Demonstration of CO_2 Capture from a Solid Oxide Fuel Cell

摘要

A 250 kW tubular SOFC fuel cell adapted to recover CO_2 will be demonstrated at a coastal site in Norway. The cell uses a solid state after-burning device to complete the oxidation of the fuel without introduction of air into the exhaust fuel stream. This is essential to prevent dilution of the exhaust gas with nitrogen, which would otherwise reduce the purity of the captured CO_2. The project will also demonstrate effective sealing between anode and cathode gas streams which is another a key requirement for effective CO_2 capture from a fuel cell. Overall the project is intended to show that power can be generated from natural gas in industrial quantities with high efficiency whilst capturing all of the CO_2 produced. In order to further demonstrate sustainability principles it is planned to provide power and heat to an adjacent fish farm project and to reuse the CO_2 as a nutrient for the algae upon which the fish will feed.
