University of Birmingham Develops Low-Temperature Perovskite Catalyst for Hydrogen Production

en.Wedoany.com Reported - The University of Birmingham, in collaboration with the University of Science and Technology Beijing, has developed a perovskite catalyst capable of splitting water for hydrogen production at low temperatures. The related findings were published in the International Journal of Hydrogen Energy. This catalyst reduces the thermochemical water splitting temperature to 150-500 degrees Celsius, with the regeneration temperature also lowered to 700-1000 degrees Celsius, significantly below the temperatures required by traditional catalysts.

The research team, led by Professor Yulong Ding, used a BNCF perovskite made from barium, niobium, calcium, and iron, which is readily available and non-toxic. The catalyst remained stable over 10 production cycles, with X-ray diffraction showing no significant changes in its structure. Professor Ding said, "The overall process temperature is low, allowing hydrogen production to be sited near renewable energy power plants. Furthermore, foundation industrial sectors such as steel, cement, glass, and chemicals have large amounts of waste heat, which can serve as thermal input for low-temperature hydrogen production."

Preliminary cost analysis shows that this low-temperature hydrogen production method is cheaper than green hydrogen produced via electrolysis and blue hydrogen from methane reforming combined with carbon capture, with significant advantages especially in regions with low renewable energy electricity prices, such as Australia. The University of Birmingham has filed a patent application and is seeking partners to advance commercialization. This technology offers a new pathway for localized hydrogen production using industrial waste heat, helping to overcome barriers in hydrogen storage and transportation.
