London, Monday, 3 November 2025.
A new electrocatalyst, the NiMoCu electrode, has achieved a 70% energy efficiency in grey hydrogen production. This development is crucial as hydrogen demand soars to 97 million tons, pushing for sustainable solutions.

A Catalyst for Change

The recent innovation in electrocatalysts, specifically the development of sputtered ternary NiMoCu electrodes, has set a new benchmark for energy efficiency in grey hydrogen production, achieving an impressive 70% efficiency [1]. This is a significant leap forward, considering the conventional production methods are far less efficient [2]. With the global demand for hydrogen soaring to 97 million tons, this technological advancement couldn’t have come at a more crucial time [3].

The Urgent Need for Sustainability

As the demand for hydrogen escalates, the focus has shifted towards making its production more sustainable. Grey hydrogen, which is currently the most prevalent form, is produced through steam methane reforming, a process notorious for its high CO2 emissions [4]. The NiMoCu electrode’s enhanced efficiency provides a beacon of hope for reducing these emissions, aligning with global efforts to transition towards more environmentally friendly practices [5].

Competitive Edge in the Hydrogen Race

Despite the dominance of grey hydrogen due to its low production cost, the push for greener alternatives is intensifying. While green hydrogen remains costly, ranging from USD 3.50 to USD 5.50 per kilogram, innovations like the NiMoCu electrode are paving the way for cost-effective solutions that could bridge the gap between grey and green hydrogen [6]. This development supports global initiatives such as the U.S. Department of Energy’s Hydrogen Shot Initiative, which aims to slash green hydrogen costs to USD 1 per kilogram by 2031 [7].

A Step Towards a Greener Future

The introduction of these new electrocatalysts is not just about improving efficiency; it’s about setting a precedent for future innovations in hydrogen technology. As we continue to explore and develop methods like carbon capture and storage in conjunction with traditional hydrogen production techniques, the ultimate goal remains clear: achieving a sustainable hydrogen economy. With countries worldwide setting ambitious targets for carbon neutrality, advancements like these are critical in ensuring we meet those goals [8].
