Large-scale storage of low-pressure, gaseous hydrogen in
salt caverns and other underground sites for transportation fuel and grid-scale
energy applications offers several advantages over above-ground storage, says a
recent Sandia National Laboratories study sponsored by the Department of
Energy’s Fuel Cell Technologies Office.
Geologic storage of hydrogen gas could make it possible to
produce and distribute large quantities of hydrogen fuel for the growing fuel
cell electric vehicle market, the researchers concluded.
