Carbon‐negative hydrogen from ethanol via catalytic oxidative reforming

open access: yesBiofuels, 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 ...

Combining dynamic life cycle assessment and net ecosystem exchange through the framework of biobased materials and products‐life cycle assessment (BBM‐LCA): application to polylactic acid

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biobased products can achieve carbon negativity by storing biogenic carbon in the technosphere through circular loops. Quantifying these benefits requires quantitative assessment tools such as life cycle assessment (LCA). However, the LCA of biobased materials is not straightforward due to the complexity of addressing agroecosystem carbon ...
