The present invention relates to a gas turbine power generation system, that includes a hydrogen-cooled generator having hydrogen as coolant, a plant hydrogen storage, generator auxiliaries and an emergency power supply system. The power generation system includes a fuel cell using hydrogen as fuel.
The present invention relates to a gas turbine power generation system, that includes a hydrogen-cooled generator having hydrogen as coolant, a plant hydrogen storage, generator auxiliaries and an emergency power supply system. The power generation system includes a fuel cell using hydrogen as fuel. The fuel cell is supplied via a line with hydrogen fuel from the hydrogen filling of the hydrogen-cooled generator in case of failure or disruption of the power supply from the gas turbine power generation system. In a preferred embodiment the fuel cell is supplied with additional hydrogen via a line from the plant hydrogen storage and/or with additional hydrogen via a line from generator auxiliaries in case of failure or disruption of the power supply from the gas turbine power generation system.
