Reply to comment by esprit-de-lescalier in The race to make diesel engines run on hydrogen by FDuquesne

There's a truck like this working with batteries that almost doesn't need charging because it charges going full downhill and empty uphill.

You can't do that with hydrogen.

You also can't do that anywhere that doesn't have the mine at the top of a mountain.

Yes but many of them are in mountains, so it works.

Do you have more source on this article? "it consumes no energy doing it" and "eDumper produces 200 kwh of surplus energy every day" is impossible.

I don't think that surplus calculation is correct but that article gets the source from the CNN article which doesn't mention that surplus.

Either way, it's way more efficient than any other type of fuel.
