re: Stated at CERAWeek: Hydrogen adoption will cost Europe, US more than $1 trillion

FWIW, this is comparable to or probably even less than the collective costs of new battery factories and charging stations for BEVs, which is also infrastructue, and that does not include power grid upgrades that will also be needed. The article is just throwing a big number at you in the absence of anything to compare it to for the OMYGAWD reaction it will draw.

I'll leave the hydrogen vs BEV vs fossil debate alone for now, but as with most things technological, there is no one silver bullet. We will probably have a mix of techs in the end.
