摘要
An electric-thermal energy storage called a Carnot Battery has been emphasized as a solution for large-scale and long-duration energy storage to compensate for the intermittent nature of renewables at the grid level. It is composed of electricity-to-heat, heat storage, and heat-to-electricity systems. In regard to the heat-to-electricity system, a supercritical carbon dioxide power cycle (sCO2) is an attractive option, owing to advantages including a wide operating range for diverse heat sources, dry-cooling, high efficiency, and a small footprint. The Korea Institute of Energy Research (KIER) has developed sCO2 power cycle test loops with various types and capacities for turbomachinery. In this study, the concept of the Carnot Battery and the development of the KIER sCO2 power cycle system are presented.
