Thermal Storage | BMBF
Materials and components 15.3.2017

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

Hydrogen electrolysis 3.3.2017

Green H2: Producing low cost and load-flexible hydrogen

Innovative electrodes improve hydrogen electrolysis for a wide output range. With their laser-etched surface structures, they are durable and have lower losses at different loads. As a result, the electrodes are particularly good at using the fluctuating supply of excess wind electricity. If upscaled, the structured electrodes can also be used in industrial applications. ... more

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

Lithium batteries 16.1.2017

Quantum mechanics replaces laboratory experiment

To get a better understanding of Li-Ion batteries, junior researchers are using quantum mechanical methods. The multiscale modelling of batteries, which is based on quantum mechanical principles, is an option to develop electrodes and electrolytes using computer-based simulations. The virtual development of batteries is not only accurate and fast, but also offers other benefits, since the costs are lower than those of laboratory experiments. In this way one single experiment can be sufficient to confirm the computer-based results. ... more

Analysis 9.1.2017

Determining the potential of the substructure

In the ANGUS+ project, scientists examine the potential for energy storage in the geological subsurface. In addition to the storage options for natural and synthetic methane, hydrogen and compressed air in caverns and porous formations, the storage of heat in the shallow subsurface is investigated. ... 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

Analysis 9.1.2017

Super batterie combines high performance and capacity

In the project NovaCap scientists determine in a study new materials for the realization of a new concept for hybrid and asymmetric supercapacitors. The concept provides for battery electrode material with capacitor material in one cell unite. This will create a super battery that combine both: high performance and high capacity. ... more

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. .

Battery fuel cell drive 8.11.2016

Hybrid power supply for municipal vehicles

Which electricity storage system will be used in future to drive and work electric municipal vehicles? The scientists in the ELAAN project are testing this and are combining the advantages of batteries with those of a fuel cell range extender. They are testing the concept on a demonstration vehicle with previously developed components that include the battery module, fuel cell subsystem, electric motor and associated power electronics. The demo vehicle is scheduled to be completed in spring 2017. ... more
