Abstract
Method and power plant comprising a Solid Oxide Fuel Cell (SOFC) for production of electrical energy and H2 gas. The power plant is charged with a feed gas selected from the group consisting of natural gas, bio-gas and syngas. The feed gas, prior to being fed to the SOFC, is reformed in a reformer with a CaO containing CO2 absorber, thereby producing a carbon free H2 gas as feed for the SOFC while converting CaO to CaCO3. The latter is regenerated to CaO in an endothermic reaction in a CaO regenerator at a temperature of at least 850° C. utilizing heat from the SOFC to heat the regenerator. A heat exchange medium collects heat in the SOFC and is subjected to further temperature increase in a heating device before being subjected to heat exchange in the CaO regenerator.
