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

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

Latent heat storage based on salt 18.7.2016

„SALSA“ makes steam and waste heat useable

The Fraunhofer Institute for Solar Energy Systems ISE, Novatec Solar and Köllemann are developed a salt-based latent heat storage called SALSA. This is to used for waste heat recovery in industrial processes. In the end of 2016, the storage was integrated and tested in the southern Spanish power plant PE1. ... more

Thermochemical solid heat accumulators 1.2.2016

Heat storage in smallest volume

Thermochemical heat storage can achieve low cost because of its higher specific energy density as compared with conventional heat storage materials. However, the thermal conductivity of the material is limited. Therefore, scientists at the Fraunhofer UMSICHT developed new thermochemical storage materials. The researchers intend to increase the thermal conductivity of solids, specifically through the addition of special additives. ... more

Phase-change material (PCM) 11.4.2017

Increase dynamism with three-dimensional wire mesh

To equip modular storage units for a temperature range of 150 to 350 degrees Celsius and achieve high energy and power densities at the same time, is the declared aim of the researchers in the MOSPEDRA-project. The scientists first need to increase the dynamics of the memory modules. They want to achieve with a new metallic thermal wire mesh, which is embedded in a phase-change material. ... more

Pourable PCM for high temperatures

Dresden researchers develop small pourable and pumpable heat storage capsules for the temperature range from 130 to 350 ° C. The hollow spheres are made from metal alloys. Depending on the application, the diameters vary from 2 to 6 mm. The capsules contain salt mixtures for latent heat storage. ... more

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

Latent heat storage 1.10.2015

Waste heat used for production of precast concrete

Researchers develop new components in the project ENBELAT. To use the hydration heat they provide concrete precast molds with a heat recovery and save the heat in a latent heat storage. This increases the quality and helps the energy consumption to be reduced 45 percent. ... more

PCM storage 12.4.2017

Cheaper slurries for cooling processes

In order to reduce the cost of PCM storages, scientists develop new slurries and materials for cold storages. The aim of the project KOLAN is to develop an emulsion with a very high heat capacity. At a temperature difference of 6 Kelvin it should store about four times more heat than water. ... more

Double layer capasitors 1.9.2016

Activated carbons increase energy density

Scientists develop new electrode materials for high-efficiency double layer capacitors within the project ActivCaps. In contrast to purely empirical investigations they will characterize the structur of the materials at the nanoscale and will adjust simulation algorithms to the materials. The developed simulation tools can then be used for development of materials. ... more
