What Happened
- The Ministry of New and Renewable Energy (MNRE) notified quality and emission standards for Green Ammonia and Green Methanol on February 27, 2026, a key step under the National Green Hydrogen Mission.
- Green Ammonia standard: total non-biogenic greenhouse gas emissions must not exceed 0.38 kg CO₂ equivalent per kg of ammonia (NH₃), averaged over the preceding 12 months.
- Green Methanol standard: total non-biogenic greenhouse gas emissions must not exceed 0.44 kg CO₂ equivalent per kg of methanol (CH₃OH), averaged over the preceding 12 months.
- Both standards cover the full production lifecycle — hydrogen generation, synthesis, purification, compression, and storage — and allow renewable energy from grid-banked or stored sources.
- For methanol, CO₂ feedstock may be sourced from biological processes, Direct Air Capture (DAC), or existing industrial sources.
- A separate methodology for measurement, reporting, monitoring, on-site verification, and certification of these standards will be issued by MNRE; prior tenders may continue under original terms.
- The standards are intended to facilitate decarbonisation of fertilisers, shipping, power, and heavy industry, and to position India as a reliable exporter of green fuels.

National Green Hydrogen Mission
The National Green Hydrogen Mission was approved by the Union Cabinet on January 4, 2023, with an initial outlay of ₹19,744 crore. The mission aims to make India a global hub for the production, utilisation, and export of green hydrogen and its derivatives (principally green ammonia and green methanol). Its headline targets include producing 5 million metric tonnes per annum (MMTPA) of green hydrogen by 2030, creating over 6 lakh jobs, and reducing fossil fuel imports by ₹1 lakh crore annually. The mission is implemented by MNRE.
- Target: 5 MMTPA green hydrogen by 2030; installed renewable energy addition of at least 125 GW alongside.
- Strategic Interventions for Green Hydrogen Transition (SIGHT) programme provides financial incentives for domestic electrolyser manufacturing and green hydrogen production.
- Green hydrogen production cost target: below $1 per kg by 2030 (currently ~$4-6 per kg).
- India's first green hydrogen plant was commissioned at NTPC Simhadri (Andhra Pradesh) in 2023.
Connection to this news: The Green Ammonia and Green Methanol standards are the regulatory underpinning for derivatives trade under this mission — without clear emission thresholds, export contracts and certification cannot proceed.
Green Ammonia and Green Methanol: Production and Applications
Green Ammonia is NH₃ produced using green hydrogen (from electrolysis powered by renewable electricity) and nitrogen (from air separation). It is critical for decarbonising the fertiliser sector (ammonia is the base for urea) and is emerging as a zero-carbon shipping fuel. Green Methanol is CH₃OH produced using green hydrogen and captured CO₂. It is a clean chemical feedstock and an alternative marine fuel, increasingly used by global shipping lines to meet International Maritime Organization (IMO) 2050 targets.
- Conventional (grey) ammonia is produced via the Haber-Bosch process using hydrogen from natural gas reforming — the most energy-intensive chemical process globally, responsible for ~1.8% of global CO₂ emissions.
- Grey methanol uses natural gas as both hydrogen source and CO₂ source; green methanol replaces both with green H₂ and captured CO₂.
- India imports ~90% of its urea requirement's feedstock; domestic green ammonia production can reduce this dependency.
- IMO's 2023 Greenhouse Gas Strategy targets net-zero shipping emissions by around 2050, driving demand for green methanol and ammonia as bunker fuels.
Connection to this news: India's newly notified standards define the maximum carbon intensity threshold for calling ammonia or methanol "green" — aligning Indian definitions with emerging global trade and certification norms.
Green Hydrogen: Types and Electrolysis Technology
Hydrogen is classified by production method and associated carbon intensity. Green hydrogen is produced via electrolysis — passing electric current through water (H₂O) to split it into hydrogen (H₂) and oxygen (O₂) — powered entirely by renewable electricity, resulting in near-zero emissions. Grey hydrogen uses steam methane reforming (SMR) of natural gas, emitting ~10 kg CO₂ per kg H₂. Blue hydrogen adds carbon capture and storage (CCS) to SMR. The key technologies for electrolysis are Alkaline Electrolysers (mature, lower cost), Proton Exchange Membrane (PEM) electrolysers (faster response, higher efficiency), and Solid Oxide Electrolysers (high temperature, highest efficiency).
- Electrolysis efficiency has improved significantly; current best systems achieve ~70-80% energy efficiency.
- India's SIGHT programme incentivises domestic electrolyser manufacturing to reduce import dependency.
- Green hydrogen's cost depends largely on the cost of renewable electricity — India's solar power prices (~₹2-2.5/kWh) give it a competitive advantage for green H₂ production.
- MNRE's Green Hydrogen Standard (notified September 2023) already defines the carbon intensity threshold for hydrogen itself (≤2 kg CO₂/kg H₂); the new standards extend this logic to derivatives.
Connection to this news: The new emission thresholds for green ammonia (0.38 kg CO₂/kg NH₃) and green methanol (0.44 kg CO₂/kg CH₃OH) derive from and are consistent with the upstream green hydrogen standard, creating an end-to-end certification framework for India's green fuel ecosystem.
