In Tamil Nadu, a significant push towards hydrogen innovation is underway with collaboration between IIT Madras, Hyundai Motors, and the state government. The Hyundai HTWO Innovation Centre, located at IIT-M's Thaiyur campus, is at the forefront of developing a comprehensive hydrogen supply chain. This initiative includes localising electrolyzers for hydrogen production, creating microgrids, and establishing refuelling stations for hydrogen mobility. The centre aims to engage small and medium enterprises (MSMEs) in various stages of the production lifecycle, leveraging local manufacturing capabilities. IIT-M possesses expertise in various hydrogen technologies like solar water splitting, electrolyzers, microgrids, gas turbines, and fuel cells, which will be refined for commercial-grade applications. With a focus on precision manufacturing and coating capabilities of local industries in Chennai and surrounding regions, the centre aims to make hydrogen technology more efficient and economically viable for widespread adoption. The active involvement of MSMEs is considered crucial for achieving India's goals in localising green hydrogen infrastructure. Hyundai Motors' substantial funding and expertise in hydrogen technology underscore its commitment to advancing the hydrogen ecosystem. The collaboration between industry, academia, and government bodies signifies a holistic approach towards building a sustainable hydrogen economy in the region.
