Technical FAQs 4

Can underground space energy storage technology be used in abandoned coal mines?

The underground space resources of abandoned coal mines in China are quite abundant, and the research and development of underground space energy storage technology in coal mines have many benefits.

Can compressed air energy storage be used in coal mines?

However, the key issues, such as the uneven heat transfer of the system and the corrosion and scaling of the heat transfer medium, need to continue to be addressed. (3) The potential for compressed air energy storage in coal mines' underground spaces is enormous, and it can be used with less costly excavation.

How to promote coal mine energy storage?

(3) Provide financial incentives, such as subsidies, tax breaks and investment incentives, to attract investors to participate in coal mine energy storage projects. (4) Support technological innovation and R & D to promote the application and commercialization of new technologies in the field of coal mine energy storage.

How safe is underground electrochemical energy storage in coal mines?

Because underground electrochemical energy storage in coal mines needs to be equipped with a large number of batteries, it requires laying a large number of wires, which may lead to fires, so CUEES needs to be equipped with a complete and effective safety monitoring and protection system during operation to ensure safe operation. 6.2.
