Yeah, electrification costs are estimated in the 2004 at 25% of construction costs, 16.7% of total costs. But I doubt Primove would work on highspeed applications - you'd just be carrying on way too many batteries-capacitors (google was no help in answering this). You're looking at 20 kwh of consumption per kilometer, without the weight of carrying around the storage system and dealing with more than 60 kwh per minute of energy use.



If you could get a hydrogen set with the ability to generate that much power, lets say 4 MW, you'd do the trip on less than 300 kilos of the stuff. The waste heat of capacitors, batteries, or fuel cells would be considerable too and take lots of effort to deal with. In comparison, the hydrogen Coradia iLint's diesel version has a power requirement of about 1/10th the amount.



Easiest just to order a trainset with a jet train style solution, and if a better option comes along, replace it.
