How Hydrogen Storage Works. Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure).

The dissociated hydrogen (H 2 –1) is then passed via the expander (T-1) for pressure energy recovery, then through the heat exchanger (E-7) to recover cold energy, and lastly to the hydrogen storage tank (V-2) to complete the hydrogen storage and transport operation. Likewise, the THF solution (AQ-1) recovers cold energy and
