Central energy management system 9.1.2017

City as Storage

A central

management system in a City can make electricity producers and consumers work

together. The result is a virtual energy storage for the energy system.

Scientists developed a management system that bundles cogeneration systems, heat

pumps , night storage heaters, photovoltaic batteries and other equipment. .

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

Organic PCM 5.9.2016

Phase change material is crystallised

With micro-encapsulated or emulsified organic phase change materials, the solidification temperature is frequently below the melt temperature. This so-called undercooling is a hindrance for many applications. By means of systematic investigations, the researchers achieved a fundamental understanding of the physical principles. Based on the experimental findings, models developed that make it possible to forecast the crystallisation properties. ... 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

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

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

Absorption-storage system 12.4.2017

Drying with open sorption processes

A junior research group investigated heat and material transfer to an aqueous solution of lithium chloride. Such salt solutions can be used for air conditioning in buildings or waste heat. At the same time it serves as an energy storage. In addition to the salt solutions young researchers testing and synthesizing new sorbents. Also system simulations for building heating and air conditioning are planned in addition to drying applications. ... more

Liquid sorptionstorage 4.7.2016

Saline stores process and solar heat

Scientists at the University of Applied Sciences Stuttgart constructed an open air run sorption heat storage, that regenerates itself by process heat or solar thermal energy. Prototypes were developed, consisting of regenerator, absorber and the storage. These can be used for various cooling, heating and drying applications. By 2017, the storage is to be ready for the market. ... more
