While domestic and foreign enterprises are actively promoting the development of fuel cell technology, they have also not given up their attention to hydrogen internal combustion engines. Recently, foreign companies such as Deutz, Bosch, Toyota, MAN AVL、 Cummins, Kohler, Tata Motors, domestic enterprises Wuling Liuji, and FAW Jiefang have welcomed good news in the research and development of hydrogen internal combustion engine technology and product applications. The details are as follows: 
​
1. The joint venture project of Deutz hydrogen internal combustion engine signed and landed in Beijing Economic Development Zone 
In January 2024, the Zhongguancun Deutz hydrogen internal combustion engine joint venture project was signed and implemented in Beijing Economic and Technological Development Zone (Beijing Yizhuang). It is reported that the total investment of the project is 600 million yuan, and the implementing entity is a joint venture established by German veteran engine company Deutz and Zhongguancun Zhizhen Environmental Protection. The two will quickly combine hydrogen internal combustion engine technology with environmental protection systems, seize the demonstration application scenarios and markets of hydrogen energy.
​
2. Bosch will launch its first hydrogen powered internal combustion engine for trucks in 2024
On January 9, 2024, Bosch Germany announced plans to launch its first hydrogen powered internal combustion engine for trucks in 2024 to complement its existing fuel cell and power battery products. In May 2023, Bosch first announced plans to develop a hydrogen powered internal combustion engine, and then showcased the Ligier race car equipped with a 3-liter hydrogen engine at the Le Mans 24-hour endurance race in June. At present, Bosch has provided four different hydrogen engine injection systems on its official website.

3. German MAN launches MAN H4576 new hydrogen internal combustion engine
On November 27, 2023, German engine manufacturer MAN launched the MAN H4576 new hydrogen internal combustion engine. This internal combustion engine is developed based on the D3876 diesel engine, with an output power of up to 368 kilowatts and a displacement of 16.8 liters, providing a wide range of possibilities for decarbonization of agricultural machinery. K ä ssbohrer Off Road Vehicle Company is a pioneering enterprise that collaborates with MAN Engine Company to develop zero emission drive for off-road vehicles. The upcoming Pisten Bully 800 model has already reserved space in the design for the placement of the MAN H4576 hydrogen internal combustion engine and will provide corresponding interfaces. 

4. Toyota Australia releases HiAce H2 Engine hydrogen internal combustion engine prototype car
In November 2023, Toyota Australia showcased a prototype HiAce H2 Engine equipped with a hydrogen internal combustion engine, primarily used for short distance transportation. And Toyota Australia executives have revealed that in the future, the HiAce H2 Engine technology will be used in Land Cruisers and other large passenger cars, and may also be paired with hybrid power.

5. Wuling Liuji's first independently developed 4M20H hydrogen internal combustion engine successfully ignited
On October 26, 2023, Wuling Liuji successfully ignited its first independently developed 4M20H hydrogen internal combustion engine. This product adopts a 4-cylinder 2.0L engine with strong power and high efficiency performance characteristics, with a maximum power of 70kW/5600rpm and a maximum torque of 130N · m/4000rpm. 

6. FAW Jiefang plans to deliver hydrogen internal combustion engines to customers by 2023
On October 16, 2023, FAW Jiefang announced that it will continue to increase research and development investment in hydrogen internal combustion engines. After the first ignition in 2022, it has been promoting development work and has entered the stage of vehicle trial production. It is planned to deliver to users for demonstration operation in March 2024.

7. Austrian AVL has developed a hydrogen internal combustion engine for racing cars
On October 16, 2023, the racing department of Austrian automotive supplier AVL developed a hydrogen engine for racing. In static testing, the 2-liter turbocharged engine produced a top-level power measurement of 305 kilowatts at an engine speed of 6500 revolutions per minute. This output will match the power of Bugatti and Ferrari. 

8. Cummins X15H hydrogen internal combustion engine will be used in the Terex mixer truck
In October 2023, Jim Nebergall, General Manager of Cummins Hydrogen Engines, detailed in a statement the collaboration with Terex Advance Mixer, end-user Edge Materials, and hydrogen producer PCC Hydrogen.
This end-to-end demonstration project will test Cummins' X15H hydrogen internal combustion engine on the Terex front dump concrete mixer truck at construction sites and important infrastructure projects. David Grabner, General Manager of Terex, added, "Due to the high energy demand and long working hours, it is difficult for concrete mixer trucks to achieve decarbonization. Therefore, engine manufacturers believe that such heavy-duty applications are the entry point for H2 internal combustion engines to surpass zero carbon alternatives such as hydrogen fuel cells and battery electric systems

9. Kohler releases new direct injection hydrogen (KDH) engine
In November 2023, American engine company Kohler released a new direct injection hydrogen (KDH) engine based on the KDI 2504 TCR diesel engine. It is reported that this 4-cylinder KDH engine used for off-road machinery is consistent with traditional diesel engines in terms of cabin layout, size, power output device, and performance. Its maximum output power is 55.4 kilowatts (74 horsepower) and the speed is 2600 revolutions per minute; The maximum torque is 315 Nm (232 pound feet) and the speed is 1500 revolutions per minute.

10. India's Tata Motors launches hydrogen internal combustion engine and hydrogen infrastructure research and development laboratory
In October 2023, India's largest automotive company Tata Motors announced two state-of-the-art research and development facilities to fulfill its mission of providing sustainable mobility solutions.
