A Breakthrough That May Reshape Hydrogen Economics

A copper-based catalyst could cut costs and ease supply risks for green hydrogen at scale

13 Feb 2026

Green hydrogen has long promised a cleaner energy system, but high costs have slowed its expansion. Researchers now say a catalyst made from copper, nickel and iron could reduce reliance on scarce precious metals and lower barriers to industrial production.

The material is designed for use in alkaline electrolyzers, the machines that split water into hydrogen and oxygen. Most high-performance systems depend on iridium and ruthenium, metals that are rare, expensive and concentrated in limited supply chains.

Supply concerns have sharpened as Europe and other regions accelerate hydrogen strategies. Governments are backing the fuel to decarbonise heavy industry, but rising demand for electrolyzers has increased pressure on critical materials. Limited availability risks pushing up costs and delaying projects.

The new catalyst replaces precious metals with more abundant base metals. According to early laboratory results, it can operate under the high power loads required for industrial-scale hydrogen production. If confirmed, that performance could help stabilise input costs and reduce exposure to supply bottlenecks.

Researchers also point to a simpler production method. The catalyst can be synthesised in a single step at room temperature, potentially lowering manufacturing complexity and reducing capital requirements for producers. Conventional processes for precious metal catalysts are often more energy intensive and costly.

Environmental considerations may further strengthen its appeal. A lifecycle analysis associated with the research estimates the material could cut environmental impacts by 40 to 60 per cent compared with precious metal alternatives. That reduction could support developers facing stricter sustainability standards, particularly in the European Union.

However, the technology remains at an early stage. While the catalyst has performed well in laboratory tests and extended bench trials, long-term durability under continuous industrial use has yet to be demonstrated. Commercial electrolyzers must operate reliably for years, not hundreds of hours.

Large-scale trials will determine whether the material can meet those demands. As hydrogen projects move from pilot phase to heavy industry, the outcome may influence how quickly the sector can expand while containing both costs and supply risks.
