新たな断熱圧縮空気蓄電システム『空圧電池_®』の開発

抄録

　We have been developing new Compressed Air Energy Storage System which is trademarked as ”CAB”. The CAB -Compressed Air Battery- is the machine type battery which is expected to be used for short-time load leveling in the grid-connected operation of wind-farm and mega-solar power generation, and for peak cutting of power demands for factories and buildings. By using screw type compressors and turbines, it can be possible to follow frequent load leveling against renewable energy compared with turbo and reciprocating machineries that have difficulties in part load operation or rapid change of speed. The features of CAB system, equipment configuration, system efficiency, and characteristics of charging/discharging are mainly introduced in this paper as clean power energy storage system used compressed air.
