Hydrogen Production Pathways
Electrolysis, thermochemical, biological and other production routes—and when platinum is relevant.
What this topic covers
Electrolysis, thermochemical, biological and other production routes—and when platinum is relevant.
Core energy-system ideas
Hydrogen can be produced by multiple pathways, not all of which use platinum.
PEM electrolysis is one important platinum-related pathway because platinum is used at the cathode.
Other production routes may use different catalysts or no platinum at all.
Important tradeoffs
Fuel cells, electrolyzers, storage and delivery equipment should be separated when estimating material demand.
Material and performance evidence
Energy-system performance depends on catalysts plus membranes, transport, power electronics, thermal systems and duty cycle.
Lifecycle perspective
Hydrogen and pressurized equipment require professional engineering and operating controls.
