新型储能发展分析及其经济性评估研究

Development analysis and economic evaluation of new energy storage

为研究在新型电力系统中新型储能技术对项目经济性的影响,采用财务经济评价方法,对抽水蓄能、锂离子电池、压缩空气、钒液流电池、铅炭电池等5类储能进行经济性评估及应用前景分析。结果表明:在碳达峰、碳中和目标下,储能需求空间广阔,根据经济性评估,由大到小依次排序为抽水蓄能、压缩空气储能、锂离子电池储能、铅炭电池储能与钒液流电池储能,其他新型储能路线也进入了发展快车道。在市场需求爆发以及政策鼓励的双重推动下,新型储能技术加速迭代,有望通过技术进步实现能效提升以及成本下降。

In order to study the impact of Advanced Energy Storage Technologies on the economic performance of project in a new power system,five types of energy storage,pumped storage,lithium-ion batteries,compressed air,vanadium liquid flow batteries and lead-carbon batteries were evaluated economically and analyzed with financial and economic evaluation methods.The results show that under the carbon peak,carbon neutralization and target,there is a wide space for energy storage.In view of the economic evaluation,the order is pumped storage,compressed air storage,lithium ion battery storage,lead-carbon battery storage and vanadium liquid flow battery storage.Other new energy storage routes have entered the development fast lane.The results showed that driven by both market demand outbreak and policy encouragement,the new component technology accelerates iteration,and is expected to rapidly achieve the energy efficiency improvement and cost reduction through technological progress,and enter the fast lane of development.
