Propane injection works a treat with diesels. In blended use, due to how cheap propane is, you can save a whole lot.

You're going to spray past the tail-pipe? That means the least improvement per gallon of water used.

Simple, un-metered, and erratic.

Heat, true. Which is why the original suggestion was for intake injection. Injecting a water mist right after the air intake or before the turbo is best.

So the idea is that I get the hydrogen injection implemented first, and then make sure that much less (preferably none) of the generated air pollution gets into people's lungs.

First, do what's proven to work.
Understand how and why it works.
Nobody injects water into the exhaust. There's a good reason for that. A lot of racers and diesel tuners use it. There's also a good reason for that.
Also, a water injection system is already half of what you need to transition to a hydrogen system, if you still choose to go there.
And it works. It really works. I've had two or three installed. Race teams use them. Manufacturers have experimented with them, but don't use them because they don't trust consumers to refill the water properly.

Hydrogen is a waste of time on a diesel.

Those who sought to replace one combustible by another instead of going electric.

Too bad most electrical power comes from burning something.
That is correct, just substitute burning one thing for something else, some where else.

If I had an EV I'd get solar panels for my roof.
In my situation, with a non-ideal roof, having an EV would make having home PV panels cost effective.
My next car will be an EV or a plugin hybrid.
Combined with the home PV panels it will save instead of cost energy.
