Energy storage systems – research for the energy transition

With the continuously rising share of renewable energies in the energy supply system, storage systems for electrical and thermal energy are becoming ever more important. If electricity is converted before it is stored, for example into hydrogen or other chemical energy sources, this energy can then be used in other energy industry-related sectors and thus for the much-needed coupling of the various sectors, all in addition to re-electrification of stored energy.

To date, however, only few storage technologies have reached the necessary technical maturity at a competitive cost level. The Federal Ministry for Economic Affairs and Energy and the Federal Ministry of Education and Research have recognised the research and development needs in the area of energy storage technology and are developing tailored promotional activities as part of the 6th Energy Research Programme of the Federal Government. With the Energy Storage Funding Initiative, both ministries have been supporting innovations for a wide range of storage technologies since 2011. But development is ongoing: the two ministries are pursuing new storage concepts and are further advancing existing technological developments also beyond the Energy Storage Funding Initiative.

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.

Electricity storage facilities

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. ...

Focus on the hydrogen storage process chain

In the PlanDelyKaD project, scientists studied the option of storing surplus electricity as hydrogen and converting it back for use. They considered the entire process chain from generation to storage and use. The research focused on hydrogen electrolysis and gas storage in salt caverns. The study completed in May 2014 reveals the method’s potential on the market. ...

Modular 5-megawatt battery storage system

The world’s first modular battery storage system with a performance class of five megawatts is being built in Aachen. This shall use lithium-ion batteries for, for example, short-term power storage, high-temperature batteries across several hours and lead-acid batteries for short and medium discharge times. Construction of the large-scale storage system is scheduled to begin in autumn 2014. ...

“PV Benefit” research project

Private solar power storage systems can relieve the grid

The range of battery storage systems for photovoltaic installations is growing dynamically. The benefits offered by these storage systems for both solar system operators and the entire energy system were therefore discussed by solar and storage experts in December 2013 in Frankfurt am Main. Their conclusion: Decentralised solar power storage systems in private households could provide one of the few functioning business models for stationary battery storage systems for the foreseeable future. ...

Storing solar energy with new materials

The interdisciplinary NEOTHERM junior research group at Otto von Guericke University in Magdeburg is developing new materials for storing thermal energy. Using new composite materials, the scientists at the Faculty of Process and Systems Engineering (FVST) want to recover and store unused solar thermal energy and waste heat from industry. This energy can be used, for example, for heating domestic hot water or for space heating. .

Electricity grid makes island self-sufficient

The North Frisian island of Pellworm has been a showcase for energy research since the early 1980s. In 1983, Europe's largest solar farm was built there. In 1989, wind turbines were added to create Europe’s largest hybrid power plant. A smart electricity grid will now make the island power-independent. ...
