Promoted as a vital tool to slow climate change, hydrogen (H2) is set to decarbonize long-distance transportation, steel and other industries while utilities plan to blend it with fossil gas for electrical generation. Yet 96% of H2 is currently produced from fossil fuels – mostly gas – resulting in massive carbon pollution. Though industry counters with promises of capturing and storing that CO2 – so called “blue” H2, there’s been no peer-reviewed data available to refute their claims it’s clean. Until now. A new life cycle assessment published in the Journal Energy Science & Engineering by influential scientists Robert Howarth and Mark Z Jacobson finds that instead of being an improvement, blue H2 is at best a “distraction” away from genuinely green solutions. Lead blogger, podcaster and advisor to the Energy Transition, L. Michael Buchsbaum reviews the study and its implications in the first of a series piercing through some of the hydrogen hype.
