A Chinese research group has combined compressed CO2 with combined heating and power (CHP) units for renewable energy storage. The system has achieved a total exergy efficiency of 35.96% and an energy storage density of 1.54 kWh/m3.Researchers at the Southeast University in China have investigated the possibility of coupling compressed carbon dioxide (CO2) with a combined heating and power (CHP) unit for the storage of solar and renewable energy. The proposed solution is a closed-cycle system with a 600 MW CHP unit and a carbon dioxide energy storage (CCES) facility. It utilizes heat from the ...Den vollständigen Artikel lesen ...
