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.
Using the same energy storage scale, the volume required for hydrogen storage in salt caverns is 2.77 times that for natural gas. In addition, the peak-shaving of hydrogen storage in salt caverns is rated higher, which is estimated to be 6 ∼ 12 times per year, while the average gas storage is twice per year.
With the demand for peak-shaving of renewable energy and the approach of carbon peaking and carbon neutrality goals, salt caverns are expected to play a more effective role in compressed air energy storage (CAES), large-scale hydrogen storage, and temporary carbon dioxide storage.
