Fibernex

Advanced Porous Materials and Coatings for Energy and Industrial Applications

Patent-protected 3D nanofiber technology

The Electrode Efficiency Challenge

Green hydrogen must compete with fossil fuels, but electrolyzer electrodes hold it back.

Low surface area: Today's nickel foams and plates have low surface area, limiting performance

Nickel dependency: Heavy reliance on nickel (an EU critical raw material) creates supply-chain risk

High production cost: Costly to produce, driving up CAPEX

The result: lower efficiency and a higher cost per kilogram of hydrogen produced.

Fibernex R&D work in the lab

Engineered for Scale, Designed for Efficiency

FIBERNEX develops next-generation porous materials that combine 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.

Up to 97% Less Nickel

Dramatically reduced material dependency and environmental impact

Up to 10% Efficiency Gain

A 5 MW electrolyzer stack gains ~45 additional tonnes of green hydrogen per year
