The stated aim of the German federal government is the market preparation and launch of battery electric vehicles in Germany. The potential of electric vehicles for reducing the harmful environmental impacts of road transport in everyday conditions has to be analyzed and evaluated in detail. If electric vehicles shall realize their potential to reduce emissions and minimize the consumption of resources, the use of renewable energy is necessary. Locally generated and stored energy could increase the use of renewable energy sources for electric vehicles. A quantitative method is necessary to determine if the use of local energy is environmentally advantageous in comparison to the use of renewable energy from the grid. Life cycle assessment is a method which quantifies potential environmental impacts, and, therefore, it is a suitable method to examine the research question. The local energy provider BS/ENERGY uses electric vehicles and plans on the installation of a stationary energy storage. Within this scenario the LCA method is applyed to analyze the environmental impacts of this solution.This work carries out a detailed life cycle assessment for the local energy storage system of BS/ENERGY. To support this work a theoretic background of the method life cycle assessment and of the local generation and storage of renewable energy is presented. Based on this information, a generic workflow for the LCA of the use of locally generated and stored energy for electric vehicles is created. This workflow serves as a basis to evaluate the key parameters for the result of the LCA, identifying hot spots and uncertainties. Finally, the specific case of BS/ENERGY is analyzed, with its specific battery chemistry and use pattern. With this, it is expected that the presente work will be able to support BS Energy decision of whether to invest on the stationary battery or not, from an envirionmental point of view.
