Electrolyser Mesh · RuO₂-ready
GTX Electrolyser Mesh — NP1 precision mesh engineered as the substrate for ruthenium-dioxide coating. Independently validated at IISc Bangalore at 94.3% Faradaic efficiency under a 1,000-hour durability run. The platinum-substitution play for 100 GW European electrolyser build-out.
94.3% Faradaic efficiency. 1,000-hour durability. Platinum substitution at CAPEX parity.
Hydrogen-electrolyser economics are gated by catalyst cost. GTX RuO₂-coated NiMesh delivers catalyst performance equivalent to platinum at a fraction of the metal cost — at scale, that reshapes the CAPEX envelope of a 100-MW electrolyser stack. Independently benchmarked at the Indian Institute of Science Bangalore.

94.3% Faradaic efficiency on RuO₂ coat. Independently measured.
The Indian Institute of Science Bangalore benchmarked the RuO₂-coated GTX NiMesh at 94.3% Faradaic efficiency under sustained operation across a 1,000-hour durability window — within the performance envelope of platinum-coated substrates, at a fraction of the critical-metal cost.
For 100-MW electrolyser deployments, the catalyst-cost saving exceeds USD 2 million per stack under 2026 platinum benchmark pricing — before accounting for platinum-supply security risk.
