Ökad användning utav batterilager : Identifiering av hinder och drivkrafter

The purpose of this work was to describe state of the electrical energy storage and to highlight the barriers and drivers for electrical energy storage in Sweden today. Sweden's electricity grid will soon undergo major changes. A more decentralized power grid and increased use of renewable energies demands new energy storage technologies. The ability to store energy will therefore be critical in the electrical grid that is now emerging. Battery prices have fallen drastically in the recent years and the interest for large-scale electricity storage batteries has increased. Multiple applications have been identified for large scale battery storage and there is an economic potential in these techniques. Against this background, there is reason to examine the situation of the development of electrical energy storage in batteries in the Swedish electrical grid. The central question of this report is: What barriers and driving forces can be identified for large-scale energy storage in batteries? To answer this ten interviews with an investigative interview method was made. As a theoretical framework, a research project called “Infrasystemets dynamik” was used. The researcher of that project is named Arne Kaijser and is associate professor at the department of technology and business history at the Institute of Technology in Stockholm. In his research Kaijser compares development of various kinds of large technical systems with the infrastructure function. Examples of such systems are transport, communications and energy. Conclusions In general it can be said that the participants considered it to be lack of interest and obstacles in the regulations that so far has prevented energy storage towards the grid. Initiatives from the Swedish Energy Agency was regarded to have been the only driving force for the large scale battery storage up until now. Overall it was said in the interviews that the elimination of obstacles in the regulatory environment and continued battery development might be what affects the ability of electrical energy storage in the future. Electrical energy storage will be needed and therefore it is important that long-term political goals for electrical energy storage can be formulated. To do that a good and broad debate is needed
