    Solar cell uses front and back

    So-called bifacial solar cells can convert incident light into electrical current both on their fronts and backs. They are up to 30 per cent more powerful than conventional monofacial cells that use only their fronts. The hitherto very complicated production of such double-sided solar cells has now been made simpler and less expensive by means of a newly developed doping process.  more...

    Keeping the oil in the engine

    Each time the fuel-air mixture is ignited in petroland diesel engines a small portion of the gases flows from the combustion chamber into the crankcase as leakage current. For the engines to function optimally, it is necessary to dissipate these so-called blow-by gases and separate the engine oil droplets contained within them. This reduces the pollutant emissions and oil consumption of the engines. For modern, higher-compression engines, researchers have developed new and effective separation systems that undercut the more stringent emission limits for oil mist.  more...
     

    New low-emission marine engines

    The operation of ships causes considerable pollutant emissions. Future ship propulsion systems must therefore be more environmentally friendly. One possible way is to operate engines with natural gas rather than diesel. They have lower emissions when compared with current diesel engines without exhaust after-treatment. Researchers are developing and testing components and control instruments for this economical new generation of engines. They are aiming to reduce the engines' CO2 emissions and halve them in future.  more...

    40 years of energy research

    Last week, on 2nd May 2017, the German Federal Minister for Economic Affairs, Brigitte Zypries, opened the celebration for the anniversary of “40 years of energy research programmes in the German Federal Government” in the historic conference rooms of the German Federal Ministry for Economic Affairs and Energy in Berlin. She emphasised that research and development are important components in the large modernisation and investment project for energy transformation in Germany.

    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...
     

    The future of power plants

    The "Flexible Energy Conversion" research network was founded in Berlin at the end of February 2017. Here, researchers and developers from the conventional power plant technology and solar thermal power plant fields will jointly develop future strategies. The goals: To increase the flexibility of large-scale power plants, develop new large-scale storage systems, extensively research the use of hydrogen in power plant processes and in particular optimise the economic efficiency of solar power plants.  more...
     

    The sun shines with the click of a mouse

    Synlight is the name of the world's largest artificial sun, which is situated in Jülich near Aachen. Its bundled light is 10,000 times stronger than the sun. With this energy, researchers want to test solar thermal components in order to produce hydrogen directly – without having to use electrolysis. Last week, the research facility was officially inaugurated.  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...

    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...
