    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...

    Steel pistons for more efficient diesel engines

    With a new cooling concept, an automotive industry supplier is expanding the range of applications for steel pistons in diesel engines. The Stuttgart-based company is testing a liquid alloy comprising sodium and potassium, which dissipates heat from the particularly thermally loaded piston head. This innovative steel piston concept is designed to enable even further increases in the specific power of car diesel engines. In the case of long-running engines for industrial applications and commercial vehicles, the component and engine oil load is significantly reduced while the expected service life and oil change intervals are prolonged.  more...
     

    The hotline in the grid

    The electricity grid that has been used for decades reaches its limits when transporting increasing amounts of electricity over long distances. There are already limiting bottlenecks. One way to integrate more wind and solar power into the grid is provided by overhead lines with a higher maximum temperature. These can transport more electricity, enabling grid congestion to be avoided. One problem, though, is that metals expand more at high temperatures. As a result the line lengthens and sags more. However, special high-temperature conductors can provide a remedy here.  more...
     

    Measuring wind potential in low mountain ranges

    One of the highest meteorological masts in Europe is situated on Rödeser Berg, a hill near Kassel. The research facility with its measurement devices records the wind conditions up to a height of 200 metres. The aim is to measure the impact of forest areas and low mountain ranges on the wind profile and flow characteristics. The results will help to improve the meteorological models for assessing sites, will make it possible to estimate the loads on individual system components in more detail and will help to further develop the laser-based LiDAR method.  more...

    Metal foam – a material for heat engineering

    Metal foams are increasingly developing into materials with diverse uses. While metal foams with closed pores have already become established as rigid and strong lightweight materials, the open-cell variant is suitable for thermal engineering applications. Until now, the material has been rarely used in heat exchangers or coolers because the production is expensive and its application little tested. Researchers at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Dresden now want to change this.  more...

    Fuel cell generates electricity and heat for homes

    Highly efficient, low-emission and quiet: as small-scale combined-heat-and-power stations, new fuel cell heating units produce heat energy and electrical energy with an efficiency of over 90 per cent. They have proven themselves in extensive tests in single and two-family homes, and their operation and design have been improved incrementally. The first units are now on the market. They run on natural gas, and on hydrogen and methane produced using renewable energy or biomass. Decentralised fuel cells can generate demand-oriented electricity, and they can be used in a grid-friendly or grid-independent way.  more...

    Assessing solar houses in energy and economic terms

    With the German Energy Savings Ordinance 2016, the maximum value allowed for the annual primary energy requirement for new residential buildings has been reduced by a quarter. This is not a problem in solar houses: they require a maximum of 15 kWh/(m2p.a.) of primary energy for heating energy and auxiliary power and are therefore well below the requirements of passive houses. The cost of this good CO2 balance can be determined using a newly developed simulation method.  more...
     

    Fun in a passive house pool

    The monitoring shows that the thermal heat and electricity consumption can be reduced even further during ongoing operation if the building is well-regulated, optimised and continually monitored. The public swimming pool complex in Bamberg consumes over 50 per cent less heat than comparable leisure pool facilities. A thermally high-quality building envelope allows indoor air humidities of up to 64 per cent. This reduces the pool water's evaporation rate and the necessary air change rate for providing dehumidification. This therefore also reduces the electricity and heating requirements.  more...
