> what are they producing Hydrogen with and how is it more efficient energetically and emission wise? Even if it is just Blue hydrogen being burnt here, the splitter plants can have some carbon capture in it which would be impossible to install on a moving train (beats diesel and also direct LNG burning). That said, with trains there's no real argument against electrification. The wheels have been electrically driven for a few decades now. It's not like they need to come up with motors or work out batteries.
