Global hydrogen production by technology in the Net Zero Scenario, 2019-2030. IEA. Licence: CC BY 4.0. Dedicated hydrogen production today is primarily based on fossil fuel technologies, with around a sixth of the global hydrogen supply coming from "by-product" hydrogen, mainly in the petrochemical industry.
Hydrogen is a versatile energy carrier (not an energy source). It can be produced from multiple feedstocks and can be used across virtually any application (see Figure 1). Renewable electricity can be converted to hydrogen via electrolysis, which can couple continuously increasing renewable energy with all the end uses that are more difficult
For most gaseous hydrogen storage applications; pressure tanks storing compressed hydrogen gas at high pressure is the option most readily utilized and investigated today [11, 28] & [30].

To meet ambitious targets for greenhouse gas emissions reduction in the 2035-2050 timeframe, hydrogen has been identified as a clean "green" fuel of interest. In comparison to fossil fuel use the burning of hydrogen results in zero CO 2 emissions and it can be obtained from renewable energy sources.
Additionally, hydrogen – which is detailed separately – is an emerging technology that has potential for the seasonal storage of renewable energy. While progress is being made, projected growth in grid-scale storage capacity is not currently on track with the Net Zero Scenario and requires greater efforts.
This paper explores the potential of hydrogen as a solution for storing energy and highlights its high energy density, versatile production methods and ability to bridge gaps

Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind. These qualities make it an attractive fuel option for transportation and electricity generation applications.
2 · To mitigate this fluctuation, the development of efficient energy storage systems becomes essential as a priority to develop suitable energy conversion or storage
The advantages of LH 2 storage lies in its high volumetric storage density (>60 g/L at 1 bar). However, the very high energy requirement of the current hydrogen liquefaction process and high rate of hydrogen loss due to boil-off (∼1–5%) pose two critical challenges for the commercialization of LH 2 storage technology.
The production, storage and transportation of ammonia are industrially standardized. However, the ammonia synthesis process on the exporter side is even more energy-intensive than hydrogen liquefaction. The ammonia cracking process on the importer side consumes additional energy equivalent to ~20% LHV of hydrogen.
