Huai mining invests in energy storage

Does the Huai'an salt mine have a high energy storage potential?

The Huai'an salt mine has very high energy storage potential. The author's team has been involved in research on the Huai'an salt mine for nearly 20 years. Rock salt, mudstone, and different interlayers have been drilled from the target formation. Many standard mechanical tests have been conducted, providing rich and accurate mechanical [36, 37].

What is the geology of Huai'an salt mine?

The Huai'an salt mine formations are typical lacustrine sedimentary rocks. The geology of the Huai'an salt mine is simple and no obvious faults have been identified in the area of the proposed reservoir. The capping layer consists of brown mudstone with good tightness. The Huai'an salt mine meets the requirements for large-scale CAES salt caverns.

How does Huai'an salt mine work?

At the Huai'an Salt Mine, local salt chemical enterprises cooperate in utilizing the concentrated brine extracted from underground for salt production, while the remaining dilute brine is recycled for cavern construction, maximizing resource utilization.

Does Huai'an salt mine meet the requirements for large-scale CAES salt caverns?

The Huai'an salt mine meets the requirements for large-scale CAES salt caverns. A geomechanical model is established to simulate 6 different internal air pressure (IAP) working conditions.

Why is inter-seasonal energy storage needed in Jiangsu?

The wind source of Jiangsu has typical monsoon characteristics . Thus inter-seasonal energy storage is needed to regulate wind power. As Fig. 2-b shows, Jiangsu has three sites of the salt mine, Jintan salt mine, Huai’an salt mine, and Fengxian salt mine.

How much energy will Jiangsu Province invest in salt caverns by 2050?

Therefore, by 2050, if the energy storage proportion is 15% of wind and solar power generation in Jiangsu Province and the proportion of reconstruction of old and new salt caverns is 50%, the investment in the underground salt cavern will reach 12.1 billion yuan, while the investment in surface equipment will reach 746.7 billion yuan.
