Energinet has now been authorised to make its underground storage facilities available to commercial actors seeking to store compressed air. The intention is for compressed air energy storage to contribute to a more flexible and resilient Danish electricity system. Ørsted has taken the next big step. Ørsted is now commencing the construction of two CO2 capture facilities (CCS) designed to capture and store CO2 emissions from the wood chip-fired Asnæs Power Station in Kalundborg and the straw-fired facility at Avedøre Power Station in Hvidovre. This project represents Denmark's first full-scale.

What is a compressed air energy storage station? "The compressed-air energy storage station offers large capacity, long storage time (over 4 hours), and efficient response, making it comparable to small and medium-sized pumped storage power plants," Liu Yong, Secretary General of Energy Storage. Thermal mechanical long-term storage is an innovative energy storage technology that utilizes thermodynamics to store electrical energy as thermal energy for extended periods.
