摘要: Hydrogen is stored in bulk quantities liquid form 360 and 3800 cubic meter tanks gas underground. The two techniques of underground storage for hydrogen the future are analogous to those used natural gas. Cavities created by dissolving salt layers, affording volume capacities order 100,000 m3, make it possible store a few million meters H2. Storage facilities aquifers fitted out same way as fields provide 100 1000 m3. This paper gives technical description both types illustrates economic case utilizations with examples: annual daily cavities.
