    Research on large-scale battery storage system

    The modular, large-scale M5BAT battery storage system recently began operating in Aachen, Germany. With a 5 MW output and a storage capacity of 5 megawatt-hours, it is the largest battery storage system currently being researched. Together with industrial partners, scientists at RWTH Aachen are testing the interaction of five different battery types and are developing business models for decentralised storage systems in actual grid operation.  more...
     

    Networked micro-CHP plant in field test

    Small engine-based cogeneration plants and fuel cells can be combined together and operated as a network. Such a regional virtual power plant (RVPP) is currently being tested by researchers at the TU Dresden and EWE AG in the Oldenburg area. They are developing control and regulation concepts for operating in networked systems until the end of 2017.  more...
     

    Video inspection tool brings light into the darkness

    Scientists in Karlsruhe are developing a camera inspection system for deep geothermal drilling holes. The device must be able to withstand strong pressure and high temperatures. This presents a particular challenge for the electronic components. A first draft design for the system has now been completed.  more...

    Rotor blades with elastic front edges

    During the course of their operation, countless raindrops land on the leading edge of the rotor blades used on wind turbines. Despite the special coatings and films applied to these edges, this damages the surface. Over time, this causes erosion to the leading edge of the blades. A research project is therefore testing a new approach: in future, elastic leading blade edges could solve the problem.  more...

    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...
     

    Ceramic cube reduces gas losses

    Scientists have developed a new ceramic heat exchanger for industrial furnaces. This can transmit considerably more exhaust heat to the combustion media than the metal recuperators currently used in high-temperature furnaces in the process industry. The new ceramic recuperator thereby decreases the exhaust gas losses to less than 25 per cent.  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...

    New lighting strategies for streets, footpaths and squares

    LED is the future of street lighting. The LED Walkway on the grounds of Berlin’s Technology Museum, which opened in March 2015, demonstrates potential applications. The lighting technology developed allows the lighting level and light conditions to be adapted to external factors such as weather conditions and traffic volume. Spaces can now be set to a defined brightness with minimum stray light. The “StEffi Street Lighting” research project, launched in May, aims to develop and evaluate concepts for space-specific lighting and increase the potential savings with LED technology.  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...
