Hydrogen, recognized as a potential energy carrier since 1766, is now a focal point in discussions about decarbonizing challenging sectors like heavy industry and long-haul transport. While most hydrogen currently produced is 'grey' hydrogen from fossil fuels, there is a global push towards green hydrogen made through water electrolysis using renewable energy sources. India has launched its National Green Hydrogen Mission to boost green hydrogen production and create cost parity with grey hydrogen. The focus is on creating a demand pipeline to attract investments, particularly in new sectors like steel, chemicals, and transport. India sees export potential in East Asia, specifically in Japan and South Korea, due to their constraints in expanding renewable energy and growing demand for green hydrogen. Both countries have shown support for green hydrogen initiatives, offering subsidies and establishing supply networks. The collaboration between Japan and Korea in hydrogen supply creates an opportunity for India to become a competitive green hydrogen supplier. The geographical proximity and shared emphasis on green hydrogen make East Asian markets an attractive destination for Indian exports. India's exclusive focus on green hydrogen production distinguishes it in the global market, presenting a strategic advantage in international partnerships for a sustainable energy future.
