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
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.
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.
