摘要：Electricity storage devices can be divided into indirect storage technology devices (involving electricity conversion into another form of energy),and direct storage (in an electric or magnetic field).Electricity storage technologies include: pumped-storage power plants,BES Battery Energy Storage,CAES Compressed Air Energy Storage,Supercapacitors,FES Flywheel Energy Storage,SMES Superconducting Magnetic Energy Storage,FC Fuel Cells reverse or operated in systems with electrolysers and hydrogen storage.These technologies have different technical characteristics and economic parameters that determine their usability.This paper presents two concepts of an electricity storage tank with a storage capacity of at least 50 MWh,using the BES battery energy storage and CAES compressed air energy storage technologies.
