Teaching algae to make fuel

Many kinds of algae and cyanobacteria, common water-dwelling microorganisms, are capable of using energy from sunlight to split water molecules and release hydrogen. One reason this approach hasn’t yet been harnessed for fuel production is that under ordinary circumstances, hydrogen production takes a back seat to the production of compounds that the organisms use to support their own growth. Scientists have found a way to use bioengineered proteins to flip this preference, allowing more hydrogen to be produced.
