Sorptive heat storage
An important contribution to the achievement of climate protection targets is an improved utilization ratio for both fossil and regenerative primary energy sources. This is done by secondary usage of energy which was not used during its first application. A case in point is the utilization of waste heat created by combustion engines during the generation of power from biogas. The waste heat produced typically makes up over 50 percent of the energy content of the biogas.This not only shows the great potential which lies in the increase of the degree of efficiency, but also the need for temporal and spatial decoupling of secondary energy utilization. In addition, there are many more processes in commerce, energy supply and manufacturing industry which generate large amounts of waste heat. To optimize energy efficiency of processes, there is a need for compact and flexible storage systems to decouple or compensate the supply and demand for heat in terms of location through mobility and with regard to time through minimization of heat loss

Chemical energy storage
The cooperative project between Fraunhofer IGB BioCat (Straubing) and Fraunhofer UMSICHT (Sulzbach-Rosenberg) "Center for Energy Storage" aims at the systematic development of the neccessary technologies for the middle- to long term storage of energy in liquid energy carriers and heat storage media. The focus of Fraunhofer IGB Biocat is the development of catalysts and processes for the conversion of electric energy and CO2 in liquid energy carriers. Fraunhofer IGB BioCat uses and combines the whole spectrum of catalysis (heterogeneous, homogeneous, bio-, and electrocatalysis). The main criteria for the developments are: high energy efficiency, scalability, possibility for decentral operation, flexibility for intermittent operation. A prominent, first-of-its-class example is a process and system, which combines the conventional CO2-based methanol synthesis with the methanol fermentation to longer chain hydrocarbons. The patent application describing this process was recently accepted. The Fraunhofer IGB BioCat offers its services in the areas of (bio)catalyst development, screening and long term testing of catalytic properties, analytics, upscaling.
The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB develops and optimizes processes and products in the fields of health, chemistry and process industry, as well as environment and energy. We combine the highest scientific standards with professional know-how in our competence areas – always with a view to economic efficiency and sustainability. Our strengths are offering complete solutions from the laboratory to the pilot scale. Customers also benefit from the cooperation between our five R&D departments in Stuttgart and the institute branches located in Leuna, Straubing and Würzburg. The constructive interplay of the various disciplines at our institute opens up new approaches in areas such as medical engineering, nanotechnology, industrial biotechnology, and environmental technology.
