  • Patent number: 12152774
    Abstract: A system for offshore, direct carbon dioxide sequestration includes an offshore marine platform fixed to the ocean floor above an offshore, subsea storage reservoir. A carbon dioxide floating storage unit moored adjacent the marine platform gathers and stores carbon dioxide delivered in discreet amounts from carbon dioxide sources. Carbon dioxide sources may include carbon dioxide delivery vessels and a carbon dioxide capture system mounted on the marine platform. Once a desired volume of carbon dioxide has been gathered in the carbon dioxide floating storage unit, compressors in fluid communication with the carbon dioxide floating storage unit may be utilized to increase the pressure of the gathered carbon dioxide to a desired injection pressure, after which the pressurized carbon dioxide is pumped directly from the fixed marine platform into the subsea storage reservoir.

  • Publication number: 20240286729
    Abstract: A system for marine electricity generation and solid carbon production includes an offshore marine platform on which is mounted a regassification system for regassification of liquid methane; a methane splitting system producing solid carbon and gaseous hydrogen; and a power generation system producing electricity and exhaust heat. A first marine vessel is moored adjacent the marine platform for delivery of the liquid methane, and a second marine vessel is moored adjacent the marine platform for removal of the solid carbon produced by the methane splitting system. The hydrogen produced from the methane splitting system is used in a fuel stream for the power generation system. The exhaust heat from the power generation system is utilized in the methane splitting process. Also mounted on the marine platform is a solid carbon handling system disposed to manage the large amount of solid carbon resulting from the methane splitting process.

  • Patent number: 11873991
    Abstract: A system for offshore electricity generation and direct carbon dioxide sequestration includes an offshore marine platform on which is mounted a plurality of internal combustion engines. The marine platform is deployed above an offshore, subsea storage reservoir. The internal combustion engines drive electric generators to produce electricity. Flue gas from the internal combustion engines is directed to a carbon dioxide capture system adjacent the internal combustion engines and in fluid communication with the flue gas exhausts of the internal combustion engines. The carbon dioxide capture system captures gaseous carbon dioxide from the flue gas, and then injects the captured carbon dioxide directly into the offshore, subsea storage reservoir. Compressors in fluid communication with the carbon dioxide capture system may be utilized to increase the pressure of the captured gaseous carbon dioxide to a desired injection pressure.
