Hydrogen can be stored in three ways: As a compressed gas in high-pressure tanks. As a liquid in dewars or tanks (stored at -253°C). As a solid by either absorbing or reacting with metals or chemical compounds or storing in an alternative chemical form
Hydrogen shows promise as an energy storage solution, and researchers are developing materials that can help store hydrogen for long durations at low cost and high energy efficiency. large pores within the crystals can store hydrogen gas. Hydrides chosen for storage applications provide low reactivity (high safety) and high hydrogen storage densities. Leading candidates are lithium hydride, sodium borohydride, lithium aluminium hydride and ammonia borane.
This is how NASA store Hydrogen
Because liquid oxygen and liquid hydrogen are both cryogenic, gases that can be liquefied only at extremely low temperatures, they pose enormous technical challenges. Liquid hydrogen must be stored at minus 423°F and handled with extreme care. To keep it from evaporating or boiling off, rockets fuelled with liquid hydrogen must be carefully insulated from all sources of heat, such as rocket engine exhaust and air friction during flight through the atmosphere. Once the vehicle reaches space, it must be protected from the radiant heat of the Sun. When liquid hydrogen absorbs heat, it expands rapidly; thus, venting is necessary to prevent the tank from exploding. Metals exposed to the extreme cold of liquid hydrogen become brittle. Moreover, liquid hydrogen can leak through minute pores in welded seams. Solving all these problems required an enormous amount of technical expertise in rocket and aircraft fuels cultivated over a decade by researchers at the National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory in Cleveland. Today, liquid hydrogen is the signature fuel of the American space program and is used by other countries in the business of launching satellites. In addition to the Atlas, Boeing's Delta III and Delta IV now have liquid-oxygen/liquid-hydrogen upper stages.
