Moon base energy supply system and method based on compressed carbon dioxide energy storage

Abstract

The invention discloses a moon base energy supply system and method based on compressed carbon dioxide energy storage. The system employs a compressed carbon dioxide energy storage technology to achieve the high-capacity and high-density storage of excess electric energy of a photovoltaic system during strong illumination in the month day, and the high-power, stable and controllable release of the surplus electric energy in the month night, solar eclipse and insufficient illumination periods. Meanwhile, parts required by the energy storage system are compact in structure, small in size and light in weight. A solar photo-thermal device is introduced, so that the temperature grade of the heat storage subsystem can be further improved, the storage capacity of the system is further improved, the operation cycle of the energy supply system is prolonged, and stable energy supply of the lunar base is guaranteed. Meanwhile, due to the fact that a heat storage subsystem exists in the system, a moon base heat management system can be developed in the later period, and heat and power cogeneration is achieved. The system and the method have important scientific significance and engineering application value in the aspects of promoting the development of a space energy technology, accelerating the construction of a moon base and the like.

Description

technical field [0001] The invention belongs to the technical field of space energy, and in particular relates to a lunar base energy supply system and method based on compressed carbon dioxide energy storage. Background technique [0002] With the development of human civilization and the advancement of science and technology, the development of deep space exploration is a necessary means to expand the space for future survival and development to the outer space. As the closest celestial body to the earth, the moon naturally becomes the preferred detection target. Although the past period of lunar exploration has discovered that the moon is rich in mineral resources and energy, but human exploration of the moon is still in its infancy and lacks an in-depth understanding of the moon. The in-depth exploration of the moon has attracted the attention of many aerospace powers in the world, and the planning of a lunar base has been put on the agenda. Among the many component sy...
