【Major Industrial Equipment in the Chemical Industry】352 — China’s first commercially available hydrogen internal-combustion engine truck

Against the backdrop of global carbon neutrality, hydrogen fuel cell trucks have become the new favorites in the industry, while hydrogen internal combustion engines, as a valuable supplementary solution, are also gaining attention from the industry. According to information from the industry website TruckHome, almost all major European commercial vehicle manufacturers are currently paying attention to hydrogen engines or have already begun researching their feasibility; a hydrogen engine alliance comprising 22 companies, including manufacturers and suppliers of key components, has been established. Industry analysts believe that, considering reliability, cost, and economic efficiency, hydrogen internal combustion engines represent a highly attractive zero-carbon powertrain technology solution for commercial vehicles, as well as an important approach to reducing dependence on oil. Reporters from the Daily Economic News have observed that, compared to the plans of major foreign manufacturers, the domestic heavy truck market is likely to see faster commercialization of hydrogen internal combustion engines.

10 kilograms of hydrogen can enable a drive of 100 kilometers. Under the \"dual carbon strategy,\" the use of hydrogen energy has attracted significant attention from all sectors. A responsible official from Weichai Power explained that hydrogen internal combustion engines have three key advantages: first, they can be developed using the existing internal combustion engine manufacturing infrastructure; most of their components are compatible with those used in current mature internal combustion engine products, which greatly reduces the development time and facilitates industrialization ； Secondly, it has the potential to meet stringent emission regulations without the need for post-treatment systems; such systems can be eliminated or simplified, resulting in a significant advantage in terms of product cost ； Third, it adopts a traditional combustion-based power generation mode, which requires a lower purity for hydrogen fuel and has good fuel adaptability. “The vehicle on display can carry 30 kilograms of hydrogen, and it can travel 100 kilometers with 10 kilograms. ”The official told the reporter.

In terms of hydrogen production costs, when this figure drops to 35 yuan per kilogram, the operating cost of hydrogen will be comparable to that of diesel; currently, in Shandong Province, it is mostly between 50 and 60 yuan per kilogram. In terms of transportation costs, hydrogen refueling stations currently incur the same costs across different application scenarios. Those that are designed with a store in front and a production facility behind can minimize transportation costs to the greatest extent possible; in other scenarios, efforts are made to shorten the transportation distance, with the current limit for storing and transporting hydrogen being no more than 150 kilometers. Taking Shandong as an example, hydrogen refueling stations along the Jiqing Expressway in Shandong have basically formed a network, further reducing costs. It is understood that Weichai Power began to work on hydrogen internal combustion engine technology in 2018, achieving breakthroughs in key core technologies and their commercial application; it has now reached an effective thermal efficiency of 41.8%, which is at an internationally advanced level. The models launched this time incorporate a number of proprietary technologies in terms of performance development and related applications. They use precise hydrogen injection control technology to ensure a flexible and accurate supply of hydrogen fuel, thereby fully meeting the engine’s requirements under varying operating conditions ； High-efficiency supercharging and lean combustion technologies are employed to address the issue of abnormal hydrogen combustion, ensuring the engine operates smoothly and efficiently ； It adopts Weichai’s proprietary ECU system, enabling intelligent control and autonomy, while ensuring customized development of control strategies ； Technological expansion based on existing gas engine product platforms can accelerate commercialization.
