Competitiveness of hydrogen production by glycerol reforming in fixed-bed reactor: An overview of the catalytic performance, product distribution and reactant conversions

Hydrogen can be produced by thermochemical, electrolysis, and bioprocesses. The various process routes for hydrogen production are often constrained by different challenges. The bioprocess is the preferable choice since it is less energy intensive and uses fewer resources at constant temperature and pressure. Nevertheless, the bioprocess is faced with the challenges of the inconsistent rate of hydrogen production. Glycerol has lately emerged as a promising feedstock for hydrogen production, and researchers have examined its potential applications to a great extent. This mini-review focuses on evaluating the competitiveness of producing hydrogen by glycerol reforming in comparison to other processes.
