Industrial waste heat utilisation 12.9.2017

Foundry using waste heat of the furnace

In energy-intensive industries, e.g. foundry industry or cement industry, the use of waste heat for example as process or space heating energy reduces the consumption of primary energy.  In the Project “IAST” researchers are testing an energy storage system for discontinuous industrial waste heat of a furnace at a foundry. The implementation and commissioning is expected to start at the end of 2014. ... more

Analysis 1.2.2016

Standardising performance tests

Researchers from Fraunhofer UMSICHT are designing performance tests for battery storage systems. The tests are supposed to enable objective testing and comparison of different types of batteries for standardised and practical applications. Another goal is to apply these test cycles with a real lithium-ion battery and with a lead-gel or a redox flow battery for comparison. .

Magnesium sulfide - an alternative to lithium

Batteries should demonstrate a high energy density, they should be inexpensive and should hold many memory cycles. Scientists develop such batteries in the project MASAK. They pursue a new concept: in contrast to the known magnesium - systems not magnesium cation are used for charge transfer, but sulfide anion. ... more

Redox flow battery 1.8.2016

Liquid storage simplifies network expansion

Scientists of the project SmartPowerFlow integrated a large redox-flow battery into the power grid of a German operator. They wanted to find out to what extent energy storages increase the capacity of the grid and so reduce the cost of grid expansion. ... 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

Smart Grid 13.7.2016

Household appliances store heat

When refrigerators, washing machines or dishwashers store heat temporarily, they require less energy and can transfer their power consumption partly in low-load periods. A manufacturer of household appliances develops concepts for such products in cooperation with project partners from industry and research. The focus is on latent heat storages. ... more

Supply networks 4.10.2016

Coupling renewables with electricity and gas grids

In the KonStGas project scientists examined the potentials to integrate renewable energy sources, resulting from the coupling of energy networks. For this purpose, they model the energy flows of the total energy supply structure and evaluate the results from an economic perspective. They derive recommendations for the adjustment of energy infrastructure and future energy market. ... more

Increasing the energy density of thermal storages

Scientists optimise materials and components for soprtion-based thermal energy storages of high energy density. Sorption reservoirs for buildings currently achieve an energy density of about 130 kWh / m³. In the project MAKSORE the researchers want to achieve an effective usable volumetric energy density of at least 180 kWh / m³. ... more

Long-term storage 9.1.2017

Saisonal storage in aquifers

Aquifers have a large storage capacity and offer considerable potential as seasonal thermal or cooling storage systems. In a research project, researchers developed an improved storage concept for supplying heating and cooling energy to buildings and entire urban districts. For this purpose, they are combined the expertise from various specialist areas such as energy technology, geochemistry, hydrogeology, architecture and urban development. ... more
