The automotive industry is undergoing a transformative shift with the rise of hydrogen internal combustion engines (H2 ICE). Interact Analysis foresees a significant increase in H2 ICE car sales, reaching approximately 220,000 by 2035. This technology not only addresses CO2 emissions but also leverages existing manufacturing expertise to produce environmentally friendly vehicles. Despite benefits, challenges such as limited hydrogen infrastructure and high fuel costs pose obstacles. However, industries like mining and construction stand to gain from H2 ICE vehicles due to their compatibility with impure fuels and high power output. While H2 ICE vehicles may not dominate the market, they offer specific advantages for off-road and heavy-duty applications. Key players like BMW Group and Volvo Trucks are actively investing in H2 ICE projects, indicating a promising future for this technology. Although H2 ICE may not replace traditional technologies, it is set to carve a niche in the green mobility landscape, contributing to a diversified and sustainable transportation ecosystem.
