Biomass gasification produces syngas composed mainly of hydrogen carbon monoxide carbon dioxide methane water and higher hydrocarbons till C4 mainly ethane. The hydrocarbon content can be upgraded into richer hydrogen streams through the steam reforming reaction. This study assessed the steam reforming process at the thermodynamic equilibrium of five streams with different compositions from the gasification of three different biomass s Read More

Anion exchange membrane water electrolysis (AEMWE) is a potentially low-cost and sustainable technology for hydrogen production that combines the advantages of proton exchange membrane water electrolysis and traditional alkaline water electrolysis systems. Despite considerable research efforts in recent years the medium-term (100 h) stability of Aemion™ membranes needs further investigation. This work explores the chemical and electroc Read More

Reserves of fossil fuels such as coal oil and natural gas on earth are finite. The continuous use and burning of these fossil fuel resources in the industrial domestic and transport sectors has resulted in the extremely high emission of greenhouse gases GHGs (e.g. CO2) and solid particulates into the atmosphere. Therefore it is necessary to explore pollution free and more efficient energy sources in order to replace depleting fossil fuels. The use of hydrogen Read More

There is a pressing need to rapidly and massively scale up negative carbon strategies such as carbon capture and storage (CCS). At the same time large-scale CCS can enable ramp-up of large-scale hydrogen production a key component of decarbonized energy systems. We argue here that the safest and most practical strategy for dramatically increasing CO2 storage in the subsurface is to focus on regions where there are multiple partially deplete Read More

Green hydrogen (H2 ) has emerged as a promising energy carrier for decarbonizing the industrial building and transportation sectors. However current green H2 production technologies face challenges that limit cost reduction and scaling up. Platinum-group metals (PGMs) including platinum and iridium present exceptional electrocatalytic properties for water splitting but their high cost is a significant barrier. This directly impacts the overall cost of electrol Read More

Hydrogen is expected to play a critical role in future energy systems projected to have an annual demand of 401–660 Mt by 2050. With large-scale green hydrogen projects advancing in water-scarce regions like Australia Chile and the Middle East and North Africa understanding water requirements for large-scale green hydrogen production is crucial. Meeting this future hydrogen demand will necessitate 4010 to 6600 GL of demineralised water annuall Read More

Water electrolysis is a promising technology for sustainable energy conversion and storage of intermittent and fluctuating renewable energy sources and production of high-purity hydrogen for fuel cells and various industrial applications. Low-temperature electrochemical water splitting technologies include alkaline proton exchange membrane and anion exchange membrane water electrolyses which normally consist of two coupled half reactions: the Read More
