The National Green Hydrogen Mission is India’s flagship plan to turn the country into a global hub for the production, use and export of green hydrogen and its derivatives, such as green ammonia and green methanol. Approved by the Union Cabinet in January 2023, it brings together policy support, financial incentives, research and industrial planning under a single national umbrella, with the Ministry of New and Renewable Energy (MNRE) acting as the nodal ministry.
The idea behind the mission is simple but ambitious. Hydrogen can burn or react without releasing carbon dioxide, and when it is made by splitting water with renewable electricity, the whole chain is almost carbon-free. If India can make this fuel cheaply and at scale, it can clean up industries that are very hard to decarbonise, reduce its dependence on imported fossil fuels, and even sell clean molecules to the world. This explainer covers what green hydrogen is, why it matters, what the mission aims to do, and what stands in the way.

What Is Green Hydrogen?
Hydrogen is the lightest and most abundant element in the universe, but on Earth it rarely exists on its own. It is locked inside water, natural gas, coal and living matter, and it has to be separated before it can be used. How that separation is done decides whether the hydrogen is clean or dirty.
The electrolysis process
Green hydrogen is produced by electrolysis. An electrolyser passes an electric current through water and splits it into hydrogen and oxygen. If the electricity comes from solar, wind or other renewable sources, the hydrogen carries almost no carbon footprint. The only by-product is oxygen, and when the hydrogen is later used in a fuel cell or burned, it gives back water.
Why the source of electricity matters
Electrolysis powered by a coal-heavy grid would simply shift the emissions elsewhere. That is why the mission ties hydrogen production so closely to new renewable capacity. In 2023 India notified a standard defining green hydrogen by an emissions threshold, so that only hydrogen with a very low carbon intensity over its production process can carry the label.
Derivatives of hydrogen
Hydrogen is a gas that is difficult to store and move. It is therefore often converted into carriers that are easier to handle:
- Green ammonia, made by combining green hydrogen with nitrogen, used for fertilisers and increasingly as a shipping fuel.
- Green methanol, used as a chemical feedstock and a marine fuel.
- Synthetic fuels, which can substitute for kerosene or diesel in certain uses.
The Hydrogen Colour Spectrum
Hydrogen itself is colourless, but the industry uses colours as shorthand for how it is made. The colour tells you how clean it is. At present, almost all hydrogen used in India, mostly in refineries and fertiliser plants, is the grey kind.
| Colour | How it is made | Climate impact |
|---|---|---|
| Grey | Steam reforming of natural gas (or similar fossil feedstocks), with the carbon dioxide released | High emissions; the current industrial norm |
| Black / Brown | Gasification of coal or lignite | Highest emissions |
| Blue | Same as grey, but the carbon dioxide is captured and stored | Lower emissions, but depends on capture efficiency and methane leaks |
| Turquoise | Methane splitting (pyrolysis) that produces solid carbon rather than gas | Potentially low, still emerging |
| Pink | Electrolysis powered by nuclear electricity | Low emissions |
| Green | Electrolysis of water using renewable electricity | Near zero carbon |
The colours are informal rather than legal categories, and different countries draw the lines slightly differently. What matters for the mission is the shift from grey to green: replacing hydrogen that is made from fossil fuels with hydrogen made from water and sunshine or wind.
Why Green Hydrogen Matters for India
Electricity from solar and wind can already replace coal in power plants, and batteries can electrify cars and buses. But a number of industrial processes need either very high heat, a chemical ingredient, or a fuel that is light and energy dense. For these, direct electrification is difficult, and green hydrogen offers a cleaner alternative.
The hard-to-abate sectors
Often called “hard-to-abate” sectors, these industries account for a large share of industrial emissions in any developing economy. Hydrogen and its derivatives can help in several of them:
- Fertilisers: India is a major consumer of urea and other nitrogen fertilisers, and ammonia is produced today using grey hydrogen from natural gas.
- Oil refining: Refineries use hydrogen to remove sulphur and upgrade fuels, and can switch part of it to green sources.
- Steel: Hydrogen can replace coking coal or natural gas in the reduction of iron ore, leading to so-called green steel.
- Cement and chemicals: Hydrogen can supply clean process heat and feedstock where electricity alone is not enough.
- Transport and shipping: Fuel cells and hydrogen-based fuels suit heavy trucks, long-distance buses, ships and, eventually, aviation.
Storage and flexibility
Renewable power is variable. When solar output peaks at noon, there may be more electricity than the grid can use. Producing hydrogen from this surplus, and storing it, turns an intermittent resource into a dispatchable one. In this way, hydrogen can act as a form of long-duration energy storage.
Energy Security and the Import Bill
India imports a large majority of its crude oil and a significant share of its natural gas. These purchases make the economy sensitive to global price shocks and affect the trade balance and the value of the rupee. Domestic green hydrogen, made from sunlight, wind and water found within the country, offers a way to replace some of this imported fossil energy with locally produced fuel.
The mission document highlights this as one of its key benefits, estimating savings of over a lakh of crore rupees in fossil-fuel imports once the target capacity is reached. Such figures are projections and depend on how quickly costs fall and demand develops, but the strategic logic is clear: energy produced inside the country is less exposed to price swings and supply disruptions abroad.
Energy security is also tied to technology. India today relies heavily on imports for many clean-energy components, so the mission explicitly aims to build domestic manufacturing of electrolysers, the central machines in the hydrogen economy. Owning the manufacturing base is seen as essential to avoiding a new kind of import dependence.
Goals of the National Green Hydrogen Mission
The mission sets out a set of linked objectives that together are meant to create a complete value chain, from renewable power to electrolysers to end users. As stated at the time of approval, the main targets for 2030 were as follows.
| Goal | Stated target (approximate) |
|---|---|
| Green hydrogen production | About 5 million tonnes per year, expandable with demand |
| New renewable energy capacity | Around 125 GW added to support production |
| Investment | Over eight lakh crore rupees in total, as envisaged |
| Jobs | Several lakh jobs created across the value chain |
| Fossil-fuel import savings | More than a lakh crore rupees cumulatively |
| Emissions | Cut of nearly 50 million tonnes of annual greenhouse-gas emissions |
These numbers are official aspirations, not guarantees. They are best read as a direction of travel. The initial outlay approved for the mission was in the region of Rs 19,700 crore, of which the largest share was allotted to the SIGHT incentive programme.
The SIGHT Programme
SIGHT stands for Strategic Interventions for Green Hydrogen Transition. It is the financial engine of the mission and is designed to make the early, expensive stage of the industry commercially viable.
Two incentive streams
- Electrolyser manufacturing: Incentives for companies that build electrolysers in India, so that the country develops a domestic supply chain instead of importing them.
- Green hydrogen production: Incentives for producers who make green hydrogen or green ammonia and sell it, reducing the price gap with fossil-based hydrogen.
How the support works
Support is generally awarded through competitive bidding, which encourages companies to offer the lowest possible incentive and helps discover real market prices. The incentive is designed to taper over time, on the expectation that costs will fall as the industry scales up and learns by doing.
Why incentives are needed
Without support, early projects would struggle to compete with cheap grey hydrogen. By guaranteeing a market for a defined volume, SIGHT gives investors and equipment makers the confidence to build large factories and plants, which is the main route to lower costs.
Pilot Projects, Hubs and Enabling Measures
Besides incentives, the mission has several other components that are meant to create real-world demand and the supporting ecosystem.
Pilot projects
Pilot projects test hydrogen in sectors where its use is still new. These include steel making, where hydrogen is used to reduce iron ore, mobility, where hydrogen-fuelled buses and trucks are tried out, and shipping, where hydrogen-based fuels are being explored for vessels and port operations.
Green hydrogen hubs
The mission calls for large-scale production and use clusters, known as green hydrogen hubs, in regions with excellent renewable resources, existing industry and port access. Locating electrolysers, renewable plants, storage, pipelines and customers close to one another reduces transport costs and speeds up learning. Coastal states with major ports, such as Gujarat, Odisha and Tamil Nadu, have been widely discussed as natural candidates.
Standards, regulation and skills
- Developing national standards and certification for green hydrogen and for equipment.
- Streamlining regulation, safety norms and approvals.
- Supporting research and development through a public-private framework.
- Training a workforce for design, operation and maintenance.
Advantages India Brings to the Race
India is not the only country with ambitions in hydrogen, but it starts with a set of structural advantages that make the green variety particularly promising.
Abundant, low-cost renewables
The cost of electricity is the largest component of the cost of green hydrogen. India has high solar irradiation across much of the country, strong wind resources in certain regions, and some of the world’s lowest tariffs for solar power. Over the last decade, India has also built a large renewable energy sector and expertise in running competitive auctions.
Large domestic demand
Because India already uses large quantities of grey hydrogen in fertilisers and refining, there is a ready market for green hydrogen to replace it. This “anchor demand” lowers the risk for early investors, since buyers already exist.
Industrial and geographical strengths
- A long coastline with ports that can serve as export gateways.
- A large engineering and manufacturing base.
- Strong demand growth in steel, chemicals and transport, which allows new plants to be built clean from the start.
- Availability of land for utility-scale solar and wind farms.
The Challenges Ahead
For all the optimism, green hydrogen remains an early-stage industry, and several hurdles must be cleared before the mission’s targets can be met.
Cost gap with grey hydrogen
Green hydrogen is currently more expensive than grey hydrogen, which benefits from mature technology and cheap natural gas. Closing this gap depends on cheaper renewable power, cheaper electrolysers and larger scale.
Electrolyser technology and supply chain
Electrolysers are expensive, and their efficiency, lifetime and the materials they use, such as certain metals and membranes, all affect the final cost. Building a competitive domestic manufacturing sector from a very small base will take time.
Resources, storage and transport
- Renewable power: Producing millions of tonnes of hydrogen needs a very large amount of additional solar and wind capacity, along with transmission lines.
- Water: Each kilogram of hydrogen needs roughly nine litres of pure water in theory, and more in practice, which matters in water-stressed regions. Seawater desalination is one option for coastal plants.
- Storage and transport: Hydrogen is very light and leaks easily, so compressing, liquefying, piping or converting it into ammonia needs dedicated infrastructure and strict safety practices.
- Demand creation: Industries will switch only when green hydrogen is competitively priced or when regulation and carbon markets reward them for doing so.
Links to Net-Zero 2070 and the 500 GW Goal
The mission does not stand alone. At the COP26 climate summit in Glasgow in 2021, India announced that it would aim to reach net-zero emissions by 2070 and to install 500 GW of non-fossil electricity capacity by 2030. Green hydrogen is one of the tools meant to help deliver both.
Electricity alone can cover only part of the energy system. Industry, heavy transport and chemicals need clean molecules in addition to clean electrons, and green hydrogen and its derivatives provide them. In turn, hydrogen production creates a large new source of demand for renewable electricity, which supports further expansion of solar and wind capacity beyond what the power sector alone would need.
This link makes the mission as much an industrial strategy as a climate one. It aims to ensure that as the economy grows, the extra energy comes from cleaner sources, while the country builds technology and manufacturing capabilities for the long run.
Export Ambitions: Japan, Korea and Europe
India does not want to use all its green hydrogen at home. The mission explicitly seeks to position the country as an export hub, supplying clean fuel to economies that cannot produce enough renewable energy themselves.
- Japan and South Korea: Both have limited land and renewable resources, and both have set out national hydrogen strategies that rely partly on imports.
- Europe: The European Union has set its own hydrogen targets and is introducing a carbon border adjustment mechanism, which gives clean industrial products an advantage in that market.
Because hydrogen is hard to ship, exports are likely to take the form of green ammonia, green methanol or green steel, rather than hydrogen gas. Long-term supply agreements, port infrastructure and internationally recognised certification will all be important. India has also held discussions on hydrogen cooperation with several partners, and is expected to build on these as the market matures.
Conclusion
The National Green Hydrogen Mission represents a bet that India can combine its renewable energy strengths with its industrial base to create a new clean-fuel sector. The potential rewards are considerable: lower emissions in hard-to-abate industries, greater energy security, new manufacturing and jobs, and a foothold in a future global trade in clean molecules.
The challenges are equally real. Costs must fall, infrastructure must be built, and demand must develop in step with supply. The mission’s targets are best understood as ambitious goals that will be tested over the coming years. Whether India becomes a leading hydrogen hub will depend on how well policy, technology and investment come together. (Last updated: 1 October 2026)
