Trucks are already moving to electric.

It not going to happen overnight, and currently bans on new sales only are scheduled for like 2040, but they're likely to be brought forward as people get more confortable with the idea.

Starting with last mile delivery in urban areas, trucks are going electric today. And it's not initially about energy density, it's about the poisons and pollution they emit.

I'd claim it's all about economics. There are small trucks commercially available for the first time now that can move the volume of packages required. And they're cheaper to operate than ICE trucks, so companies are obviously and quickly switching. The marketing points are frosting on the equation!

Semi trucks will move 'forward' to electric when the technology becomes available.

So far it's not, the state of the art prototypes can not do the required job.

Maybe it will be something like fuel cells instead, who knows.

As I said, it's already happening.

Green Hydrogen will be part of the answer in the next 5 years or so, but it's not a blocker right now. There's plenty of semi trucks that have tasks that are within the current battery limits.

Green hydrogen is not green besides washing.

Green Hydrogen is going to be a big part of fixing the mess made by fossil fuels.

Blue Hydrogen and small Fuel Cell hybrids got pushed harder than they should have been by some oil and gas people, which left a bad taste in many people's mouths but, as long as it's not being used for something that you could do with mains electricity or batteries instead, Green Hydrogen is part of the solution. We need it for making chemicals and fertilizer and as an analog to pumped hydro storage.

A view on this from a anti-oil and gas angle is here:

Hydrogen cars, no. Hydrogen shipping, maybe. Hydrogen for chemical feedstocks, yes.

Green hydrogen right now is green washing. Clean hydrogen production is easy to do, but is more expensive than dirty hydrogen production.

When that equation changes (which it will do eventually), clean hydrogen production will win out and at that time, we'll need infrastructure to support it. The question is just: when will it happen?

Green Hydrogen became cheaper than dirty hydrogen in the US as of the recent Inflation Reduction Act:

> The cheapest cost of production for grey hydrogen in the world today comes in at a monthly average price of $1.71/kg in the US Midwest, according to Platts, with green hydrogen in the US Northwest coming in at $3.73/kg. Subtract the $3/kg via the tax credit, and that renewable H2 would cost a developer $0.73/kg to produce.

Good point - Didn't realize IRA addressed that! Though technically it hasn't been signed into law yet and I assume it doesn't go into effect immediately?

That’s a very bold claim with no support whatsoever.

Check how it is produced.

"Electrolysis from renewable energy" isn't an obvious boogeyman. That's essentially the definition of green hydrogen--maybe you're arguing that someone is selling counterfeit green hydrogen, but that's not an indictment of green hydrogen. In any case, would it kill you to spend a couple sentences explaining what you mean rather than trying to be all mysterious and making us guess?
