Scientists have harnessed the principles of photosynthesis to develop a new way of producing hydrogen – in a breakthrough that offers a possible solution to global energy problems.
The researchers claim the development could help unlock the potential of hydrogen as a clean, cheap and reliable power source.
Unlike fossil fuels, hydrogen can be burned to produce energy without producing emissions. It is also the most abundant element on the planet.
Hydrogen gas is produced by splitting water into its constituent elements – hydrogen and oxygen. But scientists have been struggling for decades to find a way of extracting these elements at different times, which would make the process more energy-efficient and reduce the risk of dangerous explosions.
In a paper published today in the journal Nature Chemistry, scientists at the University of Glasgow outline how they have managed to replicate the way plants use the sun’s energy to split water molecules into hydrogen and oxygen at separate times and at separate physical locations.
