Cummins Inc., a global leader in power and technology, has launched a groundbreaking turbocharger engineered exclusively for H₂ internal combustion engines (H2 ICE). This innovative development represents a major leap forward for heavy-duty commercial vehicles in Europe and underscores Cummins’ commitment to pioneering sustainable transport solutions.

The new H₂ turbocharger, developed by Cummins Components and Software (CCS)—a division of the company’s components business segment—has already secured a significant contract with a major European original equipment manufacturer (OEM). This collaboration solidifies Cummins’ position as a front-runner in H₂-powered technology and its strategic role in accelerating the shift toward cleaner transportation.

Designed specifically for H2 ICE platforms, the turbocharger is intended to power the first H₂-fueled heavy-duty engines for on-highway use in the European market. The product meets increasing demand for environmentally responsible solutions while offering reliable, high-performance capabilities. Recognized by the European Union as a zero-emissions technology, H2 ICE presents a promising transitional pathway to full decarbonization, aligning with forthcoming Euro VII emission regulations.

At the heart of this innovation is a variable geometry turbocharger tailored to the distinct demands of H₂ combustion. Featuring custom-designed aerodynamics and advanced prognostic capabilities, the unit delivers optimized efficiency and durability even under H₂’s complex operating conditions. This breakthrough is a core element of Cummins’ “Destination Zero” strategy—an ambitious roadmap to achieving net-zero emissions through industry-wide collaboration and technological advancement.

Key Features of the H2 ICE Turbocharger include:

• Custom aerodynamics optimized for H₂-fueled engines
• Advanced performance monitoring through integrated prognostics
• Full compliance with Euro VII emission standards.

Developing a turbocharger for H₂ engines posed several technical challenges. Cummins engineers had to rework the aerodynamic profile to adapt to variable lambda values, handle increased water output from H₂ combustion, and mitigate the metallurgical effects of H₂ exposure. Despite these obstacles, the company succeeded in delivering a reliable, efficient, and emissions-compliant turbocharging solution for the next generation of heavy-duty vehicles.
