“…The levelized cost of hydrogen (LCOH) predicted in Moser et al [71] for ceria oxide two-step cycles is 6.68 €/kg H 2 (8.05$/kg H 2 ) in the best-case scenario. As a benchmark comparison with PV-electrolysis cost, [72] highefficiency solar cells connected to electrolyzers are predicted to permit the production of hydrogen at 5.9$/kg H 2 , while the cost of hydrogen from conventional silicon photovoltaic solar farms and electrolyzers is rated at 4.9$/kg H 2 .…”

Actually, decarbonization of the global economy presents an important challenge for the worldwide. Expanding renewable energy sources and using green hydrogen to merge renewables in many sectors, such as energy, mobility and industries, present a potential key to meet this challenge. Green hydrogen has the potential to plug the fluctuation of wind and solar energy, to serve as feedstock in many industrial processes, and as fuel for transportation. An overview of the different technologies used to generate green hydrogen is presented in this paper. In addition, this paper summarises the different barriers of the development of green hydrogen.

Hydrogen is considered an attractive energy resource because it is eco-friendly in contrast with fossil fuels. Hydrogen storage remains as essential technology for increasing the use of the hydrogen in applications such as hydrogen vehicles and fuel cells. Hydrogen storage requires retaining a high density of hydrogen molecules at ambient temperature in a suitable tank. Zeolites are one of the promising hydrogen storage materials, but experimentally investigating them for hydrogen storage is difficult since the number of the zeolites in the largescale material database has been increasing. In the present study I developed an efficient method of exploring potential zeolites in the database that had high volumetric hydrogen storage capacity. To do this I employed a high-throughput screening approach to automatically construct a zeolite database for hydrogen storage in the Inorganic Crystal Structural Database (ICSD). Also, I performed grand canonical Monte Carlo (GCMC) simulations to estimate hydrogen adsorption isotherms at operating ambient temperatures, to determine the volumetric hydrogen storage capacity of the zeolites. Finally, I found 10 top ranked materials in the zeolite database for H2 storage, and I calculated Pearson’s correlation coefficient to revealed the linear correlations between the hydrogen storage capacities and 3 structural characteristics (i.e., surface area, largest cavity diameter, pore limiting diameter). Furthermore, I investigated atom species in the 10 materials to show the relation between the hydrogen storage capacities and chemical elements. In future works, I expect the method can be easily applied to accelerate the discovery and design of porous materials for storing CO2 or toxic gases.
