MANESAR: Maruti Suzuki has commissioned a 300 kW green hydrogen electrolyser plant at its Manesar facility in Haryana, run as a pilot, and plans to widen the technology across its plants in Haryana and Gujarat based on what the pilot teaches it. The company announced the plant in a release dated 24 September.
Manesar lies in Gurugram district, so the plant is a local industrial development for Delhi NCR as well as a sustainability project.
How the plant works
The green hydrogen is blended with natural gas and used as process fuel in the factory's manufacturing operations. The plant relies on the solar energy generated at Manesar. Power produced on holidays, which would otherwise go unused, is used to make hydrogen. The hydrogen is stored and used later in production.
Hisashi Takeuchi, Managing Director and CEO, said the commissioning "is aligned with the Government of India's Green Hydrogen Mission." He added that India's competitive position "may not depend solely on cost and quality, but also on CO2 intensity."
The logic is about timing. Solar panels produce power on holidays when the line is idle, and that energy would normally go to waste. Converting it to hydrogen lets the factory carry it forward to working days.
The emissions target behind it
Maruti says it aims to cut the carbon footprint of its manufacturing operations from the present 615,000 tonnes to 266,000 tonnes in FY 2030-31. The release cites the company's Annual Integrated Report 2025-26 for the present figure.
The hydrogen plant is one piece of that effort. The release also mentions in-house solar plants, renewable power bought from government sources and third-party power purchase agreements for solar and wind energy.
Other projects named in the release
At Kharkhoda, the company is in the advanced stage of setting up a biogas plant of 10 tonnes per day, which it expects to commission within FY 2026-27. A 1 MWh battery energy storage system has already been commissioned at the same facility.
Maruti has begun using compressed biogas as process fuel. Its board has approved four compressed biogas projects and set aside Rs 5,610 million for them, which is Rs 561 crore. Separately, parent Suzuki Motor Corporation will set up 10 biogas plants across India with the National Dairy Development Board and dairy industry unions, and three are already working in Gujarat.
Maruti's other Haryana site named in the release is Kharkhoda, which is in Sonipat district, and its Gujarat plants are the other places where green hydrogen may follow.
What the release does not say
It gives no figure for how much hydrogen the pilot will produce, no cost, no share of plant fuel that hydrogen will replace and no date for the wider rollout. At 300 kW, the electrolyser is described as a pilot, and the company calls the scale-up conditional on what it learns.
That makes the announcement a statement of direction and not yet a measurable cut in emissions. The numbers that will matter are the quantity of hydrogen produced and the natural gas it displaces, and neither has been published.
