1. A power plant configured to output power to a grid power system, comprising:
an electrolyzer system configured to produce hydrogen;
a gas turbine combined cycle power plant comprising:
a gas turbine engine configured to combust hydrogen from the electrolyzer system to generate a gas stream that can be used to rotate a turbine shaft; and
a heat recovery steam generator (HRSG) configured to generate steam with the gas stream of the gas turbine engine to rotate a steam turbine;
a storage system configured to store hydrogen produced by the electrolyzer system; and
a heat exchange circuit connecting the electrolyzer system and the HRSG, the heat exchange circuit configured to circulate at least one of steam and water between the HRSG and the electrolyzer system to heat the electrolyzer system;
wherein the heat exchange circuit extends between individual electrolyzers of the electrolyzer system.
