Flagship of the funding initiative

Batteries in the distribution grid

The projects range from batteries connected to photovoltaic systems in households to electricity storage facilities capable of storing megawatts of power which can be used by energy supply companies. Key research topics include electrical or electrochemical systems for storing electrical energy, such as batteries, redox flow or double-layer capacitors, and mechanical storage systems, such as compressed air storage, pumped storage power plants or flywheels. Other projects being funded include new storage concepts and research into connecting decentralized storage systems.

Analysis 1.2.2016

Standardising performance tests

Researchers from Fraunhofer UMSICHT are designing performance tests for battery storage systems. The tests are supposed to enable objective testing and comparison of different types of batteries for standardised and practical applications. Another goal is to apply these test cycles with a real lithium-ion battery and with a lead-gel or a redox flow battery for comparison. .

Analysis 11.1.2016

Economic check for energy storages

How cost-effective are energy storages? Scientists at the University of Duisburg-Essen investigated how economic energy storages are and combine methods from financial mathematics with energy-economic and stochastic models. The procedure should be more reliable than the conventional deterministic models. ... more

Stationary Energy Storage Systems 3.9.2015

Zinc-air batteries for the grid

Until now, zinc-air batteries have mostly been used as small disposable batteries, for example for hearing aids. The electrochemical reaction of zinc with atmospheric oxygen offers, however, considerable potential for building rechargeable storage systems with a high energy density for large energy volumes. Until now it has not been possible to implement it technically. In the “ZnPLUS” project, scientists want to utilise new concepts and components to develop an economic zinc-air energy storage system in the megawatt range. ... more
