    Flexible turbomachines stabilise the power grid

    In future, conventional power plants will need to become more flexible in order to compensate for the fluctuating power generation by renewables. This requires modified gas and steam turbines. These will have to work more frequently under partial load, with more start-up and shut-down cycles and function with changing fuels. AG Turbo has compiled the research and development objectives for these new framework conditions in the ECOFLEX-turbo programme.  more...

    Servers heat office buildings

    The Züblin construction group set high standards for the extension of their headquarters: in terms of construction, energy efficiency and sustainability. In operation, the energy consumed for heating and cooling is below the calculated values. The high-performance data processing centre housed in the building provides enough thermal energy to heat the building. The thermal comfort leads to a high level of satisfaction of the occupants. Most of the energy – far more than planned – is consumed by artificial light.  more...
     

    Extracting fumes in rolling mills

    Aluminium foils and sheets pass through a cold roll stand during the last processing step of their production. Rolling oils are sprayed on to cool and lubricate the rolls. Some of these kerosene-like hydrocarbons evaporate and vaporise in the ambient air. Large extraction hoods above the roll stand collect the contaminated air and feed it to a recycling plant.  more...

    Syngas from biocoals

    Organic waste, thinning wood, straw and landscape management waste products are still little used for generating energy. This is because such biogenic residues have poor combustion properties owing to their inhomogeneous composition or high moisture contents. However, researchers from the Technical University of Munich and SunCoal Industries are now producing biocoal from such material using a new process.  more...

    Large storage tank developed for small spaces

    To heat an apartment building highly efficiently, using a solar power system or combined heat and power plant for example, you need large thermal storage tanks. They often do not fit through standard door openings in existing buildings. Scientists developed a compact storage tank consisting of multiple modules, which is not assembled fully until it reaches the boiler room. Heat losses are lower than with standard cascade models. Individual tanks no longer have to be connected.  more...
     

    Cheaper production of solar cells

    There is intense competition in the market for photovoltaic systems. With constantly new innovations, the manufacturers are reducing their production costs and are increasing the efficiency of the cells and modules. For this purpose they are improving the production processes along the chain from silicon to the module. Companies and research facilities are working together to produce high-quality silicon crystals and wafers that save as much material as possible. They are also improving the material quality using an innovative solidification process for quasi-monocrystalline silicon. And with a new separation process they are producing more wafers from the same amount of silicon.  more...

    Superconductors for the medium-voltage grid

    Scientists are testing the longest high-temperature superconducting cable in the world under real conditions in Essen. One kilometre long, it connects two substations in the inner city. It replaces a conventional 110 kV line and renders one substation in the inner city obsolete. After two years of testing, it has passed the field test. It could be a blueprint for the future power supply system in urban areas.  more...
     

    Communication concept for deep geothermal energy

    Technical innovations can only be successful if they are supported by the public. Plants for utilising renewable energies are also dependent on this backing. Early and comprehensive communication with the public is therefore indispensable. For deep geothermal energy, scientists have analysed public perceptions and have developed a communication concept. It offers operators and authorities a wealth of ideas and support for active and transparent public relations.  more...

    The smarter blade gives in

    Onshore and offshore, rotor blades need to be able to withstand rapidly changing wind directions and variable wind intensities. But how can rotor blades be better equipped for such situations than previously? Researchers have designed so-called smart blades that can adapt to changing wind conditions passively or with active components – and at the same time maximise the energy yield of the wind turbine.  more...

    Reducing energy use from waste treatment

    Residual household waste lands in the grey waste container. It is either thermally exploited in a waste incineration plant, or it is taken to a plant for mechanicalbiological waste treatment. Here, the waste is sorted: Energy-rich parts are used for energy, while metals are recycled. The residues are treated in rotting boxes before disposal on landfills. The exhaust air from the process has to be purified. This takes up almost two-thirds of the energy consumption of waste treatment plants. Researchers, in collaboration with their project partners, have developed a more efficient method.  more...
