* [[?|Hydrogen fuel-cell vehicles]] would be unsustainable to scale up, because of the [[?|amount of platinum & palladium in the fuel cells]]. {{talk|This page needs to mention: Hydrogen ''production'' also requires these same metals but it [[?|can be done with much less of them]] and thus could probably be done sustainably.}} | * [[?|Hydrogen fuel-cell vehicles]] would be unsustainable to scale up, because of the [[?|amount of platinum & palladium in the fuel cells]]. {{talk|This page needs to mention: Hydrogen ''production'' also requires these same metals but it [[?|can be done with much less of them]] and thus could probably be done sustainably.}} | ||

Probably a lot less than the "renewables + energy storage" approach. I need to write a page explaining why.}} | * [[?|Hydrogen combustion vehicles]] don't have this problem, but their fuel-efficiency is lower.{{qn}} {{talk|How bad would this be an issue if renewables or nuclear were to be the main energy sources?}} {{talk|Discussion needed: How much hydrogen would have to be stored at any given time, in such a scenario (let's say if it's all produced through nuclear power)?
