Researchers have made significant efficiency improvements to the technology used to generate solar fuels. This involves the direct conversion of energy from sunlight into a usable fuel (in this case, hydrogen).

The trick was to decouple the site where sunlight is captured from the site where the conversion reaction takes place.https://www.sciencedaily.com/releases/2018/01/180115121641.htm
