Mahle Powertrain's Hydrogen Fuel Project for Heavy-Duty Truck Engines

Mahle Powertrain is making waves in sustainable transportation with its ambitious initiative, Project Cavendish. This project has recently moved into the testing phase, aiming to harness hydrogen fuel for heavy-duty truck engines. With a substantial budget of £9.8 million ($12.2 million) funded by the UK government and supported by the Advanced Propulsion Centre UK (APC), the project is set to advance hydrogen combustion technology substantially.

Project Cavendish focuses on providing effective solutions and a clear upgrade path for heavy-duty truck manufacturers. The goal is to enable hydrogen combustion using current technology and infrastructure. Mahle Powertrain is leveraging its flexible testing facility in Northampton and its extensive experience with alternative fuels like hydrogen and methanol to create long-standing industry impact.

Hydrogen Combustion Engines: A Viable Alternative

“Hydrogen combustion engines (H2 ICE) are well suited to heavy-duty, long-distance applications that are hard to electrify,” stated Jonathan Hall, Mahle Powertrain’s head of research and advanced engineering. This statement underscores hydrogen's potential as a practical substitute for diesel engines in sectors where electrification faces hurdles.

Many industries are driven to adopt greener technologies as regulatory pressures increase. For instance, the EU has set revised CO2 standards for heavy-duty vehicles, requiring a dramatic 45% reduction in emissions by 2030, escalating to an ambitious 90% by 2040. In line with these regulations, the UK government is significantly investing £8.3 billion ($10.3 billion) into the hydrogen industry and up to £21.7 billion ($27 billion) for expansive infrastructure projects. This commitment indicates a major shift toward low-emission alternatives, positioning hydrogen as a key player in the future of transportation.

Collaboration for Innovation

Project Cavendish thrives on collaboration with key partners including Phinia, BorgWarner, Cambustion, Hartridge, and Mahle Powertrain. Together, they are working to develop advanced fuel-injection systems and turbocharging components readily adaptable to meet upcoming legislation. This diverse approach fosters innovation and consolidates expertise, which is critical in addressing complex engineering challenges.

The recently expanded facility in Northampton plays a crucial role in this initiative, with the capacity to support two tube trailers that ensure a consistent hydrogen supply. The facility's upgraded engine dynamometers can handle up to 900 kW/4,000 Nm, tailored to meet the demanding standards of heavy-duty testing. Additionally, in-house designed control systems and software enhance safety throughout the testing phases, thereby reducing risks associated with hydrogen handling.

Looking Ahead: Fueling a Sustainable Future

The testing phase of Project Cavendish represents a breakthrough for Mahle Powertrain and the hydrogen fuel sector. As pressures to lower carbon footprints intensify, the development of hydrogen combustion engines presents a practical solution for heavy-duty applications. This innovation enables manufacturers to utilize valuable insights gained from years of research and investment.

By championing hydrogen as an alternative energy source, Mahle Powertrain demonstrates not only its dedication to cleaner technologies but also its alignment with broader goals of achieving net-zero emissions. As the testing phase unfolds, industry experts are closely monitoring developments in this ambitious project, which could redefine the future of heavy-duty trucking.
