Smoltek can make green hydrogen economically viable

Smoltek’s technology for porous transport electrodes (PTE), developed in collaboration with Heraeus Precious Metals, has the potential to make green hydrogen economically viable. This is the conclusion drawn by the German tech channel Breaking Lab.

Watch Break­ing Lab – a Ger­man YouTube chan­nel with focus on new tech­nol­o­gy – when they dive into how there is a pos­si­bil­i­ty to scale up the pro­duc­tion of green hydrogen.

“We need green hydro­gen. But how can green hydro­gen scale up to an indus­tri­al lev­el when the cru­cial elec­trol­y­sis tech­nol­o­gy relies on one of the rarest met­als on Earth?”
Dr. Jacob Beautemps

This is the key ques­tion Dr. Jacob Beautemps asks him­self as he reviews the pre­req­ui­sites for pro­duc­ing green hydro­gen using Smoltek’s PTE—coated with Her­aeus Pre­cious Met­als’ irid­i­um oxide solution—in next-gen­er­a­tion PEM electrolyzers.
