Thermal Energy Storage

In order to achieve CO2 reduction, the primary energy demand must be reduced and new energy sources must be developed.
Waste heat from industrial processes that has not been used so far can be utilised with the help of thermal and chemical energy storage systems, thereby reducing the use of primary energy. Thermal storage can also be used in conventional as well as solar power plants.
The focus the scientists are working on are thermal power plant components, liquid salt storage, energy conversion and thermal energy storage processes as well as thermochemical systems. ->more

Electrochemical Energy Storage

In order to be able to supply ourselves with renewable energies from sun and wind in the future, we also need electrochemical storage systems. These include batteries, fuel cells and electrolysers.
The three technologies can be used in a future energy system for both stationary energy supply and electromobility. ->more

Energy Storage Simulation

A detailed understanding of the underlying physical, chemical and fluid mechanical processes is a requirement for further improving the efficiency, durability and costs of fuel cells and batteries. In energy storage simulation, scientists use multi-scale and "multi-physics" models for this purpose. They are developed and applied at the institute. Special expertise is available in the area of microstructure-resolved simulation. The simulation models are developed and examined for fuel cells and batteries in order to then be able to derive conclusions for practical application. ->more

Energy Storage Integration

Efficient battery systems and effective, multifunctional fuel cell systems have to be developed for stationary and mobile applications. For this, suitable components must be selected and targeted system designs developed based on detailed modelling and simulation calculations. The customised system design is based on the specific application and its requirements, for example for on-board power generation (Auxiliary Power Unit - APU) for A320 aircraft and propulsion in aviation applications, for applications in the mobile sector or for stationary energy supply. The scientists' declared goal is to transfer their findings from basic electrochemical research to application. Established, industry-oriented and quality-assured development processes are taken into account. ->more

Thermal Storage Power Plants

Thermal storage power plants are thermal power plants equipped with a large thermal energy storage unit that is electrically heated. They can be charged using electricity from renewable sources and thus provide renewable energy “base load-capable”. ->more
