Meaning

The National Green Hydrogen Mission (NGHM) is a central government programme, launched in January 2023 with an outlay of ₹19,744 crore and run by the MNRE (Ministry of New and Renewable Energy). Its aim is to make and use 5 million tonnes (MMT) of green hydrogen a year by 2030, supported by about 125 GW of new renewable power capacity linked to it [1].

It matters because some sectors cannot be cleaned up with electricity alone: refining, fertiliser, steel and shipping. Green hydrogen can cut their emissions. It can also reduce India's imports of gas and ammonia.

Explanation

How green hydrogen is made (cause → process → result)

  • Hydrogen is both a fuel and an industrial raw material. When it burns, or is used in a fuel cell, it gives out only water. Any pollution comes from the way it is made.
  • Step 1 (cause): renewable electricity from solar or wind is passed through water in an electrolyser (a machine that uses electric current to split water).
  • Step 2 (process): this is called electrolysis. Water (H₂O) splits into hydrogen gas at one electrode and oxygen gas at the other.
  • Step 3 (result): the hydrogen is almost carbon-free, because no fossil fuel is burnt at any step.
  • Green Hydrogen Standard (2023, MNRE): in India, hydrogen counts as "green" only if its total emissions are not more than 2 kg CO₂ per kg of H₂. This limit covers every step:
  • water treatment;
  • electrolysis;
  • gas purification;
  • drying;
  • compression.

What the Mission contains

  • Targets for 2030:
  • 5 MMT of green hydrogen a year;
  • about 125 GW of linked renewable capacity;
  • expected gains: about ₹8 lakh crore of investment, about 6 lakh jobs and about ₹1 lakh crore saved on fossil fuel imports [1].

  • SIGHT (Strategic Interventions for Green Hydrogen Transition): the Mission's money-support part. It funds two things:

  • making electrolysers in India;
  • producing green hydrogen.

  • Research and development:

  • A ₹400 crore R&D scheme supports 23 projects on hydrogen production, storage, safety and industrial use.
  • In 2025 a ₹100 crore call for proposals was opened for start-ups, with up to ₹5 crore for each project [4].

  • Green Hydrogen Hubs (recognised October 2025): these are places where hydrogen will be made, used and exported. All three are major ports [1][2].

Who will use it (demand sectors)

  • Refineries: green hydrogen replaces the grey hydrogen now used to process oil.
  • Fertiliser plants:
  • green hydrogen is turned into green ammonia;
  • green ammonia is then used to make urea and other fertilisers.

  • Steel:

  • hydrogen can take the place of coking coal in removing oxygen from iron ore;
  • steel made this way is called green steel.

  • Shipping: ships can run on fuels such as green ammonia and green methanol.

What it needs to work

  • Cheap renewable power: green hydrogen still costs more than grey hydrogen. The cost comes down as solar power and electrolysers get cheaper.
  • Water: electrolysis needs water. But the sunniest places, which are best for solar power, are often dry.
  • Electrolyser factories: India needs to make electrolysers at home. This is why SIGHT funds their manufacture.

Where it occurs

  • Who runs it and since when: MNRE, from January 2023, across all of India.
  • Green Hydrogen Hubs (October 2025) [1][2]:
Port (official name) State Water body Why this place
Deendayal Port, Kandla Gujarat Gulf of Kachchh, Arabian Sea West coast; close to the solar and wind belt of Gujarat and Rajasthan
Paradip Port Odisha Bay of Bengal, Mahanadi delta East coast; near the refinery and steel belt
V.O. Chidambaranar Port, Thoothukudi (Tuticorin) Tamil Nadu Gulf of Mannar South-east coast; close to Tamil Nadu's wind farms
  • Progress at Kandla:
  • In 2025 a megawatt-scale, made-in-India green hydrogen plant started working. It cost about ₹13 crore and can make nearly 140 tonnes a year [2][3].
  • A ₹42 crore, 750 m³ green methanol bunkering and refuelling facility is being built. Bunkering means filling ships with fuel. It will support a Coastal Green Shipping Corridor between Kandla and Tuticorin [2].

  • Where the demand is: refineries and fertiliser plants across India, which today mostly use grey hydrogen. Also the steel belt near Paradip.

Don't confuse with

  • Grey hydrogen: made from natural gas (methane) by steam reforming, and it releases a lot of CO₂. Green hydrogen is made from water by electrolysis using renewable power. Most hydrogen used in Indian refineries and fertiliser plants today is grey.
  • Green Energy Corridor (GEC, 2015): a power transmission network that carries renewable electricity from states such as Rajasthan, Gujarat, Tamil Nadu and Karnataka into the national grid. It moves electricity. It does not make hydrogen.
  • SIGHT vs NGHM: NGHM is the whole Mission. SIGHT is only its money-support part, for making electrolysers and producing green hydrogen.
  • Green ammonia / green methanol: these are fuels or products made from green hydrogen. They are not other names for it. Green methanol is the fuel for the Kandla bunkering facility [2].

Prelims Hooks

  • NGHM: January 2023; ₹19,744 crore; MNRE; target of 5 MMT a year by 2030 with about 125 GW of linked renewables [1].
  • SIGHT = Strategic Interventions for Green Hydrogen Transition. It funds electrolyser manufacture and green hydrogen production.
  • India's Green Hydrogen Standard (2023): at most 2 kg CO₂ per kg H₂, counting water treatment, electrolysis, purification, drying and compression.
  • Hub port–state pairs (October 2025): Deendayal/Kandla – Gujarat; Paradip – Odisha; V.O. Chidambaranar/Thoothukudi – Tamil Nadu [1]. Trap: Kandla is on the Gulf of Kachchh, not the Gulf of Khambhat.
  • Kandla: made-in-India megawatt-scale plant of about 140 tonnes a year (2025) [2][3]. It also has a green methanol bunkering facility for the Kandla–Tuticorin Coastal Green Shipping Corridor [2].
  • R&D: ₹400 crore scheme with 23 projects, plus a ₹100 crore start-up call in 2025 (up to ₹5 crore per project) [4].

Mains Points

  • Green hydrogen as an industrial strategy (GS-III):
  • It cuts emissions in "hard-to-abate" sectors (sectors that electricity alone cannot clean up): refining, fertiliser, steel and shipping.
  • It lowers gas and ammonia imports, saving about ₹1 lakh crore by 2030 [1].
  • The port hubs at Kandla, Paradip and Thoothukudi bring production, use and export together on the coast [1][2].

  • Geography of where hubs are placed:

  • Each hub sits near a renewable or industrial base: the Gujarat–Rajasthan solar and wind belt for Kandla, the refinery and steel belt for Paradip, and Tamil Nadu's wind farms for Thoothukudi.
  • Being at a port makes export and ship refuelling easy, which is the idea behind the Kandla–Tuticorin green shipping corridor [2].

  • Challenges and responses:

  • High cost: green hydrogen is still costlier than grey hydrogen. The response is SIGHT support, plus cheaper solar power and electrolysers over time.
  • Water stress: the best solar regions are often dry, but electrolysis needs water.
  • Manufacturing gap: India has limited capacity to make electrolysers. The response is SIGHT funding for home manufacture and the ₹400 crore R&D push [4].
