Hydrogen is the most environmentally friendly and cleanest fuel that has the potential to
supply most of the world's energy in the future, replacing the present fossil fuel-based …

Underground coal gasification (UCG) is a promising option for the future use of un-worked
coal. UCG permits coal to be gasified in situ within the coal seam, via a matrix of wells. The …

The global economic growth, the increase in the population, and advances in technology
lead to an increment in the global primary energy demand. Considering that most of this …

The world is endowed with a tremendous amount of coal resources, which are unevenly
distributed in a few nations. While sustainable energy resources are being developed and …

Biomass has been widely recognized as a clean and renewable energy source, with
increasing potential to replace conventional fossil fuels in the energy market. The …

Green ammonia, produced at ambient conditions, has received significant attention as a
carrier of hydrogen for energy storage and transport. Reduction and oxidation catalytic …

Research on hydrogen production from coal gasification is mainly focused on the formation
of CO and H 2 from coal and water vapor in high-temperature environments. However, in the …

This study aims to elucidate the microscopic mechanism of hydrogen generation from
characteristic groups during the low-temperature oxidation of oil-rich coal. FTIR experiments …

Underground coal gasification can convert deep coal into synthesis gas for use in the
production of electricity, fuels and chemicals. This paper provides a review of the …

Co-gasification contributes significantly to the generation of hydrogen-rich syngas since it
not only addresses the issue of feedstock variation but also has synergistic benefits. In this …
