The Korean Army is spearheading a monumental shift towards hydrogen energy by planning to replace its current fleet of military vehicles, which are powered by internal combustion engines, with hydrogen-powered alternatives. This initiative, carried out in partnership with Korea's leading mobility technology companies like Hyundai Motor, Kia Corp., Hyundai Rotem, and Doosan Mobility, aims to enhance energy efficiency and reduce emissions in military operations. The Seventh Mobile Corps of the Korean Army recently organized a Future Hydrogen Mobility Seminar to kickstart this transition. The event, attended by key industry players and government representatives, marked the beginning of a collaboration to convert military vehicles and supplies to hydrogen-powered systems ahead of others in the sector. Hyundai and Kia are set to develop military-grade hydrogen vehicles, including a hydrogen refueling vehicle named the "H-Moving Station" by Hyundai and a hydrogen-powered vehicle capable of supplying 100 kW per hour by Kia. Additionally, Doosan Mobility is working on hydrogen drones, while Hyundai Rotem is focusing on hydrogen tanks and armored vehicles. The strategic move towards hydrogen energy is fueled by its higher power generation efficiency compared to conventional fossil fuels, as well as its ability to reduce noise, fumes, and heat emission, providing a stealth advantage in military operations. The Korean Army is set to begin pilot programs with hydrogen-powered light tactical vehicles and drones, emphasizing the importance of enhancing operational capabilities with cutting-edge technology.
