India has introduced a hydrogen fuel cell-based backup power system for telecom towers, aiming to revolutionize the industry by promoting clean energy and ensuring continuous connectivity. With over a million telecom towers across India, especially in rural areas with unreliable grid connections, maintaining 24/7 operations has been challenging. Instead of conventional diesel generators, the innovative Proton Exchange Membrane Fuel Cells (PEMFC) are being utilized to generate electricity with water vapor as the only by-product, offering an efficient and environmentally friendly option. These fuel cells, powered by hydrogen, provide rapid start-up, low temperature operation, and require minimal maintenance, making them ideal for telecom towers during grid failures. The Department of Telecommunications and TRAI have been advocating for greener energy solutions, with a directive mandating a transition to hybrid renewable energy sources. This initiative, led by the Centre for Fuel Cell Technology (CFCT) of ARCI, features a plug-and-play design, enhancing transportability and reducing security risks for mass deployment. A recent demonstration in collaboration with Resicorre Technologies showcased the flexibility of the system, where the power generation unit can be shared among multiple towers, simplifying deployment in areas where diesel generators are impractical. This effort, funded by the Department of Science and Technology, underscores India's commitment to sustainable energy and technological advancements. The successful integration of PEM fuel cells into telecom infrastructure not only improves operational efficiency but also contributes to reducing carbon footprints, paving the way for a cleaner and more resilient telecom sector amidst the country's digital expansion.
