Ensuring Supply, Improving Quality, and Accelerating Speed! Sichuan Petrochemical's Hydrogen Energy Capacity Continuously Released, Boosting Chengdu-Chongqing Green Transportation Upgrade

Recently, the hydrogen supply capacity of Sichuan Petrochemical continued to climb, and the scale of market delivery achieved significant growth. Data shows that in the first five months of 2026, the company's ex-factory volume of fuel cell hydrogen products increased by 66.7% YoY, and the ample supply of high-grade hydrogen has laid a solid foundation for the popularization of hydrogen transportation scenarios in Sichuan and the construction of the Chengdu-Chongqing Hydrogen Corridor. At present, transport vehicles at the enterprise's hydrogen filling station are being dispatched in a normalized and orderly manner, with clean fuel cell hydrogen being continuously delivered to major hydrogen refueling stations across the province, ensuring stable energy use for regional hydrogen end-users.

With the rapid development of Sichuan's hydrogen energy industry, end-user demand for hydrogen in the market continued to expand. To meet the large-scale hydrogen supply gap, Sichuan Petrochemical launched a 24-hour uninterrupted loading operation mode since 2025. Through a series of optimization measures such as streamlining approval processes, refining loading standards, and strengthening full-process safety control, the company unblocked all bottlenecks across the entire chain from hydrogen production, filling to ex-factory delivery, achieving maximum supply efficiency. According to Wang Yongzhen, a local process engineer, the safety standards for fuel cell hydrogen filling are stringent. Through institutional reform and process optimization, the enterprise has now steadily achieved a daily average loading and dispatch scale of 7 trucks, fully ensuring stable and reliable hydrogen supply in the region.

Backed by stable hydrogen supply, Chengdu's hydrogen fuel cell buses have been deployed on a large scale and put into operation, becoming a landmark scenario for green and low-carbon urban travel. Wang Hui, a driver with over ten years of experience at Chengdu Public Transport Group, said that compared to traditional fuel buses, hydrogen buses offer faster power response, smoother start-up acceleration, convenient and efficient hydrogen refueling, and a single refueling can meet about two days of operational needs, with significantly superior overall user experience. Currently, Sichuan is making every effort to promote the construction of the Chengdu-Chongqing Hydrogen Corridor and Chengdu as a "Green Hydrogen Capital," with commercial application scenarios for hydrogen energy continuously expanding. As the core hydrogen supply base in Sichuan Province, Sichuan Petrochemical leverages its resource and location advantages, works with upstream and downstream enterprises in the industry chain, and has successfully established an integrated hydrogen industry system covering production, storage, transportation, and utilization, consistently supplying hydrogen to multiple PetroChina refueling stations in Sichuan and capable of meeting the refueling needs of over one hundred hydrogen vehicles daily.

Earlier in 2025, the production and sales volume of fuel cell hydrogen at Sichuan Petrochemical climbed steadily, and the company successfully fulfilled the critical task of hydrogen supply for the first Carbon-Neutral World Games, fully demonstrating the enterprise's supply capabilities and responsibility as a central state-owned enterprise, and further enhancing PetroChina's brand influence in the hydrogen energy field. While industrial benefits have grown steadily, the green and low-carbon value of the project continues to stand out. Since the fuel cell hydrogen project was put into operation, the enterprise has supplied a cumulative total of over 970 mt of hydrogen. It is estimated that this clean hydrogen can support hydrogen buses to drive a cumulative total of over 10 million kilometers, helping reduce regional CO2 emissions by over 10 kt, providing solid support for improving urban air quality and promoting the green transformation of regional energy.

Currently, hydrogen energy has been clearly identified as a new economic growth track for China, officially entering a new stage of large-scale and industrialized development. Going forward, Sichuan Petrochemical will continue to deeply cultivate the hydrogen energy sub-sector, continuously optimize production processes, increase capacity scale, improve the supply system, consistently deliver high-quality clean hydrogen, empower the high-quality development of the hydrogen energy industry in the Chengdu-Chongqing region, and use green "hydrogen power" to promote the coordinated development of regional economy and ecology.
