    Hybrid building machinery

    Hybrid drives make construction machinery not only more economical and quieter – the power from the two engines also provides power reserves for special loads. The advantages of combining a combustion engine with an electric drive have been demonstrated by the DEUTZ engine manufacturing company from Cologne using an excavator. In order to realise the full savings potential, the engineers have also closely examined the auxiliary units as part of the Green Industrial Diesel (GRID) project.  more...

    Start signal for model factory

    Mechanical engineers, construction engineers, architects and industry experts have developed a new production facility: the so-called ETA factory. The foundation stone was laid for it on 12 August 2014. This initiates the start of construction of the model factory at the Technische Universität Darmstadt, in which in future machines, building technology and the building envelope can be energetically linked and perfected. It is scheduled to open in October 2015.  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...

    Durable diesel engine with electronic control

    The engine manufacturers Hatz developed a diesel engine in the performance class of up to 56 kW with a common-rail injection system. Combined with a more compact design, the Lower Bavarian engineering company significantly reduced consumption. They also reduced both nitrogen oxide emissions with exhaust gas recirculation, and soot particle emissions with an entirely new combustion system. The engine concept developed in the research project is the foundation for a new line of water-cooled diesel engines.  more...

    “Heat pumps are ready for the smart grid”

    Over the last few years, heat pumps have become more efficient. In a recent interview, Marek Miara, head of the heat pump unit at the Fraunhofer Institute for Solar Energy Systems ISE, talked about research results and future development potential. His team has completed three large-scale monitoring projects in old and new buildings.  more...

    Highly efficient pump technology becomes obligatory

    The age of unregulated, glandless circulation pumps is coming to an end. Several technically outdated series with electronic controls will also no longer be available next year. They do not meet the strict efficiency requirements of the new EU ordinance subject to the European Ecodesign Directive (ErP), which comes into force in 2013.  more...

    Getting things moving with little energy

    47 per cent of the net electricity consumed in Germany is used by industry. Particularly in automation technology, robot arms would not move without drive energy and heavy components would remain at a standstill in the production. A potential study recommends new solutions for energy optimised system operations. The intention is to increase the energy productivity of the electrical and pneumatic drive technology by up to 50 per cent.  more...

    Researching facts for energy research

    The Internet offers rapid and convenient access to information - including for energy research. However, when it comes to obtaining reliable, complete and quotable information for research purposes, there is no real alternative to using specialist databases. This is the conclusion of scientists from the ETDE (Energy Technology Data Exchange). In a study they compared the search results provided by their ETDEWEB database with those from Google and Google Scholar, whereby they used search terms from different areas concerned with energy transformation and utilisation. The main thematic focus was on renewable energies, but energy efficient technologies such as recycling waste heat or utilising daylight in office buildings were also looked at.  more...

    Ideas and concepts for energy research

    The German Federal Ministry of Economics and Technology has published a strategy paper entitled "Eckpunkte und Leitlinien zur Weiterentwicklung der Energieforschungspolitik der Bundesregierung (Cornerstones and guidelines for the continued development of the German federal government's energy research policy)". The detailed analyses and suggestions were developed as a result of the cooperation between a number of institutes in the Helmholtz Association of German Research Centres as part of a broadly based consultation process.  more...
