India announces definition of green hydrogen

The Ministry of New and Renewable Energy (MNRE) has notified the green hydrogen standard for India, in a significant move for the progress of the National Green Hydrogen Mission. Green hydrogen has been de­fined as having a well-to-gate emission (including water treatment, electrolysis, gas purification, drying and compression of hydrogen) of not more than 2 kg of carbon dioxide equivalent per kilogram of hydrogen, taken as an average over the past 12-month period. The standard outlines the emission thresholds to be met in order for the hydrogen produced to be classified as “green”, that is, from renewable sources. The sc­o­pe of the definiti­on encompasses both electrolysis-based and biomass-based hydrogen production methods.
