India is set to invest INR 10.6 lakh crore (USD 129 billion) by 2030 to drive its green hydrogen production targets. A report by the Council on Energy, Environment and Water outlines the necessity of this massive investment to deploy 135 GW of renewable energy capacity and 74 GW of electrolyser capacity. Meeting the National Green Hydrogen Mission's goal of 5 million tonnes annually by 2030 will require a substantial expansion in grid-connected renewable energy, impacting the power system significantly. The report highlights the challenges posed by the concentration of renewable energy capacity in a few states and the need for additional infrastructure, especially in transmission. The ambitious targets will drive up peak electricity requirements, necessitating the integration of more renewable energy sources like solar and wind. Gujarat and Tamil Nadu are anticipated to play crucial roles in this renewable energy expansion. Moreover, the report stresses the importance of utilizing the inter-state transmission system to manage costs effectively and ensure the feasibility of green hydrogen production. Overall, strategic investments and infrastructure development are paramount to supporting India's transition to a sustainable, low-carbon energy system.
