National Green Hydrogen Mission — India’s Net-Zero Fuel Strategy (UPSC Science & Tech)

India has committed to net-zero emissions by 2070. To meet that target while its economy grows, India needs a fuel that can decarbonise hard-to-abate sectors — steel, cement, refineries, heavy trucking, shipping, aviation — where batteries and solar panels cannot easily help. That fuel is green hydrogen. In January 2023, the Union Cabinet approved the National Green Hydrogen Mission with an initial outlay of ₹19,744 crore and a target of producing 5 million metric tonnes (MMT) of green hydrogen per year by 2030.

For UPSC GS III, the mission is a high-probability question theme covering science and technology, energy, environment and Indian economy.

What is Hydrogen

Hydrogen is the most abundant element in the universe but on Earth it exists bound in water and hydrocarbons. It must be extracted and then stored. Its combustion or use in a fuel cell produces only water. Hydrogen is classified by the way it is produced:

• Green hydrogen — Electrolysis of water using 100% renewable electricity. Zero emissions.
• Blue hydrogen — From fossil fuel with carbon capture and storage (CCS).
• Grey hydrogen — From natural gas via steam methane reforming (SMR). 96% of global hydrogen.
• Brown/Black hydrogen — From coal gasification. Most polluting.
• Turquoise hydrogen — Methane pyrolysis producing solid carbon.
• Pink/Yellow hydrogen — Nuclear or grid electricity electrolysis.

National Green Hydrogen Mission 2023

Targets

• 5 MMT per year green hydrogen by 2030 (expandable to 10 MMT).
• 125 GW of renewable energy capacity linked to hydrogen.
• ₹8 lakh crore of cumulative investment.
• 6 lakh jobs generated.
• 50 MMT CO₂ emissions avoided per year.
• Green hydrogen exports — Become a global hub.

Components

• SIGHT — Strategic Interventions for Green Hydrogen Transition with two sub-programmes:
• SIGHT 1 — Incentives for domestic electrolyser manufacturing.
• SIGHT 2 — Incentives for green hydrogen production.
• Pilot projects in steel, mobility (fuel cell buses, trucks), shipping, aviation.
• Hydrogen Hubs — Selected industrial clusters.
• R&D Programme — ₹400 crore for technology readiness.
• Skill development and regulatory framework.

Key Ministries

• Ministry of New and Renewable Energy (MNRE) — Nodal ministry.
• NITI Aayog — Coordination.
• Ministry of Petroleum and Natural Gas — Integration with refineries.
• Ministry of Steel — Industrial use.

Drivers Making Green Hydrogen Viable

• Falling renewable electricity cost — Indian solar PV at ₹2-3/kWh; wind comparable.
• Electrolyser cost decline — 60% since 2010; projected another 50% fall by 2030.
• Fuel cell cost decline — 70% since 2006.
• Net-zero mandates — Paris Agreement, corporate ESG pressure.
• Hard-to-abate demand — Steel (~100 Mt CO₂/year in India), cement, fertilisers.
• Export potential — Japan, Korea, EU want imports.
• Grid balancing — Electrolysers provide flexibility for variable renewables.

Applications

Mobility

• Fuel cell buses (Delhi, Leh), trucks, trains (IRCTC Vande Metro hydrogen prototype 2024), eventually shipping and aviation.
• HCNG blends for existing CNG fleets.

Industry

• Refineries — Decarbonising desulfurisation.
• Ammonia and urea — Fertiliser industry.
• Methanol.
• Direct Reduced Iron (DRI) for green steel.
• Cement — Process heat.

Power

• Long-duration storage (electrolyse when renewables are abundant; run fuel cells or turbines later).
• Hydrogen-ready gas turbines.

Building Heat

• Direct injection into gas grids.

Export

• Liquid hydrogen, ammonia or methanol shipments to Japan, Korea, EU.

Challenges

• Cost — Green hydrogen currently ~$4-6/kg; needs to fall below $2 to compete with grey.
• Storage and transport — Requires high-pressure tanks or cryogenic systems; hydrogen embrittles pipes.
• Safety — Highly flammable, colourless, odourless, invisible flame.
• Purity — Fuel cells need ultra-high purity hydrogen.
• Water requirement — 9 kg of water per kg of hydrogen.
• Infrastructure — Pipelines, filling stations, port export terminals.
• Electrolyser capacity — Current global production ~10 GW/year; India needs several tens of GW by 2030.
• Capital cost — Initial subsidies still needed.

State-Level Initiatives

• Gujarat, Rajasthan, Tamil Nadu, Andhra Pradesh, Karnataka — Early movers with green hydrogen policies.
• Reliance Industries, Adani, Indian Oil, NTPC, Larsen & Toubro, JSW, Tata — Major corporate commitments totalling $100+ billion.
• IISc Bengaluru — Biomass-to-hydrogen tech breakthroughs.

International Partnerships

• Japan, Korea — Offtake agreements.
• EU — RePowerEU targets imports from India.
• Germany — H2Global financing.
• Australia — Joint green hydrogen clusters.
• ISA (International Solar Alliance) — Coordination on renewables for hydrogen.

Way Forward

• Mandates on large hydrogen consumers — Refineries, fertiliser plants, steel plants to use minimum green hydrogen.
• Blend mandates — Initial hydrogen in natural gas grid.
• Port and export hub development — Mundra, Tuticorin, Visakhapatnam.
• Hydrogen valleys — Dedicated industrial clusters.
• Regulatory certainty — Standards, safety norms, certification.
• Public-private partnerships.
• International financing — Green bonds, sovereign green bonds.
