Microalgae (the family Chlamydomonas) to improve the operation of biogas plants Source BE ADIT

The working group led by Prof. Dr. Gerd Klöck and Dr. Anja Noke, biotechnologists from the Institute of Environmental and Biological Techniques at the Bremen University of Applied Sciences, are focusing their work on developing new processes for the industrial use of microalgae. In this context, since the 1er July 2008, he has been carrying out a project on the improvement of biogas plants, entitled AlgenBiogas. The Federal Ministry of Education and Research (BMBF) supports it for a duration of 3 years, up to 245.000 euros within the program "FHprofUnd" (research in specialized colleges in collaboration with companies).

The biogas produced in the reactor contains, in addition of the desired fuel, methane, other gases such as CO2 and hydrogen sulfide (H2S). If these gases are present in too high concentrations and that the proportion of methane falls below a certain threshold, then the biogas is no longer usable for combustion.

The objective of AlgenBiogas is the development of a method of removing the H2S and CO2 in biogas using microalgae. These can indeed use the gas to increase their own biomass. The oxygen produced during photosynthesis this can then be removed by a suitable method. The formed microalgal biomass is then used as a substrate for biogas formation process. Previously, materials useful as 3 Omega and Omega 6 or carotenoids can be extracted from seaweed.

A suitable pilot plant is to be built and tested for several months in connection with a biogas plant, in collaboration with Algatec companies (Bremen) and MT-Energie (Lower Saxony). The research and development should lead to the design of a commercial facility, which will complement the new biogas units or already in operation.

A parallel sub-project, which begins at the University of Applied Sciences Anhalt will, among others, to choose and cultivate adapted and retrieve products from the algal biomass microalgae. The partners of the School of Anhalt in this project are the BiLaMal group, and Stollberg and LUM GmbH.
