India's National Green Hydrogen Mission is set to revolutionize the country's energy sector with a projected investment of ₹10.6 lakh crore ($129 billion) by 2030. The initiative aims to produce 5 million tonnes of green hydrogen annually and add 135 GW of renewable energy capacity, primarily from wind and solar sources. This ambitious mission is part of India's strategy to decarbonize its energy sector, reduce dependence on fossil fuels, and achieve net-zero emissions by 2070. Key states like Gujarat and Tamil Nadu will play a critical role in this transition, with significant contributions from other states as well. The production of green hydrogen is expected to significantly impact India's power demand, pushing total demand to 409 GW by 2030. The mission also aims to position India as a leading exporter of green hydrogen to global markets. As renewable energy's share increases, India's power grid will require more flexibility to accommodate fluctuating supply, with electrolysers playing a crucial role. The report projects a decrease in the average cost of power generation, making green hydrogen more competitive and contributing to the affordability of clean energy in India. Overall, India's green hydrogen mission signifies a bold step towards a cleaner and more sustainable future, with the potential to establish the country as a major player in the global energy market.
