| Abstract |
Electricity storage is a key aspect in mitigating the volatility of renewable energy in sustainable energy systems. Particularly, a new lasting and cost-effective electricity storage technology with a discharge duration of 10 to 100 hours at rated power is required to support the energy time shift and many other stationary electricity storage applications commonly used on the grid today. A high-temperature electricity storage system requires chemical, thermal and mechanical technical approaches to achieve the long-duration and cost-effective electricity storage. This study presents a schematic of the high-temperature electricity storage system. The analysis of the roundtrip efficiency of the system and the levelized cost of storage (LCOS) is conducted based on the various operating conditions. |
