Reducing carbon emissions in order to prevent climate change requires developing new technologies for sustainable and renewable biofuel production. Molecular hydrogen is regarded as one of the most promising energy carriers due to its high energy density and clean, carbon-free use. A research group from the University of Turku, Finland, has discovered an efficient way for transforming solar energy into the chemical energy of biohydrogen through the photosynthesis of green algae that function as cell factories.
During photosynthesis, green algae utilise harvested solar energy to split water, release oxygen into the atmosphere and produce biomass that functions as an excellent feed-stock in the blue biorefinery.
