FuelCell Energy Inc. has commenced operations of a DFC/T(TM) power plant based on a 250 kW Direct FuelCell(R) integrated with a Capstone Turbine Corporation modified Model 330 Microturbine. The combined system does not require any combustion in the turbine. The first-of-a-kind test of the DFC/T(TM) power plant is being funded by the US Department of Energy. The DFC/T power plant is based on FuelCell Energy’s new design for ultra-high efficiency systems. At the core of this power plant design is the company’s commercial DFC fuel cell technology. The system extends the potential fuel savings and positive environmental attributes of the DFC by combining a non-fired gas turbine and a network of heat exchangers, resulting in extra electricity and adding significantly to the already high efficiency of the DFC.
