    Good environmental governance for renewable energies: The example of Germany - lessons for China?

    No full text
    Germany’s pioneering role in the field of renewable energies (RES) can best be observed by its world leading position in installed wind power and photovoltaics. Also its first European rank in the production of biofuels and installed solar thermal collector space is remarkable. These successes are not due to an exceptionally good natural resource base; mainly they are the result of an innovative national support policy. Pressure from the European and international commitments also have contributed to the German success story in RES. The current paper analyses the main factors of the German case in the development of RES, including the design elements of the national promotion instruments and support programmes, the policy impacts from the European and the international level, technical as well as cognitive conditions. In addition, a description is given of further driving forces for a successful RES development in other European countries. The paper ends with the question which of the described success factors of the German RES case might be transferable to China - and which not. --

    Biocatalyst Selection for a Glycerol-oxidizing Microbial Fuel Cell

    No full text
    Using glycerol from biodiesel production as a fuel in a microbial fuel cell (MFC) will generate electricity and valuable by-products from what is currently considered waste. This research aims to screen E. coli (W3110, TG1, DH5, BL21), P. freudenreichii (subspecies freudenreichii and shermanii), and mixed cultures enriched from compost (AR1, AR2, AR3) as anodic biocatalysts in a glycerol-oxidizing MFC. Anaerobic fermentation experiments were performed to determine the oxidative capacity of each catalyst towards glycerol. Using an optimized medium for each strain, the highest anaerobic glycerol conversion from each group was achieved by E. coli W3110 (4.1 g/L), P. freudenreichii ssp. shermanii (10 g/L), and AR2 (20 g/L). These cultures were then tested in an MFC system. All three catalysts exhibited exoelectrogenicity. The highest power density was achieved using P. freudenreichii ssp. shermanii (14.9 mW m-2), followed by AR2 (11.7 mW m-2), and finally E. coli W3110 (9.8 mW m-2)
