India’s green ammonia India aims to produce 5 million tonnes of green ammonia by 2030 under the National Green Hydrogen Mission to reduce imports and enhance energy self-reliance. India has also signed agreements for 724 lakh metric tonnes of green ammonia production for domestic use, indicating large-scale expansion plans. Ammonia is critical for India’s agriculture sector as it is a key input for fertiliser production, especially Di-Ammonium Phosphate (DAP), linking energy security with food security. India currently imports over 70% of its 30 million tonnes annual ammonia requirement, mainly as grey ammonia from countries like Oman, Saudi Arabia, Qatar and Bahrain. Grey ammonia production is highly carbon intensive, emitting 1.9–2.6 tonnes of CO₂ per tonne of ammonia produced. India’s grey ammonia production contributes about 25–43 million tonnes of CO₂ annually, accounting for 5–10% of global ammonia-related emissions and about 1.2–1.8% of total global greenhouse gas emissions. Transition to green ammonia aligns with India’s commitments under the Paris Agreement by reducing emissions through renewable hydrogen-based production.
