NTPC has joined forces with the Indian Army to set up a Solar Hydrogen-based Microgrid in Chushul, Ladakh. This initiative aims to provide a reliable power supply using Green Hydrogen in off-grid Army locations. Today, Honorable Defence Minister Shri Rajnath Singh laid the foundation stone for this unique project via video conference, attended by the Chief of Defence Staff, the CMD of NTPC, and other senior officials from the Ministry of Defence, Indian Army, and NTPC.
The innovative Solar Hydrogen-based microgrid system, designed by NTPC, will operate independently and utilize hydrogen as an energy storage medium to deliver 200 kW of power continuously throughout the year. This system is set to replace existing diesel generators at off-grid Army locations, ensuring a sustainable power supply even in extreme winter conditions, where temperatures can plummet to -30°C at an elevation of 4,400 meters. NTPC will oversee the maintenance of the project for 25 years, providing vital support to Indian soldiers stationed in these strategically important and challenging terrains.
The Solar-Hydrogen microgrid will take the place of current diesel generators in use at off-grid Army sites. These systems offer numerous benefits, including the integration of renewable energy sources, stable power delivery under harsh conditions, reduced carbon emissions, and the promotion of a cleaner, more sustainable energy ecosystem. They are also highly scalable and suitable for various applications, combining reliable battery storage with the extended energy storage capacity of hydrogen for consistent power supply.
With Ladakh’s high solar irradiance and low temperatures, this project will enable the production and use of green energy, decreasing dependence on fuel logistics and improving self-sufficiency in remote areas that face connectivity challenges. Once operational, it will mark a significant step toward decarbonizing the defense sector in the Himalayan region.
Additionally, NTPC has recently initiated a trial run of a hydrogen bus in Leh as part of its renewable energy targets and efforts toward carbon neutrality in Ladakh. The company is also establishing a hydrogen fueling station and solar plant, alongside five fuel cell buses for operation on intracity routes in Leh.
NTPC aims to achieve 60 GW of renewable energy capacity by 2032, positioning itself as a leader in green hydrogen technology and energy storage. The company is pursuing various decarbonization initiatives, including hydrogen blending, carbon capture, electric buses, and the development of smart NTPC townships.
