Economic Viability of Second Use Electric Vehicle Batteries for Energy Storage in Residential Applications
Energy Procedia, 2017Co-Authors: Reinhard Madlener, Alexander KirmasAbstract:Abstract We examine the economic viability of second use batteries from electric vehicles for load shifting and peak shaving in residential applications. We further investigate the expected impact of a growing number of residential storage systems on the electricity market. For the analysis a simulation model of a Private Household with integrated PV- storage system is used that is parametrized for an electricity demand of three people and a location in southern Germany. The conditions for which investments in second use batteries are profitable are examined for three scenarios. The central scenario S2 tackles an expected net increase in the electricity price by 4% per year. Upward and downward deviations from this price trajectory are covered by scenarios S1 and S3. For scenario S1, we find that investments in storage systems are profitable for all Li-ion battery costs assumed. In scenario S2, the breakeven battery price is found to be 107 €/kWh, whereas in scenario S3 with the lowest electricity price growth the battery price has to be equal or lower than 73 €/kWh to maintain economic viability.

Using phytoremediation technologies to upgrade waste water treatment in Europe.
Environmental Science and Pollution Research, 2007Co-Authors: Peter Schröder, Juan Navarro-aviñó, Hassan Azaizeh, Avi Golan Goldhirsh, Simona Digregorio, Tamas Komives, Günter Langergraber, Anton Lenz, Elena Maestri, Abdul R MemonAbstract:GOAL, SCOPE AND BACKGROUND: One of the burning problems of our industrial society is the high consumption of water and the high demand for clean drinking water. Numerous approaches have been taken to reduce water consumption, but in the long run it seems only possible to recycle waste water into high quality water. It seems timely to discuss alternative water remediation technologies that are fit for industrial as well as less developed countries to ensure a high quality of drinking water throughout Europe. MAIN FEATURES: The present paper discusses a range of phytoremediation technologies to be applied in a modular approach to integrate and improve the performance of existing wastewater treatment, especially towards the emerging micro pollutants, i.e. organic chemicals and pharmaceuticals. This topic is of global relevance for the EU. RESULTS: Existing technologies for waste water treatment do not sufficiently address increasing pollution situation, especially with the growing use of organic pollutants in the Private Household and health sector. Although some crude chemical approaches exist, such as advanced oxidation steps, most waste water treatment plants will not be able to adopt them. The same is true for membrane technologies. DISCUSSION: Incredible progress has been made during recent years, thus providing us with membranes of longevity and stability and, at the same time, high filtration capacity. However, these systems are expensive and delicate in operation, so that the majority of communities will not be able to afford them. Combinations of different phytoremediation technologies seem to be most promising to solve this burning problem. CONCLUSIONS: To quantify the occurrence and the distribution of micropollutants, to evaluate their effects, and to prevent them from passing through wastewater collection and treatment systems into rivers, lakes and ground water bodies represents an urgent task for applied environmental sciences in the coming years. RECOMMENDATIONS: Public acceptance of green technologies is generally higher than that of industrial processes. The EU should stimulate research to upgrade existing waste water treatment by implementing phytoremediation modules and demonstrating their reliability to the public.

Efficiency of Private Household Sand Filters in Removing Nutrients and Microbes from Wastewater in Finland
Water, 2018Co-Authors: Kati Martikainen, Anna-maria Veijalainen, Eila Torvinen, Helvi Heinonen-tanski, Ari Kauppinen, Tarja Pitkänen, Ilkka T. Miettinen, Ville MatikkaAbstract:Sand filters have been shown to be an economic and effective solution for wastewater treatment in Private Households, although the removal of phosphorus (P) may be insufficient. However, P removal can be improved by adding a P-adsorbing material, such as biotite, into the sand filters. The physico-chemical characteristics and the microbial quality of the effluents of family-scale sand filters without adsorbing media (SF), sand filters with a biotite layer (B), and sand filters with a modular filter (MB) were followed for one year. Sand filters with a biotite layer displayed the highest capacity to remove nitrogen (N) and biological oxygen demand BOD7. The efficiency of these filters did not depend on the age of the filter or the season. The P load of the effluent did not differ between sand filters with and without a biotite layer, but the modular sand filter failed to adequately reduce P. The treatment efficiency of sand filters without biotite decreased with increasing age. These Private Household sand filters can be a good way to treat domestic wastewaters, since these generally comply with the minimum requirements of a Finnish Decree (157/2017). However, enteric viruses (noro- and adenoviruses) were commonly found in the effluents, and the numbers of Escherichia coli were often above 103 colony forming units (CFU) 100 mL−1 (limit for the the EU Bathing Water Directive 2006/7/EC) for good water quality), signifying a risk of microbial contamination of nearby drinking water wells, as well as bathing and irrigation waters.
