Green hydrogen is gaining importance in India as a key technology to decarbonise challenging sectors such as steel, fertilisers, and shipping fuels. Despite its potential, green hydrogen faces obstacles like high costs and limited availability. To overcome these challenges and position India as a global green hydrogen leader, accelerated investments in project development and infrastructure are crucial. Hydrogen hubs, emerging as clusters of producers, users, and infrastructure, can drive economies of scale and enhance cooperation among stakeholders. They play a vital role in scaling up domestic production, utilizing export markets, and overcoming early market barriers. India's National Green Hydrogen Mission aims to transform the country into a green hydrogen hub, with a focus on careful location selection based on renewable energy availability and infrastructure. Case studies like the Kochi Green Hydrogen Hub in Kerala highlight ambitious targets for green hydrogen consumption, industry adoption, and export partnerships. With significant investments and job creation potential, these hubs aim to revolutionize India's energy landscape by reducing CO2 emissions and driving the transition towards a sustainable future.
