Carbon‐negative hydrogen from ethanol via catalytic oxidative reforming

Biofuels, Bioproducts and Biorefining, EarlyView.
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 ...
