Biomass production by micro algae is by a factor of 10 more efficient then plants. This gives the chance to create an economic process of solar energy harvesting. In view of the very low dry mass content of algal suspensions the most promising way of conversion to a high exoergic and transportable form of energy is the anearobic production of biogas.
We are actually developing such processes especially micro algal reactors, a method to separate micro algal cells, a method to treat the micro algal biomass and a two stage anaerobic process. First results of these project sections are shown. The developed anaerobic process is very efficient but also very unstable. To get a better process management it is necessary to understand the influences between the parameters of process engineering and biochemical parameters like the concentration of carboxylic acids. Goal of this part of the project is the development of an inline sensor. The project was funded by the German Federal Ministry for Education and Research (BMBF).
