    Sorting green waste and using it for producing energy

    In addition to the “Biotonne”, the organic waste bin used by German households for mainly disposing of domestic vegetable waste, the separate collection of coarse woody materials from garden and park waste could provide a significant amount of fuel for thermal utilisation. Scientists have investigated the potential provided by biomass that is better suited for combustion in CHP plants instead of composting.  more...
     

    Researchers investigate market design and operations management

    In the REGEES research project, a consortium from research and industry has developed optimal operating and control strategies for a reliable electrical energy supply in Germany. The aim is to fully integrate the feed-in from renewable energies created by 2030.  more...

    Hydrogen for the urban energy transition

    A new, almost climate-neutral urban district is being built on the site of a former freight yard in Esslingen. Over a period of five years, scientists in the planned Neue Weststadt district are experimenting with an innovative energy supply concept with which electricity surpluses from intermittent renewable energies will be converted into hydrogen, stored and, if necessary, returned to the grid. The district will also serve as a real-world laboratory for the system-supportive coupling of the heating, cooling, electricity and mobility sectors.  more...

    National 5G Energy Hub project launched

    Last week, TU Dresden officially launched the long-term National 5G Energy Hub research project. This is aimed at making the future 5G mobile standard usable for applications in energy technology. Project partners are TU Dresden in cooperation with RWTH Aachen, Deutsche Telekom and Ericsson. In addition, the associated partners Techem, VDZ, E.ON and the city of Dresden are also involved.  more...
     

    CIGS thin-film modules beautify house walls

    In order to achieve the goal of meeting Germany's energy demand almost completely with renewables by 2050, it is planned that facades and partially shaded surfaces should also be used for generating electricity by photovoltaic means. The modules that can be used for building-integrated photovoltaics (BIPV) have to meet considerable requirements in terms of their appearance, performance and costs. Experts have summarised this need for action in their recommendations for the German federal government's 7th Energy Research Programme.  more...
     

    Photovoltaic elements for facades and flexible roofs

    Modern building facades can do more than provide insulation and outer envelopes for buildings. New photovoltaic modules give designers considerable scope when designing the colour of facade surfaces. Unlike standard solutions, such energy facades make a considerable contribution to improving the energy balance of buildings. Standard silicon, thin-film and organic PV elements can be used.  more...
     

    Solar water heater for ceramic granules

    The innovative CentRec radiation receiver has passed its first practical test at very high temperatures in the DLR’s solar tower in Jülich. The receiver uses ceramic particles as a heat storage medium. These are inexpensive, enable very high temperatures and can be handled with relatively little effort. The practical test at very high temperatures is an important step on the way to marketing this receiver technology.  more...

    Test methods for practical key system figures relating to energy efficiency

    Measurements on real heat generator plants show that efficiency parameters as determined by calculation sometimes deviate considerably from the values registered by measurement technology. This is especially true for heat pumps and micro CHP plants. The annual performance factor is decisive in terms of their economic success.  more...
     

    Superconducting generator on the test stand

    Compact design, low tower head mass and good transportability: The high-temperature superconducting generator, which was developed in the EcoSwing research project, is to be used in the next generation of multi-megawatt turbines. The practical feasibility of the concept is being verified in a test campaign on Fraunhofer IWES’ nacelle test rig and in a follow-up field test in a two-blade system in Denmark.  more...
     

    Network-neutral energy-plus district Geretsried

    Researchers at Munich University of Applied Sciences and TU Dresden have developed an innovative energy concept for an energy-plus district, which is to be implemented in the “Neue Mitte” of Geretsried (Bavaria) by the end of 2019. The concept combines the utilisation of different energy technologies with the goal of electrical network neutrality, i.e. maximising own coverage of electricity requirements and own use of the generated electricity.  more...
