    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...

    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...
     

    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...

    Fuel cell heating units ready for market

    In Germany’s largest fuel cell heating unit field test, 350 systems by various manufacturers have been tested in homes to date. This is in preparation for market launch and mass production. By mid-2016, up to 500 units are to be tested in the “Callux” field test.  more...
     

    CO2 capturing using lime

    CO2 can be separated from the flue gases from power plants. However, the processes developed for this have been very expansive until now. When capturing CO2 using quicklime, on the other hand, the costs are much lower – around 15 euros per tonne of CO2. These plants for capturing CO2 from exhaust gases can be retrofitted in existing power plants. The Technische Universität Darmstadt has demonstrated the process using a one-megawatt pilot plant. The solid material produced – quicklime – could be interesting for cement plants, since this would reduce their energy consumption.  more...

    Where renewable power plants pay off

    With the FreeGreenius simulation programme, engineers can calculate which yields can be achieved by a renewable power plant project at a specific location. In addition, the tool also enables them to plan how the installation must be designed and sized in order to feed in the desired amount of electricity into the grid. Designers of solar power plants and wind turbines can therefore gain an initial insight into whether a power plant is viable and under what conditions. The German Aerospace Centre (DLR) offers the software free of charge for downloading.  more...

    Efficiently capturing carbon dioxide with spray scrubbers

    Spray scrubbers have been successfully used in power plants for years for desulphurising flue gas. Now it is intended that they should scrub another material – namely climate-harming carbon dioxide (CO2). Until now a hurdle preventing large-scale CO2 capturing has been the high investment costs for the plant technology and the considerable amount of energy required for the operation. The University of Stuttgart is therefore working with partners to improve this process.  more...
     

    Thinner tube walls make power plants more flexible

    A consortium from science, manufacturers and power plant operators is investigating the new materials under real conditions at the GKM power plant in Mannheim (Grosskraftwerk Mannheim). Professor Karl Maile, Commercial Director of the Materials Testing Institute at the University of Stuttgart (MPA Stuttgart), is heading the scientific support research on the high-temperature material test facilities (HWT I and II). In the interview, he talked about the importance of the ongoing material development for the flexibility and efficiency of power plants.  more...
     

    Solar thermal power plants

    The annual solar irradiation on the earth provides more than 8,000 times the world’s energy requirements. Mathematically speaking, about 1 % of the surface area of the Sahara Desert is sufficient in order to meet the world’s electricity requirements with solar thermal power plants. A solar thermal power plant was already constructed close to Cairo at the beginning of the 20th century. Using parabolic mirrors, the power plant captured and concentrated solar energy and used it to heat oil for boiling water. This in turn was used to drive steam turbines and produce electricity.  more...
     

    Ceramics reduce energy needed to separate air

    Cryogenic air separation, a process employed to produce oxygen, requires a lot of energy. This high energy consumption impairs the efficiency of a number of industrial processes and procedures used to separate carbon dioxide from exhaust gases. In the context of the MEM-OXYCOAL research project headed by RWTH Aachen University, scientists have developed membranes that improve the energy efficiency of oxygen separation.  more...
