Why NP1 Nickel Wire Is Critical for Green Hydrogen
Green hydrogen is the single largest decarbonisation lever remaining in the global energy transition toolkit — and the single largest cost barrier is the catalyst material inside the electrolyser. Platinum-group metals, today's reference electrocatalysts, cost USD 30,000–50,000 per kilogram and are geopolitically concentrated. The only pathway to hydrogen produced below USD 2 per kilogram is a cheaper, more efficient catalyst material.
NP1 nickel mesh with a ruthenium oxide (RuO₂) coating has demonstrated 94.3% Faradaic efficiency in Oxygen Evolution Reaction (OER) testing at the Indian Institute of Science, Bangalore — exceeding platinum-based systems (85–90%) while reducing material costs by approximately 95%. Nickel itself is priced below USD 1,000 per kilogram.
Each 1 MW electrolyser built with NP1 mesh catalysts rather than platinum-group alternatives saves approximately USD 200,000 in material costs while simultaneously delivering a 5–10% efficiency improvement on hydrogen output. At EU Green Deal scale — 100 GW of electrolyser capacity targeted by 2030 — this economic advantage compounds into tens of billions of dollars of system-level savings.

Market Size and Growth Drivers
The hydrogen catalyst market is currently sized at USD 0.5–1 billion but is the highest-CAGR segment on this platform at approximately 25% per annum. Three mandates drive the expansion:
- EU Green Deal: binding target of 10 million tonnes of green hydrogen by 2030 and 100 GW of electrolyser capacity installed within European borders.
- US Inflation Reduction Act: production tax credits up to USD 3/kg for clean hydrogen, making electrolyser economics decisive.
- Asian industrial hydrogen mandates: Japan, South Korea, China, India all targeting multi-GW hydrogen infrastructure within the decade.
The pathway to the sub-USD 2/kg green hydrogen price point required for hard-to-abate industrial decarbonisation runs directly through catalyst material cost reduction. NP1 nickel mesh is the highest-performing non-platinum candidate currently validated.
Validation & Case Study
At the Indian Institute of Science, Bangalore, electrochemistry and nanotechnology researchers conducted Oxygen Evolution Reaction (OER) testing on bare NP1 nickel mesh and NP1 mesh coated with ruthenium oxide (RuO₂). Operating at 1 A/cm² current density with 24-hour stability profiling, the RuO₂-coated mesh achieved 94.3% Faradaic efficiency and 99.2% current stability. 1,000-hour durability was confirmed in continuous operation; projected operational lifespan exceeds 50,000 hours.
The 5–10% efficiency gain versus platinum systems, combined with a ~95% reduction in catalyst material cost, fundamentally restructures the unit economics of green hydrogen production at scale.
Supply Chain Significance
The EU Green Deal requires 100 GW of electrolyser capacity by 2030. Each gigawatt of electrolyser installed represents material demand measured in hundreds of kilometres of high-purity nickel mesh. Against a Class 1 nickel deficit of 710,000 tonnes by 2029 and European concentration of NP1 wire-drawing capacity, the hydrogen sector alone could absorb multiple years of global NP1 wire output without satisfying its mandated capacity build.
Frequently Asked
It replaces or substantially reduces platinum-group metal loading in alkaline and anion-exchange-membrane (AEM) electrolyser designs. Proton-exchange-membrane (PEM) electrolysers continue to require some platinum-family catalysts, though ruthenium-coated nickel mesh is an active research substitute for iridium in PEM anodes.
Ruthenium oxide significantly improves OER kinetics at the anode — lifting Faradaic efficiency from 89.7% (bare nickel) to 94.3% (coated), exceeding platinum-system performance. The ruthenium loading required is a small fraction of the platinum loading it replaces.
1,000 hours of direct continuous-operation testing were performed at IISc Bangalore. The 50,000-hour projected lifespan is derived from electrochemical accelerated-ageing extrapolation using standard electrolyser-industry models, not direct measurement.
