6 FAQs about [Cavern gas energy storage]

How can large-scale energy storage be implemented in salt caverns?

Compressed air and hydrogen storage are two main available large-scale energy storage technologies, which are both successfully implemented in salt caverns . Therefore, large-scale energy storage in salt caverns will also be enormously developed to deal with the intermittent and fluctuations of renewable sources at the national or grid-scale.

Are salt caverns a good way to store natural gas?

1. Introduction Salt caverns are the best method for the storage of natural gas due to their large capacity, safety and long operation time [1, 2]. Most previous studies concerning underground gas storage facilities have been limited to pure and homogeneous salt formations in salt domes.

What is the energy scale of hydrogen storage in salt caverns?

The energy scale of hydrogen storage in salt caverns is much larger than that of gas storage in salt caverns. Meanwhile, the volume energy density of hydrogen is only 36% of that of natural gas under the same pressure. Using the same energy storage scale, the volume required for hydrogen storage in salt caverns is 2.77 times that for natural gas.

Are salt caverns a good choice for energy storage?

Among all the underground structures, due to their strong tightness/stability, lower proportion of cushion gas, and good operational flexibility, salt caverns are regarded as the most favorable choice for energy storage―especially for gas, hydrogen and compressed air .

Can underground salt caverns be used for compressed air energy storage?

The future development and challenges of underground salt caverns for compressed air energy storage in China are discussed, and the prospects for the three key technologies of large-diameter drilling and completion and wellbore integrity, solution mining morphology control and detection, and tubing corrosion and control are considered.

Can a salt cavern gas storage system be built directly based on ESC?

If some of the ESC are screened out through technical means and converted into energy storage, then the CAES system or salt cavern gas storage is built directly based on them, which would greatly narrow the construction cycle; a huge energy storage scale will be formed in a short period of time with considerable economic benefits [ 33 ].
