Researchers at the University of Birmingham have developed a perovskite catalyst that splits water into hydrogen and oxygen at significantly lower temperatures than traditional methods. This breakthrough allows industrial waste heat from steel, cement, and glass plants to be used for local hydrogen production, reducing the need for expensive transport and storage infrastructure. Preliminary analysis suggests this thermochemical approach could be more cost-effective than current green or blue hydrogen pathways, particularly in regions with low renewable energy costs. The use of barium, niobium, calcium, and iron makes the catalyst materials accessible and non-toxic.
