Maruti Suzuki commissions 300 kW green hydrogen plant at Manesar
Synopsis
Maruti Suzuki has moved beyond pledges — its 300 kW green hydrogen electrolyzer at Manesar is now live, using surplus solar power to produce fuel for the factory floor. With a target to slash manufacturing emissions by 57% before FY31, India's biggest carmaker is betting that carbon intensity will soon be as decisive a competitive factor as cost.
Key Takeaways
Maruti Suzuki commissioned a 300 kW green hydrogen electrolyzer plant at its Manesar facility in Haryana on 24 September 2026 .
The plant converts surplus solar energy into green hydrogen via electrolysis, which is then blended with natural gas as process fuel.
The company targets a reduction in manufacturing carbon emissions from 615,000 tonnes to 266,000 tonnes by FY31 .
MD and CEO Hisashi Takeuchi linked the project to a multi-pathway clean energy strategy also covering solar, biogas, and battery storage.
The pilot is aligned with the National Green Hydrogen Mission and is expected to inform scale-up across plants in Haryana and Gujarat .
Maruti Suzuki India Limited on Thursday, 24 September 2026 commissioned a 300 kW green hydrogen electrolyzer plant at its Manesar manufacturing facility in Haryana, marking the automaker's first operational green hydrogen unit and a concrete step toward reducing carbon emissions from its production operations.
How the Plant Works
The pilot facility will produce green hydrogen by channelling excess solar energy generated at the Manesar plant through an electrolysis process. The hydrogen will be stored and subsequently blended with natural gas to serve as process fuel in manufacturing activities.
Notably, one of the project's key design features is its ability to absorb surplus solar power during holidays and non-production days — periods when the plant's solar capacity would otherwise sit idle. This makes the electrolyzer a buffer for intermittent renewable generation, not merely a standalone hydrogen source.
What Maruti Suzuki's CEO Said
Managing Director and CEO Hisashi Takeuchi described the initiative as part of a broader multi-pathway approach applied to both products and manufacturing operations. Alongside the green hydrogen project, the company has invested in solar energy, biogas, and battery energy storage systems.
Takeuchi said India is increasingly emerging as a global manufacturing hub where competitiveness will be determined 'not only by cost and quality but also by carbon intensity.' He added that Maruti Suzuki is 'building capabilities today to support a low-carbon and energy-efficient manufacturing ecosystem in the future.'
Emission Reduction Targets
The commissioning forms part of Maruti Suzuki's published decarbonisation roadmap. The company is targeting a reduction in manufacturing-related carbon emissions from the current 615,000 tonnes to 266,000 tonnes by FY31 — a cut of roughly 57% — through the combined deployment of multiple clean energy technologies.
The Manesar pilot is also intended as a learning platform for scaling green hydrogen technology across the company's other facilities in Haryana and Gujarat.
Alignment with National Policy
The project is aligned with the Government of India's National Green Hydrogen Mission, which aims to make India a leading producer and exporter of green hydrogen. For Maruti Suzuki — India's largest passenger vehicle manufacturer by volume — adopting hydrogen at the factory level signals that industrial decarbonisation is beginning to move from policy commitment to shop-floor reality.
This comes amid growing pressure on large manufacturers to disclose and reduce Scope 1 and Scope 2 emissions, as global supply chains increasingly factor carbon intensity into sourcing decisions. The next phase will determine whether the pilot economics justify full-scale rollout.
Point of View
Not a transformation — but it is a more credible signal than most Indian manufacturers have sent. The design choice to absorb idle solar power during holidays is operationally clever and suggests genuine engineering intent rather than a PR install. The harder question is economics: green hydrogen remains expensive, and blending it with natural gas at this scale barely moves the emissions needle in absolute terms. The real test is whether the FY31 target of 266,000 tonnes is binding and independently verified, or another headline number that quietly recedes as production volumes grow.

Frequently Asked Questions
What is the green hydrogen plant Maruti Suzuki has commissioned at Manesar?
It is a 300 kW green hydrogen electrolyzer that uses surplus solar energy generated at the Manesar facility to produce hydrogen through electrolysis. The hydrogen is blended with natural gas and used as process fuel in manufacturing operations.
How does the Manesar electrolyzer use solar power?
Excess solar energy that would otherwise go unused — particularly on holidays when the plant is not in full production — is directed to the electrolyzer to generate green hydrogen. The hydrogen is then stored and released for use when manufacturing resumes.
What is Maruti Suzuki's carbon emission reduction target?
Maruti Suzuki aims to reduce manufacturing-related carbon emissions from the current 615,000 tonnes to 266,000 tonnes by FY31, a reduction of roughly 57%, through a combination of green hydrogen, solar energy, biogas, and battery storage systems.
How does this project relate to India's National Green Hydrogen Mission?
The plant is explicitly aligned with the Government of India's National Green Hydrogen Mission, which aims to position India as a global green hydrogen producer. For Maruti Suzuki, it represents an industry-level adoption of a policy that has so far been dominated by energy sector announcements.
Will the technology be expanded to other Maruti Suzuki plants?
Yes. Maruti Suzuki has described the Manesar unit as a learning platform for wider deployment of green hydrogen technology across its manufacturing facilities in Haryana and Gujarat, subject to the lessons and economics established by this pilot.
