Hydrogen, particularly green hydrogen produced from water electrolysis using renewable electricity, has received the lion’s share of attention due to its essential role in helping the world reach net-zero emissions by 2050. By comparison, little attention has been paid to biohydrogen (Bio-H2), a type of hydrogen produced from organic waste streams (e.g., agricultural waste) that can potentially yield a carbon-removing (or climate-positive) fuel when coupled with efficient carbon capture and storage. This carbon-negative hydrogen can offer a solution for decarbonizing energy-intensive industrial processes such as iron and steel production. At present, however, the wide deployment of carbon-negative Bio-H2 still faces considerable obstacles.

Please join the Center on Global Energy Policy at Columbia University’s School of International and Public Affairs to discuss key findings from its latest report on hydrogen, The Potential Role of Biohydrogen in the Net-Zero World: The Production and Applications of Carbon-Negative Hydrogen. The report explores the current state of play for Bio-H2 and its potential contribution to decarbonization efforts by examining its production options, carbon footprint, cost, potential applications, and policy options.
