Key Highlights:

  • The Indian Army entered into an MoU with IOCL to conduct demonstration trials of Hydrogen Fuel Cell Bus technology, marking a significant step towards fostering innovation and sustainable transport solutions.
  • The bus, equipped with seating for 37 passengers, showcased a promising mileage of 250-300 km on a full 30 kg onboard tank of Hydrogen fuel.
  • Hydrogen Fuel Cell technology, employed in the bus, converts Hydrogen gas into electricity through an electrochemical process, producing only water vapour as a by-product, thus ensuring zero emissions.


Green Hydrogen Fuel Cells:

  • These are exceptional sources of clean, dependable, noiseless, and efficient electric power that harnesses Green Hydrogen as a fuel for an electrochemical process that generates electricity, producing only water and heat as by-products.
    •  Green Hydrogen: Green hydrogen is produced through electrolysis, utilizing renewable energy sources like wind and solar power. This process splits water (H2O) into its elements, hydrogen (H2) and oxygen (O2), without emitting any greenhouse gases.
    • Fuel Cell: It is an electrochemical device that converts chemical energy (hydrogen) into electrical energy. It comprises two electrodes (anode and cathode) separated by an electrolyte.




  • This initiative underscores the Indian Army’s commitment to adopting clean and efficient energy alternatives.
  • By using Hydrogen Fuel Cell technology, the Army aims to reduce environmental impact while exploring innovative solutions for future transport needs.
  • Additionally, the Army’s collaboration with IOCL sets a precedent for public-private partnerships in advancing sustainable development goals in India’s defense sector.
  • This initiative aligns with broader efforts to integrate green technologies into critical operations, exemplified by ongoing projects like the deployment of green hydrogen-based microgrid power plants in challenging terrains along the Northern Borders.
