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).
Schematic diagram of superconducting magnetic energy storage (SMES) system. It stores energy in the form of a magnetic field generated by the flow of direct current (DC) through a superconducting coil which is cryogenically cooled. The stored energy is released back to the network by discharging the coil. Table 46.
