India's growing digital infrastructure and sustainability focus have led to the development of a cutting-edge hydrogen fuel cell-based backup power solution for telecom towers. With over a million towers in the country, many located in remote areas, traditional diesel generators have been the go-to backup power source despite their drawbacks. Proton Exchange Membrane Fuel Cells (PEMFC) have emerged as a promising alternative, offering high efficiency, low operational costs, and near-zero emissions. These fuel cells generate electricity by combining hydrogen and oxygen, making them ideal for telecom applications during grid outages. The government's push towards renewable energy, with directives mandating a shift to hybrid sources for telecom towers, aligns with the adoption of PEM fuel cells. An innovative plug-and-play model developed by the Centre for Fuel Cell Technology enables easy deployment of PEMFC-based backup power solutions. Successful demonstrations in collaboration with industry leaders like Resicorre Technologies have showcased the viability of hydrogen fuel cells in enhancing network resilience and reducing carbon footprint in the telecom sector. This advancement highlights the potential of fuel cell technology to revolutionize power solutions for critical infrastructure and contribute to India's broader renewable energy and sustainability objectives.
