A new study has found that hydrogen is unlikely to play a major role in road transport even for heavy trucks. The study, conducted by the University of California, Berkeley, and the Lawrence Berkeley National Laboratory, looked at the potential for using hydrogen fuel cells to power heavy-duty vehicles such as trucks and buses.

The study found that, while hydrogen fuel cells have the potential to be more efficient than diesel engines, the high cost of hydrogen and the lack of a hydrogen infrastructure mean that hydrogen is unlikely to play a major role in the road transport sector in the near future.

The study did find, however, that hydrogen could play a role in powering electric vehicles, particularly in the case of heavy trucks. The study found that, while the cost of hydrogen is currently too high to make it a viable option for powering passenger cars, it could be a viable option for powering heavy-duty vehicles such as trucks and buses.

The study's authors say that the findings could have implications for the way in which the transportation sector tackles the problem of greenhouse gas emissions. They say that, if hydrogen is not going to play a major role in the road transport sector, then other options, such as electric vehicles, will need to be considered.
