A groundbreaking technology has been developed by a research team in Busan, South Korea, to prevent temperature rise during high-pressure hydrogen charging, revolutionizing the efficiency and safety of hydrogen refueling systems. Led by Principal Researcher Dae-Hwan Kim at KIMM, the innovation utilizes an incompressible fluid to eliminate the need for cooling systems, reducing both refueling time and infrastructure costs. The method prevents adiabatic compression within the tank, enabling faster refueling and ensuring stable charging without temperature fluctuations. This advancement enhances user convenience, economic benefits for infrastructure operators, and long-term durability of hydrogen vehicles and infrastructure by preventing thermal degradation of tank components. The technology's potential applications extend beyond vehicles to large-capacity hydrogen containers in various sectors like ships, trains, and military vehicles, positioning it as a key driver for advancing the hydrogen economy and enhancing global market competitiveness. Principal Researcher Dae-Hwan Kim emphasizes the significance of this innovation in overcoming existing limitations and improving infrastructure efficiency. The research, conducted under a specific initiative, marks a significant step towards promoting hydrogen mobility and accelerating the adoption of hydrogen technologies on a global scale.
