    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...

    Objective planning of the grid expansion

    The ideal course of a power route depends on a number of factors. Scientists at the Technical University of Dortmund have joined forces with the grid operator Amprion to model a weighting function which systematically reproduces the relevant criteria. A computer-aided planning tool shall enable planners to make an objective assessment of various route layouts, visualise different alternatives and swiftly develop suitable compromises.  more...
     

    Science and business park grows efficiently

    If the current trend is extrapolated, the energy requirement of the Berlin-Adlershof science and business park will double by 2020 as a result of relocations and an increase in density. The implementation of a new energy concept is to help the site achieve 30 % savings in primary energy. Central to the concept is the energy-efficient improvement and cross-linking of buildings, systems and processes, the use of waste heat, efficient electricity and heat supply and the introduction of a technical and non-technical energy management system.  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...
     

    German Federal Environment Agency moves into zero-energy building

    The staff at the Federal Environment Agency’s research facilities in the Berlin district of Marienfelde can now test the German government’s first zero-energy building during their daily work. The energy supply is based on the exclusive use of renewable energies: a photovoltaic system produces electricity and a heat pump generates the necessary heating and cooling energy. The building is intended to generate just as much energy as it requires within one year.  more...

    An island becomes power-independent

    The North Frisian island of Pellworm has been a showcase for energy research since the early 1980s. The largest solar farm in Europe was installed there in 1983. In 1989, wind turbines were added to create Europe’s largest hybrid power plant. Now, the island is due to become power-independent, with an intelligent electricity grid with large-scale storage facilities and a large number of home storage systems.  more...
