Several European big truck makers recently pledged to stop selling vehicles that emit emissions by 2040, 10 years earlier than originally planned. The alliance consisting of Daimler, Scania, Man, Volvo Trucks, DAF, Iveco and Ford signed a letter of commitment to phase out traditional internal combustion engines and focus on the development of hydrogen, battery technology and clean fuels. The move comes as European regulators and governments seek to phase out emissions-emitting vehicles in road transport. Under the EU's plan, carbon dioxide emissions will be cut by 50% by 2030. The UK has already said it will stop selling new gasoline and diesel vehicles, including hybrids vehicles, by 2035, and will hold further talks to try to end the use of diesel-powered trucks. At present, freight distribution is recognized as one of the most difficult areas to achieve low carbon. Although technologies such as electric vehicle systems are very suitable for urban delivery, long-distance transport vehicles still need diesel engines due to charging problems. The industry predicts that hydrogen power is more likely to become a future solution for large long-distance trucks. Previous studies have pointed out that despite the high cost and the difficulty in the construction of hydrogen station, hydrogen energy heavy truck is expected to become a hot spot in the development of new energy vehicles. The move by Europe's truckmakers could give the process a powerful boost.
