en.Wedoany.com Reported - Researchers at the University of Birmingham have developed a method for producing hydrogen at lower temperatures using a perovskite catalyst. The research team stated that thermochemical water splitting can be carried out within a temperature range of 150°C to 500°C, a reduction of approximately 500°C compared to the 1300°C to 1500°C required by conventional methods.

The catalyst, named BNCF100, is composed of barium, niobium, calcium, and iron—materials that are readily available and non-toxic. It remained stable over ten production cycles, with X-ray diffraction showing minimal structural changes. Professor Yulong Ding, who led the research, noted that the lower temperatures allow the hydrogen production process to utilise heat from renewable energy power plants or industrial waste heat, with significant waste heat from industries such as steel and cement serving as thermal input.

Cost analysis indicates that this method is cheaper than producing blue hydrogen from methane or green hydrogen via electrolysis, particularly in regions with low electricity prices such as Australia. This research was completed through collaboration between the University of Birmingham and the University of Science and Technology Beijing. The University of Birmingham has applied for a patent for the use of the BNCF catalyst in low-temperature water splitting and is seeking partners to promote it in the UK and Europe. Professor Ding concluded: "Our research has identified a catalyst that produces significant amounts of hydrogen at relatively low temperatures, and preliminary techno-economic studies show its cost is competitive."
