Abstract
A process and/or system for producing fuel using renewable hydrogen having a reduced carbon intensity. The renewable hydrogen is produced in a hydrogen production process comprising methane reforming, wherein at least a portion of the feedstock for the hydrogen production process comprises upgraded biogas sourced from a plurality of biogas plants. Each of the upgraded biogases is produced in a process that includes collecting biogas comprising methane and carbon dioxide, capturing at least 50% of the carbon dioxide originally present in the collected biogas and producing the upgraded biogas. Storage of the captured carbon dioxide reducing a carbon intensity of the fuel, without having to provide carbon capture and storage of carbon dioxide from hydrogen production.
Claims23
A method of producing product, the method comprising:
- sourcing at least two upgraded biogases, each of the at least two upgraded biogases produced in a process comprising:
- a) collecting biogas comprising methane and carbon dioxide,
- b) capturing carbon dioxide from the collected biogas and producing upgraded biogas, and
- c) providing the captured carbon dioxide for storage;
- providing the at least two upgraded biogases and fossil-based gas for methane reforming, the methane reforming producing syngas;
- and,
- producing the product from a production process that uses at least part of the syngas produced from the methane reforming,
- wherein the captured carbon dioxide provided in step (c) of each of the processes is stored and reduces lifecycle greenhouse gas (GHG) emissions associated with the product.
A method of producing product, the process comprising:
- (i) sourcing at least two upgraded biogases, each of the at least two upgraded biogases produced in a process comprising:
- a) collecting biogas comprising methane and carbon dioxide, and,
- b) capturing carbon dioxide from the collected biogas and producing upgraded biogas,
- wherein the at least two upgraded biogases and fossil-based gas are used in methane reforming, the methane reforming producing syngas, at least part of the syngas used to produce the product;
- and
- ii) storing the captured carbon dioxide produced from each process, thereby preventing the captured carbon dioxide, or an equal quantity of carbon dioxide displaced by the captured carbon dioxide, from being released to the atmosphere, and reducing lifecycle greenhouse gas (GHG) emissions associated with the product.
A method of producing product, the method comprising:
- providing a plurality of upgraded biogases, each upgraded biogas in the plurality produced in a respective process comprising:
- a) collecting biogas comprising methane and carbon dioxide,
- b) removing at least a portion of the carbon dioxide from the biogas and producing upgraded biogas;
- feeding at least a portion of each upgraded biogas and fossil-based gas to methane reforming, the methane reforming producing syngas, at least part of the syngas used for producing the product;
- and
- wherein at least some of the carbon dioxide removed in step (b) of each of the processes is provided for at least one carbon capture and storage process to reduce lifecycle greenhouse gas (GHG) emissions associated with the product.
