The Hongqi Guoyue hydrogen bus has recently made its debut at the 2026 China International New Energy and Intelligent Connected Vehicles Exhibition. Drawing on its full-stack, independently controllable hydrogen technologies, the vehicle provides a brand-new solution for deep decarbonization in the transportation sector.

The reporter learned that the Hongqi Guoyue hydrogen bus is equipped with a solid-state hydrogen storage system with a capacity of 17.8 kg, and is paired with an 80 kW high-efficiency fuel cell system, a 170 kW high-performance electric traction motor, and a 30 kWh power battery. Together, these components form a highly efficient hybrid powertrain architecture combining fuel cell power generation with power battery supplementation, striking a balance between power output and operational economy.

Safety is the lifeline of hydrogen energy development. The Hongqi Guoyue hydrogen bus features an advanced solid-state hydrogen storage technology. Unlike traditional high-pressure gaseous hydrogen storage, it achieves stable adsorption of hydrogen through solid-state functional materials. Supported by this fundamentally innovative approach, hydrogen can be securely locked in even under extreme conditions such as vehicle collisions, eliminating leakage risks at their source and ensuring operational safety.

Additionally, the model draws energy from the electrochemical reaction between hydrogen and oxygen, with water as the only by-product throughout the entire process. It can reduce carbon dioxide emissions by 36.8 kg per 100 km traveled. Leveraging the synergy between high-efficiency fuel cells and hybrid powertrain energy management, the Hongqi Guoyue hydrogen bus boasts a combined range of 680 km, effectively addressing the pain point of insufficient driving range for hydrogen-powered vehicles. Going forward, FAW Group will continue to intensify research on core hydrogen energy technologies and advance the in-depth integration of green hydrogen with real transportation scenarios.
