In May this year Spain reached a landmark day when it was powered 100% by renewables - solar, wind and hydroelectric power - from ten o'clock in the morning until seven o'clock in the evening. In four years the share of renewable energy generation rose from 37% to 50%, while non-renewables dropped from 62% to 49%. Its draft Law on Climate Change and Energy Transition targets 35% of renewable energy in final consumption by 2030 and 100% in the … [Read more...]
Sodium-ion batteries ready for commercialisation: for grids, homes, even compact EVs
Sodium-ion (Na-ion) batteries, a much more abundant and cheaper alternative to the standard Lithium-ion, are on the verge of commercialisation, explain Carlos Ruiz, Martina Lyons, Isaac Elizondo Garcia and Zhaoyu Wu at IRENA. Though thereâs enough Lithium in the world to support global electrification targets, tightening demand and supply chain constraints point at the urgent need for an alternative. The cost of a Na-ion battery cell is expected … [Read more...]
Rooftop Solar for industry: up to 35% of U.S. manufacturing sectors could supply all their own power
Rooftop solar could supply the complete electricity needs of 5-35% of U.S. manufacturing sectors, explains Matthew Eckelman at Northeastern University who summarises his co-authored paper âTechnical feasibility of powering U.S. manufacturing with rooftop solar PVâ. At present, only 0.1% of industrial electricity demand in the U.S. is supplied by on-site sources of renewable energy. But large, unobstructed industrial rooftops and the declining … [Read more...]
Europeâs grid bottlenecks are delaying its energy transition
***While you're here... REGISTER NOW for "REPowering the grid for Solar PV" with the Vice-President of Tauron, DG ENER C, Eurelectric and SolarPowerEurope - Online Wednesday September 20 from 11:00 to 12:15 CEST*** No amount of record sales and deployment in Europe of heat pumps, EVs, solar farms, wind turbines and all the rest will guarantee the region meeting its electrification targets if the grids arenât ready to integrate them. As … [Read more...]
Does Nuclear slow down the scale-up of Wind and Solar? France and Germany canât agree
France and Germany lead the camps in disagreeing on the future of nuclear in Europe. Camille Lafrance and Benjamin Wehrmann at CLEW take a deep dive into the reasons why, quoting experts and politicians. Germanyâs vision of a fully renewables-based EU is at odds with Franceâs unwavering support for low-carbon nuclear energy. European-wide agreement on targets matter because they drive future investment in the targeted technologies and the design … [Read more...]
Only certain types of Hybridisation (Wind or Solar + Storage) beat building expensive transmission lines
In some regions, the roll out of new wind and solar has outpaced new transmission. That causes âcongestionâ at times when the variable renewables are producing too much power locally, and cannot sell the excess, which squeezes profitability. Thatâs certainly the case in the U.S. now. One answer is âhybridisationâ where storage is built alongside the renewables, to save that excess power for when it can be sold later. Julie Mulvaney Kemp at … [Read more...]
âFlow Batteriesâ for grid-scale storage: modelling cheaper alternatives to Vanadium
Flow batteries are a promising new technology for grid storage. Rather than the standard batteries that store charge in a solid material, they use a solution to store that charge, making large-scale long-duration electricity storage much easier. Vanadium electrolytes have been the preferred choice so far, but affordable supplies are limited and a cheaper alternative will be needed for global scale-up, explains Nancy Stauffer at MIT who describes … [Read more...]
Electric Utilities: ESG investors should invest in, not avoid, the high-carbon emitters
Environmental, social, and governance (ESG) ratings point climate-conscious investors away from companies that are not decarbonising fast enough (or at all!). But surely they should be doing the exact opposite when it comes to climate-critical sectors like electric utilities, explain Tricia Holland, Ryan Foelske, Ella Warshauer, Jon Rea, Sarah LaMonaca and Uday Varadarajan at RMI. Of course, that presents a new challenge. The investor first needs … [Read more...]
Li-ion Grid Batteries arenât always the best replacement for Gas Peakers
Gas peakers need to be replaced with something cleaner. Like grid batteries. But the question is âwhenâ, says Maximilian Auffhammer at the Energy Institute at Haas. Summarising his co-authored paper, he explains that a review of 19 gas peakers in the U.S., replaced with Li-ion grid-scale batteries, reveals only 5 make economic and climate sense (i.e. a positive net present value after including monetised climate and human health impacts). … [Read more...]
âGreen Deal Industrial Planâ explainer: 40%+ of the top low-carbon technologies must be made in the EU by 2030
The ECâs new series of proposed targets and reforms, contained in its Green Deal Industrial Plan, aim to ensure that at least 40% of the EUâs low-carbon technologies will be made within its borders by 2030. The eight âstrategic net-zero technologiesâ are: Solar (power and thermal); Onshore and offshore wind; Batteries and energy storage; Heat pumps and geothermal; Electrolysers and fuel cells; Sustainable biogas/biomethane; CCS; Grid … [Read more...]
Analysis: U.S. IRA subsidies put two-thirds of Europeâs battery production pipeline at risk
Major battery manufacturing projects earmarked for Europe are now looking to site themselves in the U.S. to take advantage of its IRA subsidies, according to a new report by T&E. It says over two-thirds of lithium-ion battery production planned for Europe â a pipeline potential of 1.8 TWh - is now at risk of being delayed, scaled down or cancelled. The nations most at risk of losing the business are Germany, Hungary, Spain, Italy, the UK and … [Read more...]
The U.S. needs a plan to transfer electricity long distance between regions, like Europe and China
In the U.S. several hundred thousand miles of power lines connect thousands of electric generators. But whereas Europe and China, at a similar scale, have continental-scale grid development plans, the U.S. does not. Its grid is highly fragmented and consists of not one, but three separate power grids that are almost completely isolated from one another. It has twelve different transmission planning regions that must coordinate much better to cope … [Read more...]
Laser-driven Nuclear fusion achieves âignitionâ: lab gets more energy out than in
Though nuclear fusion serving the grid is surely still decades away, it has got one important step closer, explains John Pasley at the University of York. For the first time, in the U.S. the Lawrence Livermore National Laboratory achieved âignitionâ for laser driven fusion. That means more energy was taken out, by a factor of 1.5, than put in. However, the two million Joules of laser light fired at the fuel pellets needed 300 million Joules to … [Read more...]
Distribution Grid Digitalisation – benefits, policy, cost & funding
About a third of European grids are over 40 years old. A rapid physical overhaul would be impossible, so the addition of a layer of digital technologies is the key to preparing them for the distributed and intermittent generation from renewable sources, the increased electricity demand from transportation, heat pumps and other sectors, and for ensuring energy efficiency at all levels. Itâs why the EC expects about âŹ584bn of investment in Europeâs … [Read more...]
Chinaâs electricity market design should choose from successes in Europe, UK, Australia, USA
China has made substantial initial progress in its electricity market reform, but it still faces an uphill struggle in promoting the consumption of renewables, resource allocation across provinces and regions, and unlocking demand side potential. To help choose the best solutions China could do well to look at the âHandbook on Electricity Marketsâ, says Daisy Chi at ECECP. The 600-page book looks at the current state of power markets around the … [Read more...]
