Integration of Green Hydrogen in Rural Regions of India for Reliable and Secure Supply Through Decentralized Renewable Solutions

India has made significant progress in electrification, but rural areas still face issues with power reliability and sustainability due to frequent outages and voltage fluctuations in the existing centralized grid system. To address these issues, decentralizing power generation with green hydrogen as storage and backup is proposed. This paper examines the financial feasibility of integrating green hydrogen and renewable energy in rural India. Using HOMER Pro Software, simulations showed that integrating these technologies significantly reduces costs and emissions. Net Present Cost (NPC) and Levelized Cost of Energy (LCOE) dropped by 60.4%, operational and maintenance costs decreased by 74.2%, and emissions were reduced by 65-85%. Financial metrics suggest a 2—3-year breakeven point due to declining costs for electrolyzers and storage facilities by 2030. The study concludes that decentralizing power generation with green hydrogen and renewable energy can reduce the carbon footprint and promote sustainable development.
