Energy storage - research for the energy revolution

In the medium to long term, the use of storage systems will become increasingly important in line with the constantly increasing proportion of renewable energies. The “Energy Storage Funding Initiative” was established of the German Federal Ministry of Economic Affairs and Energy (BMWi), the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB) and the Federal Ministry for Education and Research (BMBF).
As part of the 6th Energy Research Programme by the German Federal Government, the ministries have set aside around 200 million euros for research projects in the first phase up to 2014. The aim is to further develop a wide range of storage technologies for electricity, heat and other energy sources.

  • Zinc-air batteries for the grid

    In the ZnPLUS project scientists develop an economic zinc-air storage system in the megawatt range. more

  • ENREKON: Capacitors research

    With ionic liquids and transition metal oxides researchers develop a resource-efficient condensers for short-term energy storage. more

  • Segmental design for energy storage

    As part of the research project OBSERW, scientists try to reduce the construction costs of large-scale heat storage tanks. more

Electricity storage systems in the cloud

green2store: Field test started

The green2store project shows how energy storage systems can be bundled together in a virtual cloud. For the next twelve months, a local network storage system and nine home storage systems will be interconnected with one another in a cloud. The field test has now commenced...

Greater current density for zinc-air batteries

Rechargeable zinc-air storage systems have yet to achieve satisfactory charge and discharge cycles. This provides the starting point for the ZnPLUS project: researchers have increased the current density by using a modified zinc slurry. This makes the batteries easier to maintain and improves their performance reliability – with simultaneously lower costs...

Vanadium Redox Flow

Large-scale storage system begins operation

In the Smart Power Flow project, scientists are testing the use of a large vanadium redox flow battery in a local low-voltage grid. The local storage system recently commenced operation in Tussenhausen in Bavaria. ...

Vanadium redox flow batteries

New design reduces costs for bipolar plates

Redox flow batteries have a relatively complex structure and are prone to error. Researchers have therefore now integrated a bipolar plate directly into a stack. This saves on components and at the same time reduces costs. In addition, it makes the system easier to assemble and more reliable.

World’s largest electrolysis plant

Energiepark Mainz inaugurated

At Energiepark Mainz, Linde, Siemens, RheinMain University and the Stadtwerke Mainz municipal utility company are producing large amounts of hydrogen by renewable means. Four adjacent wind turbines take over the largest part of the electricity generation. The hydrogen can be stored on site, transported in tanks or fed into the natural gas network for the subsequent generation of electricity or heat. The world's largest electrolysis plant of its kind has now been inaugurated...

Conference report on the 2nd status seminar on energy storage systems

Interim findings of the Energy Storage Research Initiative

Which contribution can energy storage systems make to the energy transition? How can they be employed economically? And what are the future research priorities? These were the questions answered during the 2nd status seminar on energy storage systems in Berlin last week. Half-time for the Energy Storage Research Initiative, and time to look at the score.

Power station supplies valuable raw materials

Scientists are examining the use of alkaline metals and alkaline earth metals as potential fuels for power station processes. As an example, they have constructed a laboratory reaction chamber for burning lithium. The experimental lithium burner achieved a thermal capacity of 30 kilowatts. It atomises and burns melted lithium in a carbon dioxide atmosphere to produce lithium carbonate. Carbon monoxide is also produced. ...

Flexible electricity supply

Gas and heating networks store electricity

Germany’s electricity provision needs to be made more flexible in future in order to integrate the increasing proportion of fluctuating renewable energy. Heating and gas networks can already balance out some of these fluctuations and help to stabilise the future energy system. In the Multi-Grid Storage project, scientists at Fraunhofer IFAM have investigated how the energy from the surplus electricity can be stored as heat or gas, and then made available again as electrical energy when required. ...

ENREKON young investigator group: experts in interview

“We’re marketing renewable energy with storage systems”

The “Sell or Store” study shows that energy storage systems make a significant contribution to the economic integration of renewables in the market, whereby the connection, efficiency and size play a surprisingly small role. Dr Stephan Krohns, head of the ENREKON young investigator group, operations research expert Dr Jochen Gönsch and econometrician Michael Hassler speak in an interview about the revenue-oriented use of energy storage systems and how they can be utilised to stabilise the power grid. ...
