The high-temperature thermochemical water splitting (TWS) cycles utilizing concentrated solar energy (CSE) and water are the most promising alternatives to produce renewable hydrogen.
Advanced Fuels and Thermal Energy Research focuses on innovative solutions to build ecosystems for clean hydrogen and other low-carbon alternative fuels. This includes production, transmission, distribution, storage, and adoption of these fuels to help decarbonize hard-to electrify sectors. Clean hydrogen can be produced using renewable energy sources such as
This process involves the conversion of biomass—such as crop residues, forest leftovers, special energy crops, organic waste, and animal manures— into hydrogen, carbon monoxide, and carbon dioxide through high-temperature reactions with steam and oxygen, without direct combustion.
A thermal catalytic process converts ethanol and water into hydrogen and acetic acid at low temperatures with near-zero carbon dioxide production, unlike the conventional methane-reforming process used to make
This paper presents a review of recent research and development progress on green hydrogen energy systems and associated thermal management and waste heat recovery technologies.
Solar thermal hydrogen production needs concentrated solar energy to split water into hydrogen and oxygen to produce high temperatures. The reflector reflects sunlight onto a receiver to produce heat for high-temperature electrolysis or thermochemical reactions.
The case study focuses on the collaborative planning of electric-thermal-hydrogen-coupled energy systems based on the Northeast China power grid, with 2050 as the planning target year.
Thermal Hydrogen is an energy system where electric and/or heat energy is used to split water (or CO2) for the utilization of both byproducts: hydrogen as energy storage and pure oxygen as carbon abatement.
A thermal catalytic process converts ethanol and water into hydrogen and acetic acid at low temperatures with near-zero carbon dioxide production, unlike the conventional methane-reforming process used to make hydrogen.
Thermochemical water splitting processes use high-temperature heat (500°–2,000°C) to drive a series of chemical reactions that produce hydrogen. The chemicals used in the process are reused within each cycle, creating a closed loop that consumes only water and produces hydrogen and oxygen.
