Green Ammonia and Green Methanol
Why in news?
Recently green ammonia and green methanol under the National Green Hydrogen Mission, fixing emission thresholds and a certification framework for these fuels.
About
- The Ministry of New and Renewable Energy (MNRE) has issued standards defining what will be called “Green Ammonia” and “Green Methanol” in India.
- These standards set lifecycle greenhouse gas (GHG) emission limits (per kg of product) and conditions for production using green hydrogen from renewable energy.
- Notifications were issued on 27 February 2026 as part of implementation of the National Green Hydrogen Mission.
- A detailed methodology for measurement, reporting, monitoring, on‑site verification and certification will be issued separately to enable trading and use of these fuels.
- Government expects these norms to guide industry and investors and to accelerate decarbonisation in fertilisers, shipping, power and heavy industries.
Green hydrogen
- Green hydrogen is hydrogen produced using electricity from renewable sources (solar, wind, etc.) via water electrolysis, with very low lifecycle GHG emissions.
- It is the feedstock for both green ammonia and green methanol, replacing hydrogen from fossil fuels like natural gas or coal.
Green ammonia
- Ammonia (NH₃) is normally produced from hydrogen and nitrogen, traditionally using hydrogen from natural gas (high emissions).​
- Green ammonia is ammonia produced using green hydrogen and atmospheric nitrogen, powered by renewable electricity, resulting in very low or near‑zero lifecycle carbon emissions.
- Major uses- nitrogenous fertilisers, Energy carrier and hydrogen storage medium, carbon‑neutral fuel
Green methanol
- Methanol (CH₃OH) is usually made from hydrogen and a carbon source (often natural gas based syngas), which is emission‑intensive.​
- Green methanol is produced using green hydrogen plus a renewable or recycled carbon source (captured CO₂ or biomass‑based carbon), with energy from renewables, thus greatly lowering lifecycle emissions.
- Major uses- Marine fuel, Chemical industry, Other energy uses
Key features of India’s new standards
- Definition: “Green Ammonia” means ammonia produced exclusively using green hydrogen; “Green Methanol” means methanol produced using green hydrogen.​
- Emission caps: MNRE has notified lifecycle emission limits around 0.38 kg CO₂‑equivalent per kg of green ammonia and 0.44 kg CO₂‑equivalent per kg of green methanol to qualify as green (values as reported by sectoral news sources).​
- Renewable electricity: Power used in production must be from renewable sources; it can include electricity stored in energy storage systems or banked with the grid under applicable regulations.
- Certification framework: Standards will be backed by a formal system for measurement, reporting, monitoring, on‑site verification and certification, which MNRE will detail separately.
- Policy objective: These standards operationalise part of the National Green Hydrogen Mission and aim to enable domestic use and exports of certified green ammonia and methanol.
