Energy Storage

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.

Form Energy will install two 10 MW / 1,000 MWh batteries on the sites of Xcel Energy’s former coal-fired plants.

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.

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.

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.

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.

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.

Chanda Nxumalo, the chairperson of the South African Photovoltaic Industry Association (SAPVIA), speaks with pv magazine about the prospects of the South African energy market, its new regulations and the bright future for the PV sector. Nxumalo also addresses the challenges and opportunities for battery storage, green hydrogen and women in renewables.

Energiasalv has secured a construction permit to build a 6 GWh pumped hydro storage plant in Paldiski. Work on the facility is planned to start in the summer of 2024.

Two of Australia’s richest people are expected to be rivals in the bidding process for Sun Cable, the developer of what could be the world’s biggest intercontinental solar and energy storage project. Administrators indicate that the sale process could be completed within three months.
