Abstract
A method and device for sustainable, simultaneous production of energy in the forms electricity, hydrogen gas and heat from a carbonaceous gas, the method having the following steps: 1. continuously dividing a feed charge of carbonaceous gas into a first feed gas flow and a second feed gas flow, 2. charging the first feed gas flow to a primary SOFC to produce electricity and heat and CO2, 3. charging the other feed gas flow, to a hydrogen gas forming reactor system to produce hydrogen and CO2, 4. heating the hydrogen gas forming system at least partially by heat developed in at least one SOFC, 5. optionally capturing the CO2 formed in the primary SOFC by burning the “afterburner” gases in pure oxygen and drying the exhaust gas, 6. capturing the CO2 formed in the hydrogen gas forming reactor system by use of an absorbent.
