Scientists at the University of Birmingham have developed a new way to produce hydrogen that's cheaper and more practical. This clean fuel can power cars and homes without harming the environment.

Hydrogen is an important clean energy source. When used as a fuel, it produces only water and heat instead of carbon dioxide and other pollutants. However, most hydrogen production today still depends on fossil fuels. A team led by Professor Yulong Ding from the University of Birmingham's School of Chemical Engineering has made a breakthrough in producing hydrogen at a lower cost.

The researchers developed a new low-temperature approach to hydrogen production that can be used in both large centralized facilities and smaller local systems. This technique uses waste heat from major industrial operations, making it more practical and efficient.

In the past, thermochemical water splitting required extremely high temperatures. The new catalyst, perovskite, significantly reduces these temperatures, making it possible to generate hydrogen at temperatures between 150-500°C. This could enable hydrogen production near renewable energy generation plants and industrial sectors that have abundant waste heat.

The researchers also conducted a preliminary economic analysis and found that their method could produce hydrogen at a lower cost than both green hydrogen (produced from water by electrolysis) and blue hydrogen (produced from methane with carbon capture and storage). This is especially true in areas where renewable electricity is relatively inexpensive, such as Australia.

The project was carried out in collaboration with the University of Science and Technology Beijing (USTB). The University of Birmingham is now working to commercialize the technology in the UK and Europe.
