Abstract

The invention discloses a liquefied carbon dioxide energy storage system and application thereof. The liquefied carbon dioxide energy storage system adopts carbon dioxide as an energy storage medium,an artificial container can be used more flexibly, the energy density of the system is improved, the system forms a closed loop, and greenhouse gas can be prevented from being released to the environment; and on the other hand, the liquefied carbon dioxide energy storage system can achieve power grid frequency modulation and peak load shifting, and the renewable energy utilization rate is increased. The liquefied carbon dioxide energy storage system comprises a first compressor, a first cooler, a first hot tank, a first cold tank, a second heater, a first expander, a third expander, a cold regenerator, a throttle valve, a first liquid carbon dioxide storage tank, a second cold tank, a third cooler, a third heater, a second hot tank, a fourth heater, a fifth pump, a third cold tank, a second liquid carbon dioxide storage tank, a third hot tank, a separator, a fourth expander and a fourth cooler.

Description

technical field [0001] The invention belongs to the technical field of carbon dioxide energy storage, in particular to a liquefied carbon dioxide energy storage system and its application. Background technique [0002] As more and more countries pay attention to energy conservation and emission reduction, energy storage technology, as an important means to smooth the fluctuation of renewable energy, realize peak regulation and frequency regulation of traditional power system, and improve the flexibility of grid connection of renewable energy, has developed rapidly. . Compressed air energy storage is an important energy storage technology. Its working principle is to use excess electric energy to compress air and store it in the air storage cavity during the low peak period of electricity consumption; release high-pressure air during the peak period of electricity consumption, and the air passes through After heating, work will be done in the expander to drive the generator ...
