Hmms. 2k km isn't bad, but i don't consider this amazing either: my 12-year old big and heavy car can do 1300 km on a full tank. Sure, that's in ideal condition

Hmms. 2k km isn't bad, but i don't consider this amazing either: my 12-year old big and heavy car can do 1300 km on a full tank. Sure, that's in ideal conditions, but so is this. And there is plenty of simple improvements that would make my car more efficient (weight & aerodynamics mainly).
2k isn't bad, but it's something that ought to be almost achievable with a modern and optimized ICE car as well nowadays.
- pengaru 4y agoHydrogen combustion doesn't produce co2, optimize a petrol-fueled ICE all you want and it's still a problem WRT emissions. I think the assumption is that hydrogen fuel would be produced via "green" electricity sources like wind/solar/nuclear.
- gibsonf1 4y agoThere is that subtle issue of how do you get hydrogen.... Takes energy to make it.
- bombcar 4y agoYou can just break apart water with very small tiny little hammers. Finding the miniature dwarfs to do this is the tricky part.
- hijinks 4y agogotta feed them though so still energy needed
- pengaru 4y agoTakes energy to mine+process the contents for and charge batteries too.
- FullyFunctional 4y agoBatteries have 1000+ cycle life time (LFP batteries even more) and charging is very efficient. Not at all comparable.
- arghwhat 4y agoA full hydrogen tank contain in the area of 5kg of fuel, which is a lot less fuel than the 70-100L of fuel your car presumably has on board. A normal range for cars these days is 500-900km on a 40-60L tank, as carrying excessive fuel is bad for efficiency. 2000km is a very impressive metric, all things considered.
- Beldin 4y agoFair enough - though my car "only" has a 60L tank, so I'd expect much better for modern cars (driven in optimal conditions).
- walnutclosefarm 4y agoA Toyota Prius in good conditions gets better than 4 liters/100km mileage - so you only need an 80 liter, or 20 gallon, tank to make it a 2000km vehicle.
