The Indian Army's off-grid location in Chushul, Ladakh, will soon be powered by a solar hydrogen-based microgrid, eliminating the reliance on diesel gensets. This innovative system, developed by NTPC, aims to ensure a continuous energy supply even in extreme winter conditions where temperatures can drop to -30°C at an altitude of 4,400 meters. The system, operated independently using hydrogen as an energy storage medium, will provide 200kW of power year-round. It replaces diesel gensets, promoting sustainability and operational efficiency for the Indian Army. The project aligns with the 'National Green Hydrogen Mission' and showcases NTPC's commitment to renewable energy targets and carbon neutrality. By leveraging Ladakh's solar irradiance and low temperatures, the system combines solar power with hydrogen energy storage to offer a reliable and eco-friendly solution. Additionally, NTPC is conducting trials for hydrogen buses in Leh and setting up hydrogen fuelling stations and solar plants, furthering its green energy initiatives. This project not only enhances the military infrastructure's resilience but also paves the way for decarbonisation and self-sufficiency in challenging terrains.
