- tyfon 7y agoThey're still considering hydrogen too, however hydrogen production/distribution is really inefficient and as of today not very carbon neutral [1]. When you count the whole supply chain it has about the same efficiency as a diesel. Pumping hydro electricity into a battery is much more efficient. I guess there would also be issues transferring the hydrogen to the trains, we already struggle (struggled, the H-stations for cars are closed after an explosion here) with multiple cars filling up in turn. The pumps would just freeze and you had to wait for half an hour to fill up the next car. [1] https://en.wikipedia.org/wiki/Hydrogen_production https://en.wikipedia.org/wiki/Hydrogen_production
