If you want to consider lithium against hydrogen, that's fine: What's the environmental impact of hydrogen electrolysis, transportation, and construction of infrastructure to support it at a scale large enough to replace the ICE vehicle fleet? What kinds of materials need to be extracted to produce hydrogen fuel cells, and at what scale? How do those compare to the inputs for lithium ion batteries?
- N1H1L 5y agoThe sobering answer is that fuel cells also need a lot of problematic minerals too for catalysts. The most widely used H2 fuel cell catalyst is PtCo - so you still have the same cobalt problem there too.
