Green Rush host Matt Watson says "an awesome amount" of material will be needed for clean hydrogen applications, but guest Phillip Walter believes technology will provide solutions. On April 17, Watson recorded an episode of Green Rush with Walter, Executive VP of Business Line Hydrogen Systems for Heraeus, a major precious metals processor. The topic was the hydrogen economy and platinum group metals (PGMs). Walter said PGMs and hydrogen belong together because they have a unique position in geochemistry. Applications include electrocatalysts to produce hydrogen, Proton Exchange Membrane (PEM) electrolysis, electrocatalysts for electrolysis, the coating of bipolar plates or porous transfer layers to protect against corrosion, and removing oxygen from a hydrogen stream.
