Zero-emissions trucks are becoming more and more relevant in the transportation industry as a way to reduce emissions and improve sustainability. These zero-emission trucks can either use electric powertrain architectures based on fuel cells or batteries, or internal combustion engines with zero-emissions fuels and could provide a range of advantages over traditional diesel-powered trucks. They produce no emissions locally, which means they are better for the environment and the health of people living near busy roads. If battery or fuel cell technologies are considered, they have the potential to be cheaper to operate and maintain, with lower fuel costs and fewer parts that need to be replaced but may be limited in terms of range. In this scenario, the zero-emission trucks are evolving by embracing new concepts such as multi-fuel powertrains which may offset the charging times and low range of battery-electric options, as proposed in the ALL-IN Zero project in the frame of Horizon Europe. The short-term horizon of zero-emissions trucks is uncertain, and all the related technologies must be put together to identify the best roadmap to achieve carbon neutrality.
