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.
In liquid hydrogen storage, hydrogen is cooled to extremely low temperatures and stored as a liquid, which is energy-intensive. Researchers are exploring advanced materials for hydrogen storage, including metal hydrides, carbon-based materials, metal–organic frameworks (MOFs), and nanomaterials.
Ammonia is considered to be a potential medium for hydrogen storage, facilitating CO2-free energy systems in the future. Its high volumetric hydrogen density, low storage pressure and stability for long-term storage are among the beneficial characteristics of ammonia for hydrogen storage. Furthermore, ammonia is also considered safe due to

As it can be seen from Table 2, the AB 5-type materials with different Ce/La ratios and AB 2-type ones with different Zr/Ti ratios (both from the A side) allow to develop on their basis various hydrogen storage and compression systems operating in various ranges of temperatures and H 2 pressures. pressures.
This study discusses and thermodynamically analyzes several energy storage systems, namely; pumped-hydro, compressed air, hot water storage, molten salt thermal storage, hydrogen,
Mechanical systems for energy storage, such as Pumped Hydro Storage (PHS) and Compressed Air Energy Storage (CAES), represent alternatives for large-scale cases. PHS, which is a well-established and mature solution, has been a popular technology for many years and it is currently the most widely adopted energy storage technology [
Hydrogen storage is one of the main challenges to be overcome for the widespread use of hydrogen as an energy carrier because of the low density of H 2 gas even at high pressures [3]. Solid-state hydrogen storage in metal hydrides is one of the alternatives to efficiently store and transport large amount of hydrogen in relatively small

Once produced, hydrogen can be stored for later use either as a compressed gas, as a liquid at very low temperatures, or in solid-state host materials. In her article, which will appear in an upcoming issue of MRS Bulletin, Milanese et al. 5 discuss the challenges and opportunities of hydrogen storage in metal-hydride materials.
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.
Dihydrogen (H2), commonly named ''hydrogen'', is increasingly recognised as a clean and reliable energy vector for decarbonisation and defossilisation by various sectors. The global hydrogen demand is projected to increase from 70 million tonnes in 2019 to 120 million tonnes by 2024. Hydrogen development should also meet the seventh goal of ''affordable
