    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...

    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...
     

    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...
     

    Adjusting operation of biogas plants to power requirements

    Compensating supply fluctuations will prove vital in future power grids utilising high proportions of wind and solar energy. The demand driven generation of electricity from biogas can make a viable contribution in this regard. Researchers are developing new systems and software for biogas plants, integral in facilitating such flexible operational characteristics. This involves the precision monitoring and regulation of biogas production and conversion into electricity.  more...

    Which heat sources are optimal for heat pumps?

    The number of buildings heated by heat pumps continues to rise. In recent years, air-water heat pumps have been the dominant force in this regard. More energy efficient alternatives exist, however, to outside air as a heat source. Examples include geothermal energy, ground water, exhaust air and solar thermal energy. The variety of potential heat sources and of heat exchangers tapping these presents an incredible challenge for planners. Validated concepts, objective decisionmaking guidance and analyses are consequently called for. This endeavour is supported by two research groups.  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...
     

    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...
     

    Developing multifunctional façade elements

    As the outermost layer of the building envelope, the façade performs numerous functions. They are to be intelligently combined to create a system that permits the application of cost-effective, multifunctional façade systems. To do this, scientists are developing a façade element with integrated organic photovoltaics, textile sun protection, a sustainable insulating material and the sensors necessary for control. The next step is to test the elements on the south façade of a multi-storey residential building.  more...
     

    Heat supply – solar-active and grid-connected

    Since autumn 2016, a new passive house residential neighbourhood has been under construction at the science and technology site Berlin Adlershof. It is connected to the return feed of an existing district heating network and feeds in the solar heat generated inside the district. The project is the subject of extensive research.  more...
