The employment of bulk hydrogen storage systems within industry appear
s increasingly to be a near-term prospect given the steadily increasin
g levels of hydrogen production. The current study defines and outline
s a cost model through which comparative and informative assessments o
f different stationary bulk hydrogen storage reservoir types can be ma
de. The reservoir types investigated include: mined salt caverns, depl
eted natural gas reservoirs and liquid vessels. Using the model, cost
of storage for these potential bulk hydrogen containment technologies
is estimated and compared in qualitative terms, for similar storage ap
plications. (C) 1997 International Association for Hydrogen Energy.
