A new Market Readiness Analysis by the European Commission, Transport & Mobility Leuven, Ramboll, and the University of Antwerp forecasts a significant rise in zero-emission heavy-duty vehicles on European roads by 2030. The report projects a scenario where 108,000 zero-emission buses and coaches could be operating, with battery electric vehicles (BEVs) taking the lead. This shift aims to address the urgency of transitioning to zero-emission technologies, especially in urban transport. With a focus on reducing emissions, the EU's policy framework mandates a 90% zero-emission rate for city buses by 2030 and 100% by 2035. The analysis envisions 534,000 zero-emission heavy-duty vehicles by 2030, primarily powered by batteries. While hydrogen vehicles are expected to have a smaller share, challenges remain in terms of energy demand, infrastructure needs, and the availability of hydrogen models, especially in the coach segment. The study highlights the faster electrification pace of short-haul operations compared to long-haul applications, where hydrogen's role is more prominent due to its energy density. However, uncertainties persist regarding the energy split between technologies and the dominance of hydrogen drivetrains in the market. Despite these challenges, the projected market shares align with EU's CO2 standards for heavy-duty vehicles and reflect ambitious climate policy targets, even though hydrogen's contribution is anticipated to be relatively smaller than in some optimistic forecasts.
