Artificial Photosynthesis: A New Renewable Energy Source?
An international team of scientists has made a major breakthrough for the future of sustainable fuel. They achieved this major milestone by copying the methods of some of the cleanest energy producers on the planet—plants. Scientists from the University of Cambridge and the Ruhr University Bochum have discovered a new technique that mimics the natural process of photosynthesis in plants, which could be used to produce hydrogen fuel, an extremely clean (zero carbon dioxide emissions) and essentially unlimited energy source.
In a paper published in the Nature Energy scientific journal, the team of scientists explained their proof-of-principle method for splitting water molecules into the individual hydrogen and oxygen atoms of which they are composed using sunlight. The technique mirrors photosynthesis, the natural process wherein plants split water molecules when they convert sunlight to energy to feed themselves. This achievement has far-reaching implications—Erwin Reisner, lead author of the study, told Newsweek that “solar energy conversion to produce renewable fuels and chemicals—i.e., solar fuel synthesis—is an important strategy for powering our society in a post-fossil era.”
