Description
In order to support a buildout of renewable energy, which tends to over-generate electricity at certain times of day and under-generate at others, the grid is going to need a lot of batteries. While lithium-ion works fine for consumer electronics and even electric vehicles, battery startup EnerVenue says it developed a breakthrough technology to revolutionize stationary energy storage.

US renewable energy asset owner D E Shaw Renewable Investments (DESRI) has completed the acquisition of the Arroyo project which combines 300 MW of solar with 150 MW/600 MWh of battery energy storage, it said on Monday.
Lightsource BP – the solar developer 50% owned by the oil supermajor – announced a more than doubling in growth ambitions.
Altana AI has secured $15 million in Series A funding, led by GV (formerly Google Ventures). Floating Point, Ridgeline Partners, and existing investors Amadeus Capital Partners and Schematic Ventures joined the round, which closed in May 2021.
Today’s high energy prices could be a preview of coming attractions—a real horror movie if this winter is cold. Benchmark U.S. natural-gas prices edged above $5 per million British thermal units this month, near their highest since 2014, but they are fairly tame compared with levels in Europe and Asia. The inventory situation seems less dire at home too as underground natural-gas storage grows. The problem is that seasonal stockpiling isn’t happening quickly enough, with inventories 7.1% below their five-year average and less margin for error.
Long-duration energy storage — defined as a system that can store energy for more than 10 hours — is often called the Holy Grail of clean energy. It is the linchpin technology that will allow the economy to truly run off intermittent renewable energy sources and backup power after grid disruptions.
