An energy storage system includes a combustion turbine configured to output a heated purge gas; a reformer configured to receive the natural gas and output reformed natural gas; a molten carbonate electrolytic cell (MCEC) comprising an MCEC anode and an MCEC cathode, where the MCEC is configured to operate in a hydrogen production mode in which the MCEC anode receives the reformed natural gas from the reformer and outputs an MCEC anode exhaust gas containing hydrogen and the MCEC cathode is configured to receive the heated purge gas from the combustion turbine and outputs an MCEC cathode exhaust gas; and a storage tank configured to receive MCEC anode exhaust gas containing hydrogen. 一种能量储存系统包括：燃烧式涡轮机，配置为输出加热的吹扫气体；重整器，配置为接收天然气并输出重整天然气；熔融碳酸盐电解池(MCEC)，包含MCEC阳极和MCEC阴极，其中MCEC配置为在制氢模式下运行，在制氢模式下，MCEC阳极接收来自重整器的重整天然气，并输出含有氢气的MCEC阳极排气，并且MCEC阴极配置为接收来自燃烧式涡轮机的加热的吹扫气体，并输出MCEC阴极排气；以及储罐，配置为接收含有氢气的MCEC阳极排气。
