Green hydrogen is getting a lot of attention in India. And if you are looking for green hydrogen stocks, the space is still quite small.
There are hardly any listed companies in India that can be called pure green hydrogen plays. Most of the stocks connected to this theme belong to bigger businesses that already operate in areas like energy, power, gas, engineering, or industrial manufacturing. Green hydrogen is only one part of their larger business for now.
That is why this theme needs a bit more caution while reading it. Some companies are working on electrolysers. Some are planning green ammonia projects. Some are setting up pilot plants. And some are still only talking about future intent.
Below is a breakdown of listed Indian companies with green hydrogen exposure in 2026. We explain where they fit in the value chain, and highlight the key points readers should understand before assessing the space.
Market Context: Why Green Hydrogen Matters for India
An electrolyser runs electricity through water and splits it into hydrogen and oxygen. That hydrogen gets used as fuel or as a raw material in fertiliser plants, steel mills, and oil refineries. These are industries that can’t decarbonise simply by switching to electric motors, which is why hydrogen keeps getting attention.
India’s hydrogen today mostly comes from natural gas, which is neither clean nor cheap in the long run. The National Green Hydrogen Mission, launched in 2023, wants to fix that. They set a target of 5 million tonnes of annual green hydrogen production by 2030, with an estimated ₹8 lakh crore in investment needed to build the infrastructure around it.
Whether those targets are met on time is a separate question. What’s already visible is that large Indian conglomerates are committing real capital to this theme, and that’s what creates equity exposure worth tracking.

Best Green Hydrogen Stocks in India
Below is a green hydrogen stocks list of companies actively investing in hydrogen production, infrastructure, or ecosystem development.
1. NTPC Limited
NTPC runs more installed power capacity than any other utility in India, and for most of its history that meant coal. They are currently developing the Pudimadaka Green Hydrogen Hub in Andhra Pradesh, a ₹1.85 lakh crore project. The goal is to produce 1,500 tonnes per day (TPD) of green hydrogen, primarily for conversion into green ammonia for the export market.
Strengths
Largest installed power capacity in India
Strong balance sheet
Proven capability in large-scale renewable energy integration
Risks
Execution speed
Heavy capex requirements
Reliance is building a fully integrated “New Energy" ecosystem in Jamnagar. The electrolyser giga-factory is expected to hit 3 GW of annual manufacturing capacity by late 2026. Captive demand from their own refinery reduces the commercial risk that other hydrogen producers face. Strengths Massive capital allocation Technology partnership with Nel Hydrogen, Norway Access to a 5.5 lakh-acre solar land bank in Kutch, Gujarat Risks Execution complexity Exposure to global price swings (iridium and nickel) Adani Group is building one of the world’s largest renewable energy platforms. Hydrogen production requires cheap renewable electricity, something Adani Green Energy specialises in. Strengths ₹30,000 crore ($3.6B) CAPEX for 5 GW expansion Lowest renewable energy generation cost Vertical integration through Adani New Industries (ANIL) for hardware Risks High debt-to-equity ratio Regulatory and geopolitical scrutiny IOC’s refineries already consume hydrogen, currently grey. Switching to green at Mathura and Panipat means the demand side is solved before the first plant is commissioned. Strengths Strategic transition of Mathura and Panipat refineries into green hubs Ready land and infrastructure at refinery sites Slower commissioning cycles Refining margins tied to crude volatility GAIL operates India’s largest natural gas pipeline network. Hydrogen may eventually be transported through modified gas pipelines. They are the infrastructure provider for hydrogen transport. Strengths Monopoly-like control over India’s 15,000 km natural gas pipeline grid Operational 10 MW green hydrogen plant in MP Expertise in high-pressure gas storage & transmission logistics Risks High costs of converting existing infrastructure to handle pure hydrogen Technical limits on hydrogen blending percentages in older pipelines JSW Energy is the first Indian company to supply green hydrogen for commercial steel production. They are now expanding aggressively into renewables and hydrogen. The company plans to integrate hydrogen into its industrial ecosystem including steel production. Strengths Commissioned 3,800 TPA green hydrogen plant supplying JSW Steel 6,800 TPA allocation under SIGHT subsidy scheme Risks Limited revenue diversification Large scale project risk BPCL is adding 5 MW electrolysers at its Kochi and Bina refineries. Hydrogen-powered buses and fuel stations could become a long-term opportunity. Captive demand exists from day one. Strengths Land available at refinery sites for expansion Large fuel station network for future distribution Early work on hydrogen fuel cells for trucking Risks Smaller scale than RIL and NTPC Rising competition in green fuels Power Grid will play a critical role in transmitting renewable electricity needed for hydrogen production. Without strong grid infrastructure, hydrogen scaling becomes difficult. Strengths ₹40,000 crore Green Energy Corridor project Record of high grid availability and reliability Near-monopoly in interstate power transmission Risks Regulated profit margins Land acquisition for new transmission lines NGEL is NTPC’s listed renewable arm. It has 4.9 GW of operational capacity as of early 2026 and leads NTPC's green ammonia export projects. Revenue grew 10x between FY23 and FY24. Finance costs and depreciation are still a drag on net margins. Strengths Access to parent's land banks and project pipeline Focus on round-the-clock renewable power supply Valuation premium high High depreciation and finance costs SJVN runs India’s first multi-purpose green hydrogen pilot in Himachal Pradesh. They are now diversifying into solar, wind, and green hydrogen projects. Their 1.31 MW solar plant powers a 20Nm³/hr electrolyser producing 14 kg of hydrogen daily.

Factors to Consider Before You Invest in Green Hydrogen Companies
1. Government Policy Support
Every company in this list is building on the assumption that SIGHT subsidies and National Green Hydrogen Mission incentives remain intact. Policy reversals or delayed disbursements directly affect project economics.
2. Balance Sheet
Hydrogen projects run long before they generate revenue. Companies carrying high debt going into this cycle have less room for timeline slippage.
3. Renewable Power Access
Production cost is tied to electricity cost. Companies generating their own solar or wind power at low cost will always underprice those buying from the grid.
4. Global Competition
Australia, Saudi Arabia, and the EU are all targeting the same export markets. India’s ability to compete on price will decide how much of that opportunity is actually within reach.
Conclusion
Green hydrogen in India is pre-revenue for most listed companies, it is still an emerging industry.
The companies best placed are those that don’t need hydrogen to work to survive but are building the infrastructure now so they benefit when it does. Execution track record, balance sheet strength, and renewable capacity are the three things worth watching. Everything else is narrative. For long-term investors, the opportunity is real, but so are the risks.
