Water and sunlight could be used to produce hydrogen as a cheap and clean source of fuel.
Australian National University researchers modified a protein so that it replicated a crucial step in photosynthesis to produce energy when exposed to sunlight.
The findings, which were published in journal BBA Bioenergetics, could pave the way for the creation of a highly efficient, sustainable and affordable fuel, which would be a zero-carbon replacement for petroleum.
