    Pilot production launched for superconductors

    He had to wait 30 years for this moment: Dr Georg Bednorz, a Nobel Laureate in Physics, was present in the Rhineland town of Rheinbach to see the pilot production of high-temperature superconductors begin. It is intended to provide further insights into the manufacture of these almost resistance-free conductors and pave the way for their large-scale series production. The technology is therefore taking a further step towards market maturity.  more...
     

    Storing heat until winter

    To be able to use summer heat for heating during the winter, hot water storage systems have to be very large. Small storage systems cool down too quickly. With this in mind, seasonal storage tanks have been developed almost exclusively for housing estates or very large consumers. Now researchers have created a new long-term storage system which is also suitable for single-family homes.  more...
     

    The building serves as a heat storage tank

    Buildings with high solar shares of fraction require large water tanks to store heat. Researchers have developed a space-saving alternative: excess heat is stored in the ceilings of the building via building element activation. Scientists are currently testing the concept in an experimental building near Hanover. They now have the results of the first year of operation.  more...

    Mechanical mass production of rotor blades

    The rotor blades of wind turbines are still mostly made by hand. This is due to the low piece numbers involved. So how would it be possible to produce them faster, cheaper and with a greater degree of precision? Automated production is now possible in the BladeMaker factory in Bremerhaven. Eight process steps are combined into a single step. The production facility has now been inaugurated.  more...
     

    BINE interview with Professor Dr. Siegfried Heier

    Further developments of converter technology will be necessary for wind turbines to support any grid improvements. Decentralised coupling and decoupling of power ought to be possible in the future high-voltage direct current (HVDC) electric power transmission system. In this BINE interview, Professor Dr Siegfried Heier lists future focal points of technological development in the wind energy sector.  more...

    Energy storage systems in 2030

    What role will functional storage systems play in the energy supply system of the future? Which system infrastructure can economically secure a reliable energy supply in 2030? And what measures must the government take so that this system infrastructure can prevail on the market? Scientists at the Research Center for Energy Economics (FfE) are trying to get to the bottom of these questions with an ongoing study. The results are now available.  more...
     

    Energy-efficient use of university buildings

    Using the Ludwig Maximilian University of Munich as an example, researchers want to show how efficiency improvements can pave the way for a climate-neutral university campus. In the project HoEff-CIM, the buildings are reproduced and evaluated in a model with the aim of developing appropriate refurbishment strategies and an energy management system for building operation.  more...
     

    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...
     

    Wind turbines are becoming quieter

    Wind turbines are not allowed to disturb neighbouring residential buildings through the noise that they emit. Wind turbines therefore have to be kept at a distance from settlements. To further reduce and better predict noise emissions, the University of Siegen has now launched a research project. In this project, the scientists want to modify the trailing edges of the rotor blades. They also want to develop better sound forecasts for entire wind farms. Quieter wind turbines would enable more land to become available for wind power generation.  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...
