...but in my opinion, it doesn't really matter, we need to stop using fossil fuel-based energy so comparing the efficiency of other fuels to fossil fuels is pointless, we have to do it no matter what the efficiency differences are. It isn't like we can choose whether or not to continue using fossil fuels or use something else.

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

Unfortunately... Think. Again. Nov 2023 #2

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
