Hydrogen could play a major role in emissions reduction by 2030 thanks to the scaling up of low-carbon "green hydrogen" production, the non-profit Rocky Mountain Institute (RMI) explained last week in a blog post.
The carbon footprint of fuel-cell vehicles can vary dramatically based on how the hydrogen they use is produced. Green hydrogen is produced through electrolysis, with electricity generated from renewable sources, to minimize carbon emissions. There should be plenty of electrolysis capacity online by the end of the decade, RMI predicts.
