Green Hydrogen Policy and National Mission: India’s Net-Zero Fuel and UPSC Notes (UPSC Environment)

Study Notes · Environment & Ecology · General Studies · GS III · Science & Tech

UPSC guide to India's Green Hydrogen Policy and National Green Hydrogen Mission: electrolysers, types of hydrogen, incentives, challenges and global hydrogen economy.

Green hydrogen is hydrogen produced by splitting water with electricity from renewable sources. It emits no carbon dioxide when made and no carbon dioxide when used, making it the only zero-carbon fuel that is also energy-dense enough to replace fossil fuels in hard-to-electrify sectors such as steel, fertiliser, refining, long-haul shipping and heavy-duty transport. India’s Green Hydrogen Policy of 2022 and the National Green Hydrogen Mission of 2023 set the country on course to become a global hub for green hydrogen production. The topic is central to UPSC GS Paper III (energy, environment, science and technology).

Why green hydrogen

Hydrogen is the most abundant element in the universe, but it does not occur in pure form on Earth. It must be produced from hydrogen-bearing compounds like water or hydrocarbons.

The International Renewable Energy Agency (IRENA) projects that hydrogen will make up 12 percent of the global energy mix by 2050, with two-thirds sourced from water electrolysis powered by renewables.

India's hydrogen advantage

Types of hydrogen by colour

Green Hydrogen Policy, 2022

The Ministry of Power notified the Green Hydrogen/Green Ammonia Policy in February 2022 to promote domestic production capacity.

Incentives for production

National Green Hydrogen Mission, 2023

Approved by the Cabinet in January 2023 with an outlay of Rs 19,744 crore up to 2029-30.

Challenges

Technology

Compressing or liquefying hydrogen is difficult. Liquid hydrogen must be stored at minus 253 C, far colder than LNG at minus 163 C. This makes distribution and storage infrastructure expensive.

Cost

The production cost of green hydrogen is currently about USD 4 to 5 per kg in India. To be competitive with grey hydrogen (around USD 1.5 to 2 per kg), costs must fall substantially. IRENA projects that in countries with excellent renewable resources, green hydrogen can reach USD 1.5 per kg by 2030 with aggressive scaling.

Electrolyser manufacturing

Global electrolyser capacity is about 0.3 GW per year, while net-zero scenarios require almost 5,000 GW by 2050. India has no significant domestic electrolyser manufacturing ecosystem yet.

Fuel cell cost

Hydrogen fuel cells for cars and trucks are still far more expensive than batteries or internal combustion engines per mile.

Refuelling infrastructure

Hydrogen refuelling stations are scarce. India had under 10 stations in early 2025, against the hundreds needed for heavy-duty transport.

Water use

Electrolysis consumes about 9 litres of water per kg of hydrogen. Siting green hydrogen plants in water-stressed regions raises trade-offs.

Safety

Hydrogen is highly flammable and has a wide flammability range. Standards, certification and safety training are nascent.

UPSC Relevance

Prelims focus

Mains focus (GS III)

Typical question framings examine the role of green hydrogen in India's energy transition, the cost and technology challenges, the strategic implications for energy independence, and the industrial decarbonisation benefits. Strong answers integrate the 2022 policy and 2023 Mission, reference international comparisons with the EU Hydrogen Strategy and US Inflation Reduction Act, and address trade-offs (water, cost, safety).

Linkages

Green hydrogen connects to SDG 7 (affordable clean energy), SDG 13 (climate action), India's NDCs post-COP29, the 500 GW non-fossil capacity target, the Paris Agreement, the Energy Conservation Amendment Act 2022, the Indian Carbon Market, and the International Solar Alliance for export partnerships.
