Towards reforming technologies for production of hydrogen exclusively from renewable resources

Abstract

Stern standards on the quality of hydrocarbon fuels, particularly on sulphur and aromatic content, is one of the major drivers of increasing hydrogen demand by petroleum refineries. The fuel standards are often predicated on reducing environmental pollution. However, most commercial hydrogen production processes are based on non-renewable resources which are associated with high carbon footprints. With increasing demand of hydrogen, the carbon footprint associated with hydrogen production will increase accordingly. Incentives for green hydrogen production technologies will be an impetus toward smooth succession of industrial processes from high to low carbon footprint. It will engender a shortened learning curve and facilitate entry of green reforming technologies into the hydrogen market. This review examines the potential of some emerging reforming technologies for hydrogen production from renewable resources.

A comparative study of CO2 utilization in methanol synthesis with various syngas production technologies

“…1), Scenario 2 could have furthest sustainable MeOH production (i.e., 100% carbon-free) because it consumes the least amount of CH 4 and requires carbon-free H 2 supplied from carbonfree water splitting plant. This hydrogen requirement will potentially create incentive for R&D to drive the development of a sustainable carbon-free hydrogen sector to provide sufficient carbon-free hydrogen for novel global MeOH production [15]. Whereas, in Scenario 3 (bireforming) H 2 in H 2 O is extracted by supplying heat (i.e., from NG combustion) into the reformer, thus it still depends extensively on fossil fuel.…”

“…More importantly DMR-based MeOH requires carbon-free hydrogen (Reaction (a)). This hydrogen requirement will potentially create incentive for R&D to drive the development of a sustainable carbon-free hydrogen sector to provide sufficient carbon-free hydrogen for novel global MeOH production [15].…”

Hydrogen generation from biomass materials: challenges and opportunities

“…BHP processes are much dependent on the presence of a hydrogen‐producing enzyme. Hydrogenases (two subcategories, hydrogenases and reversible hydrogenases) and nitrogenases are two known enzymes that catalyze biological hydrogen production …”

Transformation of Sorbitol to Biofuels by Heterogeneous Catalysis: Chemical and Industrial Considerations

“…Indeed, a process can only be considered green if it is independent of fossil resources, including the hydrogen supply. The APR of biomass-derived products [124,125], the use of photocatalysis are under study for the production of "green" hydrogen [126]. Huber and Dumesic [21] have thus developed the concept of an integrated biorefinery using APD/H as the central process, with the production of hydrogen [21,115].…”
