The government on Saturday unveiled Green Hydrogen standards and included electrolysis and biomass-based methods in its definition. The standards issued by the ministry outline the emission threshold that must be met for hydrogen produced to be classified as ‘Green’, i.e., from renewable sources.

The scope of the definition encompasses both electrolysis-based and biomass-based hydrogen production methods, it stated.

After discussions with multiple stakeholders, the ministry has decided to define Green Hydrogen as having a well-to-gate emission (including water treatment, electrolysis, gas purification, drying and compression of hydrogen) of not more than 2 kg CO2 equivalent/kg H2.

The notification specifies that a detailed methodology for measurement, reporting, monitoring, on-site verification, and certification of green hydrogen shall be specified.
