Abstract
A process and/or system for producing hydrogen or fuel, fuel intermediate, and/or chemical product produced using the hydrogen. The hydrogen is produced from a feedstock containing biomethane, where the biomethane is produced from biomass. The hydrogen production includes methane reforming a feed comprising biomethane, where at least part of the reforming is conducted in one or more electrically heated reactors (e.g., direct or indirect). Carbon-containing material derived from part of the biomass not converted to hydrogen is stored as part of one or more CCS processes.
Claims26
A process of producing fuel, fuel intermediate, chemical product, or any combination thereof, the process comprising:
- providing biomethane, the biomethane produced from a biomethane production process comprising converting biomass to biomethane;
- generating hydrogen in a hydrogen production process comprising:
- (a) producing syngas in a process comprising subjecting feed comprising the biomethane provided to methane reforming, the methane reforming conducted in one or more reactors, at least one of the one or more reactors configured to provide electrically generated heat for the methane reforming, the heat for the methane reforming at least partially produced using low-carbon electricity, and,
- (b) subjecting the syngas to a purification process wherein hydrogen is separated from at least carbon dioxide, thereby producing a stream enriched in hydrogen;
- wherein carbon-containing material derived from the biomass is stored and/or used in at least one carbon capture and storage process, wherein the carbon-containing material comprises:
- (i) carbon dioxide produced from the hydrogen production process, and
- (ii) carbon dioxide produced from the biomethane production process;
- and
- wherein inputs, outputs, or a combination thereof from each of the biomethane production process, the hydrogen production process, and the at least one carbon capture and storage process are monitored, wherein each of the inputs is a material input or energy input and wherein each of the outputs is a material output or an energy output.
7-10. (canceled)
A process of producing hydrogen, the process comprising:
- providing biomethane, the biomethane produced from a biomethane production process comprising anaerobic digestion of biomass, the anaerobic digestion producing biogas and digestate, the biomethane used in a hydrogen production process comprising:
- (a) producing syngas in a process comprising subjecting a feed comprising the biomethane to methane reforming, the methane reforming conducted in one or more reactors, at least one of the one or more reactors configured to provide electrically generated heat for the methane reforming, the heat for the methane reforming at least partially produced using low-carbon electricity, and,
- (b) subjecting the syngas to a purification process wherein hydrogen is separated from at least carbon dioxide, thereby producing a stream enriched in hydrogen;
- wherein carbon-containing material derived from the biomass is stored and/or used in at least one carbon capture and storage process, wherein the carbon-containing material comprises:
- (i) carbon dioxide produced from the hydrogen production process,
- (ii) carbon dioxide from the biogas, and
- (iii) carbon-containing material produced from processing at least part of the digestate.
