India's National Green Hydrogen Mission, launched in January 2022, sets ambitious goals for the country to become a leading producer and exporter of green hydrogen. The mission, overseen by the Ministry of New and Renewable Energy (MNRE), targets an annual green hydrogen output of 5mn tonnes by 2030. To support this initiative, the government introduced the SIGHT Programme – Component II aimed at incentivizing green ammonia production, particularly for the fertiliser sector. The mission not only focuses on boosting green hydrogen production but also includes plans to add 125 GW of renewable energy capacity by 2030. This strategic move aims to shift various sectors in India, including refining, steel, transport, and remote power access, from fossil-based inputs to cleaner alternatives. Despite the potential for green hydrogen and green ammonia to replace fossil fuels, challenges exist. Crisil Ratings highlights a significant cost gap between green and grey hydrogen production, indicating the need for substantial cost reductions in renewable power and electrolyser components to enhance competitiveness. While the government provides short-term incentives through the SIGHT scheme, ongoing regulatory support, financial incentives, and access to long-term financing will be crucial to sustain investments in green hydrogen production. With the high capital investment required for green hydrogen projects, estimated at $16–18bn per million tonnes per annum of capacity, ongoing government support will play a vital role in achieving the mission's objectives. Moreover, the cost gap challenges also impact long-term offtake commitments from buyers. The uncertainty around future cost reductions creates hesitation among buyers to commit to current prices. However, with industry participants expecting cost reductions and efficiency improvements in electrolyser technology by 2030, advances in technology and regulatory support will be essential for the growth of the green hydrogen industry in India.
