India's National Green Hydrogen Mission is paving the way for a green hydrogen revolution in the country, with a focus on transforming key sectors like steel, railways, and oil and gas. The mission targets the production of 5 million metric tonnes of green hydrogen annually by 2030, with plans to add significant renewable energy and electrolyser capacity. This initiative aims to reduce carbon emissions, save on imports, and attract substantial investments. In the steel sector, companies like JSPL and JSW Steel are deploying green hydrogen in their operations to reduce emissions and transition to green steel production. The integration of green hydrogen in steelmaking processes can lead to a significant reduction in carbon emissions and improve overall emission intensity. The Ministry of New and Renewable Energy has allocated budgetary support for pilot projects in the steel sector to enable the adoption of green hydrogen technologies. In the railway sector, Indian Railways is working towards achieving net-zero emissions by 2030 and is focusing on hydrogen-powered trains. Policy initiatives and schemes like the 'Hydrogen for Heritage' scheme are facilitating the uptake of green hydrogen in the railway sector. Overall, the article highlights the progress, developments, and policy support for green hydrogen adoption in India's industrial sectors, showcasing a positive outlook towards sustainable energy transition.
