1. A power plant configured to output power to a grid power system, comprising:
a hydrogen generation system configured to produce hydrogen, wherein the hydrogen generation system comprises an electrolyzer;
a gas turbine combined cycle power plant comprising:
a gas turbine engine configured to combust hydrogen from the hydrogen generation 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 hydrogen generation system;
a heat exchange circuit connected to the electrolyzer to cool or heat the electrolyzer, wherein the heat exchange circuit is connected to the gas turbine combined cycle power plant and is provided with steam; and
a controller configured to:
operate the hydrogen generation system with electricity from the grid power system when the grid power system has excess energy; and
balance active and reactive loads on the grid power system using at least one of the hydrogen generation system and the gas turbine combined cycle power plant.
