Description:
Under EPA’s Environmental Technology Verification program, which provides objective and scientific third party analysis of new technology that can benefit the environment, a combined heat and power system based on the UTC Fuel Cell's PC25C Fuel Cell Power Plant was evaluated. The PC25C is a phosphoric acid fuel cell capable of producing a nominal 200 kW of electrical power with an additional 205 kW of heat. Prior to use as fuel, the anaerobic digester gas must be processed through a gas processing unit to remove hydrogen sulfide. The PC25C power module consists of a fuel processor, the fuel cell stack, and the power conditioner. Catalytic steam reforming modifies the digester gas and the fuel cell stack uses phosphoric acid electrolyte to generate direct current power. The testing was at the Red Hook plant in New York State, and provided power that would otherwise be purchased from the utility grid.
