A Primer on SOFC Technology
SOFC Power Systems
SOFC power generation applications can range from small (e.g., 3 to 10 kWe) power systems for the home or small business, or as auxiliary power units (APU's) for the transportation industry, to intermediate (e.g., 100 kWe to tens of MWe) systems for larger commercial or industrial sites, to as large as multi-100 MWe central station, power plants. The systems can be designed to operate on a variety of fuels, such as H2, natural gas, liquid fuels (e.g., propane, JP-8, diesel), and, for large plants, coal-derived fuel gas (syngas). The electrical efficiency potential is ~50% (net AC/LHV natural gas) for small SOFC power systems, ~60% (net AC/LHV natural gas) for intermediate-scale systems, and up to 60% (net AC/HHV coal) for the large central station SOFC power plants - referred to as Integrated Gasification Fuel Cell (IGFC) systems. IGFC systems are the focus of development under the SECA Program. Information concerning IGFC system configurations and performance studies can be found on the SECA website.
