Researchers at Linköping University in Sweden have developed a new material capable of efficiently harnessing solar energy needed to break down water in order to extract hydrogen. This material, nanoporous cubic silicon carbide, could thus increase the production of hydrogen gas using renewable sources and without carbon dioxide emissions.
There are many ways to produce hydrogen, from different sources. Most of the production today comes from the transformation of fossil fuels, especially natural gas, because it is the cheapest solution. Hydrogen can also be obtained by decomposing water, by electrolysis – electricity being provided by nuclear, wind or solar power. But this technique is still not very widespread, because it is much more expensive. The use of a more efficient material could therefore be a game-changer …
