The aim of the study was to conduct a comparative ecological and economic evaluation of three selected decentralised stationary energy storage solutions in an interdisciplinary approach. The comparison was carried out using a concrete application scenario in industrial production and is therefore primarily aimed at small and medium-sized enterprises (SMEs) with energy-intensive processes. Among other things, it was clarified how the raw material and energy costs as well as the climate-damaging emissions are to be evaluated over the life cycle of the energy storage systems and what costs arise from their use. The results of the study are intended to enable SMEs to assess the usefulness of investing in stationary energy storage systems from an ecological and economic perspective.

The study was carried out by Öko-Institut e. V. in cooperation with IZT - Institut für Zukunftsstudien und Technologiebewertung gemeinnützige GmbH.
