HyINTEGER 18.4.2017

Long-term underground storage of hydrogen

In the H2STORE project, scientists established that hydrogen can induce rock alterations under specific conditions. However, the gas can also cause alterations to other materials, such as steel alloys. Therefore, in the HyINTEGER follow-up project, the researchers are now investigating the interaction between the technical and natural reservoir components. ... more

Elektrolysis 12.4.2017

Hydrogen production in the megawatt-scale

In the P2G electrolysis project, researchers worked on developing and testing an optimised H2 generation plant prototype based on alkaline electrolysis technology in the 300 kWel class. Based on the currently available AEL technology, it is intended to exploit the development potential technically necessary for the entire plant and prepare the upscaling to the lower megawatt class. ... 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

Redox-Flow-Battery 12.4.2017

Energy from tubes

In the joint tubulAir project, scientists are developing a new redox flow battery type for stationary applications. This is intended to be cheaper to produce while having a considerably greater output and energy density. The new system works with just one electrolyte solution in combination with compressed ambient air. Also new is the geometry of the cells, which are constructed as micro-tubes. ... more

Pump storage StEnSEA 12.4.2017

Storing energy at sea

The project “StEnSEA” (Stored Energy in the Sea) is investigating the installation of large storage facilities on the sea floor, in combination with offshore wind farms. The physical principle is similar to that of conventional pumped storage power plants, but based not on two reservoirs, but a hollow sphere. The inflowing water drives a turbine to generate electricity. When there is a surplus of electricity in the grid, part or all of the water is pumped out of the sphere. The commercial target size per sphere is currently at about 20 MWh per storage unit. .

Industrial waste heat utilisation 12.4.2017

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

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

Decentralised battery storage 12.4.2017

Battery System for owners and the grid

In the project PV-host scientists want to improve decentralized storage battery technically and economically. To this end, they compare solar storage that are suitable for detached houses. They want to find out which operating strategy operates useful with a memory as possible network. The storage will not only meet their own needs of the household, but also reduce feed-in peak. This is to ensure that the network can accommodate a total of more electricity from solar installations. ... more

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 12.4.2017

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
