is simple. Float solar panels on the reservoirs of hydroelectric dams. The new solar can piggy back on the existing grid connections. They complement each other by being strong when the other is weak: solar for the dry season, hydro for the wet. The hydro can provide pumped storage for the excess solar. Finally, the reservoir is readily available space. A team at the U.S.'s National Renewable Energy Laboratory have calculated the … [Read more...]
Changes to national targets and forestry mean ECâs 55% plan is weaker than it looks
The ECâs plan to reduce the blocâs emissions by 55% by 2030 compared to 1990 levels, instead of the previously agreed 40%, is very welcome but its implementation plan is flawed, says William Todts at Transport & Environment. The EU Emissions Trading System (EU ETS) wonât be enough on its own. So the plan allows nations to include âmanagingâ forests and âtree plantationsâ, a big change because forests were not part of previous emissions … [Read more...]
Europeâs 55% emissions cut by 2030: proposed target means even faster coal exit
The EC is proposing a target emissions reduction of 55% by 2030 compared to 1990 levels, instead of the previously agreed 40% (which the EU is on course to surpass). The main tool for achieving it will be the EU Emissions Trading System (ETS). Prices for allowances will rise, making coal increasingly uncompetitive. Sören Amelang, Kerstine Appunn and Julian Wettengel at CLEW talked to a number of experts who say the new target implies a near total … [Read more...]
Teslaâs BEVs vs. Toyotaâs hybrids: the battle for the future of low emission cars
Which car firm will dominate the future? Tesla and its BEVs or Toyota with its hybrids? Schalk Cloete looks at the cost reductions coming down the line. He says that the hybrids have many more improvements on the way, whereas in terms of performance and efficiency the BEVs are already reaching their peak. Though further and considerable progress in battery technology is coming, it will benefit both. For city driving both will rely on battery … [Read more...]
Net Zero by 2050 technically and economically achievable, says Energy Transitions Commission report
Making Mission Possible, the latest report by the Energy Transitions Commission, describes a net-zero world by mid-century as technically and economically possible. The solutions are already available or close to being brought to market. What is still missing is the will to embrace, rapidly and at scale, the inevitable disruption that will ultimately deliver net-zero emissions, lower air pollution, cheaper energy bills, create new jobs and raise … [Read more...]
MGA blocks can substitute for coal, preserving plants, grid connectivity and jobs
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...]
