    Stadtwerke Augsburg testing superconducting fault current limiter

    The ASSIST project shows how decentralised feed-in systems can be safely integrated into a medium-voltage network. Since 15 March, a superconducting fault current limiter ensures that the electricity fed from a cogeneration engine test rig into the electricity grid belonging to Stadtwerke Augsburg municipal utility company is protected against short circuits. Last week, Thomas Janetscheck from Stadtwerke Augsburg presented the system at the ZIEHL V superconductor conference in Munich.  more...
     

    TU Darmstadt opens research factory

    Last week, the ETA model factory officially opened its doors. Here, scientists at the Technical University (TU) Darmstadt are researching under real conditions and at full scale how industry can use energy more efficiently by linking all building and production components. By considering the entire system – consisting of machines, energy storage systems, building technology and the building envelope – the intention is to reduce the primary energy requirement in production by 40 per cent.  more...

    Thermoelectrics: power from waste heat

    Waste heat is produced in all areas of daily life – in industry, homes and transport. In Germany alone, this adds up to a waste heat potential of 300 TWh per year. This energy volume corresponds to nearly half the total energy consumed by German industry. Thermoelectric generators (TEGs) can tap into this huge energy reservoir and transform the "waste energy" without moving parts into a higher form of energy.  more...

    Once coated, everything runs smoothly

    The wear and energy consumption of machinery increase dramatically if the machines are not optimally lubricated. In many cases, however, ideal lubrication is impossible, for example, in free-running motorcycle chains or agricultural machinery. To meet these operating conditions, researchers are therefore developing new coatings, and lubricants adapted to them, as part of the CHEOPS3 project. The twelve project partners from industry and science want to achieve long-term protection against wear, even with minimal lubrication and dry friction, so as to increase the efficiency of machines.  more...
     

    Neckarpark Stuttgart: Heat from waste water

    Sewage stinks and is filthy – but it is suitable for supplying heating and cooling to buildings. In Stuttgart’s new Neckarpark urban district, the energy in the municipal waste water is extracted by means of a trough heat exchanger in the sewage channel and utilised via a low-temperature local heating network. This provides the basis of the energy concept for the new district, which is being created with highly energy-efficient buildings on the brownfield site belonging to the former Bad Cannstatt railway freight depot.  more...

    Hybrid building machinery

    Hybrid drives make construction machinery not only more economical and quieter – the power from the two engines also provides power reserves for special loads. The advantages of combining a combustion engine with an electric drive have been demonstrated by the DEUTZ engine manufacturing company from Cologne using an excavator. In order to realise the full savings potential, the engineers have also closely examined the auxiliary units as part of the Green Industrial Diesel (GRID) project.  more...

    Processing solar cells with lasers

    Laser technology enables solar cells to be produced with greater efficiency. It replaces or eliminates costly processing steps that were previously required. Researchers have developed a method for laser contacting the rear side of solar cells that can be integrated into existing production lines for screen printing solar cells. The new technique enables the cells to be produced at a lower cost, reduces the energy and materials deployed, and eliminates previously required environmentally harmful chemicals.  more...

    Thermal storage systems brought into shape

    Thermal storage systems that utilise zeolite are still very rare. In a research project, scientists have investigated aluminosilicates for their practical use in thermal storage systems. They have succeeded in significantly improving the energy density, cycle resistance and thermal performance. The research has led to the development of a thermochemical storage system for a CHP power plant.  more...
     

    Series production of superconductors starts

    The end of the research project marks the beginning of mass production: Theva aims to develop a mass market for superconductors with its new production facility. The manufacturer wants to provide a resistance-free conductor that can be quickly adapted to different application areas. Until now the applications have been limited to niche uses.  more...
     

    Superlubricity reduces friction

    The forces of friction play a central role in vehicles. They inevitably lead to higher fuel consumption and wear in and on all moving parts. Researchers are therefore searching for ways to keep the forces of friction as low as possible. One area of research is diamond-like carbon coatings (DLC). In an interview, Dr Johann Schnagl, Project Manager in the BMW Group and Professor Dr Michael Moseler from Fraunhofer IWM explained this area of research.  more...
