Power giant NTPC and the Indian Army have entered into a landmark agreement to supply 200 kilowatts of round-the-clock renewable energy from a solar-hydrogen-based microgrid in Ladakh. This initiative, set to replace diesel generators, is part of the military's shift towards sustainable energy solutions, with a focus on decarbonization and modernization of defence infrastructure. The military's emphasis on renewable energy is evident in its experimentation with hydrogen fuel cell technology for transportation and the gradual integration of electric vehicles into its fleet. The Indian Army's commitment to sustainability extends to providing renewable heating and power solutions for troops stationed in extreme climates, exemplified by collaborations with organizations like DRDO and DIHAR in Leh. Moreover, the military's efforts to incorporate large-scale solar power projects and passive solar shelters demonstrate a holistic approach to enhancing operational energy efficiency and reducing environmental impact. By embracing hydrogen and renewable energy initiatives, the Indian Army is positioning itself as a leader in sustainability-driven military transformation, aligning with India's broader goals of achieving net-zero emissions by 2070.
