A standard European 400 kV power line can transmit more than 1 GW over hundreds of kilometers. Upgrading the grid will not be cheap, but the required technology has been well established for over a century.
- TheLoafOfBread 4y agoWell you kinda can't have 400kV in a highway.
- fsh 4y agoWhy would you? The lines go next to the highways, where they have always been.
- iso1631 4y agoMany 400kV lines run alongside highways. Or you could put up wires on highways which means trucks can charge as they drive along. Germany, Sweden, the UK have been doing trials on this https://www.carscoops.com/2021/07/uk-approves-e-highway-scheme-installs-overhead-wires-on-motorway-to-charge-trucks/ https://www.carscoops.com/2021/07/uk-approves-e-highway-sche... "An academic study suggested the e-highway system covering all but the most remote parts of the UK could be completed by 2030 at a cost of £19 billion (£26.4 bn)," In context that's about the same cost as Crossrail.
