 ===Hydrogen fuel cells===
-Platinum, an extremely rare metal, is a key component of both fuel cells & electolyzers. Scalability is unlikely.{{qn}} There might be other options that involve only more abundant materials, but with somewhat less energy efficiency.

+Fuel cells need ''platinum-group metals'' (PGMs). Mineral reserves are sufficient but ''production'' is too low. Calculations are found here: [[Fuel cell vehicles#Rare minerals in the fuel cell]]
