Researchers from Tokyo City University and the National Traffic Safety and Environment Lab in Japan presented a paper at the SAE Powertrains Fuels & Lubricants meeting outlining plans to develop a multi-cylinder direct-injection spark-ignition (DISI) hydrogen internal combustion engine (ICE) for heavy-duty vehicles. The researchers are shooting to develop a hydrogen-fueled truck that offers the same level of performance that today's crop of diesel-fed big rigs provide.
Why focus on developing a hydrogen-fueled long-haul truck? Well, the research team insists that demand for a hydrogen-fed semi is, ahem, fueled by the need to slash air pollution and reduce global warming and suggests that a hydrogen ICE setup will do just that, stating:

A rig that emits only water. Yeah, that's some kind of progress.For small- and medium-sized trucks, diesel hybrid systems can be put into practical use. However, a battery or a hydrogen FC cannot be used in large-sized (heavy duty) trucks, which currently require a high power output. For the aforementioned reasons, the hydrogen ICE system development project for heavy-duty vehicles is promoted by the Next-generation Environmentally Friendly Vehicle Development and Commercialization Project (EFV21) of the Ministry of Land, Infrastructure, and Transport (MLIT) of Japan as one of the technical candidates that can greatly reduce the air pollution and global warming contribution of such trucks.
