    AmpaCity receives innovation award

    Since the spring of 2014, a superconducting cable helps to ensure that the lights stay on in the centre of Essen. It transmits up to 40 megawatts of electricity – almost without loss. With AmpaCity, researchers from science and the electricity industry are demonstrating how high voltage lines and transformer substations could be eliminated in urban areas. On 20 January 2016, the project, which is funded by the German Federal Ministry for Economic Affairs and Energy, was conferred the German Innovation Prize for Climate and the Environment.  more...
     

    Neckarpark Stuttgart: Heat from waste water

    Sewage stinks and is filthy – but it is suitable for supplying heating and cooling to buildings. In Stuttgart’s new Neckarpark urban district, the energy in the municipal waste water is extracted by means of a trough heat exchanger in the sewage channel and utilised via a low-temperature local heating network. This provides the basis of the energy concept for the new district, which is being created with highly energy-efficient buildings on the brownfield site belonging to the former Bad Cannstatt railway freight depot.  more...
     

    Lime storage systems: Cheap, efficient and sustainable

    At the German Aerospace Centre (DLR), researchers are using lime as a storage medium in a specially developed heat storage system. This enables heat to be stored in the form of a reversible reaction. Such storage systems can help large amounts of energy to be used more efficiently in industrial processes and households. The new plant has now been put into operation.  more...

    Future heating supply designed

    Over the past thirty years, the population of Duisburg has fallen by more than a fifth, and the heating requirement has also reduced. A team of experts has investigated how the municipal utility company can adapt the heating supply in accordance with these developments by 2050. A main recommendation: The interconnection of two district heating networks would increase the primary energy efficiency and cut costs, mainly because industrial waste heat could be better utilised.

    Heating buildings via their exterior walls

    Surface heating systems facilitate the integration of renewable energy sources and reduce energy costs. However, since the retrofitting of underfloor heating is very expensive, thermally activated walls provide an option in existing buildings. For the first time scientists at Saarland University are testing the use of capillary tube mats in exterior wall heating.  more...

    Electricity grid with strong genes

    The electricity grid is both dynamic and sluggish at the same time. On the one hand, it distributes electricity with rapidly fluctuating loads. On the other hand it takes a long time before constructional changes can be planned and carried out, which is due to both technical and social reasons. This makes it important to assess future scenarios with simulations. Scientists at RWTH Aachen are achieving this with their GENESYS software program.  more...

    More energy for electric cars

    In the alpha Laion research project, the alliance partners are aiming to develop improved batteries for electric cars. These are intended to provide a high energy density and cycle stability, which will increase the range of the vehicles and ensure a long service life. The researchers developed and tested new materials and compositions for the anode, cathode and electrolyte. The results of the project have now been presented.  more...

    Efficiently using district heat

    In future, it is intended that heating and domestic hot water systems in district heating networks should be increasingly capable of functioning with environmental heat at lower temperatures. However, at the moment the cooling potential is not yet being satisfactorily utilised. This is generally resulting in return temperatures and volume flow rates that are too high. This provides the starting point for the LowEx Systems project.  more...
     

    Energy centre supplies Giessen University Hospital

    Giessen’s municipal utility company and University Hospital have jointly constructed the first energy centre to be integrated into a local heating and cooling network. The newly developed combined cooling, heating and power system ensures an uninterrupted supply to the hospital. It saves 21.7 % of the primary energy and 33.6 % of the CO2 emissions.  more...

    Securely controlling dynamic electricity grids

    The construction of power plants that generate electricity from the wind and sun continues apace. In particular at high sea, but also in rural areas, there is still considerable development potential during the next few years amounting to several gigawatts. The load centres, however, are situated in the metropolitan areas in the middle and south of the country. It is therefore important to integrate the locally created surplus capacities in an intelligent manner.  more...
