Also, hydrogen is expected to be used as an energy carrier that contribute to the global decarbonization in transportation, industrial, and building sectors. Many technologies have been developed to store hydrogen energy. Hydrogen can be stored to be used when needed and thus synchronize generation and consumption.
Hydrogen storage is a key enabling technology for the advancement of hydrogen and fuel cell technologies in applications including stationary power, portable power, and transportation. Interest in hydrogen energy storage is growing due
Since hydrogen is an energy carrier, it offers the benefit of storing energy for long periods of time and can be used for energy generation whenever desired. Competing mainly with batteries for the energy storage role of the future, hydrogen offers a few advantages that can make it a compelling energy storage asset for future projects.
Storage is at low pressures so rather thin and cheap storage tanks can be used. In the liquid form hydrogen is non-corrosive and stainless steel and aluminum alloy vessels with sufficient insulation are used for the cryogenic storage. However, the cost of liquefaction is high so is the energy used for the liquefaction [1, 9, 18].
It can be used to produce ammonia, which can be used as feedstock for fertilisers (the majority of current use) or as fuel for new applications such as shipping. It can also be used to produce methanol, synthetic fuels, or even as a reducing

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). Storage
Gaseous storage is the most common and the most likely option for expanding hydrogen storage for most hydrogen use as an energy source. Liquid—Hydrogen can be liquefied by cooling it to below -423 o F (−253 o C). Liquefied hydrogen can be stored in super-cooled (cryogenic) tanks for transportation applications in fuel cell vehicles or
Illustrative storage compounds are hydrocarbons, boron hydrides, ammonia, and alane etc. A most promising chemical approach is electrochemical hydrogen storage, as the release of hydrogen can be controlled by the applied electricity.
