New carbon-free hydrogen fuel production method slashes temperature requirement by 900°F

University of Birmingham researchers developed a barium-niobium-calcium-iron perovskite catalyst that can produce hydrogen from water at 150-500°C, far below the usual 1300-1500°C range.

The catalyst stayed stable over repeated thermochemical water-splitting cycles and showed strong performance in tests published in the International Journal of Hydrogen Energy.

A techno-economic analysis suggests the approach could be cost-competitive with today’s blue and green hydrogen pathways.

The lower operating temperature could make hydrogen production easier to site near renewable energy or industrial waste-heat sources, reducing transport and fossil-fuel dependence.
