Researchers at the University of Birmingham have developed a lower-temperature method for hydrogen production that could significantly reshape how clean fuel is generated. Led by Yulong Ding, the team demonstrated a new approach to water splitting using a perovskite catalyst, cutting operating temperatures by as much as 500°C. The study shows that hydrogen can now be produced at temperatures between 150°C and 500°C, far below those of conventional thermochemical processes. The result is a more energy-efficient system that can integrate with industrial waste heat, opening the door to decentralised hydrogen production. Published in the International Journal of Hydrogen Energy, the research suggests this method could also lower production costs compared to existing green and blue hydrogen pathways, particularly in regions with lower renewable energy costs. A shift in how hydrogen is made Hydrogen is widely seen as a cornerstone of the low-carbon transition. It produces only water when used as a fuel and can power fuel cells or be burned for heat. Yet the reality is less clean: around 95% of global hydrogen production still …
