Mercedes Unveils Off-Road Truck with Hydrogen Combustion Engine

German automaker Mercedes-Benz has unveiled its first demonstrator vehicle for a hydrogen combustion engine, which is based on the off-road truck Unimog.

The project, called WaVe, is a research and development program funded by the German federal government that brings together 18 partners to explore the potential of hydrogen as an alternative energy source.

The hydrogen combustion engine, provided by Keyou, has been installed on the Unimog as part of the second phase of the project. The aim of the WaVe project is to explore the potential of hydrogen combustion engines to perform the tasks of conventional diesel engines. The Unimog is a suitable test vehicle for this purpose because it requires high efficiency, power, and high payloads at the same time.

The hydrogen combustion engine is seen as a viable alternative to battery-electric drive and hydrogen-based fuel cells for vehicles that require high payloads and efficiency. “As space is limited, the installation of a purely battery-electric drive or hydrogen-based fuel cells would be difficult,” explains Mercedes-Benz.

The first test phase of the hydrogen combustion engine was completed successfully in autumn 2022 on the test bed. The engine, fuel tank, safety, and monitoring systems were installed on the Unimog at the end of the year, allowing the first driving tests to be carried out. The prototype will be equipped with a system in the second quarter of 2023.

The WaVe project aims to explore the use of hydrogen as an alternative energy source for transportation. Hydrogen has the potential to reduce emissions and increase efficiency, making it an attractive option for manufacturers and policymakers alike. The project partners plan to study other techniques such as hot hydrogen combustion in the piston engine by the end of June 2024.

While the use of hydrogen as an energy source for transportation is still in the experimental phase, the WaVe project is an important step towards the development of viable alternatives to fossil fuels. The use of hydrogen combustion engines could be a game-changer for industries that require high payloads and efficiency, such as the transportation and logistics sectors.

However, there are potential challenges that must be overcome before the widespread adoption of hydrogen as an energy source. These include the high cost of production and storage, as well as the lack of infrastructure for distribution and refueling. Nonetheless, the WaVe project is a promising development in the pursuit of sustainable transportation.
