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

Performance Potential 1.4.2016

Forecasting the potential of caverns

What potential is there for energy storage in the salt structures of Northern Germany? This question is being addressed by researchers in the InSpEE project. They are investigated the planning bases and selection criteria for constructing salt cavern storage facilities. The researchers are also investigated how much compressed air and hydrogen can be stored in these. ... more

Study 31.3.2016

Energy Storage Systems in 2030

Which system infrastructure is most economic for the supply system? What will be the storage requirement in 2030? These questions addressed by scientists in the Merit Order study. For this purpose they recorded the characteristic values of possible storage technologies and distinguished them in regional terms. ... more

Salthydrates 14.3.2016

Cooling of buildings using new salthydrates

In the project PC-Cools_V two new phase change materials (PCM) on a salthydrate basis with a narrow melting range around 21°C and around 15°C are developed. The latter was intended for the implementation in central cold storages whereas the PCM melting at 21°C was designed for a decentral, room integrated storage application, especially cooling ceilings. ... more

Composites 16.2.2016

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

Latent heat storage 2.2.2016

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

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

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. .

Analysis 11.1.2016

Economic check for energy storages

How cost-effective are energy storages? Scientists at the University of Duisburg-Essen investigated how economic energy storages are and combine methods from financial mathematics with energy-economic and stochastic models. The procedure should be more reliable than the conventional deterministic models. ... more

Electrochemical Storage 31.12.2015

The potential of electrochemical storages

Scientist explore how electrochemical energy storages can make future electricity networks stable and secure. For this purpose, they analyse the technical and economic aspects of the use of these systems. In addition, they also consider alternative techniques – such as material storage, pumping and compressed air storage - and the possibilities of load management and network expansion. ... more
