    "We have to increase our efforts!"

    The first ENERGIEWENDEBAUEN conference took place in Berlin from 30 - 31 January, 2017. Some 350 participants from research, academia, architecture and planning offices, politics, energy suppliers, cities and municipalities as well as the real estate industry discussed how the energy supply of buildings and districts could be made future-proof. The aim of the German federal government is to create a climate-neutral building stock by 2050. This will not be easy to achieve.  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...
     

    New wind energy test field in southern Germany

    Because of the pronounced terrain structures, wind farms in low mountain ranges have to cope with more turbulent wind conditions than in lowland areas. These meteorological conditions mean that development and maintenance costs have been higher up to now in landlocked mountainous areas, while precise profit forecasts are more difficult. A new wind energy test field belonging to the southern German research group WindForS now aims to close the gaps in meteorological knowledge and optimise the wind turbine engineering.  more...

    Networked factory stabilises the grid

    The factory of the future is flexible and networks the energy flows between machinery and buildings. The so-called Phi Factory is not only very energy-efficient, it also helps stabilise the electrical supply grid. The new model factory relies on a high share of renewable energy and helps smooth out electricity supply fluctuations.  more...
     

    Impact of defects can be calculated

    Large wind turbine components are made of cast iron with spheroidal graphite. During their production, however, chemical reactions can cause defects. These casting defects are called dross and their impact on component lifetime has, to date, only been evaluated using assumed material characteristics. There is a measure of uncertainty involved in providing evidence of their occurance. New non-destructive test methods should now be able to evaluate dross more reliably.  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...
     

    It's turbulent offshore

    In offshore wind farms, the front turbines receive the most wind. They cause kilometre-long vortexes with slower wind and increased turbulence, which affects the downstream wind turbines. Previous methods that mimic such wakes are inaccurate or require considerable computation. In order to better understand these wake effects, scientists have therefore developed a new model and software to help optimise farms.  more...
     

    Solar thermal and photovoltaic power plants in comparison

    How will the market for photovoltaic and solar thermal power plants develop in the coming decades? Which technology is economically more efficient? And what opportunities are offered by combined power plant systems in sunny regions? A study carried out by the German Aerospace Centre (DLR) has investigated the development of these power plants until 2030.  more...
