Hydrogen energy storage (HES) is one of the proven and promising long-term energy storage (months) techniques with the potential to bridge several sectors, such as transport and electricity. Electricity can be converted and stored as hydrogen.
Hydrogen offers a potential energy storage medium because of its versatility. The gas can be produced by electrolysis of water, making it easy to integrate with electricity generation. Once made, the hydrogen can be burned in thermal power plants to generate electricity again or it can be used as the energy source for fuel cells.
Furthermore, electricity storage is cost-effective for shorter periods (up to 110 h of power supply), while hydrogen storage becomes more economical for longer durations of power supply (over 110 h).
Conversely, hydrogen storage boasts higher energy density (500–3000 Wh/L) but lower round-trip efficiency (30–50 %) compared to batteries. Improving the efficiency of hydrogen storage would enhance its viability for long-term electricity storage, minimizing energy loss. Energy transfer for end-use is also a critical aspect of the production chain.
Energy storage can be defined as the process in which we store the energy that was produced all at once. This process helps in maintaining the balance of the supply and demand of energy. Energy storage can also be defined as the process of transforming energy that is difficult to store into a form that can be kept affordably for later use.
Although the technological cost of hydrogen used for transportation is high because of its long chain and low efficiency from electrolysis water to fuel-cell, the cost of hydrogen used for electric energy storage is low , giving it a competitive advantage in the long-term-fixed large-scale energy storage scenario.

Both battery and hydrogen technologies transform chemically stored energy into electrical energy and vice versa. On average, 80% to 90% of the electricity used to charge the battery can be retrieved during the discharging process.
Energy storage with hydrogen, which is still emerging, would involve its conversion from electricity via electrolysis for storage in tanks. From there it can later undergo either re-electrification or supply to emerging applications such as transport, industry or residential as a supplement or replacement to gas.
