Abstract

It is an effective way to expand the scale of renewable energy utilization by combining energy storage technology with renewable energy. In this paper, a novel energy storage technology based on liquid carbon dioxide storage, low pressure storage and latent cold energy storage is proposed. The main work of this paper is to establish the thermodynamic model of the system, and investigate the influence of key parameters on the performance of the system through parameter analysis. The analysis results show that in a certain range, there are optimal R₄₄₁₉, R₁₂₉, R₂₁₁₈ and R₃₈₃₆ respectively to make round trip efficiency reach the maximum value. Increasing R₁₂₉ and R₂₁₁₈ can improve the energy density of the system.
