Biohydrogen Production via Thermochemical and Biological Routes
Abstract: Hydrogen is a crucial energy vector for developing a sustainable bioeconomy and can be produced from renewable biomass sources. This review explores various biological and thermochemical pathways for biomass-to-hydrogen conversion. Thermochemical processes include pyrolysis, gasification, fast pyrolysis, steam reforming, and supercritical water gasification, while biological approaches encompass photofermentation, dark fermentation, mixed fermentation, and bio- photolysis. Despite its potential, achieving reliable and selective hydrogen production is essential for economically viable industrial …

Nanoscale Metal Oxide Improvement for Photoelectrochemical Water Splitting and Hydrogen Generation
Abstract: The global pursuit of clean and renewable energy has spotlighted hydrogen as a sustainable fuel, particularly when generated through environmentally friendly methods. Among these, photoelectrochemical (PEC) water splitting stands out as a direct and solar-powered approach to hydrogen (H₂) production. Unlike conventional techniques that rely heavily on fossil fuels, PEC systems utilize semiconductor materials to absorb sunlight and catalyze the splitting of water into hydrogen and oxygen, without releasing harmful …

Quantitative Consequence Analysis of Selected Accident Scenarios at a Refuelling Station for Hydrogen Vehicles
Abstract: AbstractThe implementation of hydrogen economy and energy systems in any nation will require introduction of a large number of hydrogen refueling stations for hydrogen based automobiles. These will be expected to store a significant inventory of hydrogen on site, either as a compressed gas with pressure of about 750 bar or as a cryogenic liquid at 20 K. Not only does the handling of compressed gases and cryogenic liquids present …

Statistical analysis of embodied carbon emissions intensity of hydrogen produced in India by grid connected water electrolysers
Abstract: Electrolytic hydrogen produced through alkaline water or proton exchange membrane electrolysers using clean electricity sources has the potential to contribute to industrial decarbonization by displacing fossil fuels like natural gas, as a low carbon feed material or energy carrier. To have favourable economics of hydrogen production, it is necessary to operate electrolysers continually to make the best use of the installed capacity and associated capital investment. This can be ensured …
