Due to the intermittent feature of renewable energies, their combination with energy storage systems seems efficient and profitable. In this regard, a wind turbine system is coupled with a compressed CO 2 energy storage (CCES) system for multi-generation propose. This combination has not been done yet and seems very attractive and efficient

Australia''s Clean Energy Council has joined calls for the country to adopt a deployment target for energy storage, while arguing that a proposed capacity mechanism plan be scrapped. The national Energy Security Board (ESB) published a draft high-level design proposal for a capacity mechanism earlier this
