摘要
电转气技术(power to gas,P2G)是实现中国可再生能源大规模消纳的潜在方案,其核心电解技术按照工作温度可划分为低温与高温电解两类,其中高温电解电池具有转换效率高、转换产物丰富以及支持可逆运行等优势,是未来能源与电力系统中极具吸引力的规模化储能技术。文章主要从电池结构、转换模式、系统接入等方面介绍高温电解技术的特点及其在电力储能中的潜在应用。电池结构方面,新兴的扁管式结构兼具了板式与管式的结构优点;转换模式方面,高温电解池可单独制取H2或CO,也可共电解直接合成CH4;系统接入方面,可采用纯电电解接入、余热辅助电解接入、可逆的储气发电接入等多种模式,从而在高效消纳可再生能源的同时提供丰富的灵活性资源。在能源互联网建设的大背景下,高温电解技术在大规模储能方面的应用指日可待。
