In a groundbreaking move, MAN Truck & Bus plans to introduce 200 hydrogen trucks in 2025 powered by their innovative H45 hydrogen combustion engine. These trucks boast impressive environmentally friendly credentials, emitting less than 1 g of CO2 per tonne-km, with ranges of up to 600 km and quick 15-minute refueling times. What sets these hydrogen trucks apart is that they do not require heavy and costly lithium-ion batteries while still meeting the EU's criteria for zero-emissions vehicles. While hydrogen internal combustion engines (H2ICE) offer a promising solution for reducing emissions in challenging transport sectors, such as heavy-duty vehicles, the main obstacle to widespread adoption is the inadequate hydrogen refueling infrastructure. As of July 2024, there were only 1063 hydrogen refueling stations globally, significantly fewer than EV chargers, limiting the practicality of H2ICE technology. Moreover, H2ICE faces competition from battery electric trucks and fuel cell electric trucks, each presenting its own set of challenges and advantages in the transition to zero-emissions transport. Battery electric trucks struggle with the high cost and weight of large battery packs, while fuel cell electric trucks offer higher efficiency but require a different infrastructure. The future of transport seems to be moving towards cleaner and more sustainable options, with hydrogen trucks poised to play a significant role in reducing emissions and pioneering innovative solutions in the commercial vehicle sector.
