ABSTRACT:
A power generation system (10) and method of operating a power generation system (10). An exemplary power generation system (10) shown in FIG.1includes a gasification system (2) for generating a supply (33) of a first gas comprising hydrogen and a supply (39) of a second gas comprising carbon monoxide based on a chemical breakdown of hydrocarbons in a melt (17). A component system (3) produces a supply of steam (99) by reacting one of the streams of gas and a steam turbine (120) generates mechanical power by expanding the steam (99). In an associated method, a melt (17) is created in a gasifier (12) which then receives a hydrocarbon source (22) to generate a continuous supply (33) of a first gas comprising hydrogen while increasing concentration of dissolved carbon in the melt (17). Hydrogen present in the first gas is supplied to a first combustor (90). A continuous supply (39) of a second gas comprising carbon monoxide is generated with carbon present in the melt (17). Carbon monoxide present in the second gas is supplied to a second combustor (80).
