Maruti Suzuki launches 300 kW green hydrogen pilot at Manesar plant using surplus solar

Maruti Suzuki has installed a 300 kW green hydrogen plant at its Manesar facility. The pilot uses surplus solar power generated when the plant is not operating to run an electrolyser, producing hydrogen that is stored and blended with natural gas for use as process fuel in manufacturing. This approach tackles the challenge of decarbonizing fuel needs that cannot be met by direct electrification. The company aims to cut manufacturing carbon emissions from 615,000 tonnes to 266,000 tonnes by FY31. The pilot will help assess the feasibility of scaling green hydrogen across its facilities in Haryana and Gujarat. Maruti is also expanding solar, procuring renewable power through PPAs, and investing in biogas and battery storage, aligning with India's green hydrogen mission.

300 kW is small. The key is how much hydrogen per day and the electrolyser efficiency. Blending with natural gas for process heat, likely low percentage. Worth watching if they publish utilization rates.

The emissions target is solid, but the green hydrogen mission depends on the carbon intensity of the grid. If they use surplus solar, that's good. But scaling to other plants needs clear accounting for hydrogen production and use. Also check the cost per kg.

Blending hydrogen with natural gas for process fuel is interesting. But for industrial heat, the equipment may need retrofits. The pilot should test durability and burner modifications. Also compare with direct electrification of heat pumps.

Using excess solar for hydrogen instead of curtailing makes sense. But the electrolyser cost and maintenance might be high. The biogas and battery storage projects show a portfolio approach. Good to see automakers diversifying.
