Critical materials for clean hydrogen

Hydrogen needs to grow seven-fold to support the global energy transition, eventually accounting for 10 percent of total energy consumption by 2050. A scaleup of this magnitude will increase demand for materials, such as aluminum, copper, iridium, nickel, platinum, vanadium and zinc to support hydrogen technologies—renewable electricity technologies and the electrolyzers for renewable hydrogen, carbon storage for low- carbon hydrogen, or fuel cells using hydrogen to power transport.
