such as wind and solar then storage and use after is clearly better for the environment as using it to fuel vehicles doesn't produce carbonized exhausts.

And yes, the icy roads problem can be solved, even if just keep salt/sanding the roads now in wihter.

Wouldn't it be great if the water exhaust could be gathered and saved, thus another water resource?

Curious about Hydrogen Advancements?... [View all] Think. Again. Nov 2023 OP

Seems good as long as the hydrogen produced yields more energy... brush Nov 2023 #1

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
