Renewable energy comprehensive utilization system based on compressed carbon dioxide energy storage

Abstract

According to the renewable energy comprehensive utilization system based on compressed carbon dioxide energy storage, liquid carbon dioxide is used for providing a cold source, a solar heat collection assembly is used for providing a heat source, the defects of volatility, randomness and the like of renewable energy can be effectively overcome, the heat supply and power supply quality is improved, and the heat supply and power supply stability is improved. The opening degree of the valve can be adjusted according to heat requirements and electric energy requirements of different heat exchange sections in actual life, the energy supply share is adjusted, and heat supply and power supply distribution is achieved. Meanwhile, the combined structure of the solar cell panel and the heat accumulator can effectively solve the intermittent influence of the illumination intensity caused by the change of natural factors. The system is simple in equipment, compact in structure, free of pollution and free of emission, effectively utilizes a cold source and a heat source of the system, achieves gradient utilization of energy and has high economic benefits.

Description

technical field [0001] The invention belongs to the technical field of energy utilization, and in particular relates to a system for comprehensive utilization of renewable energy based on compressed carbon dioxide energy storage. Background technique [0002] The massive emission of carbon dioxide is one of the important reasons for global warming. Among them, carbon capture and carbon storage is one of the most important means. Because it can reduce carbon dioxide emissions on a large scale, it has become an emerging emission reduction means to deal with global warming. At the same time, renewable energy sources such as solar energy, wind energy, and water energy have attracted the attention of all countries in the world. Compared with traditional energy sources such as coal, oil, and natural gas, the popularization of clean energy has become the expectation of people around the world. [0003] Energy storage technology is one of the key technologies to solve the large-sca...
