Abstract: The method and system for removing CO2 from the atmosphere or the ocean having the steps of, feeding a solid oxide fuel cell (SOFC) system with a gaseous hydrocarbon feed, converting the gaseous hydrocarbon feed in the SOFC system into an anode exhaust stream having carbon dioxide CO2, the SOFC system thereby producing electricity; injecting the anode exhaust stream as an injection gas into an underground coal bed; in the underground coal bed the injection gas causing coal bed methane (CBM) to desorb from the coal and CO2 to adsorb onto the coal; extracting the coal bed methane (CBM) from the underground coal bed; and discharging a production gas having the coal bed methane (CBM) from the underground coal bed.

Abstract: A combined hydrogen and electricity supply system for producing hydrogen, electrical Power (P) and co-production, the system including a variable electrical load for varying the amount of impedance on the system, a pre-reformer connected to a stream of carbonaceous fuel, a stream of steam and connected to a heating source. The pre-reformer produces a first reformate gas having at least hydrogen, carbon monoxide and unconverted carbonaceous fuel. The pre-reformer is responsive to the amount of heat provided by the heating source, a solid oxide fuel cell stack coupled to the variable electrical load and coupled to the first reformate gas. The ratio between electrical power (P) and amount of hydrogen produced depends at least on the variable electrical load and the heat provided by the heating source.

Abstract: A SOFC system having a fuel reformer for reforming a gaseous hydrocarbon stream and steam into a hydrogen rich gas, a solid oxide fuel cell stack including an anode and a cathode for electrochemically reacting the hydrogen rich gas and a cathode air stream to produce electricity, an anode exhaust stream and a cathode depleted air stream. The anode exhaust stream and the cathode depleted air stream are kept separate, a burner for combusting a mixture of the anode exhaust stream and a fresh air stream to complete combustion and produce heat for the reformer control unit and a blower are also provided. The control unit controlling the blower for controlling the mass flow rate of the fresh air stream to provide heat to the reformer to reform the gaseous hydrocarbon stream and to produce a burner exhaust stream.

Abstract: Method and system for producing CO2, purified hydrogen and electricity from a reformed process gas feed using a solid oxide fuel cell. The method having the steps of: introducing the reformed process gas into the solid oxide fuel cell; converting hydrogen and CO of the reformed process gas in combination with oxygen into an anode off-gas including steam, CO2 and unconverted process gas; introducing the anode off-gas into a high temperature water gas shift reactor; in the high temperature water-gas shift reactor, converting CO and steam into CO2 and hydrogen, introducing the gas exiting the high temperature water-gas shift reactor into a low temperature water-gas shift membrane reactor, in the low temperature water-gas shift membrane reactor, converting CO and steam into CO2 and hydrogen, whereby the low temperature water-gas shift membrane reactor comprises a hydrogen pump producing purified hydrogen on a permeate side, while removing hydrogen from a feed side.

Abstract: Disclosed is a solid oxide fuel cell (SOFC) positive electrolyte negative (PEN) comprising electrodes on the rear side thereof used for establishing contact between a flat interconnecting plate and a raised structure which is configured in such a way that it forms gas circulation channels with said plate. The PEN and interconnecting plates can have holes so as to create internal gas inlet and outlet tubes. The electrolyte/electrode interface can also be configured as a raised structure increasing the ratio of the extended area to the projected area.
