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.

Power-to-Storage 3.5.2017

MeMO - a novel high-temperature battery

Forschungszentrum Jülich is developing a novel kind ot high-temperature battery. In this Power-to-Storage / Storage-to-Power concept, surplus electrical energy is stored by reduction of a metal oxide and regained by oxidation of the metal. The stacks have been operated for more than 200 redox cycles successfully. ... more

Redox-Flow-Battery 12.4.2017

Energy from tubes

In the joint tubulAir project, scientists are developing a new redox flow battery type for stationary applications. This is intended to be cheaper to produce while having a considerably greater output and energy density. The new system works with just one electrolyte solution in combination with compressed ambient air. Also new is the geometry of the cells, which are constructed as micro-tubes. ... more

Pump storage StEnSEA 12.4.2017

Storing energy at sea

The project “StEnSEA” (Stored Energy in the Sea) is investigating the installation of large storage facilities on the sea floor, in combination with offshore wind farms. The physical principle is similar to that of conventional pumped storage power plants, but based not on two reservoirs, but a hollow sphere. The inflowing water drives a turbine to generate electricity. When there is a surplus of electricity in the grid, part or all of the water is pumped out of the sphere. The commercial target size per sphere is currently at about 20 MWh per storage unit. .

Decentralised battery storage 12.4.2017

Battery System for owners and the grid

In the project PV-host scientists want to improve decentralized storage battery technically and economically. To this end, they compare solar storage that are suitable for detached houses. They want to find out which operating strategy operates useful with a memory as possible network. The storage will not only meet their own needs of the household, but also reduce feed-in peak. This is to ensure that the network can accommodate a total of more electricity from solar installations. ... more

Power-heat systems 12.4.2017

Network storage with hybrid photovoltaic system

Researchers develop new strategies for the operation of hybrid photovoltaic systems in residential buildings and small businesses. For this purpose, the scientists optimize the operation management by simulations and laboratory measurements in the project INE-VES. The optimized operations management will increase the benefit of the system for the power grid, as well as for the owner. ... more

Flywheel energy storage systems 12.4.2017

New design reduces system costs

Flywheel energy storage systems can play an important role in stabilising the electricity grid. When required, they provide high outputs within milliseconds. The short-term electricity storage systems also act as active voltage filters for optimising the electricity quality. In the KoREV-SMS project, scientists are developing a flywheel energy storage system with an external rotor design. This results in a higher energy density with lower acquisition costs compared to conventional flywheel energy storage systems. .

Energy storage flywheels 12.4.2017

Faster power storage with high cycle rate

Energy storage flywheels as short-term intermediate storage for regenerative energy generation systems can help keep the power grid stable. With good efficiency, they absorb or emit high power levels – while at the same time having an extremely durable cycle. In the ENERSPHERE project, scientists are working on a flywheel rotor with a superconducting bearing. This makes it extremely intrinsically safe and robust. .
