Transnistria's storage systems combine lithium-ion batteries with something you wouldn't expect - repurposed electric vehicle (EV) batteries from Western Europe. Wait, no. actually, they're using new LiFePO4 (lithium iron phosphate) cells specifically designed for stationary storage.
[pdf] Among the most scalable and innovative solutions are containerized solar battery storage units, which integrate power generation, storage, and management into a single, ready-to-deploy package.
[pdf] These modular units store excess solar heat in ceramic bricks at 1,500°C - four times cheaper than battery arrays for overnight power generation. A pilot project at Ouaga 2000 Industrial Zone achieved 94% efficiency in converting stored heat to electricity.
[pdf] Construction of the Guishan Offshore Windfarm began in September 2016 by the facility's owner, Southern Offshore Wind Power Joint Development shortly after the approval of the project by the Guangdong Development & Reform Commission. By March 2018, the wind farm is already 75 percent complete and the facility already began generating electricity on March 13, 2018.
[pdf] Compression of air creates heat; the air is warmer after compression. Expansion removes heat. If no extra heat is added, the air will be much colder after expansion. If the heat generated during compression can be stored and used during expansion, then the efficiency of the storage improves considerably. There are several ways in which a CAES system can deal with heat. Air storage can be , diabatic, , or near-isothermal.
[pdf] Estonia Unveils Baltic’s Largest Solar Park, Powering 35,000 HomesEstonia launched the Baltic States’ largest solar park, Kirikmäe, with a 77.53 MW capacity to power 35,000 households.Evecon and Mirova collaborated on the project, adding over 100 MW of new solar capacity to Estonia’s grid in one week.Estonia aims to meet 100% of its electricity needs with renewable energy by 2030, with solar as a key driver.
