Researchers in Germany have developed a renewable energy storage system capable of providing onsite storage for locally-produced energy.
Researchers of the EEBatt project, funded by the Bavarian State Ministry of Economic Affairs, have developed the ‘Energy Neighbor’ – a stationary battery storage system designed to reserve locally-generated energy to meet demand during times of high consumption.
In recent years, roof-mounted solar panels have proven exceptionally popular in parts of southern Germany. However, during peak times, more power is produced than can be consumed and storage remains an issue. At other times residents are forced to draw on electricity from trans-regional grids.
Bavaria’s Minister of Economic Affairs and Energy, Ilse Aigner, said, “Further development of storage technologies is an important element of the energy transition.”
In the past the expansion of renewable energy has been limited by the need to meet consumer demand during times when production is low. It is hoped that energy storage devices such as the Energy Neighbour may hold the solution to balancing performance peaks experienced by renewable systems with the consumption peaks of households.
The device has a current storage capacity of 200 kilowatt-hours, and is capable of holding 250 kilowatts of electrical power.
“In our field test we intend to gather insight from actual operation and apply it to the advancement of storage systems,” says Andreas Jossen, project leader and professor for Electrical Storage Technology at the Technical University of Munich, one of the institutions involved in the project.
