India has taken another significant step in advancing the National Green Hydrogen Mission with the notification of new standards for green ammonia and green methanol. Issued by the Ministry of New and Renewable Energy, the framework establishes lifecycle emission limits and eligibility criteria for these fuels when produced using renewable-energy-based hydrogen.
The standards aim to provide regulatory clarity for industry while supporting the development of low-carbon fuels across sectors such as fertilisers, shipping, power generation, and heavy industry.
In a major step toward advancing the National Green Hydrogen Mission, the Government of India has notified Green Ammonia and Green Methanol Standards on February 27, 2026. Issued by the Ministry of New and Renewable Energy (MNRE), the standards establish clear emission thresholds and eligibility conditions for classifying ammonia and methanol as “green” fuels when produced using renewable-energy-based green hydrogen.
The new framework defines the maximum lifecycle greenhouse gas emissions allowed during the production process.
Under the Green Ammonia Standard for India, total non-biogenic greenhouse gas emissions—from green hydrogen production through ammonia synthesis, purification, compression, and on-site storage—must not exceed 0.38 kg of carbon dioxide equivalent per kg of ammonia (kg CO₂ eq/kg NH₃). These emissions are to be calculated as a 12-month rolling average, ensuring that producers maintain consistent low-carbon operations throughout the year.
Similarly, the Green Methanol Standard for India sets a limit of 0.44 kg of carbon dioxide equivalent per kg of methanol (kg CO₂ eq/kg CH₃OH). This threshold accounts for emissions generated during green hydrogen production, methanol synthesis, purification, and on-site storage. Like the ammonia standard, compliance must be measured over a 12-month average period.
The notification also clarifies the eligible sources of carbon dioxide that may be used in green methanol production. These include biogenic sources, Direct Air Capture (DAC), and existing industrial sources. The government has retained flexibility to revise this list in the future, with any changes to apply prospectively and accompanied by suitable grandfathering provisions to protect existing projects.
Another important provision relates to the use of renewable energy. The standards specify that renewable energy can include electricity generated from renewable sources that is either stored in energy storage systems or banked with the grid in accordance with applicable regulatory provisions. This approach provides operational flexibility for developers integrating renewable energy into green hydrogen and derivative fuel production.
Regulatory clarity and industrial impact
The ministry has also indicated that a detailed methodology for measurement, reporting, monitoring, on-site verification, and certification of green ammonia and green methanol will be issued separately. This framework is expected to ensure transparency, traceability, and credibility in verifying that projects meet the prescribed emission thresholds.
To avoid disrupting ongoing procurement processes, the notification states that tenders, bids, or solicitations issued before the standards were notified may continue under their original terms. However, procuring entities may align such tenders with the new standards if mutually agreed by all parties.
The introduction of these standards offers greater regulatory clarity for industry participants, investors, and technology developers engaged in green hydrogen derivatives. By establishing clear low-carbon emission thresholds, the policy is expected to support decarbonisation efforts across sectors including fertilisers, shipping, power generation, and heavy industry.
The move also reinforces India’s ambition to emerge as a major global supplier of green fuels, with domestic developers increasingly targeting export markets for green ammonia and green methanol under the framework of the National Green Hydrogen Mission. The mission, approved by the Union Cabinet of India on January 4, 2023, carries an initial financial outlay of ₹19,744 crore and aims to position India as a global hub for the production, utilisation, and export of green hydrogen and its derivatives.
Green Ammonia and Methanol: Fuels powering a low-carbon future
The transition toward low-carbon industrial systems is increasingly being shaped by emerging clean fuels such as green ammonia and green methanol.
Among these, green ammonia—produced using renewable hydrogen generated through water electrolysis—offers a pathway to reduce emissions at the production stage while continuing to support critical industrial applications. Its growing importance lies in its ability to integrate into existing fertiliser value chains, function as a scalable energy carrier, and enable the transition of hard-to-abate sectors without disrupting ongoing industrial operations.
Green ammonia provides industrial economies with a practical pathway to transition from existing infrastructure toward a low-carbon future. Instead of requiring a complete overhaul of industrial systems, it allows decarbonisation to begin within existing value chains. This is particularly significant for fertiliser production, which globally accounts for nearly 2% of total carbon emissions. Low-carbon ammonia therefore represents a crucial lever for reducing emissions across industrial and agricultural supply chains. Although ammonia’s toxicity demands robust safety and handling frameworks, fertiliser and chemical industries already possess decades of experience managing these risks at scale, providing a strong operational foundation for its expanded use.
The push toward green ammonia is also being influenced by developments in the maritime sector. Demand for cleaner fuels in shipping is encouraging early experimentation with hydrogen and ammonia infrastructure. The hydrogen dispensing system established at the refinery of Indian Oil Corporation Limited in Gujarat reflects how refineries and transport networks are preparing for hydrogen- and ammonia-linked mobility solutions. Internationally, several ports in Europe and East Asia have already announced ammonia-ready bunkering infrastructure, indicating the direction in which global shipping systems are evolving.
Agriculture remains another important application area for green ammonia. By enabling lower-carbon fertiliser production, it supports the shift toward more sustainable agricultural inputs while preserving existing production systems.
Alongside ammonia, green methanol is gaining momentum even faster in certain sectors, particularly global shipping. Unlike ammonia, methanol can be stored and transported at normal temperatures and pressures, and it can be handled within existing marine fuel systems with relatively minor adjustments. These advantages are expected to drive strong adoption by 2030, especially as ports around the world begin building methanol bunkering infrastructure. Several global shipping companies have already ordered methanol-fuelled vessels, highlighting industry confidence in its near-term potential.
Methanol also plays a significant role in the chemical industry. It can be produced by combining renewable hydrogen with captured carbon dioxide or biomass-based carbon, creating a circular carbon pathway that reduces emissions while transforming carbon into a reusable industrial resource. Methanol further supports the production of sustainable aviation fuels through derivative pathways, enhancing its significance as the aviation sector pursues scalable low-carbon fuel solutions.
Conclusion
The Green Ammonia and Green Methanol Standards mark a pivotal step in advancing India’s low-carbon transition under the National Green Hydrogen Mission. By establishing clear emission limits, defining eligible carbon sources, and creating robust monitoring and certification frameworks, the standards provide regulatory certainty for industry and investors. They promote decarbonisation across fertilisers, shipping, power, and chemical sectors while boosting India’s global competitiveness. These initiatives lay the foundation for broader adoption of green hydrogen derivatives, positioning India as a key producer and exporter of sustainable fuels.
