The Green Hydrogen produced is blended with natural gas to be utilized as process fuel in the Company’s manufacturing operations. The Green Hydrogen plant helps maximise the utilisation of solar energy generated at the Company's Manesar facility. Solar energy produced during holidays, which would otherwise remain unutilised, is used to generate Green Hydrogen. The hydrogen is stored and subsequently used in manufacturing operations. Based on the learnings from this pilot project, the Company plans to scale up the adoption of green hydrogen technology across its manufacturing facilities in Haryana and Gujarat. Drawing inspiration from the parent company Suzuki Motor Corporation’s (“SMC”) core philosophy of Sho-Sho-Kei-Tan-Bi, which translates to smaller, fewer, lighter, shorter and more beautiful, Maruti Suzuki continues to improve resource efficiency and optimise energy requirements. Speaking on the pilot initiative, Mr. Hisashi Takeuchi, Managing Director & CEO, Maruti Suzuki India Limited, said, “Just like we have adopted a multi-pathway approach for products, we have also embarked on a journey of multiple renewable energy solutions for manufacturing operations. The commissioning of our 300 kW Green Hydrogen plant is aligned with the Government of India’s Green Hydrogen Mission. This, along with expansion of solar, biogas and installation of battery energy storage system reflects our commitment to transition to cleaner and sustainable energy solutions.” He added, “India is emerging as a manufacturing powerhouse, and its competitive position may not depend solely on cost and quality, but also on CO intensity. With such initiatives, we are building capability today so that we can support a low-carbon and more energy-efficient manufacturing ecosystem tomorrow. Through multiple clean technologies, we aspire to reduce our carbon footprint in manufacturing operations from the present 615,000 tonnes to 266,000 tonnes in FY 2030-31i.” Maruti Suzuki’s efforts to reduce carbon emissions from its manufacturing processes Maruti Suzuki continues to advance its efforts to reduce carbon emissions across its manufacturing operations by adopting diverse green energy solutions. These include in-house solar power plants, renewable energy procurement from government sources, and power purchase agreements with third-party providers for solar and wind-based energy. In addition, Maruti Suzuki is in the advanced stage of setting up a 10 Tonnes Per Day (TPD) biogas plant at its Kharkhoda facility, which will be commissioned within FY 2026-27. Recently, the Company also commissioned a 1 MWh Battery Energy Storage System at its Kharkhoda facility. The Company has begun integrating compressed biogas (CBG) as process fuel. Recently, the Company’s board approved 4 CBG projects and earmarked a budget of INR 5,610 million towards the same. Separately, SMC in partnership with organizations such as the National Dairy Development Board (NDDB) and dairy industry unions will set up 10 biogas plants across India, three of which are already operational in Gujarat. The commissioning of the pilot Green Hydrogen plant further strengthens Maruti Suzuki’s portfolio of clean energy sources for process fuels, marking another milestone in its journey toward sustainable manufacturing.
