Bioenergy

Examples of fuels produced from biomass are biomethane, renewable natural gas (RNG), biogenic hydrogen, biokerosene, biomethanol, bioethanol and higher alcohols. However, in future, care must be taken to avoid the well-documented conflict between crops used for food and those used for fuel production. The bioeconomy strategy therefore calls for only using the biomass that cannot be used for producing food. Microalgae, biowaste and residual materials have huge potential in this area.

    Whole-genome sequence analyses have become indispensable for algal research. Sequence analyses provide information on the evolution of different groups of algae and contribute to our understanding of the molecular mechanisms algae use to adapt to climate change as well as unlocking the potential to develop new and economically important products and technologies.

    What can we do with all the waste produced by private households? One possible solution is to feed it into a fridge-sized tank in the cellar or garage that can convert waste into electricity. Dr. Sven Kerzenmacher and Dr. Johannes Gescher from the University of Freiburg are hoping that one day such a vision will be made possible through the use of bacteria. The two researchers work with so-called exoelectrogenic microorganisms which they put into…

    Chemical energy is stored in the material used for packaging carpets and so on. Some of this energy can be recycled from discarded products. Every year the Thermische Restabfallbehandlungs- und Energieerzeugungsanlage TREA Breisgau Thermal Residual Waste Treatment and Energy Generation Facility located in the Breisgau industrial estate close to Freiburg converts around 170000 t of residual waste into electricity. Dr. Holger Heinig COO of TREA…

    Conventional biogas plants have the disadvantage that the production of energy cannot be controlled in a flexible way. Therefore, Großmann Ingenieur Consult GmbH (GICON) has developed a fast, simple method for controlling biogas production from renewable resources. In addition, the two-stage dry-wet fermentation process with split hydrolysis makes it possible to control the two stages independently. Heribert Krämer, head of the GICON subsidiary…

    Ozan Gökay, chemical engineer and chemist, has been thinking about setting up his own company for many years. Now he is about to turn his plans into reality and his company ANASYN will start operating in November 2010. The company will focus on analytics, syntheses and biotechnology.

    It is rather reassuring to know that fossil energy carriers can be replaced by renewable ones. However, the difficulties are always in the details. For example with regard to the storage capacity of electricity produced with sun and wind; or with regard to the use of biomass to produce natural gas substitutes. The Stuttgart-based Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) has a number of solutions up its sleeve for…

    Partners from industry and research have joined forces to develop an innovative method for the production of biogas. In contrast to standard methods, the chemical degradation processes will in future take place in different tanks rather than in just one. The developers hope that the separation of the processes will expedite the degradation processes, improve the quality of the individual degradation products, and enable their broad applications.…

    The potential of Microalgae cannot yet be optimally used on the large scale. The bioprocess engineer Dr. Rosa Rosello and her team at the Karlsruhe Institute of Technology KIT are investigating the conditions under which different microalgae species can optimally grow in photobioreactors and lead to high product yields. It is all a question of light and shade.
