Large-scale storage of hydrogen in salt caverns for carbon footprint reduction

Actual Quality Changes in Natural Resource and Gas Grid Use in Prospective Hydrogen Technology Roll-Out in the World and Russia

“…For large-scale hydrogen storage, the optimal solution is to inject it into underground gas storage facilities, the most efficient of which are salt caverns, as previously recognized. Thus, at this stage, effective large-scale hydrogen storage can only be achieved in regions with favorable geological conditions for this, which implies the active development of technologies for transporting hydrogen from its production sites to direct consumers [31][32][33].…”

“…According to the information provided on the specific cost per 1 kg of liquid hydrogen for various components of the cycles of its synthesis, storage and transportation, mini-plants make it possible to achieve a relatively low cost of the final product, including a CO2 utilization process in the technological cycle (Figure 7).
