Compressed Air Energy Storage

Landis Energy is the operator of the Alton Natural Gas Storage project currently being developed near Truro, Nova Scotia and the Maritimes and Northeast Pipeline. The proposed underground storage facility will be capable of storing natural gas and other hydrocarbons. It is expected that Alton will serve customers seeking to manage their supply requirements in eastern Canada and the United States. Currently, there are no underground natural gas storage facilities north of Boston along the Maritimes and Northeast Pipeline route, which runs from Nova Scotia to the northeast United States.

Compressed Air Energy Storage (CAES) systems use excess power from sources such as wind farms, tidal farms, solar energy, coal plants and nuclear plants. This excess power is removed from a grid and used to run an electric motor driven air compressor. The air compressor pressurizes air into an underground reservoir such as a salt cavern. When power is needed, it is produced by returning the compressed air to the surface, heating it and combusting with natural gas and then expanded through turbines to run a generator. The generator creates electricity that is delivered back onto the grid in order to meet peak demand.
