The Technical University of Munich (TUM) has built a worldwide one-of-a-kind technical facility for algae cultivation at the Ludwig Bölkow Campus in Ottobrunn to the south of Munich, in cooperation with Airbus Group. Efficient processes for producing biokerosene and chemical products from algae will be developed there. The AlgaeTec facility was recently inaugurated in the presence of the Bavarian Minister of Education, Cultural Affairs, Science and the Arts, Dr. Ludwig Spaenle, Airbus Group’s Chief Technical Officer, Dr. Jean Botti, and TUM president, Professor Wolfgang A. Herrmann.
Scientists estimate that there are some 150 000 different types of algae. Around 5 000 of them have been fundamentally characterised, yet only around ten species have been implemented for commercial exploitation. With their new algae facility, researchers aim to change this. They hope to develop efficient processes for the production of biokerosene and chemical products there.
The 1 500 m² building houses three areas for algae cultivation, as well as laboratory and office space. What sets the Ottobrunn algae centre apart is the fact that lighting and climate conditions for practically any location on Earth can be simulated.
The building’s façade comprises special highly transparent glass that also lets ultraviolet light pass through it. Elaborate climate technology ensures that both tropical and very dry climate conditions can be created. Two different climate zones can be simulated in the two outer halls. The middle hall is geared to cultivation and preparatory experiments.
Additional LED lighting allows the simulation of light and climate conditions of practically any location on Earth. These highly efficient LEDs provide light in the 300 to 800 nanometer wavelength range and an intensity distribution that closely mimics that of sunlight. Since the different LED types can be individually controlled and adjusted, researchers can also configure specific spectra that differ from that of the sun.
“No one can predict whether or not a specific alga from the South Pacific will be just as productive in Germany as it is in its native environment,” says Thomas Brück. “In the same vein, no one knows whether species which are successful in Bavaria would function as well in the light conditions of the Sahara, but now we can test all of this in our technical facilities.”
Cultivation is not limited to just one type of photo-bioreactor. Various open and closed systems can operate in parallel in the halls, under the same or different climate conditions. Thanks to the facility’s elaborate building automation systems, the algae centre’s operations are highly energy efficient.
“While the production of biofuels from corn implies a problematic competition between nutritional use and fuel,” says Professor Thomas Brück, Professor for Industrial Biocatalysis at the Technical University of Munich, “algae also grow in saltwater and require neither arable land nor pesticides. Still, they can generate up to ten times higher yields per hectare and year.”
The AlgaeTec facility is a key part of the “AlgenFlugKraft” (Algae Aircraft Fuel) project, which is funded by the Bavarian State Ministry of Economic Affairs and Media, Energy and Technology. Further project partners include the Department of Technical Chemistry II (catalytic conversion of biomass) and the Institute of Biochemical Engineering (technical scaling of cultivation) at TUM; Airbus Group, Clariant Produkte Deutschland GmbH (algae processing, oil separation) and conys GmbH (hydrogen / biogas production).
