Counterpoint: when traveling long distance, charging to 100% is pointless. 80% is much easier to achieve and can be done quickly.
The tesla model 3 is using an older 400v battery arch, not bad, but it does limit fast charging due to heat buildup. The newer EVs are now shipping with 800v packs, like the kia EV6, which can go from 10-80% in 18 minutes, or 217 miles. That's with a max of 230kW charging, compared to the model 3's 250kW. Larger batteries will be able to handle the full 350kW of current high power chargers. At that level we could easily be seeing 320 miles in 18 minutes, which is 4 hours of driving at 80 on the interstate.
High voltage batteries are rapidly changing how well charging works, and the industry is now looking into 1000-1200v batteries that can charge even faster.
Hydrogen's future will likely be in heavy duty equipment, like tractor trailers, where the weight and size of batteries becomes a major roadblock to implementation. For cars and light trucks, its highly unlikely, as the benefits dont really outweigh what EVs can do today. The Mirai really shows that off.
I have never said charging to 100%, I have only stated that at 5miles per kW, you would spend 149kW in 745miles (in ideal circumstances). Whatever the case, battery should have enough juice +20% on a top. So, back to that Kia that can do 18 minutes charge for 217 miles with 230kW charger, extrapolated comes back to the very similar figures I've already posted. The main reason for using 800V+ in newer vehicles is simply to reduce current (check under Ohm's law), however, at the end of the day you will still use 1kW of energy per 5miles in the best case scenario. Ever wondered why the long range electricity transmission is at 120kV AC?
As for Hydrogen cars, we are still in infancy there, Jason @ EngineeringExplained YT channel has explained quite well all the issues with hydrogen, however, until we find a cheap way for electrolysis, they are doomed, plus quite complicated design. Don't forget the hydrogen pumps infrastructure....
On the note of wind turbines, check UK's production of a few months ago when the wind stopped, fall back was.....guess what?.....natural gas generators, and the well kept secret is that those seems to be used more often than not. Green my lower backside.....
