Utility Scale Storage

H2X Global has released the first of its hydrogen-powered generators in the Australian market.

Dutch startup Elestor has secured funds to bring its hydrogen bromide (HBr) flow battery technology closer to commercial production. It said the system could achieve a levelized cost of storage below $0.05/kW.

An Iranian research group has developed a system that combines photovoltaic-thermal modules with organic Rankine cycle, a proton exchange membrane electrolyzer, and liquefied natural gas. The ideal system has an exergy efficiency of 16.24%, a cost rate of $4.48 per hour, and 33.32 kW of net electrical power.

Egypt’s hydrogen strategy is taking shape ahead of COP27 through agreements with Globeleq, Actis, and Alfanar. Elsewhere in the world, the US authorities are investing in blue hydrogen, and the city of Hamburg, Germany, has signed three agreements with Chile, Uruguay and Buenos Aires.

Massachusetts Institute of Technology researchers have developed a battery with two electrodes made of aluminum and sulfur, and a molten salt electrolyte placed between them. They said the sulfur electrodes with a high loading of 12.0 mg cm2 can sustain a high capacity of 520 mAh g–1 over 100 cycles at 5 C.

Aalborg CSP will connect a 2.5 MW ammonia heat pump to a district heating system operated by E.ON Denmark. The facility will be located at a local wastewater treatment plant.

Toshiba has developed a smart synchronous inverter that stabilizes power fluctuations in microgrids. The Japanese company said it has tested the device in combination with PV and battery storage.

Renewable energy investors have proposed more than 40 new clean energy projects, or about 17 GW of capacity, for a coordinated “renewable energy zone” to be built in New South Wales, Australia.

JSW Energy, a private-sector power producer, will set up 1 GWh of standalone, grid-connected battery energy storage projects on a build-own-operate-transfer basis in the Indian state of Rajasthan.

Hydrostor has selected an engineering company to provide front-end studies for a 500 MW compressed air energy storage project in California.
