    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...

    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...

    Metal foam – a material for heat engineering

    Metal foams are increasingly developing into materials with diverse uses. While metal foams with closed pores have already become established as rigid and strong lightweight materials, the open-cell variant is suitable for thermal engineering applications. Until now, the material has been rarely used in heat exchangers or coolers because the production is expensive and its application little tested. Researchers at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Dresden now want to change 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...

    Fuel cell generates electricity and heat for homes

    Highly efficient, low-emission and quiet: as small-scale combined-heat-and-power stations, new fuel cell heating units produce heat energy and electrical energy with an efficiency of over 90 per cent. They have proven themselves in extensive tests in single and two-family homes, and their operation and design have been improved incrementally. The first units are now on the market. They run on natural gas, and on hydrogen and methane produced using renewable energy or biomass. Decentralised fuel cells can generate demand-oriented electricity, and they can be used in a grid-friendly or grid-independent way.  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...
