Solar photovoltaic-driven water electrolysis (PV-E) is a clean and sustainable approach of hydrogen production, but with major barriers of high hydrogen production costs and limited capacity.
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.

According to a study, it was stated that 11% of the total energy need will be met by hydrogen energy in 2025 and 34% in 2050. [27]. It is stated that, depending on the production of hydrogen energy, coal use will decrease by 36.7% and oil use will decrease by 40.5% in 2030 [28].
Seasonal variation: Hydrogen can also be used to shift the renewable resources across the seasons due to the seasonal difference in energy production. Moreover, hydrogen storage capacity can reach up to MWh, even TWh, owing to its high energy density[63], .
Hydrogen can be extracted from fossil fuels and biomass, from water, or from a mix of both. Natural gas is currently the primary source of hydrogen production, accounting for around three quarters of the annual global dedicated hydrogen production of around 70 million tonnes. This accounts for about 6% of global natural gas use.
Seasonal variation: Hydrogen can also be used to shift the renewable resources across the seasons due to the seasonal difference in energy production. Moreover, hydrogen storage capacity can reach up to MWh, even TWh, owing to its high energy density, while batteries tend to be used in kWh to MWh applications, i.e. one
Hydrogen, known for its high energy density and clean combustion, contributes to improved combustion efficiency and a reduced environmental impact. Ammonia, on the other hand, contains no carbon atoms, which eliminates the production of carbon dioxide and other harmful greenhouse gases during combustion [9].
