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 “tuned” to absorb particular frequencies of light, allowing different layers of perovskites to absorb different and therefore more … [Read more...]
No more “offsetting”: Google commits to 24/7 locally sourced carbon-free electricity by 2030
By “offsetting” 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 Google’s actual power still comes from fossil fuels. Google’s 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: “peak oil” has already happened
BP’s latest Outlook predicts – for the first time - that oil saw its peak in 2019. In each of BP’s 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...]
Norway’s 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 Europe’s decarbonisation puzzle, explains Tshin Ilya Chardayre writing for the IFRI Centre for Energy & Climate. Norway’s 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 – in a fossil fuel world – 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 Australia’s 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. That’s 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 – … [Read more...]
The expansion of Europe’s 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 world’s 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 world’s 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 that’s 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...]
“Vertical well” Pumped-Storage Hydro: small, cheaper, 1-to-100MW range
In the U.S., pumped-storage hydropower (PSH) already provides 95% of all utility-scale energy storage. So any innovations that cut costs or extend PSH usability should be well received. The National Renewable Energy Laboratory (NREL) and its partners Obermeyer Hydro, Microtunneling Inc. and Small Hydro Consulting are demonstrating the advantages of a small pump installed in a vertical “well” rather than an underground powerhouse, one of the most … [Read more...]
E-Trucks need infrastructure, not just cheaper batteries
The electrification of road freight has great potential, but there are some big gaps that first have to be bridged. Writing for IRENA, Dolf Gielen, Francisco Boshell, Guy Lentz and Sita Holtslag explain what needs to be done to ensure that the technological advances and cost reductions happening at the forefront of e-mobility are quickly delivered onto our roads. To illustrate the problem: in Europe over half of road freight is transported less … [Read more...]
Will Saudi Arabia build the world’s largest green hydrogen and ammonia plant?
The Gulf is already a major producer and consumer of hydrogen, mainly for fertilisers and specialty chemicals. Like most hydrogen produced globally, it is the ‘grey’ kind made from hydrocarbons. But the region’s low renewable power costs and abundance of land give it the key components for the industrial scale production of green hydrogen. So in July, the Saudi model city of Neom (Neom means “new future”) and ACWA Power signed a joint venture … [Read more...]
Zero U.S. power sector emissions by 2035, says Biden. How?
Joe Biden, the Democratic presidential hopeful, wants to reduce U.S. power sector emissions to zero by 2035. That’s more ambitious than Obama, and more than what Biden promised when campaigning to be the Democrat’s candidate. His emphasis has been on the jobs and investment a green economy will create – language that has more voter appeal than reversing emissions. Meredith Fowlie at UC Berkeley’s Energy Institute at Haas reviews the promises … [Read more...]
France’s recovery plan: will support for emissions-high sectors compromise a new Green economy?
The French recovery plan, formally presented today, combines emergency rescue measures, economic stimulus and longer-term investments. A substantial €32bn out of the €100bn budgeted is earmarked for the green economy. But Sébastien Treyer at IDDRI asks whether rescue measures for traditionally emissions-high sectors - tourism, aviation, automotive, buildings, agri-food – will collide with climate targets. He references studies that should be used … [Read more...]
