Biogas-conditioning with microalgae

Year: 2009

Type: article

Abstract: To promote the expansion of feasible biogas production, an optimisation of the whole process chain is essential. In this context the optimisation of the biogas-conditioning process is of great importance. By improving this process, new fields of application, e.g. its usage as car fuel or natural gas substitute can be developed. Currently applied chemical/physical conditioning techniques are cost intensive and hinder a reasonable production for smaller biogas plants. At present a possible low-cost alternative by application of microalgae is being investigated at the University of Rostock. To determine their ability to reduce carbon dioxide from biogas, laboratory-scale photobioreactors with a culture volume of 0.45 l are deployed. In 2008 the microalgae Chlorella sp. was analysed in terms of conditioning biogas. As a result the biogas components CO2 and H2S could be reduced up to 97.07% and 100%, respectively. Also an increase of microalgae cell count could be documented, which provides interesting alternatives for the production of algae ingredients.
