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

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

Lithium combustion 30.9.2015

Lithium, the renewable coal

Lithium can be used for chemically storing electricity as part of a cycle in which it is first generated electrochemically using surplus electricity and then combusted as required in a power plant-compatible process to release the energy again. In the “LiKohle” project, researchers are investigating and assessing the possible reaction processes, for example in a carbon dioxide or nitrogen atmosphere. Valuable chemical raw materials can be generated as a by-product of the energy conversion. ... 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

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

New economical phase change material

Scientists at the University of Bayreuth are optimizing mobile latent heat storages. In the project MALATrans they improve charging and discharging capacity of the heat storages and analyse how the manufacturing costs can be reduced. The phase change materials they are working with are macroencapsulated. ... more

Active coatings for heat storage

The young researcher group NEOTHERM constructs novel sorptive heat storage materials for better use of solar heat for domestic heating and the reuse of industrial waste heat. For this purpose the scale-up of suitable materials is investigated. The products could be implemented in solar thermal energy systems or in waste heat recovery devices. Special composites could also be used in heat pump applications for air conditioning. ... more

Thermochemical storage 21.4.2016

Metal hydrides store faster with graphite

Many metal alloys can reversibly bind large amounts of hydrogen, forming metal hydrides. The chemical reaction releases large amounts of heat. Metal hydrides are therefore suitable not only for hydrogen storage but also as thermochemical heat storage. Metal hydride storages achieve extremely high charging and discharging performances by a combination of metal hydrides with thermally conductive graphite in a composite material. ... more
