Algae Could Be Major Hydrogen Fuel Source
While the first algae-to-biofuels facility went online today, scientists at Argonne National Labs are manipulating the photosynthetic super-organism for another use: creating hydrogen.
Algae grows prolifically in adverse conditions, and can store large amounts of oils or starches useful for making biodiesel or ethanol. But some strains also use an enzyme called hydrogenase to produce small amounts of hydrogen gas. Scientists think this is the organism’s way of getting rid of excess energy under high-light conditions.
