As the world works to cut carbon emissions and tackle climate change, hydrogen stands out as a promising solution. Providing a clean and efficient alternative to fossil fuels, it produces only water when used in fuel cells or combustion engines, making it vital for reducing greenhouse gases.
Yet, several challenges hinder the widespread use of hydrogen. These include high production costs, lack of infrastructure, storage and transport issues, and flammability risks. Regulatory support is also often lacking. Despite these hurdles, advancements are driving a hydrogen revolution towards sustainable energy.
For those seeking a partner in reducing commercial vehicle emissions with hydrogen power, Eaton offers advanced solutions for hydrogen fuel cells and combustion engines across all powertrain types.
Efficient hydrogen recirculation is essential for optimizing fuel cell performance, and Eaton’s hydrogen recirculation blower (HRB), powered by its proven TVS technology, ensures reliable operation—even in challenging conditions such as cold starts.
Beyond hydrogen recirculation, maintaining an effective anode loop requires additional components for purging and water management. Valves and water separators can be integrated with TVS technology, helping to create a complete anode loop system. Together, these components enhance fuel cell efficiency, improve stack responsiveness, extend system longevity, and ensure optimal operating conditions.

H2 ICE engines require significantly more air than diesel engines for low NOx formation during the combustion process. Eaton’s TVS supercharger provides the ideal solution for this challenge. It can produce instant air flow at low engine speeds, disengage to reduce parasitic losses when not needed, and complement a turbocharger in turbo-super configuration. Explore how Eaton’s TVS supercharger can improve your H2 ICE engine performance.
“H2 Internal Combustion Engines, characterized by low ignition energy, are prone to an increased risk level of pre-ignition, even if they run lean. In powerful applications, where a stoichiometric mixture is desired, very high gas temperatures and pressures are expected and knocking may occur. Eaton, a global leader in engine valves, has developed its next generation of hollow valves specifically for commercial vehicles and hydrogen-powered applications. The innovative design of the new hollow valves lowers temperatures (up to 100°C temperature reduction on the combustion face compared to a solid valve with similar geometry and material), which reduces the risk of uncontrolled combustions and allows the use of more cost-effective materials. Learn how Eaton’s hollow valves can benefit your H2 ICE engine design.”
H2 ICE engines need more engine braking capabilities due to their low compression ratio. Eaton’s 1.5 stroke engine brake delivers 40% more braking power at low speed than a conventional engine brake. Testing has shown that the combination of an Eaton TVS supercharger and 1.5-stroke engine brake provides additional braking power of up to 20%, while lowering peak temperature at injector and turbine. Find out how Eaton’s 1.5 stroke engine brake can enhance your H2 ICE vehicle safety and efficiency.
