Energy Storage

Rapidly deploying 5.2 GW of planned solar and storage in Puerto Rico, a possibility raised in a report by six national laboratories, would require an improvement in the Puerto Rico utility’s practices. A mandated procurement process has suffered delays at many steps.

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.

Turkey has released a hydrogen roadmap as part of its plans to meet its 2035 net-zero emission targets, hinging on solar energy and importing electrolysis technologies in the short term. Gulmira Rzayeva, research fellow at the Oxford Institute for Energy Studies, says this target is realistic.

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.

Scientists in Austria have developed a long-term energy storage system that uses regenerative braking to adjust the descent speed of sand in mine shafts and generate electricity.

US-based Salgenx has developed a scalable redox flow battery with two separate tanks of electrolytes, one of which is saltwater. Unlike other flow batteries, the new device is membrane-free, promising big gains at the levelized cost of storage level.

The World Future Energy Summit showed that Middle Eastern solar markets are still driven by utility-scale PV, although the C&I sector shows signs of growth. Saudi Arabia, Egypt and the United Arab Emirates are the most promising markets for big solar projects, with huge pipelines under development, while Lebanon and Yemen show promise due to chronic energy shortages.
