Immissionsbelastungen im Umfeld des Flughafens München.

show abstract

Die Immissionsbelastung im östlichen Umland des neuen Münchner Flughafens wurde im Zeitraum von 1992 bis 1995 mit Hilfe einer Reihe unterschiedlicher Messmethoden untersucht. Für die wirkungsbezogene Erfassung von Umwelteinflüssen wurden Bioindikatoren zur Bestimmung der PAK-Belastung und zur Quantifizierung der Photooxidantienbelastung eingesetzt. Darüber hinaus wurde der PAK-Gehalt des Oberbodens bestimmt. Die aktuelle Luftbelastungssituation wurde während photochemisch aktiver Wetterlagen im Sommer im Rahmen von 7 Intensivmesskampagnen untersucht. Die Bodenbelastung mit PAK liegt im Bereich der für ländliche Regionen typischen Hintergrundwerte mit den höchsten Konzentrationen in der Nähe stark befahrener Straßen und weist keinen zeitlichen Trend auf. Auch der aktuelle PAK-Eintrag liegt an allen Standorten in einem für ländliche Regionen in Bayern typischen Bereich. Als Hauptemittent wird im Sommer der Kfz-Verkehr identifiziert, während die deutlich erhöhte Belastung im Winter auf den Hausbrand zurückgeführt werden kann. Die Photooxidantien-belastung zeigt im Flughafenumland keine ausgeprägten Unterschiede, sie ist an den durch Straßenverkehr beeinflussten Standorten jedoch am geringsten. Die Konzentrationen leicht flüchtiger Kohlenwasserstoffe sind an einer verkehrsreichen Straßenkreuzung in Erding deutlich höher als im ländlichen Flughafenumland. Sie zeigen ausgeprägte Tagesgänge, die u.a. auf den luftchemischen Abbau zurückzuführen sind. Die Hydroperoxide als sekundäre Luftschadstoffe weisen einen gegensätzlichen Verlauf auf, der dem des Ozons mit nachmittäglichem Maximum ähnelt.

DOI: 10.1016/j.egypro.2016.10.027

show abstract

The energy-transformation towards renewable energies requires also storage systems to ensure security of supply. Motivated by strategies to implement renewables up to 100% at a regional scale, this paper presents a simulation of the power production from a virtual power plant based on 13 photovoltaic plants to integrate the “Power-to-Mobility”-technology, an innovative storage-technology to compensate fluctuating power production. The aim is to develop a simulation methodology with spatial-temporal and electrical parameters for a better management of the storage system. The project is work in progress but first results of the simulation show synergies between virtual power plants and Power-to-Mobility.

Simultaneous CO2 and CO methanation using microbes.

bioRxiv

  • (2018)

DOI: 10.1101/326561

show abstract

In this study, we developed a method for simultaneous bio-methanation of CO 2 and CO with H 2 in a single bioreactor using a combination of carboxydotrophic bacteria and methanogenic archaea for industrial applications. Methanogenic archaea generally use H 2 and CO 2 to produce methane, whereas very few methanogenic archaea methanize CO, and these grow slowly and consequently produce low reactant gas turnover rates. Thus, to achieve fast and simultaneous transformation of CO and CO 2 , we identified a combination of carboxydotrophic and hydrogenogenic bacteria and methanogenic archaea that can produce H 2 and CO 2 from CO, and then methanize CO 2 and H 2 . The present screening experiments identified carboxydotrophic bacteria and methanogenic archaea that can cohabitate at the same thermophilic temperature and pH ranges and in the same growth medium. In these experiments, combinations of Carboxydocella thermautotrophica (DSM 12326), Carboxydocella sporoproducens (DSM 16521), and three thermophilic rod-shaped methanogenic archaeal cultures from MicroPyros GmbH formed unique microbial co-cultures that transformed CO 2 , H 2 , and CO to methane. The successful combination of these microbes could be used to gasify biowastes, such as sewage sludge, as alternative sources of hydrogen for microbial power-to-gas processes. Accordingly, gasification under these conditions produced H 2 -rich gas containing CO 2 and CO, theoretically allowing various types of biowastes to be converted to biomethane, which is CO 2 -neutral, storable, and widely applicable as an energy source.

Biological CO2-Methanation: An Approach to Standardization.

In: Energies vol. 12 pg. 1670

  • (2019)

DOI: 10.3390/en12091670

show abstract

Power-to-Methane as one part of Power-to-Gas has been recognized globally as one of the key elements for the transition towards a sustainable energy system. While plants that produce methane catalytically have been in operation for a long time, biological methanation has just reached industrial pilot scale and near-term commercial application. The growing importance of the biological method is reflected by an increasing number of scientific articles describing novel approaches to improve this technology. However, these studies are difficult to compare because they lack a coherent nomenclature. In this article, we present a comprehensive set of parameters allowing the characterization and comparison of various biological methanation processes. To identify relevant parameters needed for a proper description of this technology, we summarized existing literature and defined system boundaries for Power-to-Methane process steps. On this basis, we derive system parameters providing information on the methanation system, its performance, the biology and cost aspects. As a result, three different standards are provided as a blueprint matrix for use in academia and industry applicable to both, biological and catalytic methanation. Hence, this review attempts to set the standards for a comprehensive description of biological and chemical methanation processes.

Energy Cell Simulation for Sector Coupling with Power-to-Methane: A Case Study in Lower Bavaria.

In: Energies vol. 15 pg. 2640

  • (2022)

DOI: 10.3390/en15072640

show abstract

In this study, the possibility of sector coupling with biological Power-to-Methane to support and stabilize the energy transition of the three major sectors of electricity, heat, and gas was addressed. For this purpose, the energy cell simulation methodology and the Calliope tool were utilized for energy system optimization. This combination provides detailed insights into the existing dependencies of consumers and fossil and renewable energy suppliers on a local scale. In this context, Power-to-Methane represents an efficient technology for quickly and effectively exploiting unused electricity potential for various sectors and consumers. It was found that, even in regions with low wind levels, this surplus electricity potential already exists and depends on various influencing factors in very different ways. The solar influence on these potentials was considered in connection with gas-fired cogeneration plants for district heating. It was found that the current heat demand for district heating produces a large amount of electricity and can generate surplus electricity in the winter. However, in the summer, large amounts of usable waste heat are dissipated into the environment, owing to the low consumption of district heat. This problem in the heat sector could be reduced by the expansion of photovoltaics, but this would require further expansion of storage or conversion systems in the electricity sector. This demonstrates that the consideration of several sectors is necessary to reflect the complexity of the sector coupling with Power-to-Methane properly.

Comparison of Various Reducing Agents for Methane Production by Methanothermobacter marburgensis.

DOI: 10.3390/microorganisms11102533

show abstract

Biological methanation is driven by anaerobic methanogenic archaea, cultivated in different media, which consist of multiple macro and micro nutrients. In addition, a reducing agent is needed to lower the oxidation-reduction potential (ORP) and enable the growth of oxygen-sensitive organisms. Until now, sodium sulfide (Na2S) has been used mainly for this purpose based on earlier published articles at the beginning of anaerobic microbiology research. In a continuation of earlier investigations, in this study, the usage of alternative reducing agents like sodium dithionite (Na2S2O4) and L-Cysteine-HCl shows that similar results can be obtained with fewer environmental and hazardous impacts. Therefore, a newly developed comparison method was used for the cultivation of Methanothermobacter marburgensis. The median methane evolution rate (MER) for the alternatives was similar compared to Na2S at different concentrations (0.5, 0.25 and 0.1 g/L). However, the use of 0.25 g/L Na2S2O4 or 0.1 g/L L-Cys-HCl led to stable MER values over consecutive batches compared to Na2S. It was also shown that a lower concentration of reducing agent leads to a higher MER. In conclusion, Na2S2O4 or L-Cys-HCl can be used as a non-corrosive and non-toxic reducing agent for ex situ biological methanation. Economically, Na2S2O4 is cheaper, which is particularly interesting for scale-up purposes.
