    Steel beats copper

    The so-called embossing stretch forming process is an established method used in the manufacture of radiators. Researchers have now adapted this process for the production of solar absorbers. Instead of using expensive copper, this method also enables steel and aluminium to be processed in large numbers and with flexible lengths. An adapted channel design compensates for the lower thermal conductivity of steel. This enables them to achieve the same thermal efficiency as conventional absorbers – and also save money.  more...
     

    Interim findings of the Energy Storage Research Initiative

    Which contribution can energy storage systems make to the energy transition? How can they be employed economically? And what are the future research priorities? These were the questions answered during the 2nd status seminar on energy storage systems in Berlin last week. Half-time for the Energy Storage Research Initiative, and time to look at the score.  more...
     

    Standardised feed in of solar heat

    Solar thermal systems are very suitable for retrofitting into existing buildings. However, a lack of standardisation exists when coupling the system to a district heating network. Viessmann and the Technical University of Dresden are therefore developing suggestions for future standardisation. This should help to reduce the planning effort required and save costs through unification of the various circuit variants.  more...
     

    Superlubricity reduces friction

    The forces of friction play a central role in vehicles. They inevitably lead to higher fuel consumption and wear in and on all moving parts. Researchers are therefore searching for ways to keep the forces of friction as low as possible. One area of research is diamond-like carbon coatings (DLC). In an interview, Dr Johann Schnagl, Project Manager in the BMW Group and Professor Dr Michael Moseler from Fraunhofer IWM explained this area of research.  more...

    Biomass in coal-fired power plants can improve carbon footprint

    Using simulations for fuel flexibility, researchers hope to uncover the true extent of potential improvement to the carbon footprint of existing power stations. One option that exists is to add biomass to coal in the form of woodchips. Though at higher rates of co-combustion in particular, electrical power consumption in the crushing process increases enormously. This can be reduced with the proper pretreatment.  more...

    New forging process reduces proportion of burrs

    A newly developed forging process is saving material and energy. In the “multi-directional forging” process, researchers have been able to reduce the proportion of burrs when forging crankshafts from 54 to 7 per cent, with associated energy savings of roughly 20 per cent. The process has already been successfully tested in industrial application.  more...
     

    Stepping-up battery research

    An expert commission of the Technology Network of the International Energy Agency held a conference in Berlin on the topic of energy storage devices. Representatives of various member states voiced recommendations for future research into storage devices in a workshop. Battery technology was focussed on.  more...
     

    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...

    Batteries in the low-voltage grid for more PV energy

    In areas where already a large number of photovoltaic systems are installed, impermissibly high voltages can occur in the power grid on sunny days. It therefore needs to be clarified how the energy generated can be optimally used both technically and economically. One idea is that new charging strategies for batteries can effectively relieve the grid by optimally integrating the energy storage systems.  more...

    Gas and heating networks act as energy storage systems

    Heating and gas networks can balance out fluctuations in the electricity grid. But how flexibly can surplus electricity be indirectly stored? In the Multi-Grid Storage project, scientists have investigated how it can be best of all stored in the form of heat or gas and then made available again as electrical energy as soon as it is required.  more...
