The 10,000-mile test tour of hydrogen energy two-wheelers officially departed from Suzhou, Jiangsu Province on April 20, 2026. The caravan traveled westward along the G318 Sichuan-Tibet Highway, with the final destination being Lhasa, Xizang. Crossing plains, hills and plateaus, the team has completed multiple high-altitude road tests. Now the journey is progressing steadily, and the caravan is about to officially march into the hinterland of Xizang, entering the crucial final stage of the Xizang trip.

This journey has built an integrated support system of vehicle hydrogen supply + personnel oxygen supply. STECH FLUID provides independently researched and developed special hydrogen cylinder valves adapted to solid-state hydrogen storage systems throughout the process. With core performances of stable sealing, precise pressure regulation and resistance to extreme temperature differences, the company ensures stable hydrogen release and continuous energy supply for solid-state hydrogen storage devices. Meanwhile, linked with portable oxygen supply equipment, it takes into account both stable vehicle driving and personnel travel health, escorting the 10,000-mile journey in an all-round way.

01 Core Components Lay a Solid Foundation for Vehicle Power

The hydrogen energy two-wheelers participating in the expedition adopt solid-state hydrogen storage technology, and all vehicles are equipped with the company's independently researched and developed special cylinder valves (single valve with two parallel cylinders) adapted to the solid-state hydrogen storage system. As a key control component of the solid-state hydrogen storage system, this product has undergone both rigorous laboratory tests and long-distance road condition trials, showing excellent comprehensive performance.

   

The valve features exceptional sealing performance, perfectly adapting to the low-pressure plateau environment and eliminating the risk of hydrogen leakage from the source. Its precise and sensitive pressure control and stabilization design can accurately match the hydrogen release rhythm of solid-state hydrogen storage materials, flexibly adjusting the hydrogen supply state with altitude changes and driving conditions. This ensures the vehicle remains powerful and outputs steadily even in high-altitude areas above 4,000 meters.

   

Meanwhile, the product boasts outstanding resistance to vibration, hydrogen embrittlement and temperature differences, easily coping with the bumpy roads and huge temperature differences between day and night on the Sichuan-Tibet Highway. It operates stably without failures for long-term continuous use, providing solid and reliable core technical support for the hydrogen energy two-wheelers traveling long distances to Lhasa.

   

Relying on the advantages of solid-state hydrogen storage such as safety, stability and high hydrogen storage density, the vehicle does not require frequent energy replenishment and runs stably in low-temperature environments, highly meeting the needs of long-distance expeditions.

02 Professional Oxygen Supply Accompanies to Calmly Respond to Plateau Environment

   

Aiming at the travel challenges such as high altitude, thin oxygen and easy altitude sickness along the Xizang trip, the caravan is equipped with professional portable oxygen supply equipment throughout the journey to fully protect the health of the accompanying personnel.

   

This oxygen supply equipment is lightweight and compact, easy to carry during riding without burden and will not affect normal travel. Equipped with high-quality safety cylinders, it has a long-lasting oxygen supply endurance, fully meeting the all-day oxygen demand for long-distance riding during the day and rest at night.

   

The equipment supports multi-gear oxygen output adjustment with simple operation. Users can freely adjust the oxygen flow rate according to their physical conditions, effectively relieving altitude sickness and completely eliminating worries about traveling to Xizang, making the whole journey easy and stress-free.

   

   

03 Dual Protection for People and Vehicles, Hardcore Strength Demonstrated by Actual Tests

   

From Suzhou, a water town in the south of the Yangtze River, to Lhasa, the holy city of snow-covered plateaus, this 10,000-mile journey across almost all of China is not only a practical implementation of the hydrogen energy travel model based on solid-state hydrogen storage, but also a strength test of domestic core components adapted to solid-state hydrogen storage facing extreme plateau scenarios.

   

On one hand, the independently researched and developed high-quality cylinder valves control the whole process of hydrogen release from solid-state hydrogen storage, ensuring worry-free driving power. On the other hand, a complete oxygen supply scheme protects personnel's travel status and eliminates hidden dangers of plateau travel. The two-way protection for people and vehicles complements each other.

   

As the caravan is about to officially enter Xizang, the ongoing field road test will further verify the practical value of the company's special cylinder valves for solid-state hydrogen storage under extreme working conditions, fully demonstrate the company's independent research and development strength, help continuously expand green hydrogen energy travel scenarios, and accelerate the steady development of the hydrogen energy civilian industry.
