Sankey diagrams illustrating the renewable electricity input needed to provide 1 MJ to the Light-duty vehicule wheels for 4 powertrain options: (A) battery electric, (B) hydrogen fuel cell, (C) internal combustion engine on e-gasoline, and (D) e-gasoline with direct capture.

and how to understand this shit?
It’s so obvious, but so many still think the future will be ridiculous inefficient alternatives
And I still think batteries are not the future, but hydrogen is, for the simple reason that commercial vehicles like trucks can’t spend 40-60 minutes recharging every 2-300km when their payload is already significantly smaller than their combustion powered brethren. A hydrogen electric truck will have a similar range, but importantly, a higher payload and it could be back on the road in less than 10 minutes.
Electric vehicles are great, but the environmental cost of mining for battery materials is large. I hope we are able to find cleaner alternatives for lithium-based batteries. AFAIK there are some projects using lignin and other renewable materials.
Interesting.
I wonder how much power would be added if the production of batteries for electric vehicles is included
EV basically make use of all the energy they consume
that’s what Elon Musk has always said. Battery Electrics are the most efficient vehicles. However Hydrogen Fuel Cell may find its way with Boats, Train, Agricoltural Tractors and even Trucks since the battery represent a problem for these large vehicles.
I will consider an EV if it can do 600-800 km on one charge and take 3-5 minutes to go to 100% like in my diesel car
Oh and also it not costing an arm and a leg and not degrade the battery over time so i dont get boned with the battery buying used
