Abstract

Liquid carbon dioxide energy storage (LCES) is considered a promising energy storage technology due to its high energy density and low environmental impact. However, additional pumps or throttling valves are required during the energy release process, leading to additional energy consumption and loss. This paper proposes a novel LCES system improved by an ejector and solar thermal collector for sustainable power and heat supply, and improve the efficiency of LCES system by avoiding part of throttling loss. The thermodynamic model of the novel system is established and the simulation is carried out. The gas dynamic function method was used to calculate and design the geometry of ejector and the reliability and accuracy were verified using a CFD simulation. In addition, the performance of the novel system was evaluated by energy, exergy and economic analysis. The results showed that the optimal entrainment ratio of the ejector for the novel LCES system is 0.17; and the round-trip efficiency is 68.94 %, which is an improvement of 10.15 %, compared with the conventional LCES system. The energy storage density is 17.86 kWh/m3, and the exergy efficiency is 81.26 %. The total investment of novel system is 6643.59 k$ with a dynamic payback period of 4.76 years and a net present value of 7382.44 k$. In addition, In addition, the effects of variations in some of the main parameters on the performance of the system are investigated. This paper may provide a feasible solution for the performance enhancement of LCES system.
