In a recent development, an innovative hydrogen fuel cell-based backup power solution for telecom towers has been introduced in India, particularly targeting remote areas with limited grid access. Traditionally, diesel generators were used as backup power sources, but due to their cost and carbon emissions, there was a need for a more sustainable solution. PEM (Proton Exchange Membrane) fuel cells emerged as an efficient and clean energy solution for powering these towers during grid outages. These fuel cells operate on hydrogen fuel, providing reliable electricity with quick start-up times and low maintenance requirements. The initiative, driven by the Department of Science and Technology and supported by the Department of Telecommunications and TRAI, aims to promote greener energy solutions in the telecom sector. The Centre for Fuel Cell Technology (CFCT) at ARCI developed the innovative fuel cell-based solution, focusing on a plug-and-play model for easy deployment and transport, making it adaptable for widespread use. The demonstration of a mobile PEMFC-based backup power solution in Pune showcased the potential of shared power generation units among multiple towers, enhancing backup power availability. This project, part of the Advanced Hydrogen and Fuel Cell Call – 2021, signifies a shift towards cleaner and more reliable telecom operations in India, aligning with the country's sustainability goals. With a growing focus on sustainability and clean energy, fuel cell technology presents a promising solution for the telecom sector, offering uninterrupted service while significantly reducing carbon footprints. The successful deployment of PEM Fuel Cells for telecom towers is a significant milestone in promoting clean energy adoption and enhancing the reliability of telecom operations.
