Strategic update for Smoltek Hydrogen

Smoltek Hydrogen is developing Smoltek PTE – a proprietary porous transport electrode based on carbon nanostructures, which is intended to meet the requirements of next-generation PEM electrolyzers for the production of fossil-free hydrogen.

Smoltek Hydro­gen’s porous trans­port elec­trode tech­nol­o­gy has the poten­tial to sig­nif­i­cant­ly increase the cat­alyt­ic activ­i­ty of an elec­trolyz­er cell, while reduc­ing irid­i­um con­sump­tion by up to 95% – with­out com­pro­mis­ing per­for­mance. This tech­no­log­i­cal inno­va­tion is con­sid­ered a break­through with great sig­nif­i­cance for the pro­duc­tion of green hydro­gen and oth­er sus­tain­able ener­gy applications.

Smoltek Hydro­gen’s PTE tech­nol­o­gy has been rec­og­nized this spring by enabling hydro­gen pro­duc­tion with only 0.1 mg of irid­i­um per square cen­time­ter – while main­tain­ing per­for­mance in the elec­trolyz­er cell. The com­pa­ny has also ini­ti­at­ed col­lab­o­ra­tions to indus­tri­al­ize the tech­nol­o­gy togeth­er with Impact Coat­ings (man­u­fac­tur­ing), as well as with Her­aeus to opti­mize irid­i­um mix­tures with the aim of fur­ther increas­ing the amount of hydro­gen pro­duced per gram of iridium.
