Geological compressed air energy storage as an enabling technology for renewable energy in Ontario, Canada

Abstract

As renewable resources are increasingly used to provide power to the world’s demand centres, dealing with the intermittent nature of these resources and their affect on the power grid is becoming a significant issue. Compressed air energy storage (CAES) is one technology that is proposed to increase flexibility when integrating renewable energy sources such as wind, solar and tidal generation with the power grid. By creating a storage medium where the energy produced from these sources can be stored and dispatched to the grid as required, a higher penetration of renewable energy generation can be achieved.
