电力低碳转型背景下氢储能的挑战与展望

Challenges and Prospects of Hydrogen Energy Storage Under the Background of Low-carbon Transformation of Power Industry

随着新能源占比逐渐提高,作为辅助新能源并网的储能技术受到广泛关注。氢储能和燃料电池技术已被我国列为战略性能源技术,并积极应用到市场和企业发展中。电解水制氢可以平抑可再生能源并网带来的波动,帮助电网削峰调频;燃料电池作为提高能源转换率的发电装置,同时具备噪音小、无污染等优势,是消纳可再生能源的有效方式之一。对现有储能技术的发展现状和优势进行对比分析,着重介绍了氢储能系统目前关键技术和研究方向,并对氢储能商业化发展进行展望。

With the gradual increase in the proportion of new energy,energy storage technology,as an auxiliary new energy grid,has attracted wide attention.Hydrogen energy storage and fuel cell technology have been listed as strategic energy technologies in China,and have been actively applied in the market and enterprise development.Hydrogen production from electrolytic water can stabilize the fluctuation caused by the connection of renewable energy to the grid and help the power grid to cut peak and frequency modulation.As a power generation device to improve energy conversion rate,fuel cell has the advantages of low noise and no pollution,it is one of the effective ways to absorb renewable energy.This paper made a comparative analysis of the development status and advantages of the existing energy storage technologies,the key technologies and research directions of hydrogen energy storage system were introduced emphatically,and the commercial development of hydrogen energy storage was prospected.
