1. Hydrogen-fuelled gas turbine power system with pre-combustion CO2 capture, the main parts of which being comprised by a compressor (22), a combustor (24) and a turbine (26) as well as a fuel supply (10),
the turbine (26) being adapted for connection to an electrical energy power generator;
the fuel supply (10) comprising a hydrogen gas producing reactor system with at least one reactor (12) comprising i) a reactor capable of supporting sorption enhanced steam methane reforming of methane, ii) a reactor capable of supporting sorption enhanced water gas shift of syngas, or a combination thereof; and
the reactor (12) being connected in a closed loop with a regenerator (14) for circulating and regenerating a CO2 absorber between the reactor (12) and the regenerator (14), characterized in the presence of a closed heat exchange loop (21) between the regenerator (14) of the hydrogen gas producing reactor system (10) and at least one of the downstream end of the combustor (24) of the hydrogen-fuelled gas turbine (20) or the upstream end of the turbine (26) of said hydrogen-fuelled gas turbine, to thereby raise the temperature in the regenerator (14) while simultaneously lowering the temperature in the upstream end of the turbine (26) of the hydrogen-fuelled gas turbine (20) and cooling relevant parts of the hydrogen-fuelled gas (20) to a level acceptable for long term stable use of the hydrogen-fuelled gas turbine.
