Title - Saskatchewan's Energy Storage Advantage: Compressed Air Energy Storage in Salt Caverns
We have abundant wind and solar resources in Saskatchewan but including these power sources in our energy-supply mix is challenging because they are intermittent. To smooth this generation to provide “firm capacity”, with the same reliability as a natural gas generating facility, utility-scale energy storage is required. This naturally leads us to consider using batteries that are charged when the sun is shining or the wind is blowing, then discharged when these renewable sources are not available. In Saskatchewan, there is a better, and potentially cheaper, solution than building fleets of chemical batteries. Because of our geological advantage, we can couple Compressed Air Energy Storage (CAES) technology with rock-salt caverns in the deep subsurface, where electricity generated from renewable sources is used to compress and store atmospheric air. Using solar generation, for example, the cavern is charged while the sun is shining, then, at night-time, this compressed air is controllably released into an electricity-generating turbine. Since the 1950s, we have successfully mined and operated salt caverns to store natural gas and other hydrocarbons and this experience can be applied directly to the development and operation of salt caverns for air storage. Significant investments must be made to replace retiring coal generation by 2030 and to meet future increases in demand. CAES is a simple, reliable, and proven technology that has been used in Germany since 1978 and in the USA since 1991. The technology is safe, cost effective and it produces no toxic waste.

has provided geological consulting services to the petroleum and potash industries in Saskatchewan since 1985, including the assessment of deep saline aquifers for the mining of geothermal heat to be used in direct heating applications. Since 2019, investigations include the potential integration of Compressed Air Energy Storage (CAES) technology within Saskatchewan’s geological and power generation infrastructure.
