    Flexible turbomachines stabilise the power grid

    In future, conventional power plants will need to become more flexible in order to compensate for the fluctuating power generation by renewables. This requires modified gas and steam turbines. These will have to work more frequently under partial load, with more start-up and shut-down cycles and function with changing fuels. AG Turbo has compiled the research and development objectives for these new framework conditions in the ECOFLEX-turbo programme.  more...

    Syngas from biocoals

    Organic waste, thinning wood, straw and landscape management waste products are still little used for generating energy. This is because such biogenic residues have poor combustion properties owing to their inhomogeneous composition or high moisture contents. However, researchers from the Technical University of Munich and SunCoal Industries are now producing biocoal from such material using a new process.  more...
     

    The future of power plants

    The "Flexible Energy Conversion" research network was founded in Berlin at the end of February 2017. Here, researchers and developers from the conventional power plant technology and solar thermal power plant fields will jointly develop future strategies. The goals: To increase the flexibility of large-scale power plants, develop new large-scale storage systems, extensively research the use of hydrogen in power plant processes and in particular optimise the economic efficiency of solar power plants.  more...

    Pilot production of thermoelectric modules

    Thermoelectric generators convert waste heat directly into electricity. They utilise temperature differences and are paving the way for more energy-efficient production processes. However, the technology has previously led a niche existence because the module production is labour-intensive and therefore expensive. Researchers from Freiburg now want to improve this.  more...
     

    Energy centre supplies Giessen University Hospital

    Giessen’s municipal utility company and University Hospital have jointly constructed the first energy centre to be integrated into a local heating and cooling network. The newly developed combined cooling, heating and power system ensures an uninterrupted supply to the hospital. It saves 21.7 % of the primary energy and 33.6 % of the CO2 emissions.  more...
     

    Clean use of landfill gas

    In the production of landfill gas, other gases are produced alongside the desired methane that damage motors and turbines. To protect these plant components, trace compounds of organic silicon contained in the gases are separated beforehand, e.g. by means of adsorption. The high consumption of the adsorbent, however, endangers the efficiency of the process. A research team has developed an on-site regeneration method for the adsorbent. This can increase the efficiency of the energy recovery of landfill gas.  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...
     

    Bee and bumblebee begin field tests

    As part of a joint project with Vattenfall and ZAE Bayern, scientists from the TU Berlin have developed two new absorption chillers. The 50-kW unit, which the researchers have nicknamed Bee, and the larger 160-kW unit called Bumblebee use heat at a low temperature level for generating cooling energy. The prototypes are smaller, lighter and more powerful than comparable systems on the market. A field test is now starting.  more...
