    Calculating and comparing refurbishment costs

    Maintaining and refurbishing municipal properties to improve their energy efficiency costs money that in many cases is lacking. A new software program now makes it possible to calculate different refurbishment scenarios for existing municipal buildings and to compare them in detail. This helps to strategically plan the investment in cities and local communities.  more...

    Testing rotor blades cost-effectively

    The longer the rotor blades used on wind turbines, the greater the forces acting on them. The requirements for the components rise – and with them the demands made on the testing methods. On the one hand it is important to construct the blades as durably as possible. On the other hand, however, they also need to be manufactured so that they are as cost-effective and as light as possible. If a compromise is found, this still needs to be checked in a verifiable way: on the computer and in practice.  more...
     

    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...

    SpeedColl: Allowing collectors to age more quickly

    Whether in maritime, arid or alpine regions, solar collectors must perform flawlessly for years. But to what extent do high UV radiation, salty and humid air take their toll on the collectors? In order to find out, researchers at Fraunhofer ISE and Stuttgart University exposed solar collectors to the wind and weather at six locations. The result: The collectors and the components are more durable than previously thought. However, that makes it even more difficult to make comparisons.  more...

    Doubling the power density with metal fibres

    Zeolite can adsorb significant amounts of water vapour, thereby releasing latent heat. This property is used among others in gas adsorption heat pumps. Scientists have found a way to increase the heat transfer area, thereby increasing the power density of the heat pump module. An initial sorption module with an innovative zeolite coating for the heat exchanger is now available.  more...

    Once coated, everything runs smoothly

    The wear and energy consumption of machinery increase dramatically if the machines are not optimally lubricated. In many cases, however, ideal lubrication is impossible, for example, in free-running motorcycle chains or agricultural machinery. To meet these operating conditions, researchers are therefore developing new coatings, and lubricants adapted to them, as part of the CHEOPS3 project. The twelve project partners from industry and science want to achieve long-term protection against wear, even with minimal lubrication and dry friction, so as to increase the efficiency of machines.  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...

    Guidelines for energy-efficient data centres

    In Germany alone, data centres annually consume around 10,000 GWh of electrical energy – with an upward trend worldwide. In the RenewIT European research project, scientists from Spain, the Netherlands, Italy, the UK and Germany are investigating how data centres can be almost completely powered by renewable energy. The preliminary results are now available. BINE Information Service spoke with Dr Thorsten Urbaneck, private lecturer at Chemnitz University of Technology, and the project manager of the German part of the collaboration.  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...
     

    Researching the natural seismicity

    The Upper Rhine Graben (Rhine Rift Valley) has geothermally usable hot water resources at an attainable depth. This geological feature is caused by the fact that the deep rock strata has remained in motion to this day. This repeatedly causes slight natural earthquakes in the region. In rare cases, however, human activities, such as the construction and operation of geothermal plants, can also trigger shocks. This effect is called induced seismicity. Prior to constructing a geothermal plant in Groß-Gerau, researchers have therefore been measuring the natural seismicity in the region using a dense monitoring network.  more...
