The Indian government is considering a new hydrogen fuel cell-based backup power solution for telecom towers as an innovative and eco-friendly alternative to traditional diesel generators. Proton exchange membrane (PEM) fuel cells, which utilize hydrogen to generate electricity, have emerged as a promising technology due to their efficiency and low environmental impact. These fuel cells operate at lower temperatures, start up quickly, and require less maintenance compared to diesel generators. With over a million telecom towers in India, many located in remote regions, the switch to hydrogen fuel cells could significantly reduce costs and carbon emissions. TRAI's directive to transition a portion of telecom towers to renewable energy aligns well with this initiative. While a specific timeline for implementation is not yet defined, integrating PEM fuel cells with telecom towers has the potential to transform the power supply landscape in India, offering a cleaner and more sustainable energy solution for both urban and rural areas.
