Mixed metal oxides in catalytic ammonia cracking process for green hydrogen production: A review

International Journal of Hydrogen Energy, Journal Year: 2024, Volume and Issue: 63, P. 828 - 843

Published: March 22, 2024

Hydrogen, a versatile energy carrier, is promising alternative to replace the environmentally harmful and unsustainable use of fossil fuels. This much-touted fuel future may however have pitfalls, such as issues associated with hydrogen production, storage, distribution. Hydrogen storage distribution are concerned various technical, environmental safety issues. Indirect methods – in solid-state materials, ammonia, methanol/ethanol recently being considered by academic industry parties. Ammonia (NH3) can be carbon-free carrier high density, established transportation network, contents flexibility. production from NH3 decomposition requires catalyst/support metal oxides. In binary oxides like perovskites spinels, their unique morphologies structural flexibility enable apply defined control over reaction profile through detailed engineering material design. The focus this study conduct comprehensive review on existing emerging mixed catalysts used process production. activity oxide critically assessed, resulting performances discussed detail. Furthermore, covers challenges catalytic cracking process.

Renewable Hydrogen from Biomass: Technological Pathways and Economic Perspectives

Energies, Journal Year: 2024, Volume and Issue: 17(14), P. 3530 - 3530

Published: July 18, 2024

Hydrogen is undeniably one of the most promising options for producing energy with minimal environmental impact. However, current hydrogen production still derived from carbon-intensive processes relying on fossil fuels. Biomass a sustainable and versatile resource that can be converted into through biological thermochemical pathways large variety feedstocks technologies. This work reviews compares existing biomass-to-hydrogen technologies, focusing their characteristics, maturity level, benefits, limitations, techno-economic lifecycle impacts. Less-developed conversion methods are characterized by low efficiencies productivity. More mature routes enable higher yields. Overall, while suit centralized large-scale production, offer decentralized options, necessitating continued innovation integration future strategies. Some these such as anaerobic digestion (best-case: 1.28 EUR/kgH2) conventional gasification 1.79 EUR/kgH2), emerge promising, sustainable, affordable alternatives renewable generation, offering costs comparable to those natural gas steam reforming (0.92–2.8 EUR/kgH2).
