Why do the Germans even concern themselves with electrolytic hydrogen, which I believe isthe method they expect to use to make the hydrogen for the new trains? There are multiple issues, but I think the bottom line is that they are anticipating a day when their grid will be powered totally by renewables and will be 100 percentcarbon-free. Then their electrolytic hydrogen will also be 100 percent carbon-free and ‘renewable,’ but they have a long way to go to get there.
