Review and Outlook of Hydrogen Production through Catalytic Processes

Energy & Fuels, Journal Year: 2024, Volume and Issue: 38(4), P. 2601 - 2629

Published: Jan. 28, 2024

Hydrogen holds immense potential as a sustainable energy source result of its eco-friendliness and high density. Thus, hydrogen can solve the environmental challenges. However, it is crucial to produce using approaches in cost-efficient manner. Currently, be produced by utilizing diverse feedstocks, such natural gas, methane, ammonia, smaller organic molecules (methanol, ethanol, glycerol, formic acid), biomass, water. These feedstocks undergo conversion into through different catalytic processes, including steam reforming, pyrolysis, decomposition, gasification, electrolysis, photo-assisted methods (photoelectrochemical, photocatalysis, biophotolysis). Researchers have extensively explored various catalysts, metals, alloys, oxides, non-oxides, carbon-based materials, metal–organic frameworks, for these methods. The primary objectives been attain higher activity, selectivity, stability, cost effectiveness generation. efficacy processes significantly dependent upon performance emphasizing need further research development create more efficient catalysts. during production, gases like CO2, O2, CO, N2, etc. are alongside hydrogen. Separation techniques, pressure swing adsorption, metal hydride separation, membrane employed obtain high-purity Furthermore, techno-economic analysis indicates that production reforming gas/methane currently viable commercially successful. Photovoltaic electrolysis has commercialized, but still higher. Meanwhile, other phase hold future commercialization.

Sustainable Chemistry for Climate Action, Journal Year: 2023, Volume and Issue: 2, P. 100024 - 100024

Published: Jan. 1, 2023

Hydrogen (H2) usage was 90 tnes (Mt) in 2020, almost entirely for industrial and refining uses generated completely from fossil fuels, leading to nearly 900 Mt of carbon dioxide emissions. However, there has been significant growth H2 recent years. Electrolysers' total capacity, which are required generate electricity, multiplied the past years, reaching more than 300 MW through 2021. Approximately 350 projects reportedly under construction could push capacity 54 GW by year 2030. Some other 40 totalling output 35 planning phase. If each these is completed, global production electrolysers exceed 8 It's an opportunity take advantage H2S prospects be a crucial component clean, safe, cost-effective sustainable future. This paper assesses situation regarding at moment provides recommendations its potential future advancement. The study reveals that clean experiencing significant, unparalleled commercial political force, with amount laws all over globe growing quickly. concludes order make widely employed, it significantly increase innovations reduce costs. practical implementable suggestions provided industries governments will allow them fully capitalise on this momentum.

Next-Generation Green Hydrogen: Progress and Perspective from Electricity, Catalyst to Electrolyte in Electrocatalytic Water Splitting

Nano-Micro Letters, Journal Year: 2024, Volume and Issue: 16(1)

Published: July 5, 2024

Green hydrogen from electrolysis of water has attracted widespread attention as a renewable power source. Among several production methods, it become the most promising technology. However, there is no large-scale system currently that can compete with conventional fossil fuel production. Renewable energy electrocatalytic splitting an ideal technology environmental cleanliness protection and good purity, which meet requirements future development. This review summarizes introduces current status by three aspects: electricity, catalyst electrolyte. In particular, present situation latest progress key sources power, catalytic materials electrolyzers for are introduced. Finally, problems generation electrolytic directions next-generation green in discussed outlooked. It expected this will have important impact on field water.
