关闭/废弃矿井地下空间抽水蓄能发展战略研究

Development strategy of pumped storage in underground space of closed/abandoned mines

在双碳战略目标牵引下,中国深化能源革命,目前已成为世界上最大的可再生能源发电国。为解决大规模可再生能源电力供应不稳定的难题,新型电力系统的提出与加速成长促进了抽水蓄能电站的建设与发展,但在生态红线与地形等因素约束下,传统抽水蓄能电站选址难题亟须解决。同时,煤炭去产能过程中形成了大量的关闭/废弃矿井与资源枯竭型城市。本研究详细概述了中国抽水蓄能电站的发展现状,分析了关闭/废弃矿井与抽水蓄能结合后对水资源压力的缓解与温室气体减排等环境效益。基于关闭/废弃矿井抽水蓄能电站不同模式,对关闭/废弃矿井抽水蓄能应用潜力展开了分析,最后提出中国废弃矿井抽水蓄能发展战略,并展望了关闭/废弃矿井+储能的多元产业愿景。

To achieve carbon peaking and carbon neutrality,China has deepened its energy revolution with the largest renewable energy power generation capacity in the world.In face of the unstable power supply of large-scale renewable energy,a new power system has been proposed and constantly upgraded,which promoted the construction and development of pumped storage power station.Under terrain constraints and the ecological red line,the site selection of traditional pumped storage power station is a hard nut to crack.At the same time,a large number of closed/abandoned mines and resource exhausted cities emerged in the process of coal capacity reduction.This study gave a detailed overview of the status quo of pumped storage power station in China,and analyzed the environmental benefits of the combination of closed/abandoned mines and pumped storage,such as water resource pressure relief and greenhouse gas emission reduction.Based on the different modes of closed/abandoned mine pumped storage power stations,this study analyzed the application potential of closed/abandoned mine pumped storage.Finally,this paper proposed the development strategy of China􀆳s abandoned mine pumped storage,and the prospects of closed/abandoned mine+energy storage in multiple industries.
