Truck manufacturers, facing pressure to reduce emissions, are embracing hydrogen combustion engines as a quick and cost-effective solution to transition from diesel. While electric batteries are too heavy for long-haul trucking and fuel cells remain expensive, hydrogen combustion engines offer a faster path to cleaner transportation.
Companies like Volvo, MAN, Daimler, and Cummins are investing in this technology, conducting pilot projects and planning commercial availability within the next few years. Hydrogen combustion engines offer a familiar, less disruptive technology that can leverage existing manufacturing lines and expertise, making the transition smoother.

However, challenges remain, including the need for emission filters, the development of smaller and safer hydrogen tanks, and the limited availability of green hydrogen. Natural gas or biogas combustion engines provide an interim solution, offering a lower-emission alternative to diesel while green hydrogen infrastructure is built.
The adoption of hydrogen combustion engines signifies a pragmatic approach to achieving cleaner transportation in the trucking industry, paving the way for a more sustainable future.
