Abstract

Abstract: The power to gas process concept is promising for the next generation of grid electricity storage and stabilization technologies. The electricity-driven fuel production can be chosen to be the efficient energy carrier for excessive grid power. Here, a reversible solid oxide cells system integrated with methane synthesis (ReSOC-MS) is proposed for the grid stabilization application at MW class. Besides H2, CH4 can be inclusively synthesized at grid surplus conditions as a transportation friendly energy carrier. A control strategy is proposed for this combined system, based on the grid state and H2 tank state of the system for the normal SOFC mode and SOEC mode operating. Simulation results of these two modes operating demonstrate that the ReSOC-MS can achieve an 85.34% power to gas efficiency at SOEC mode and 46.95% gas to power efficiency at SOFC mode.
