Intelligent Use of Energy in Small and Medium-sized Industry – SEEDs

The basic idea of the SEEDs project is to reconstruct and optimize the local energy systems for small and medium-sized companies (industrial level) by utilizing and further developing existing approaches and techniques. The goal is to research, develop and implement sustainable energy production, energy storage, energy supply, and efficient energy use at a local industrial level. In this connection, the focus is on maximum efficiency, cost effectiveness as well as the security of supply and stability autarchy.

The areas covered in SEEDs are microgrids, energy storage, gas-to-power coupling, grid connection, load shift, sustainable creation, and the use of energy, as well as energy efficiency. The whole chain of energy technology is therefore investigated. Specific attention is paid to an efficient interlinking of power electronics and interfaces with different components of the local energy system, in order to set up a stable overall local energy system with respect to controlling. These interfaces are a core competence of Fraunhofer IISB. The Fraunhofer institutes IIS and ISC are also participating in the project. IIS covers communication-related topics, and ISC handles material aspects for electrical battery development.


The main institute building of the Fraunhofer IISB serves as a research and demonstration platform. The requirements for different energies (heat, cold, and electricity) as well as the range, infrastructure, and energy consumption of the IISB are comparable to those of small and medium-sized companies. IISB shows a high load fluctuation, high peak loads, and a substantial need for secondary energy due to a considerable amount of labs and equipment for semiconductor processing as well as manufacturing. A clean room is in continuous operation, and a large number of labs and offices are in use. Therefore, the IISB platform covers office as well as industrial and lab aspects, which means that nearly all facets of energy management and the energy sector of a local energy system are dominant. Production-related activities are continuously performed, but no direct production cycle will be disturbed for research and development. Therefore, this research and development platform seems to be ideal for applications such as research and demonstration activities.

The activities and highlights of the project are described in detail on the website
