1. Seems good as long as the hydrogen produced yields more energy...

than what it takes to produce it. Is that the case?

If not there have been recent discoveries of deep hydrogen deposits in the Earth, like there are the many oil deposits already found for over a century. One in Africa and another in Australia.

That hydrogen is in just about pure form and does not have to be produced. Such deposits seem to be worth exploring.

One question, hydrogen fueled vehicles exhaust water, right? What happens in winter months? Will that exhaust free and make the roads slick and dangerous?

Thanks for your post. Hydrogen produced by green energy sources... brush Nov 2023 #3

Yep... Think. Again. Nov 2023 #5

The end user efficiency also matters. E.g. fuel cells are about 50% IIRC, gasoline ICE engines less than half that progree Nov 2023 #4

I've hear that debate before... Think. Again. Nov 2023 #6

What I'm talking about is if fossil fuels are used to produce the hydrogen progree Nov 2023 #7

I think that's another false argument... Think. Again. Nov 2023 #8

No, reducing fossil fuel use and reducing greenhouse gas emissions is not a "false argument" progree Nov 2023 #9

I did not say that... Think. Again. Nov 2023 #10

I'm just trying to get the point across that *IF* using dirty or partly dirty hydrogen actually reduces fossil fuel progree Nov 2023 #11

Okay, sorry if I misread you.... Think. Again. Nov 2023 #12
