Carbon‐negative hydrogen from ethanol via catalytic oxidative reforming

open access: yesBiofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 1442-1450, November/December 2025.
Abstract This study evaluated a commercial technology for producing low‐ or negative‐carbon hydrogen through ethanol catalytic oxidative reforming, focusing on the life cycle greenhouse gas emissions, or carbon intensity (CI). Various scenarios were analyzed: (a) comparing corn ethanol (first‐generation or Gen1 ethanol) and cellulosic ethanol (second ...
