Hydrostor Australia is deploying Advanced Compressed Air Energy Storage (A-CAES) and will construct a 5 MW / 10 MWh fuel-free facility that stores compressed air in a below-ground cavern repurposed from the Angas Zinc Mine. The system uses grid electricity to compress air, captures and stores heat during charging, and reheats released air to drive a turbine on discharge. The facility is designed to provide synchronous inertia, load shifting, frequency regulation and other grid-security services while remaining emissions-free. The $30 million commercial demonstration project is sited at Strathalbyn, 60 kilometres southeast of Adelaide, converting a brownfield mine into a clean-energy hub. Hydrostor received $6 million in funding from ARENA and $3 million from the South Australian Government toward the demonstration. The company positions A-CAES as a dispatchable, fuel-free complement to pumped hydro with flexible siting advantages.
