Southwest Research Institute (SwRI) has commissioned a first-of-its-kind pilot plant pumped heat energy storage demonstration facility with tech from US startup Malta. Its 10-150+ hour energy storage technology is said to be applicable in a range of grid-scale applications. September 5, 2022 Marija MaischIn a key milestone for its pumped-heat energy storage (PHES) technology, Malta Inc., a startup spun out of Google X, has announced that Southwest Research Institute (SwRI) has completed assembly and commissioning of a first-of-a-kind PHES demonstration facility.Malta’s system stores electricity either directly from a power plant or from the grid. It does this by converting electricity into thermal energy (heat and cold). The heat is stored in molten salt, a proven method of storing thermal energy, and the cold is stored in an antifreeze-like solution with components and subsystems…
