In order to use microalgae as a fuel the algae should be of high calorific value and must be capable of growth in large volumes. Chlorella vulgaris and C. emersonii have been shown to grow in a 230 1 pumped tubular photobioreactor in Watanabe's medium and a low nitrogen medium. The low nitrogen medium induces higher lipid accumulation in both algae, which increased their calorific value. The highest calorific value was obtained with C. vulgaris (28 kJ g-1) grown in low nitrogen medium. However, the biomass productivity was 24 mg dry wt l-1 d-1 in the low nitrogen medium which was lower than in Watanabe's medium (40 mg dry wt l-1 d-1) and represents a reduced energy recovery. © 2002 Elsevier Science Ltd.

Microalgae can be either used directly as a fuel or to produce oil for biodiesel. In both cases the microalgae should have a high calorific value and be grown in large volumes.|
