The Ministry of New and Renewable Energy (MNRE) has released a standard dictating the emission criteria for hydrogen to be classified as ‘green’ in India. The Green Hydrogen Standard for India outlines that green hydrogen must be generated through electrolysis-based and biomass-based methods using renewable sources. This definition of green hydrogen also encompasses renewable energy produced from such sources, which can be stored in energy storage systems or deposited into the grid as per existing regulations.
The Ministry has defined green hydrogen to have a well-to-gate emission, including purification, drying, and compression of hydrogen, of not more than 2 kg of carbon dioxide equivalent per kg of hydrogen, taken as an average over the last 12 months. The emission limits apply to electrolysis-based production methods, including water treatment, electrolysis, and biomass-based methods, including biomass processing, heat/steam generation, and conversion of biomass to hydrogen. The Ministry also plans to introduce a detailed methodology for measurement, reporting, monitoring, on-site verification, and certification of green hydrogen and its derivates soon.
The Ministry’s definition of green hydrogen includes a maximum well-to-gate emission of 2 kg of carbon dioxide equivalent per kg of hydrogen, averaged over the previous year, encompassing purification, drying, and compression. These emission limits are applicable to both electrolysis-based and biomass-based production methods, covering processes like water treatment, electrolysis, biomass processing, heat/steam generation, and biomass-to-hydrogen conversion. Additionally, the Ministry intends to soon introduce a comprehensive approach for measuring, reporting, monitoring, on-site verification, and certification of green hydrogen and its derivatives.
The Bureau of Energy Efficiency, operating under the Ministry of Power, has been designated as the central authority responsible for accrediting agencies to oversee the monitoring, verification, and certification of green hydrogen projects. This notification is expected to provide greater clarity for industry stakeholders.
Earlier this year, India sanctioned the National Green Hydrogen Mission, aimed at promoting the creation, production, utilization, and export of green hydrogen, with an initial budget of ₹197.44 billion (~$2.38 billion). In June, the MNRE released a framework detailing incentive initiative for domestic electrolyzer manufacturing and green hydrogen production, with a combined budget of ₹174.9 billion (~$2.1 billion).
Recently, the Solar Energy Corporation of India invited bids from green hydrogen producers to establish facilities producing 450,000 metric tons per annum across India under the Strategic Interventions for Green Hydrogen Transition program (Mode-I, Tranche-I).
