What is it about?
Molecular hydrogen is an ideal energy carrier for a sustainable and low-carbon economy. The green algae are capable of producing hydrogen by splitting water with energy from sunlight. Hydrogen production in green algae is difficult to sustain due to extreme sensitivity of this process to oxygen, which is simultaneously released by photosynthetic apparatus of algal cells in the light. This article examines a breakthrough protocol for sustaining efficient hydrogen photoproduction in algae by transferring the growing cultures from continuous light to a train of strong light pulses superimposed on darkness or low background illumination.

Why is it important?
The novel protocol shows a way for the renewable production of hydrogen biofuel using green algae as photosynthetic cell factories.
