FIBERNEX develops next-generation porous materials combining engineered nanofiber substrates with thin, uniform metallic coatings - delivering significantly higher active surface area than conventional alternatives. Applied to green hydrogen: a patent- protected 3D nanofiber mat coated with a thin nickel layer via low-cost electroless plating replaces bulky nickel-foam electrodes, cutting nickel use by up to 97%, boosting efficiency by up to 10%, and lowering production cost by up to 75%.
