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.

Are coal-fired power plants a good source of energy in Brazil?

Although Brazil has a high share of renewable generation, fossil sources still play a significant role, with coal-fired power plants contributing to large emissions. The Jorge Lacerda Complex is the largest coal-fired power plant in Brazil.

Why do we use coal to develop underground space resources?

While making full use of coal to develop underground space resources, it realizes power conversion and storage, stabilizes the power system's cycle and voltage, promotes the circulation of mine water, and guarantees flood storage and water transfer.

Will Brazil hold a large-scale energy storage auction in 2025?

The Brazilian authorities say they plan to hold a large-scale energy storage auction in 2025, potentially creating a market for large-scale storage facilities in the country. From pv magazine Brazil
