    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...

    Efficiently capturing carbon dioxide with spray scrubbers

    Spray scrubbers have been successfully used in power plants for years for desulphurising flue gas. Now it is intended that they should scrub another material – namely climate-harming carbon dioxide (CO2). Until now a hurdle preventing large-scale CO2 capturing has been the high investment costs for the plant technology and the considerable amount of energy required for the operation. The University of Stuttgart is therefore working with partners to improve this process.  more...

    Storing wind energy underground

    Pumped storage power plants have been in use for over a hundred years to balance fluctuating electricity loads and to cover peak loads. The energy transition creates additional storage demand with its fluctuating feed-in of wind and solar power into the grid. New sites, however, are scarce. Whether the large differences in the tunnel heights of abandoned mines are usable or not is currently being investigated by an interdisciplinary team of researchers on the basis of two viable locations.  more...
     

    Precisely measuring how wind turbines affect the grid

    Every wind turbine that is connected to the grid affects the grid quality. Until now, operators have not known the precise extent to which they do this and instead rely on estimations. In order to make better use of capacities and prevent disruptions, scientists at Helmut Schmidt University in Hamburg have therefore designed a measuring device that determines the effect of wind turbines on the medium-voltage grid. It is planned to produce a measuring device for high-voltage lines by 2016.  more...
     

    Storing solar energy with new materials

    The interdisciplinary NEOTHERM junior research group at Otto von Guericke University in Magdeburg is developing new materials for storing thermal energy. Using new composite materials, the scientists at the Faculty of Process and Systems Engineering (FVST) want to recover and store unused solar thermal energy and waste heat from industry. This energy can be used, for example, for heating domestic hot water or for space heating.  more...
