By Dan Gearino

This compressed air energy storage plant in Goderich, Ontario, is one of the two small plants built by Hydrostor ahead of its current proposals to build much larger plants in California. The Goderich plant, completed in 2019, can discharge 1.75 megawatts for about six hours before needing to be recharged. Photo Courtesy of Hydrostor
