A 100kW/1.5MWh zinc-air battery will be installed in Queens, New York, in combination with a combined heat and power system and a PV array. The pilot project is intended to demonstrate the long-duration energy storage capability of the zinc-air battery.

Philip Shen, managing director of ROTH Capital Partners, hosted top analysts from PV InfoLink to discuss their outlook on pricing, supply and demand at each step in the solar value chain.

Nitricity has developed an experimental plasma reactor that uses PV electricity to produce competitively priced, environmentally clean, nitrogen fertiliser. Its onsite fertiliser production eliminates emissions from transport, and provides a viable alternative to fossil-based nitrogen fixation methods like the Haber-Bosch process.

Electric vehicle giant Tesla has inked an offtake deal with Australian miner Syrah Resources to supply battery-ready graphite as concerns over raw materials shortages continue.

The supply of indium, both for layers in silicon solar cells and some thin-film PV technologies, is increasingly seen as a future potential bottleneck that solar and other industries relying on the material will have to manage. Resolving indium supply concerns may be a case of rethinking mining waste and recycling, reports Ian Morse.

Western Australian solar window company ClearVue says it has proven its products can reduce buildings’ carbon emissions by as much as 90%, qualifying the technology for the world’s most comprehensive future building standards for energy performance.

Scientists in the United States have proposed to use a thermochemical energy storage (TCES) technique that stores energy in chemical bonds to recover the heat produced during air compression operations. According to them, this innovation may increase the round-trip efficiency of compressed air energy storage to 60%.

Current price signals to distributed battery owners “do not align with grid value,” says a study from the Lawrence Berkeley Laboratory.

A new underwater battery storage technology is coming from Netherlands-based Ocean Grazer to address the issue of offshore long-duration storage. The company’s Ocean Battery is touted as innovative yet simple, based on existing technology, and capable of enhancing marine life along the way.

The investment is planned to support development and construction of Hydrostor’s 1.1GW, 8.7GWh of Advanced Compressed Air Energy Storage projects that are well underway in California and Australia, and help expand Hydrostor’s project development pipeline globally.
