SPAIN – Researchers at the UAB’s Institute of Environmental Science and Technology (ICTA-UAB) and the Institute of Marine Sciences (ICM-CSIC), have analysed the potential of different species of microalgae for producing biodiesel, comparing their growth, production of biomass and the quantity of lipids per cell (essential for obtaining fuel).

Their study shows that one type of marine algae that has received little attention till now – dinoflagellate microalgae – is highly suitable for cultivation with the aim of producing biodiesel.

The scientists carried out the whole production process in exterior cultures, in natural conditions, without artificial light or temperature control, in cultivation conditions with low energy costs and subject to seasonal fluctuations.

Detailed analysis of all costs over four years gives promising results: microalgae cultures are close to producing biodiesel profitably even in uncontrolled environmental conditions.
