Zinc mine to be converted to compressed air energy storage

Australia’s first energy storage project using compressed air, which will repurpose the Adelaide Angas Zinc Mine, has received $6 million in funding from The Australian Renewable Energy Agency (ARENA) and $33.3 million for the South Australian Government.

Hydrostor will construct the 5MW/10MWh fuel-free Advanced Compressed Air Energy Storage (A-CAES) facility.

The $30 million commercial demonstration project will use the existing mine to develop a below-ground air-storage cavern that uses an innovative design to achieve emissions free energy storage. The facility will provide synchronous inertia, load shifting, frequency regulation and support for grid security and reliability.
