Energy storage system (ESS) is a particularly important technology that can help electricity grids to integrate renewable and intermittent energy sources and ensure reliable electricity supply. Safety and cost are the major concern of ESS right now. In this paper, the leverage cost of energy (LCOE) of ESS will be detail analyzed especially the efficiency related coefficient. The target here is to design an ESS with round trip efficiency higher than 90 % with 0.5P. To improve the efficiency and reduce the LCOE of commercial ESS, a SiC based design is introduced and realized. The detail module design and efficiency test are compared based on Si design and SiC based design.
