    Heat pipes de-ice railway points

    Geothermal heating ensures that railway points also remain working when there is ice and snow. Once installed, they work independently using only geothermal energy and without any additional energy being supplied. After many years of research and testing in pilot rigs, the system has now been approved by the German Federal Railway Authority.  more...
     

    Sustainable use of deep geothermal energy

    The alpine foreland is experiencing a geothermal energy boom. The region boasts a vast quantity of deep geothermal water. In the Greater Munich area alone, 15 geothermal heat stations and power plants are currently either in operation or under construction. Geoscientists led by the Leibniz Institute for Applied Geophysics (LIAG) have studied the geological and hydraulic conditions of the region and developed a simulation model. This model can now be used to better predict the interplay between power plants, long-term operation and exploration risks of new plans.  more...
     

    Thermal heat from pit water

    The coal mining company RAG annually pumps over 100 million cubic metres of water to the surface from a depth of up to 1,000 m to secure the stability of the ground and the safety of drinking water in former mining regions. For one year now, the municipal utility of Bochum has been heating several public buildings with that pit water. The pilot project demonstrates how to use old mines for an eco-friendly heat supply of surrounding buildings.  more...

    Metro tunnels enable geothermal air-conditioning

    When constructing new underground metro lines it is possible to integrate geothermal plants with few additional costs. That provides an excellent opportunity to use this renewable energy source in cities with densely built underground infrastructures. A test plant is in operation on Metro Line 6 at Stuttgart’s Fasanenhof underground station. Scientists at the University of Stuttgart are investigating the effects that the geothermal activation of the tunnel is having on the subsurface.  more...

    The supermarket of the future saves energy

    The energy savings division at the discount store Aldi Süd in Rastatt should in the future only need two-thirds of the primary energy usually required for refrigeration, heating, ventilation, air conditioning and lighting. A compressor pack with carbon dioxide as a coolant which has been developed in-house, and which is coupled to borehole heat exchangers, not only cools food, but also provides temperature control for indoor areas.  In the third year of operation, the amount of energy consumed is coming close to the ambitious target levels.  more...
     

    Ismaning banking on geothermal energy

    The Bavarian municipality of Ismaning is generating increasingly more electricity and heat from local energy sources. During the next few days, pump and injection tests will begin on the new geothermal plant that will continue for several months. At a depth of around 2000 metres, the two wells are extracting more hot water than was originally assumed. The trial operation of the geothermal heat supply can therefore begin.  more...
     

    Research becoming increasingly important

    At the Annual Conference of the Renewable Energy Research Association (FVEE) on 16 and 17 October 2012, scientists and industrial representatives presented innovations along with new strategies for their market introduction. In his opening speech, Federal Environment Minister Peter Altmaier emphasised that greater importance should be given to research and development in regard to the era of energy revolution.  more...
     

    Forty per cent of local heating market achieved

    The Unterhaching geothermal plant, one of the most successful geothermal projects in Germany, is celebrating its 10th anniversary on 20 October with an Open Day. The plant feeds heat into a district heating network and the remaining heat is used to generate electricity. For this purpose a special power plant process is utilised, the Kalina process. In the BINE Interview, Managing Director Wolfgang Geisinger talks about his decade of experience with the plant, technology and components as well as about the local heating market.  more...
     

    Using solar roofs twice over

    Instead of screwing various module and collector types for solar power and solar heat on the roof, an obvious idea would be to use a hybrid collector that can do both and which creates a uniform appearance. In addition to generating photovoltaic electricity, which only utilises 15-20 % of the incident solar radiation, a so-called PVT collector can use the remaining radiation energy for generating heat. Researchers are working on optimising the output and production of these systems.  more...
     

    Investigation of crystalline rock layers for geothermal energy

    In Germany, most geothermal plants are currently located in the Bavarian Prealps and in the Upper Rhine Graben. These predominately use the natural heat from the sedimentary aquifers in these basins. However, the larger geological heat deposits are found in crystalline rock layers. Together with its partners, the Leibniz Institute for Applied Geophysics (LIAG) has therefore started a 12-week geophysical measurement campaign in a 100-km² area within the Erzgebirge mountains. This is intended to determine whether geothermal energy generation is possible there.  more...
