Scientists from the University of Cambridge, the United Kingdom, have developed an innovative new method of producing hydrogen fuel. The method involves combining ambient sunlight and biomass, such as paper, wood, and leaves, in order to generate hydrogen. Converting biomass into hydrogen has long been an interest for the renewable energy community, but relatively few endeavors have managed to find success. The new method mainly focuses on biomass waste.

The new system leverages a photocatalyst in an alkaline water solution. The photocatalyst is comprised of various nanoparticles. When exposed to sunlight, either natural or synthetic, the photocatalyst triggers any biomass particles present in its alkaline solution to produce gaseous hydrogen. Notably, the hydrogen pro-duced using this method is free from fuel cell inhibitors, such as carbon monoxide.

This means that the hydrogen can be used by a fuel cell to generate electricity in an efficient and sustainable manner. The research team intends to bring their new hydrogen fuel production system to the commercial market at some point in the future. The research team predicts that the new system could be effective for small-scale hydrogen fuel production, but it could be scaled up for industrial use in the future.
