Different technologies possibly applicable for the large-scale hydrogen storage in urban or industrial-complex areas have been comparatively evaluated, focusing on the facility-construction cost, the utility expense, and the ground area required for the facility for each technology. The specific technologies examined in this study are the storage in the form of a pressurized of liquefied gas, the storage using a metal hydride, and the storage using a clathrate hydrate. The storage using a clathrate hydrate is found to be superior to the other technologies with respect to every evaluation index employed in this study.
