ALACAES is a privately held Swiss company that is developing an advanced adiabatic compressed air energy storage (AA-CAES) solution for large-scale electricity storage.
ALACAES’ patented technology uses caverns in mountains as the pressure chamber and a proprietary thermal energy storage technology to achieve an overall round-trip storage efficiency in excess of 72% and eliminate any kind of green house gas emissions.
In 2016 ALACAES built and successfully tested the world wide first pilot plant of an advanced adiabatic compressed air energy storage technology in the Swiss Alps.
