How is a "energy carrier" made from fossil fuels considered green?

Can’t be in its production via those processes and feedstocks. But it is in its application.

What makes sense to me is trying to get some engineering experience with hydrogen on the transportation side, while working on renewable mechanisms for generating the stuff. Solar, wind, bio.

Long-term reliance on natural gas as a feedstock for hydrogen simply won’t work, emissions issues aside. There’s a supply problem brewing there.

I think the hydrogen work is useful— but there are more immediate solutions for the short- to medium-term (conservation, efficiency, renewables, biofuels) that we could apply and that need funding and support.

Excellent book on this whole topic (at least, I liked it), is Joseph Romm’s Hype About Hydrogen.
