China Yuchai International Limited, one of the largest powertrain solution manufacturers through its main operating subsidiary in China, Guangxi Yuchai Machinery Company Limited (Yuchai), announced that 50 green energy buses equipped with Yuchai Xingshunda H₂ fuel cells debuted at a ceremony in Beijing.  Yuchai Xingshunda is a 65% owned joint venture of Yuchai established in 2022 with Beijing Xing Shun Da Bus Co., Ltd. for the development, manufacturing and sale of fuel cell powertrain systems as well as core fuel cell power system components.

These first 50 Suzhou King Long 12-meter H₂ fuel cell buses commenced their commercial operations powered by 30 units of 82 kW and 20 units of 125 kW Yuchai Xingshunda H₂ fuel cell systems. This Yuchai 82-kW H₂ fuel cell system generates an energy efficiency higher than 43% and enables a service life of more than 15,000 hours. It is highly suitable for buses, light-duty trucks, passenger vehicles, construction machinery and other applications. The Yuchai 125-kW H₂ fuel cell system features a proprietary metal plate stack to reduce H₂ consumption and has an energy efficiency above 45%. Together with Yuchai's advanced intelligent energy management programs and algorithms, the 125-kW system enables optimal energy distribution and utilization, improves the overall system performance and safety, and prolongs the powertrain lifespan to more than 15,000 hours. Yuchai's 125-kW H₂ fuel cell system is designed for semi-trailers, cargo and dump trucks, passenger cars, and construction machinery.

These Yuchai new green energy powertrain products are important to meet the national double carbon goal. Compared with traditional internal combustion engines (ICEs), H₂ fuel cell powertrain systems use the electrochemical reaction of H₂ and air to replace the combustion process in traditional ICE vehicles. These new products have demonstrated many technical advantages such as high energy efficiency, zero emissions, low noise, and high-power density. These two H₂ fuel cell powertrain systems not only meet the national technical guidance requirements for H₂ power, but also source all components and parts domestically in China.

Green and low-carbon transportation is one of the top Ten Actions to Peak carbon. In recent years, construction of China's H₂ energy industry has developed at an accelerated rate. While continuing to develop reliable and leading traditional power engines, Yuchai has also embraced investments in new energy powertrain development. Using Yuchai Xin-Lan New Energy Power Technology Co., Ltd as a platform, Yuchai promotes strategic cooperation to strengthen core competences, and build expertise in creating new energy systems for a wide range of operating scenarios. 

Mr. Weng Ming Hoh, President of China Yuchai, said, "China's H₂ energy and fuel cell industry are poised to enter a period of accelerated growth. These 50 H₂ buses commencing operation are the first product implementation of Yuchai Xingshunda's core technologies in the marketplace."
