With the rapid development of China's electric power industry ,the renewable energy ,e.g.,wind andsolar energy,has rapidly   developed.However,the uneven spatial distribution and the supply instability greatlrestrict the development of new energy technologies. Focused on the development of gravity energy storage( CES) technologies ,it introduces four kinds of new grid-level gravity energy storage technologies emerging inthe world in recent years,including Gravity Power CES in USA,Ares Mountain GES in USA, Energy VaultCES in Swiss ,and Gravitricity CES in UK.Compared to the traditional electrochemical energy storage methodsuck kinds of CES technologies has the advantages of safety , large storage capacity and small impact on theenvironment.Also,they significantly reduce the dependence on geographical conditions and water resources.which are beyond the application of the traditional pumped hydro storage CES method.Thus , these new CESmethods have broad application prospects. According to the available researches, it also points out thedevelopment obstacles and technical problems of the new gravity energy storage technology ,which can providespecific guidance on the domestic development of GES technologies in China.
