    Pilot production of thermoelectric modules

    Thermoelectric generators convert waste heat directly into electricity. They utilise temperature differences and are paving the way for more energy-efficient production processes. However, the technology has previously led a niche existence because the module production is labour-intensive and therefore expensive. Researchers from Freiburg now want to improve this.  more...

    Hydrogen – storing energy in metals

    Metal hydrides store hydrogen and heat. Their use in thermochemical storage systems is hampered, however, by the material's poor heat conductivity. To increase the charging and discharging performance, researchers are pelletising the material together with graphite, which has a high thermal conductivity. With different metal hydrides they can cover the temperature range from room temperature up to 400 degrees Celsius.  more...

    First liquid salt storage facility with one tank

    High-temperature heat storage tanks ensure that power plants work more flexibly and industrial process heat can be temporarily stored. Researchers at the German Aerospace Center (DLR) have therefore developed a heat storage tank for temperatures up to 560 degrees Celsius, which stores the heat in molten salt. Construction work on the testing facility began at the start of July 2016.  more...

    A town acts as a storage system

    How can urban regions contribute more to the energy transition? To find this out, scientists are investigating virtual energy storage systems in Herten in North Rhine-Westphalia and in Wunsiedel in Bavaria. The field trial started on 30 June 2016.  more...
     

    Berlin drills for the heating transition

    The research project ATES is to clarify whether or not Berlin's geological subsurface aquifers are suitable for the seasonal storage of heat and cold. These aquifers could store excess heat from summer up until the heating season starts, and then supply entire neighbourhoods. At the end of February 2016, the GFZ German Research Centre for Geosciences  in Potsdam started drilling an exploration well on the campus of TU Berlin. The well has now reached its final depth of 560 metres. In a BINE interview, Professor Ernst Huenges speaks about goals and prospects.  more...

    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...

    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...
     

    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...
     

    Modelling power supply for 2050

    By 2050, the goal is for renewable energy sources to generate at least 80 per cent of power. In order to then still guarantee reliable supply at affordable prices, the entire energy system must be adapted and converted in a step-by-step process. The increasing share of fluctuating energy sources requires a flexible system that can react quickly. A research project demonstrates the degree of grid expansion, storage and new regulation opportunities that are technically required for this purpose, and which make economic sense.  more...
