Green hydrogen is emerging as an important part of India’s clean-energy strategy. The government wants India to become a major producer and exporter of green hydrogen and its derivatives, while reducing dependence on fossil fuels.
Under the National Green Hydrogen Mission, India aims to produce 5 million tonnes of green hydrogen annually by 2030. In 2026, companies are moving from announcements toward pilot plants, production facilities, green-ammonia contracts and supporting infrastructure.
However, there are very few listed Indian companies that can be called pure-play green hydrogen stocks. Most listed companies provide exposure through renewable power, electrolysers, engineering, refining, gas infrastructure or green-ammonia projects.
Based on business exposure, project activity, scale and relevance to India’s hydrogen ecosystem, here are 5 green hydrogen-related stocks in India to watch in 2026.
Note: This is an educational watchlist, not a recommendation to buy or sell any stock.
Top 5 Green Hydrogen Stocks in India 2026

L&T is not a pure hydrogen company. Its diversified engineering business remains the major driver of its financial performance.
3. NTPC
NTPC Ltd. is India’s largest power-generation company and is expanding into green hydrogen and green-ammonia projects.
Its existing renewable-energy capabilities are important because green hydrogen production requires substantial amounts of renewable electricity.
NTPC Green Hydrogen-related initiatives include projects involving hydrogen production and applications in transport and industrial sectors. The company is also involved in green-ammonia initiatives.
In 2026, NTPC remained among the largest listed companies included in green-hydrogen stock screens.
India’s green-ammonia market is also developing. In March 2026, agreements involving NTPC Green and other suppliers covered 724,000 tonnes of green ammonia, according to Reuters.
Why watch NTPC?
- Large renewable-power base
- Green hydrogen projects
- Green-ammonia opportunity
- Strong government backing
- Established power infrastructure
- Potential long-term clean-energy growth
Key Risk
NTPC remains a diversified power company. Its conventional power-generation business continues to be much larger than its green hydrogen operations.
4. Adani Enterprises
Adani Enterprises (AEL) provides exposure to the green hydrogen opportunity through the wider Adani New Industries ecosystem.
The group has been developing an integrated renewable-energy and green-hydrogen supply chain, covering renewable power, electrolyser manufacturing, green hydrogen and green ammonia.
This integrated model is important because producing competitive green hydrogen requires access to low-cost renewable electricity and large-scale infrastructure.
Adani Enterprises is included among the major green-hydrogen stocks tracked by Indian market platforms. INDmoney’s July 2026 data showed it among the largest companies in the green-hydrogen theme by market capitalization.
The broader Adani group is also developing transmission infrastructure specifically to support planned green hydrogen and green-ammonia projects in Andhra Pradesh.
Why watch Adani Enterprises?
- Integrated renewable-energy ecosystem
- Green hydrogen and ammonia opportunity

The company’s hydrogen opportunity is part of a much broader business portfolio. Investors should also consider leverage, valuation, project execution and the financial performance of the overall group.
5. GAIL (India)
GAIL (India) is India’s largest natural-gas transmission and distribution company and is exploring opportunities in hydrogen and clean-energy infrastructure.
Its existing gas pipeline network could become relevant as India develops infrastructure for hydrogen blending, transportation and other applications.
GAIL has also been included among India’s major green-hydrogen-related stocks in 2026 market screens. Samco’s July 2026 list included GAIL among the leading hydrogen-theme companies.
India’s green-hydrogen ecosystem is also increasingly connected with green ammonia, industrial use and energy infrastructure. GAIL’s existing energy infrastructure provides a potential advantage as this market develops.
Why watch GAIL?
- Large gas transmission network
- Hydrogen infrastructure opportunity
- Government-owned energy company
- Existing industrial customer base
- Potential transition toward cleaner fuels
Key Risk
GAIL’s core business remains natural gas, so investors should not consider it a pure green hydrogen company.

Why Is Green Hydrogen Important in 2026?
Green hydrogen is produced using renewable electricity, generally through electrolysis of water. It can potentially replace fossil-fuel-based hydrogen in industries where direct electrification is difficult.
Important applications include:
- Fertiliser production
- Oil refining
- Steel manufacturing
- Shipping
- Heavy transport
- Green ammonia
- Industrial heating
- Long-duration energy applications
India currently consumes around 20 million tonnes of grey hydrogen annually, mainly in industrial applications. The government is attempting to shift part of this demand toward lower-carbon hydrogen.
India’s green-hydrogen production economics have also improved. Reuters reported in August 2026 that production costs had fallen to around ₹279 per kg, compared with roughly ₹5/kg equivalent in 2023.
Green Hydrogen vs Green Ammonia
Investors should understand the connection between these two terms.
Green hydrogen is hydrogen produced using renewable electricity.
Green ammonia is produced using green hydrogen and nitrogen. It can be easier to transport and is particularly relevant to the fertiliser industry.
India is increasingly developing both markets. In August 2026, SECI proposed an additional 1 million tonnes per year of locally produced green ammonia for fertiliser companies.
This could create additional opportunities for companies involved in renewable power, hydrogen production, ammonia production and related infrastructure.
How to Choose Green Hydrogen Stocks in India
Investors should not buy a stock simply because a company has announced a hydrogen project.
Check Actual Project Progress
Look for projects that have moved beyond announcements into construction, commissioning or commercial production.
Examine Investment Requirements
Green hydrogen projects require large amounts of capital. Investors should understand how companies plan to finance expansion.
Look at Renewable Power Access
Competitive green hydrogen requires low-cost renewable electricity. Companies with strong renewable-energy capabilities may have an advantage.
Study Electrolyser Capabilities
Electrolysers are a critical part of green hydrogen production. Companies developing or manufacturing them may benefit as the industry expands.
Check Offtake Agreements
Long-term agreements with industrial customers can provide better visibility for future hydrogen and green-ammonia demand.
Consider Valuation
A promising hydrogen business does not automatically make the stock attractive at every valuation.
Risks of Investing in Green Hydrogen Stocks
Green hydrogen is a promising but developing industry.
High production costs: Green hydrogen still needs to compete with conventional hydrogen and other fuels.
Large capital requirements: Production plants, renewable power and infrastructure require substantial investment.
Technology risk: Electrolyser technology continues to develop.
Demand uncertainty: Large-scale industrial demand is still developing.
Project execution: Delays can increase costs and postpone expected revenue.
Valuation risk: Hydrogen-themed stocks can rise on expectations before projects generate significant profits.
Are Green Hydrogen Stocks Good Investments in 2026?
Green hydrogen has a strong long-term policy and industrial-growth story in India. The National Green Hydrogen Mission, government incentives and emerging green-ammonia demand are helping create a new market.
However, most listed Indian companies involved in this theme are not pure green hydrogen companies.
Reliance provides exposure through its new-energy ecosystem, L&T through electrolysers and engineering, NTPC through renewable power and hydrogen projects, Adani Enterprises through an integrated clean-energy strategy, and GAIL through energy and potential hydrogen infrastructure.
Therefore, investors should evaluate actual project progress, capital expenditure, profitability, valuation and the company’s existing core business before investing.
Final Thoughts
Reliance Industries, Larsen & Toubro, NTPC, Adani Enterprises and GAIL are five green-hydrogen-related stocks investors can research in 2026.
India’s green hydrogen industry is still in its development phase, but government targets, renewable-energy expansion and industrial demand could create significant long-term opportunities.
At the same time, investors should remain cautious because future hydrogen potential is not the same as current hydrogen revenue. A company’s financial strength, project execution and valuation remain important when evaluating any green hydrogen stock.
