Abstract. A flywheel energy storage (FES) system is an electricity storage technology under the category of mechanical energy storage (MES) systems that is most appropriate for small- and medium-scale uses and shorter period applications. In an FES system, the surplus electricity is stored in a high rotational velocity disk-shaped flywheel.
DOE Long Duration Earth Shot Goal. THEMES Impact. The DOE is aiming to reduce energy storage costs by 90% to achieve an LCOS of $0.05/kWh in storage systems with 10+ hours of duration, all in the next 10 years. THEMES subsurface solutions allow for the reduction in cost that thermal and mechanical storage solutions need.
As of 2018, the energy storage system is still gradually increasing, with a total installed grid capacity of 175 823 MW [ 30 ]. The pumped hydro storage systems were 169557 GW, and this was nearly 96% of the installed energy storage capacity worldwide. All others combined increased approximately by 4%.
