General Electric switches on 1.2 GW pumped hydro facility in China
General Electric has switched on two more 300 MW pumped storage turbines at a 1.2 GW hydro battery complex in China’s Anhui province, after finalizing the facility’s first 600 MW unit in December. The project has completed a trial period and commercial operations are now fully underway.
Swiss manufacturer unveils mini batteries for balcony solar panels
Soleis AG has developed two storage systems with capacities of 1 KWh and 2 kWh.
Only5mins! – PV system prices could drop by around 10% in Europe in 2023
Andreas Thorsheim, the CEO of Norway-based residential solar specialist Otovo, speaks to pv magazine about solar array prices, current market trends for distributed storage, and shortages of qualified professionals.
The Hydrogen Stream: World’s largest hydrogen airplane makes first flight
ZeroAvia tested its new 19-seat hydrogen-powered aircraft, Chinese scientists unveiled new tech to promote bubble removal in electrolyzers, and Egypt-Japan University of Science and Technology researchers claimed that the most efficient hydrogen production systems are based on waste heat.
Retired coal sites to host multi-day iron-air batteries
Form Energy will install two 10 MW / 1,000 MWh batteries on the sites of Xcel Energy’s former coal-fired plants.
Australian scientists unveil method to produce hydrogen straight from ocean
University of Adelaide researchers and their international partners have successfully used seawater with no pre-treatment to produce green hydrogen. They did this by introducing an acid layer over the catalysts in situ.
US developer moves toward licensing for 900 MW pumped storage project
Developer rPlus Hydro has submitted an application for a final license to the US Federal Energy Regulatory Commission for the Seminoe project– a milestone reached by only a few pumped storage projects over the last 20 years.
Second-life batteries might beat new ones on solar LCOE in remote locations
UK scientists have discovered that second-life batteries could provide a lower levelized cost of electricity (LCOE) than conventional batteries in school buildings equipped with PV in East African schools. They said the cheapest system configuration uses either 7.5 kW or 10 kW of solar with 20 kWh of storage.
Only5mins! – ‘Additionality’ must be adhered to in Africa’s green hydrogen development
Chigozie Nweke-Eze is an economist, geographer and founder of Integrated Africa Power. He sat down with pv magazine to discuss green hydrogen development in Africa, from the project pipeline to the necessity of “additionality” when it comes to ensuring hydrogen doesn’t become yet another exploited African resource.
Australian scientists source silicon from solar waste to build better batteries
Researchers from Victoria’s Deakin University say they have successfully tested a new process that can safely and effectively extract silicon from end-of-life solar panels, and then convert it into nano materials worth more than $45,000 (USD 31,500) per kilogram, in order to build better batteries.
