WebOct 30, 2014 · The SWPC SOFC power systems are equipped to operate on lower number hydrocarbon fuels such as pipeline natural gas, which is desulfurized within the SOFC power system. Because the system more » operates with a relatively high electrical efficiency, the CO2 emissions, {approx}1.0 lb CO2/ kW-hr, are low. Web14 hours ago · Until a few years ago, the SOFC role was relegated to the provision of power in utility scale applications due to the significant time required to reach the operating temperatures. Nonetheless, the high working temperature allows to work not only with pure hydrogen but also with any king of rich hydrocarbon fuels such as natural gas or syngas.
