Utility Scale Storage

Renewables developer GMR Energy has started working on a 240 MW/480 MWh battery project in Victoria, Australia.

US scientists have looked at how aquifer thermal energy storage (ATES) could be used to store wind and solar power, while catering to heating and cooling energy demand during extreme hot or cold periods. They modeled a distributed energy system for a neighborhood in Chicago and found that ATES could reduce consumption of petroleum products by up to 40% at a slightly higher cost than other forms of storage.

H2FLY has wrapped up initial filling tests with the liquid hydrogen tank for its HY4 aircraft, while Wingcopter has announced the development of a hydrogen-fed delivery drone.

The US National Renewable Energy Laboratory (NREL) has unveiled a tool that surveys how changes in costs, battery adoption scenarios, and international actions affect long-term trends in the battery supply chain.

Tesla has revealed plans to build a new Megapack battery factory in Shanghai, according to the Xinhua news agency.

Israeli company Brenmiller is set to launch a 4 GW to 5 GW production line for its thermal energy storage systems, which use crushed rocks to retain heat that can be released as steam, hot water, or hot air.

Eight industrial and scientific entities in Germany have come together to pursue two key innovations in lithium-ion battery technology: the replacement of metal foils with a metallized fabric structure, and the use of silicon as anode material.

Scientists in Italy have looked at how flywheel storage and reversible solid oxide cells could be integrated with lithium-ion batteries in minigrids powered by solar. They found that flywheels combined with batteries could be the cheapest option for power smoothing.

Sun Cable’s troubled AUD 30 billion ($20 billion) mega solar and storage project has received a welcome boost, with resources company Tivan announcing that it has signed a deal with the developer for the potential offtake of up to 300 MW of renewable electricity.

EirGrid assigned 7.2 GW of capacity in its latest auction, with 5.4 GW to come from gas power plants. The auction clearing price reached €83.050 ($90.554)/MW per year.
