Tohoku University scientists Pioneer Affordable Hydrogen Fuel Production
April 28, 2025
The Quest for Clean Energy Just Got a Boost
scientists at Tohoku University’s Advanced Institute for materials Research (AIMR) have unveiled a groundbreaking method for producing affordable hydrogen fuel. Their innovative surface reconstruction strategy for catalysts promises to make clean hydrogen fuel commercially viable.
Did You Know?
Hydrogen fuel cell vehicles emit only water vapor, offering a true zero-emission choice to customary combustion engines [[2]].
The research, published in Advanced Energy Materials on April 3, 2025, details how the team’s approach could meet the U.S. Department of Energyโs (DOE) ambitious 2026 hydrogen production cost target.
Tackling Inefficiencies wiht Non-Noble metals
The hydrogen evolution reaction (HER) is critical for generating clean hydrogen fuel, a key component in addressing the climate crisis [[3]]. However, HER’s inherent inefficiencies and slow reaction speeds have hampered its widespread adoption.
Traditionally, expensive noble metals are used as catalysts to accelerate this reaction.The Tohoku University team sought more affordable alternatives, focusing on transition metal phosphides (TMPs), durable and cost-effective non-noble metal compounds with catalytic potential.
Fluorine: The Key to Enhanced Catalytic Activity
The team’s novel strategy involves modifying cobalt phosphide (CoP) with fluorine. Through experimentation and advanced analytical techniques, including operando X-ray absorption spectroscopy (XAS) and Raman measurements, they uncovered the mechanism behind the enhanced catalytic performance.
Incorporating fluorine into the CoP lattice creates phosphorus vacancy sites on the catalyst’s surface. These vacancies act as highly active sites, substantially accelerating the HER process.
Pro Tip
emerging clean hydrogen economies could reshape global energy and political relations, perhaps creating a new balance of power [[1]].
Performance and Cost Projections
The modified catalyst, F-modified CoP, demonstrated extraordinary durability, maintaining stable performance for over 300 hours under acidic conditions. This is a crucial requirement for proton exchange membrane (PEM) electrolyzers.
Heng Liu, led researcher at AIMR, emphasized the economic viability of their approach:
This reconstructed Co is highly active, works in acidic conditions, and can maintain approximately 76 W for over 300 hours. Weโre getting close to an affordable method to produce fuel. The calculated cost of using this method is $2.17 per kgH2-1 โ just 17 cents over the current production target set for 2026.

From Lab to Commercial Submission
Beyond laboratory experiments, the researchers extended their findings to commercial-scale PEM electrolyzers, demonstrating the practical potential of their innovation. This advancement represents a meaningful step forward in HER catalyst research, providing a blueprint for designing other high-performance non-noble metal-based cathodes.
A Sustainable Energy future
Liu emphasized the importance of translating research into real-world applications:
Weโre always thinking about the end goal, wich is for research to make its way into everyday life.This advancement brings us one step closer to designing more realistic options for commercial PEM application.
