Maruti Suzuki India has commissioned a 300kW green hydrogen electrolyser plant at its manufacturing facility in Manesar, Haryana. The company said the project is currently being operated as a pilot to assess the potential use of green hydrogen in manufacturing operations. The hydrogen produced at the plant is blended with natural gas and used as process fuel.
The project uses surplus solar power generated at the Manesar facility. During holidays, when electricity demand at the plant is lower, excess solar energy is used to produce hydrogen through the electrolyser. The hydrogen is then stored and used in manufacturing operations as required.
According to the project model, the hydrogen produced is compressed and stored before being blended with natural gas. The resulting fuel mixture is then supplied for use in manufacturing processes. Maruti Suzuki has not disclosed the hydrogen production capacity of the pilot plant in tonnes per day, apart from specifying the 300kW electrolyser capacity.
Maruti Suzuki Managing Director and CEO Hisashi Takeuchi said the 300kW plant is aligned with the government’s Green Hydrogen Mission. He said the company is adopting a multi-technology approach to reduce emissions from its manufacturing operations, including solar power, biogas, battery energy storage and green hydrogen.
The company aims to reduce the carbon footprint of its manufacturing operations from 615,000 tonnes to 266,000 tonnes by FY2030-31. Maruti Suzuki said the targeted reduction will be supported by multiple renewable and clean-energy technologies rather than green hydrogen alone.
Based on the learnings from the green hydrogen pilot, the company will assess the potential for wider deployment across its manufacturing facilities in Haryana and Gujarat. Separately, Maruti Suzuki is in the advanced stages of setting up a 10 tonnes per day biogas plant at its Kharkhoda facility, which is scheduled for commissioning during FY2026-27. The company has also commissioned a 1MWh battery energy storage system at the site.
Maruti Suzuki has also started using Compressed Biogas (CBG) as a process fuel. Its board has approved four CBG projects with a total budget allocation of ₹561 crore. Separately, Suzuki Motor Corporation, in partnership with the National Dairy Development Board and dairy industry unions, plans to establish 10 biogas plants in India, of which three are already operational in Gujarat.
