Japan has found the holy grail of electrolysis: a cheap metal that can produce 1,000% more hydrogen.
Green hydrogen, produced from renewable energy sources by electrolysis of water, is the great promise of the energy sector. Countries like Spain are banking on this energy carrier for their future, but further research is needed to ensure that it can be produced on a sustainable scale. And on this…
In recent years, PEM electrolysers, which use a proton exchange membrane as the electrolyte, have become increasingly popular for hydrogen production because of their greater efficiency and their ability to respond rapidly to intermittent energy sources. Researchers have developed a manganese oxide (MnO2) catalyst by manipulating the lattice structure of the material so that it forms stronger bonds with oxygen atoms. Future modifications to the manganese structure could further increase the current density supported by the material and the lifetime of the catalyst, with the long-term aim of making water electrolysis iridium-free.
