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

Capacitors 10.12.2014

From power grid to fundamental research

In

the ENREKON project, which stands for the “Development of resource-efficient

condensers for short-term energy storage”, researchers are synthesising ionic

liquids and transition metal oxides. Following this, a physical and structural analysis will be performed. Important capacitor-specific characteristics will be determined with dielectric spectroscopy over a wide temperature- and frequency range. ... 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

Analysis 24.9.2015

Storages in grid-connected PV systems

Photovoltaik storages can specifically relieve the grids and reduce the net expansion to a necessary measure. Which use PV storages have, depends on the operating method of the storage and the grid. First results gives the analysis "PV Benefit". .

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. .
