A study by eStorage, a European Commission-funded consortium based in Switzerland, covers the EU-15, Norway and Switzerland. It demonstrates huge potential for energy storage in European countries, which can be unlocked by using pumped hydro energy storage plants. The researchers were focusing on water reservoirs that already exist in the countries and can be used for pumped hydro energy storage. By transferring water between two reservoirs at different elevations, these facilities can deliver electricity when the system needs it and store electricity generated by wind and solar plants. Using existing reservoirs, instead of building new ones, developers can lower costs and shorten the time ...Den vollständigen Artikel lesen ...
