储能技术研发、应用的现状与前景

Abstract:Currently pumped hydroelectric storage dominates in terms of installed capacity in global operational energy storage projects，electrochemical energy storage dominates in terms of numbers of projects. Pumped hydroelectric storage is mature in technology and its application potential depends on governmental policy. There are many different specific technologies of electrochemical energy storage in competition. Li-ion batteries are gaining great application potential in energy storage systems since its cost declines quickly due to its massive application in electric cars. Traditional lead-acid battery also gets its market share in the energy storage industry. China needs to build its recycle system of lead-acid batteries to better deal with the pollution. Mass deployment of advanced battery technologies like Sodium Sulphur battery，ZEBRA battery and flow batteries is up to economic attractiveness，while other advanced energy storage technologies are still on the stage of research and development.
