“储能已成为人类有效利用能源最后一公里。”储能不仅可以提高常规发电和输电的效率、安全性和经济性,也是实现可再生能源平滑波动、调峰调频,满足可再生能源大规模接入的重要手段,同时也是分布式能源系统、电动汽车产业的重要组成部分,在能源互联网中具有举足轻重的地位。迄今为止,储能技术在世界范围内已有许多实际工程和示范应用。围绕“低成本、长寿命、高安全、易回收”的研发应用目标,各类新型储能技术的研究和开发正在如火如荼地进行。 “Energy storage has become the last mile for humans to use energy efficiently.” “Energy storage can not only improve the efficiency, safety, and economics of conventional power generation and transmission, but also achieve smooth fluctuations in renewable energy sources, peaking and frequency regulation, and meeting renewable energy sources.” The important means of large-scale access is also an important part of the distributed energy system and electric vehicle industry, and plays a decisive role in the energy Internet. To date, there are many practical engineering and demonstration applications of energy storage technology worldwide. Around the goal of R&D and application of “low cost, long life, high security, and easy recovery,” research and development of various new types of energy storage technologies are in full swing.
