Hydrogen fuel production from sugarcane and its byproducts – a critical review

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The transition to a low‐carbon economy has intensified the search for sustainable hydrogen (H2) production routes. Sugarcane and its byproducts, such as bagasse, molasses and vinasse, have emerged as promising feedstocks due to their ready availability and renewable nature. However, comprehensive evaluations of the efficiency, limitations, and
