India is planning a massive expansion of green hydrogen production to curb its reliance on energy imports and free the economy from fossil fuels. Green hydrogen is made by splitting water using electricity from renewable energy sources. New Delhi aims to have an annual capacity of 25 million tonnes by 2047, the people said. India's goal of net-zero emissions by 2070 is backed by business tycoons and state-run energy giants. Green hydrogen is made by splitting hydrogen and oxygen in water with the help of electrolyzers, which are powered by renewable electricity. It has the potential to be an alternative to coal for steel mills and to transport petroleum products over long distances.
