Researchers at the University of Birmingham have developed a new catalyst-based process that could significantly lower the cost and energy requirements of hydrogen production, potentially making it cheaper than current green and blue hydrogen methods.

Hydrogen is widely seen as a key low-carbon fuel for industries such as transport and heavy manufacturing, but most global supply still comes from fossil-fuel-based processes that emit carbon dioxide. Cleaner alternatives like electrolysis exist, but they remain expensive and energy-intensive at scale.

The Birmingham team has advanced a thermochemical water-splitting approach that uses a perovskite catalyst to produce hydrogen at much lower temperatures than conventional systems. While standard thermochemical methods typically require 700–1000°C for operation and even higher temperatures for regeneration, the new method reduces operating temperatures to roughly 150–500°C and regeneration requirements to 700–1000°C.

This reduction of up to 500°C could allow the process to use industrial waste heat from sectors such as steel, cement, glass, and chemicals, enabling more localized hydrogen production near existing infrastructure or renewable energy sites.

Cost analysis included in the study indicates the method could outperform both electrolysis-based green hydrogen and methane-based blue hydrogen with carbon capture, depending on local energy prices.

The catalyst, a barium–niobium–calcium–iron (BNCF) perovskite material, showed stable performance over multiple cycles with minimal structural degradation. The research, conducted with the University of Science and Technology Beijing, has already led to patent filings and early-stage commercial exploration in the UK and Europe.

Published in the International Journal of Hydrogen Energy, the findings suggest a potential pathway toward lower-cost hydrogen production with reduced reliance on high-temperature industrial processes.
