The cultivation of microalgae for the production of high quality products for the dietary supplement industry is associated with large effort. Biomass production in open pond reactors can lead to contamination with other algae or pollutants and can cause a reduction of the product quality. In closed reactors, such as tubular reactors, the natural lighting conditions and their consistency play an important role. Fluctuations in light supply can lead to varying product qualities. Nevertheless, closed processes powered by artificial light are very energy intensive and therefore very expensive. These methods are only economical to operate with persistently high commodity prices. During indoor cultivation, the high cost of artificial lighting are assiciated with high cost for cooling of the reactor systems. In the present work, the power saving potential of a given industrial plant in several layouts are derived theoretically at first. Furthermore, these values are compared with a specified basic plant version in terms of energy saving, cost saving and the space required by theoretical loading calculations and comparison with an existing DEMO-plant.
