摘要

With the worsening of energy shortage and environmental pollution,energy storage has received much attention in the fields of renewable and sustainable energy in recent years.It is widely known that energy storage is a technique storing excess energy in one form and converting it back to the same form or another when necessary [1].Especially energy storage occupies an important position in solar energy,wind energy and ocean energy.Generally,energy storage methods include mechanical energy storage,electrical energy storage and thermal energy storage (TES) [2].Due to the use of natural resources,mechanical energy storage has advantages of environmental protection,large scale,long life cycle and low operation costs.And electrical energy storage has advantages in some areas like convenient application,low pollution and high conversion efficiency.Mechanical energy storage usually can be subdivided into pumped-hydro energy storage,compressed air energy storage,flywheel energy storage,etc.Electrical energy storage can be divided into battery energy storage,flow battery energy storage,superconducting magnetic energy storage and super capacitor energy storage,etc.In the face of various energy storage technologies,how will thermal energy storage accelerate its development and application?
