Maruti Suzuki India has commissioned a 300 kW green hydrogen electrolyser plant at its Manesar manufacturing facility in Haryana. The pilot project is based on the production of hydrogen from surplus solar power by adding it to natural gas and using it as a process fuel for the production of the final product. The move brings hydrogen technology to the carmaker’s expanding list of renewable energy solutions, according to Maruti Suzuki India’s regulatory filing dated September 24, 2026.
The plant aims to tackle one of the main issues with renewable energy: surplus solar power generated when the factory does not need it. This electricity may be channelled to the electrolyser during the holidays to create green hydrogen. The hydrogen is then stored and used when required, effectively turning excess renewable electricity into a storable fuel.
The technology uses solar power, a water treatment system and an electrolyser to produce hydrogen. The hydrogen is stored in a buffer vessel from which it is compressed and stored for use later.
Hydrogen can be provided after pressure reduction and mixed with natural gas for immediate manufacturing needs. In addition to using renewable energy directly in its manufacturing, this provides another option for Maruti Suzuki to incorporate renewable energy into its operations.
According to , the pilot will also help the company understand the practical use of green hydrogen at an automotive manufacturing site. As per the outcomes, it is looking forward to rolling out the technology in its manufacturing base across Haryana and Gujarat.
The hydrogen project is a part of Maruti Suzuki’s total emissions reduction initiative at its factories. The company already has a significant amount of in-house solar generation, as well as renewable energy through a range of contracts, including solar and wind power purchase agreements.
is also working on a 10-tonne-per-day biogas plant at Kharkhoda which will be commissioned in FY 26-27. It has installed a 1 MWh BESS system in the same location. The company’s board has also approved four compressed biogas projects, with an allocated budget of ₹561 crore, according to the company’s statement.
According to Maruti Suzuki, their effort on clean energy helps them to be more efficient in the use of resources and lower the carbon intensity of production. The company has currently estimated its manufacturing carbon footprint is approximately 615,000 tonnes and is looking to reduce this to 266,000 tonnes by FY 2030-31.
Managing Director & CEO of Maruti Suzuki India, Hisahi Takeuchi, outlined the company’s efforts to move towards eco-friendly manufacturing practices by investing in various renewable energy technologies, including solar power, biogas, battery storage, and green hydrogen.
