Abstract
An apparatus for storing energy includes a compression chamber for receiving a gas, a compression piston for compressing gas contained in the compression chamber, a first heat store for receiving and storing thermal energy from gas compressed by the compression piston, an expansion chamber for receiving gas after exposure to the first heat store, an expansion piston for expanding gas received in the expansion chamber, and a second heat store for transferring thermal energy to gas expanded by the expansion piston. The cycle used by the apparatus has two different stages that can be split into separate devices or combined into one device.
