First Graphene Limited has released the findings of an independent study conducted by the Centre for Process Innovation UK (CPI), highlighting the potential of graphene-based electrocatalysts for green hydrogen production.

The study revealed that electrodes containing metal-oxide doped graphene from First Graphene reduced the power required for water electrolysis in hydrogen generation.

Analysis by CPI indicated a remarkable 43 per cent reduction in overpotential, signifying increased energy efficiency, the ASX-listed company reported in a media release.

The study also identified process improvements leading to a 64 per cent increase in throughput, a 50 per cent reduction in raw material costs, and expanded metal oxide options, presenting a cost-effective solution for the green hydrogen industry.

The research showcased the effectiveness of First Graphene’s metal-oxide supercapacitor materials in reducing power consumption, providing a sustainable alternative to electrocatalysts that often rely on rare and expensive metals.

The patented technology, exclusively licensed to First Graphene from the University of Manchester, holds significant promise for advancing green hydrogen production methods.

The project received funding from the Net-Zero Tees Valley program, supporting the development of manufacturing expertise for electrode materials.

As the global demand for green hydrogen continues to rise, advancements in electrolysis processes using renewable electricity are crucial, and First Graphene’s innovative approach positions it at the forefront of this sustainable energy revolution.

The International Energy Agency projects a substantial increase in hydrogen electrolysis, reaching between 170 and 365 GW by 2030, underlining the strategic importance of graphene-based technologies in contributing to a greener future.

The water electrolysers market is anticipated to surpass USD 7 billion by 2031, with electrocatalyst materials expected to reach USD 1.2 billion by 20304, highlighting the significant commercial potential of First Graphene’s groundbreaking advancements.

First Graphene’s Managing Director and CEO Michael Bell expressed enthusiasm about the recent breakthrough, stating that it marks an exciting development for the company.

“This is an exciting development for First Graphene as we develop our next generation of products that can be used in high value industries that will be part of the solution for decarbonisation,” Bell noted.

He added, “With rapid growth expected in hydrogen production catalysts, these results place First Graphene in a strong position to provide a high-performing, cost-effective, graphene-enhanced solution.”
