Sorption heat storage 12.4.2017

Sorptive heat storage using activated carbon

Activated carbon can be produced from a large variety of carbonaceous source materials. Different methods have also been established for the process steps of carbonization and activation for use in commercial applications. In the project HyAcitv researchers optimize activated carbons and in a further step, molded articles are produced for use in open sorption systems. The application of these moldings is demonstrated in a laboratory storage system. .

Latent heat storage 18.1.2017

Increasing efficiency of power plants and electric arc steelworks

How can energy efficiency in industry and thermal power

plants be increased by using thermal energy storages? Researchers are studying

the integration of thermal storage in different industrial and CHP processes.

The focus is on high temperature storages with a storage temperature above 200

°C. A highlight of the project TESIN is the development, design, build,

commissioning and operation of a latent heat storage unit in the operating CHP

plant in Wellesweiler, Saarland of STEAG New Energies. ... 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

More efficiency through bulk movement

Chemical heat storage with Calziumoxid is being tested by Scientists of the DLR in the project BERTI. As a special feature, the laboratory unit of Stuttgart researchers has a wandering reaction bed. As a result the heat capacity of the storage and its heat output can be designed independently of one another. ... 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

Large-scale hot water storage tanks 12.4.2017

Segmental design reduces costs of storage tanks

Large-scale hot water storage tanks have proved to be reliable and efficient heat storage for cogeneration as well as for solar thermal plants and industrial processes. As part of the research project OBSERW, scientists try to reduce the construction costs of such storage tanks. To accomplish this goal they develop a segmental design for aboveground storage tanks from 500 to 8.000 m³ volumetric capacity. ... more

Power-to-Gas 12.4.2017

Gas and fuel from wind

Can wind be stored? Siemens, Linde, RheinMain University of Applied Sciences and the Mainz municipal utility company want to enable that during periods with no wind at “Energiepark Mainz” (Mainz Energy Park). For this purpose the researchers are producing hydrogen from wind energy. From 2015, it is intended to produce hydrogen using a Power-to-Gas plant at the newly developed Mainz Energy Park. ... more
