Description

technical field

[0001] The invention belongs to the technical field of energy storage and energy utilization, and relates to a carbon dioxide energy storage and energy supply system. Background technique

[0002] Energy storage technology can realize the effective storage of energy and complete the efficient release of energy when needed. Using energy storage technology, the energy supply system can convert surplus energy into cold energy at any time, and use carbon dioxide for low-temperature storage, thereby effectively reducing energy waste. How to use carbon dioxide as a carrier to realize the energy storage and energy supply of the energy supply system, improve the utilization rate of energy, and reduce the waste of energy is an important challenge for the energy supply system.

[0003] Energy storage and supply systems using carbon dioxide as the working medium are relatively rare. Carbon dioxide is a non-toxic, non-flammable, high-density, suitable critical point (c...
