Automobile manufacturer Maruti Suzuki India has commissioned a 300 kW green hydrogen electrolyzer plant at its Manesar manufacturing facility in Haryana. The pilot plant will produce green hydrogen for use as process fuel in the company’s manufacturing operations.

The green hydrogen will be blended with natural gas before being used for manufacturing operations.

Maruti Suzuki said the project will help the company increase the utilization of solar power generated at the facility. Solar power generated during holidays that would otherwise remain unused will be used to produce green hydrogen. The hydrogen will be stored for subsequent use in manufacturing operations.

Based on learnings from the pilot project, the company plans to expand the use of green hydrogen technology across its manufacturing facilities in Haryana and Gujarat.

The green hydrogen project, along with solar power expansion, biogas, and battery energy storage, forms part of the company’s efforts to transition to cleaner energy sources.

Maruti Suzuki said it is has been adopting diverse renewable energy solutions across its manufacturing operations, including in-house solar projects, renewable energy procured from government sources, and solar and wind power supplied through power purchase agreements with third-party providers.

The company is in the advanced stages of setting up a 10 tons per day biogas plant at its Kharkhoda facility, in Haryana. The company expects to commission the plant during the financial year 2027. In June 2025, Maruti Suzuki commissioned a 20 MW solar power project at this facility and added another 10 MW of capacity at its Manesar plant.

It recently commissioned a 1 MWh battery energy storage system at the Kharkhoda facility.

Maruti Suzuki stated that it has also started integrating compressed biogas as a process fuel. Its board recently approved four compressed biogas projects and allocated ₹5.61 billion (~$58.5 million) for them.

Green hydrogen is expected to see strong demand from hard-to-abate industries where electrification is difficult, including refineries, chemical plants, and fertilizer manufacturing.
