6 FAQs about [Cave 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.

Can salt caverns be used for energy storage?

Storage of green gases (eg. hydrogen) in salt caverns offers a promising large-scale energy storage option for combating intermittent supply of renewable energy, such as wind and solar energy. Caverns are artificially created by a controlled dissolution mining process within the host rock formation 1.

Does China support salt cavern energy storage?

The Chinese government currently offers robust support for the salt cavern energy storage industry and has incorporated CAES into the national “14th Five-Year Plan”, thereby providing substantial backing for research on salt cavern CAES.

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.

Why is China so difficult to build energy storage caverns?

China is rich in salt resources, but most of these resources have the characteristics of bedded structures, thin salt layers, and complicated geological conditions, which make it very difficult to construct energy storage caverns in the these strata.

How does a salt cavern store gas?
