    Energy research on course to delivering the energy transition

    The German federal government recently published the National Action Plan on Energy Efficiency. The concept is specifically aimed at winning over all actors in society in achieving greater energy efficiency. A few days later, the German Federal Ministry for Economic Affairs and Energy announced its research funding for the German federal government’s 6th Energy Research Programme. In the BINE interview, Dr Rodoula Tryfonidou from the responsible department in the German Federal Ministry for Economic Affairs and Energy talks about the contribution made by energy research in bringing about the Energiewende – Germany’s energy transition.  more...

    Heating system keeps rotor blades ice-free

    In cold climate zones, the wind is particularly strong meaning best conditions for a wind turbine. However, in the cold temperatures there is the danger of ice that can freeze onto rotor blades. This can lead to imbalances, impairment of the rotor blade’s aerodynamics and a drop in the efficiency of the turbine. The so-called carbon-nanotube coating offers a solution.  more...
     

    Fast-track testing of nacelles

    In Bremerhaven, a test rig is being developed that can test complete wind turbine nacelles in the multi-megawatt class. Unprecedented: a load transmission system mechanically simulates the wind loads occurring in the field. The researchers are investigating the electrical components using a simulated electricity grid. Laboratory tests are also providing information on how wind turbine concepts can be improved. With these properties, the test rig has the world’s most powerful grid simulation system.  more...

    New coating protects masts from corrosion

    Submerged sections of offshore plants provide the ideal habitat for colonisation by mussels and microorganisms. This can lead to biologically-induced corrosion and premature wear. To inhibit this, new coatings and surface structures are being developed by 14 partners from science and industry in the Foulprotect project. These are intended to protect plant foundations against "biofouling".  more...
     

    Producing rotor blades more quickly

    Scientists at the University of Bremen have developed a new automated process for the production of rotor blades together with partners from industry. A textile product is first cut to size mechanically, stacked, shaped in accordance with the subsequent blade design and then placed in the negative mould. This is followed by the injection of the resin. The process is intended to shorten production time and improve quality.  more...
     

    Research funding for the energy turnaround increasing

    Energy research contributes towards the development of the processes and technologies necessary for achieving the goals of the energy turnaround. The German government has been continuously increasing funding for energy research since 2006. In 2013 alone, it spent 100 million euros more on this than in the prior year. This reinforced above all the research areas of energy efficiency and renewable energy sources. It provided just under 300 million euros for each of these subjects.  more...

    Researching in the global network

    International research collaborations are becoming increasingly important. Germany is involved in a variety of ways in international energy research. An important pillar in this regard is its involvement in the International Energy Agency (IEA). Germany is a founding member of this organisation. An IEA field of activity particularly relevant to energy research is its energy technology network.  more...
     

    Stabilising the grid with wind power

    In future it is intended that photovoltaic systems and wind farms contribute more to the stability of the electricity grid. They could then replace some of the fossil fuel capacities that until now have had to be used for the sole purpose of balancing out frequency variations. In a study, methods have been developed that can be used for intermittent renewable energies when bidding to supply control reserve as part of regular tendering periods.  more...

    Database shows output from renewables

    The sources of renewable energy –sun, wind, water and biomass – account for a large share of the electricity production in Germany. At the beginning of July 2014, solar energy covered the entire peak load. This is shown in the new online “Energy Charts” database at the Fraunhofer Institute for Solar Energy Systems ISE.  more...
     

    “Wind energy has excellent prospects inland”

    One of the highest wind measurement masts in Europe has been standing on top of a wooded hill near Kassel since 2011. The mast is being used to investigate the wind layers between 100 and 200 metres in height and the influence of forest cover and terrain inclinations on the wind profile and generation of turbulence. The measured values, which are obtained using conventional sensors on the mast, are also used to validate and further develop laser-based LiDAR methods. In the interview, Paul Kühn, Group Manager for Onshore Site Assessment at the Fraunhofer Institute for Wind Energy and Energy System Technology IWES, talks about the project’s initial results and future prospects.  more...
