    Prospects for pumped storage power plants

    Pumped storage power plants make an important contribution to securing energy supplies and help to integrate renewable energies into the electricity grid in a profitable manner. However, it is precisely the grid feed-in of wind and solar power that is threatening the current business model for the plants. A study is therefore investigating how their economic viability and the investment environment can be improved through cooperation between Germany, Austria and Switzerland (the DACH countries).  more...
     

    Flexible deployment of heat storage systems

    Those retrofitting heat storage systems in buildings often come up against their limits. Large-volume storage tanks often do not pass through standard doors. Together with Consolar, which manufactures solar thermal systems, scientists at the Institute for Thermodynamics and Thermal Engineering at the University of Stuttgart are therefore developing a storage system that consists of several modules and can be assembled on site. The modular storage system will be installed in an apartment building and tested in practice in autumn.  more...
     

    Research funding for the energy turnaround increasing

    Energy research contributes towards the development of the processes and technologies necessary for achieving the goals of the energy turnaround. The German government has been continuously increasing funding for energy research since 2006. In 2013 alone, it spent 100 million euros more on this than in the prior year. This reinforced above all the research areas of energy efficiency and renewable energy sources. It provided just under 300 million euros for each of these subjects.  more...
     

    Stabilising the grid with wind power

    In future it is intended that photovoltaic systems and wind farms contribute more to the stability of the electricity grid. They could then replace some of the fossil fuel capacities that until now have had to be used for the sole purpose of balancing out frequency variations. In a study, methods have been developed that can be used for intermittent renewable energies when bidding to supply control reserve as part of regular tendering periods.  more...

    Application prospects for hydrogen storage systems

    Can large-scale hydrogen storage systems help pave the way for renewable energy? Scientists from several research institutes investigated the technical and economic requirements for this in the PlanDelyKaD research project. The research focused on hydrogen electrolysis and gas storage in salt caverns. The study also revealed the method’s potential on the market.  more...
     

    Compact grid nodes for low-loss electricity transmission

    The development of compact switching points for DC transmission solves a problem caused by the grid expansion: the grid nodes and feed-in systems are becoming smaller and can thus be installed more conveniently in urban areas and on platforms for offshore wind farms. Siemens’ development manager Denis Imamovic is today presenting the latest results of the research project at the Berliner Energietage conference.  more...
     

    “Secure provision of data centres with renewable energies”

    The RenewIT project is researching how data centres can make greater use of renewable energies. That is an important goal for project partner Thorsten Urbaneck, who is a private lecturer at Chemnitz University of Technology. This is because it is estimated that data centres consume two per cent of the electricity used in Europe – and the trend is increasing.  more...
     

    Storing summer heat until winter

    In the SolSpaces project, researchers from the Institute for Thermodynamics and Thermal Engineering at the University of Stuttgart are developing a new heating concept for compact residential buildings. This includes a collector system with a thermochemical storage system that can store the solar thermal energy from summer until winter. The scientific monitoring has begun.  more...

    The use of electric vehicles in urban delivery traffic

    Around one third of the traffic in cities consists of trade contractors and suppliers. Until now, this so-called commercial traffic has mostly relied on diesel power. Electric vehicles, however, could provide an ecologically, technically and economically viable alternative, since the typical operations and routes used by care services, parcel couriers and contractors match the short ranges provided by electric vehicles. A research group led by the Technische Universität Berlin is now investigating how electric vehicles could be sensibly used in the urban commercial traffic.  more...

    Superconductor begins test operation

    Developers from science and industry are jointly investigating the technical, economic and ecological aspects concerned with superconductor technology in electricity grids. As part of the AmpaCity project in Essen, a two-year test operation is scheduled to be launched this spring with a one-kilometre superconductor test route. This test is designed to show that superconductor technology could provide a future alternative to conventional high voltage technology in cities.  more...
