Maruti Suzuki Green Hydrogen Plant Starts Manesar Pilot

Maruti Suzuki Green Hydrogen Plant at the company’s Manesar manufacturing facility in Haryana is a 300kW electrolyser pilot designed to produce hydrogen for manufacturing operations. The hydrogen generated at the site is blended with natural gas and used as process fuel, making the project part of the automaker’s broader effort to reduce emissions from production. The pilot uses renewable electricity already generated at Manesar, with surplus solar power available during holidays redirected to hydrogen production. The resulting hydrogen is stored for later manufacturing use, allowing Maruti Suzuki India to test how excess renewable generation can support industrial fuel requirements.

Manesar Green Hydrogen Pilot

The project is built around solar electricity that would otherwise have limited immediate use when manufacturing demand is lower during holidays. That surplus power is directed to the electrolyser, which produces hydrogen that is subsequently stored and supplied to manufacturing operations. The project diagram described by Maruti Suzuki shows the hydrogen being compressed, stored and blended with natural gas before reaching the process-fuel system. This configuration allows the company to evaluate green hydrogen within an existing industrial fuel arrangement while using renewable electricity produced at the same manufacturing location rather than relying solely on additional external power sources.

Electrolyser Capacity and Planned Expansion

Maruti Suzuki said the Manesar installation is currently a pilot project, and the company has not disclosed hydrogen production in tonnes per day in its release. The stated specification is a 300kW electrolyser capacity. This distinction is important because electrolyser power capacity alone does not establish a daily hydrogen output figure without additional operating assumptions and technical details. The company plans to use the experience and operational learnings from the pilot to assess broader green hydrogen deployment across its manufacturing facilities in Haryana and Gujarat. The project therefore serves as a test case for future scaling rather than a disclosed full-scale production system.

Broader Manufacturing Decarbonization Program

The initiative forms part of Maruti Suzuki’s wider manufacturing decarbonization program, which combines several renewable-energy technologies rather than relying on green hydrogen alone. The company said its approach includes solar power, biogas and battery energy storage, while renewable electricity is also sourced through government sources and power purchase agreements covering solar and wind power. Managing director and CEO Hisashi Takeuchi said the 300kW project aligns with the government’s Green Hydrogen Mission and supports a multi-technology strategy for reducing manufacturing emissions. The company’s stated objective is to reduce the carbon footprint of its manufacturing operations from 615,000 tonnes to 266,000 tonnes in FY2030-31.

Biogas and Battery Energy Storage Initiatives

Maruti Suzuki is also expanding its use of biogas and energy-storage technologies at other manufacturing locations. At Kharkhoda, the company is in the advanced stages of establishing a 10 tonnes per day biogas plant, with commissioning scheduled within FY2026-27. The site has also received a 1MWh battery energy storage system. These projects complement the hydrogen pilot by addressing different parts of the manufacturing energy system. The company has started integrating compressed biogas as a process fuel, while its board has approved four CBG projects with a combined budget allocation of ₹561 crore, adding another pathway for reducing reliance on conventional fossil-based process fuels.

Renewable Energy Expansion Across India

The renewable-energy program extends beyond Maruti Suzuki’s own manufacturing projects. Suzuki Motor Corporation, together with the National Dairy Development Board and dairy industry unions, plans to establish 10 biogas plants in India, with three already operational in Gujarat. In the manufacturing context, these efforts show how different renewable and low-carbon energy sources can be combined according to site requirements and available resources. The Manesar hydrogen pilot specifically tests the use of surplus solar electricity for hydrogen production, while biogas and battery storage address other energy needs. Maruti Suzuki has indicated that the lessons from these projects will help shape its broader manufacturing energy strategy.

Using Surplus Solar Power for Hydrogen

The Manesar project also illustrates a practical challenge in expanding green hydrogen for industrial use: matching renewable electricity availability with fuel demand. By using surplus solar generation during holidays and storing the resulting hydrogen for later consumption, the pilot is designed around a specific operating pattern at the manufacturing site. Its results can help the company assess the technical and operational requirements of integrating hydrogen into process-fuel systems. Any wider rollout across Haryana and Gujarat will depend on the experience gained from the pilot, the suitability of individual facilities and the performance of the company’s broader mix of renewable-energy technologies.

Manufacturing Emissions Reduction Strategy

The project’s significance is therefore tied to how Maruti Suzuki combines multiple decarbonization technologies across its manufacturing network. Green hydrogen can provide a way to convert surplus renewable electricity into a storable fuel for industrial use, while solar, biogas, battery storage and renewable power purchases address other energy requirements. The company’s stated FY2030-31 carbon-footprint target provides the broader context for these initiatives, but Maruti Suzuki has not attributed that planned reduction to green hydrogen alone. The Manesar pilot is intended to generate operational evidence that can inform decisions about whether and how hydrogen should be expanded at additional facilities.

Industry Impact & Outlook

Maruti Suzuki’s Manesar pilot provides a practical test of whether surplus renewable electricity can be converted into storable hydrogen and integrated with existing manufacturing fuel systems. For the automotive industry, the approach could offer another pathway for reducing process-related emissions at facilities where renewable power availability and industrial fuel demand do not always align. The immediate focus remains on gathering operational experience, while any wider deployment across Haryana and Gujarat will depend on the pilot’s results and the suitability of individual plants. The company’s parallel investments in solar, biogas and battery storage indicate that future manufacturing decarbonization will involve multiple technologies working together.

Frequently Asked Questions

What is Maruti Suzuki’s Manesar green hydrogen project?
Maruti Suzuki’s Manesar pilot uses surplus solar electricity to produce hydrogen, which is stored and blended with natural gas for manufacturing process fuel. The project has a 300kW electrolyser and is currently intended to provide operational experience rather than disclosed full-scale hydrogen production. The company said the lessons will help evaluate wider deployment across its Haryana and Gujarat manufacturing facilities. Maruti Suzuki has not disclosed a tonnes-per-day hydrogen output figure for the pilot, so the 300kW electrolyser capacity should not be interpreted as a daily production rate.
