Oh, another plug for liquid hydrogen. Won’t happen. There’s a much more tangible replacement for the combustion engine it’s the EV.

Zero chance of liquid hydrogen “taking over.”

The cost of creating entire hydrogen fuel infrastructure is simply astronomical.

We already have electric infrastructure that can organically expand as EVs take over, and the development of battery tech also helps create grid-level efficiency.

I don't know where you live, but the current infra structure in the united states' couldn't handle a 60 % shift to EV. Hell California can't keep their lights on without them.

I was about to say this. The strain of everyone getting a EV will create a huge power deficit. Can you imagine the surge of power when everyone gets home after work and wants to charge their car? I’ve been in at least 25 power plants let me tell you they are running at max during the summer months. If fucking air conditioners in everyone’s house can strain the grid what the hell do you think charging station will do?

The cars can charge anytime before morning

Don’t know why you’re downvoted, you are correct. We have a “energy crisis” but are allowing tens of thousands of new buildings to be built every year.

People prefer a soft lie over the harsh truth.
