Levelised cost of storage analysis for an energy storage system based on reversible solid oxide cell technology

Abstract

The levelised cost approach is employed in this study to analyse the cost of a distributed scale standalone reversible solid oxide cell (ReSOC)-based energy storage system. The levelised cost of storage (LCOS) and the storage cost (SC) of the ReSOC system are computed and compared with other storage technologies. The LCOS and SC of the considered system are determined as $0.36/kWh and $0.09/kWh/cycle, respectively. Also, 156 tons/year emission reduction was achieved. The system analysis showed that the scale, capital and electricity cost, and roundtrip efficiency highly influence the system's economic performance.
