Abstract

A carbon dioxide energy storage system and a control method thereof are provided. The system includes a gas storage unit, an energy storage component, a liquid storage unit, an energy release component that are sequentially closed-loop connected, and a gas temporary storage unit connected between the energy storage component and the energy release component. Within a first time period after the energy storage component begins operation and within a second time period before the energy storage component stops operation, the gas temporary storage unit is used to receive and store high temperature carbon dioxide gas output from the energy storage component to obtain stored high-temperature carbon dioxide gas. Before the energy release component begins operation, the gas temporary storage unit is used to replace the low-temperature carbon dioxide gas in an energy release pipeline with the stored high-temperature carbon dioxide gas.
