No it wouldn't.
How do you propse to get the hydrogen?
There is "green" hydrogen from electrolysis of water, using electricity, or "blue" hydrogen from steam reforming of natural gas, with capture of the CO2 produced as a byproduct: CH4 + 2H2O -> 4H2 + CO2
I'd have to find the episode, but in Top Gear Jeremy Clarkson gave such numbers for the UK to switch over. Even there they will need more power plants.
When I last checked the UK got 25% of its electricity from renewables. It may be slightly higher now. There's a long way to go. But we'll never get to 100% because of the intermittency problem. 50-60% is possibly the max, with the rest from nuclear as far as possible, plus a bit of gas for peaks.
So what? That is a very very small number. There are alternatives. Hydrogen is another technology. Sooner or later there will be no gasoline or petrol. What would those people do then?
Remember how I told you that in California one could take a road trip with hydrogen. Here is a video on one such trip:
Maybe yes, maybe no. The time to start to switch is now. We cannot afford to wait for perfect.
Spot-on. I get so sick of people putting up arguments for putting it off. We need to back a range of technologies and see which ones win out.
And I forgot to tell @TransmutingSoul that the technology that he wants already exists. There is another option that is being developed. There is hydrogen. They already have an upwards of 300 miles. And they refuel in about 5 minutes. It is just a matter of infrastructure. In California in the US and limited other areas around the world they are already rolling out hydrogen. Here is part two of a series of videos, I posted the first one for @Twilight Hue above:
Yes hydrogen may be a solution for long range and high energy requirements e.g. trucks. But of course it needs its own infrastructure, which is less well developed than electricity. One does not hear much about decarbonising road freight, actually.
You should realize that the price of technology drops as it is developed. Your complaints lack any merit at all.
I'm not disagreeing with the latter part. But part of the way the US has stalled on solving obvious issues is offloading them onto private sector when that's not even close to the largest problems. EVs are not even particularly carbon neutral here given not just the manufacture of the cars themselves, but the batteries and charging with fossil fuel derived electricity. I'll be more impressed by the imperative to switching to EVs when we've cleared the hurdle of having more than 20% renewable for the commercial sector which far outweighs energy consumption and emissions of private sector. (Wasn't kidding about Amazon. They produce more pollution and use more energy than some countries.)
Still doesn't make a difference to us because, again, like millions of Americans, there isn't infrastructure to support apartment EV use, especially for family vehicles. And US sprawling suburban homes is doing way more wasting than if we built a ton more high rises.
And the best is we will never run out of hydrogen. It's among the most abundant elements in the universe.
That's the thing that concerns me most.
