Fuel production system includes: synthesis gas generation unit configured to generate synthesis gas containing hydrogen and carbon monoxide from carbon-containing raw material; fuel production unit configured to produce fuel from synthesis gas generated; water electrolyzer configured to electrolyze water to generate water-electrolyzed hydrogen; hydrogen supply unit configured to supply water-electrolyzed hydrogen generated to synthesis gas generation unit; and controller. The controller is configured to perform: calculating input energy based on first energy possessed by raw material, second energy consumed by water electrolyzer, third energy consumed by synthesis gas generation unit, and fourth energy consumed by fuel production unit; calculating recovered energy based on fifth energy possessed by fuel produced; and determining supply amount of water-electrolyzed hydrogen to be supplied based on input energy and recovered energy calculated.

Embodiments include a method for converting renewable energy source electricity and a hydrocarbon feedstock into a liquid fuel by providing a source of renewable electrical energy in communication with a synthesis gas generation unit and an air separation unit. Oxygen from the air separation unit and a hydrocarbon feedstock is provided to the synthesis gas generation unit, thereby causing partial oxidation reactions in the synthesis gas generation unit in a process that converts the hydrocarbon feedstock into synthesis gas. The synthesis gas is then converted into a liquid fuel.

A process for the manufacture of one or more useful products comprises: gasifying a carbonaceous feedstock comprising waste materials and/or biomass in a gasification zone to generate a raw synthesis gas; supplying at least a portion of the raw synthesis gas to a clean-up zone to remove contaminants and provide a clean synthesis gas; supplying the clean synthesis gas to a first further reaction train to generate at least one first useful product and a tailgas; and diverting selectively on demand a portion of at least one of the carbonaceous feedstock, the clean synthesis gas, the tailgas and the light gas fraction to heat or power generation within the process, in response to external factors to control the carbon intensity of the overall process and enable GHG emission savings.

The invention relates to a process and system for converting carbon material into power. Carbon material 12 is gasified into synthesis gas 18 in a gasifier 16, and steam 14 is supplied to the gasifier 16. The synthesis gas 18 is supplied to a gas turbine 30, 36, 38 to produce power. Air 24 is added to the synthesis gas 18 prior to the gas turbine 30, 36, 38. Exhaust gas 40 from the gas turbine 30, 36, 38 is cooled in a first cooling device 42 with water 46 to produce steam 52. The steam is used in at least one steam turbine to produce power 56 and the steam 58 from at least one steam turbine 56 is recycled to the gasifier 16.
