Australia’s first compressed air energy storage facility

South Australia’s impressive range of renewable energy projects is set to increase with the news that a Canadian company has received development approval to build a $30 million advanced compressed air energy storage (A-CAES) facility at the Angas Zinc Mine near Strathalbyn.

The Angas A-CAES facility is the first of its kind in Australia and will use excess electricity from wind and solar to run a compressor and produce heated, compressed air that can be stored underground. The compressed air is released to drive a generator and produce electricity when demand in the electricity grid is high.

Hydrostor will re-purpose the former Angas Zinc Mine at Strathalbyn into the 5MW / 10MWh facility by transforming the existing mine into an air-storage cavern 240 metres below ground using their innovative design to achieve emissions free energy storage.

The $30 million project is supported by $3 million in funding through the South Australian Government’s Renewable Technology Fund and $6 million in funding from the Australian Renewable Energy Agency (ARENA).

Hydrostor is expecting around 40 jobs during the construction phase and a further four ongoing positions over the project’s 30 year lifespan.
