    FLOX burners turn mega

    In many high-temperature processes, so-called FLOX burners provide optimum fuel utilisation with low pollutant emissions. Flameless oxidation – known as FLOX – has already become established in the middle output range between 20 and 300 kilowatts. Scientists are now working as part of the Mega-FLOX project to expand the output range. This opens up new areas of application.  more...
     

    It's turbulent offshore

    In offshore wind farms, the front turbines receive the most wind. They cause kilometre-long vortexes with slower wind and increased turbulence, which affects the downstream wind turbines. Previous methods that mimic such wakes are inaccurate or require considerable computation. In order to better understand these wake effects, scientists have therefore developed a new model and software to help optimise farms.  more...
     

    Solar thermal and photovoltaic power plants in comparison

    How will the market for photovoltaic and solar thermal power plants develop in the coming decades? Which technology is economically more efficient? And what opportunities are offered by combined power plant systems in sunny regions? A study carried out by the German Aerospace Centre (DLR) has investigated the development of these power plants until 2030.  more...

    Learning and working in an energy-plus school

    Uhland School in Stuttgart, which dates back to the 1950s, no longer accorded with today's structural and energetic standards. The renovation work is now almost complete and the City of Stuttgart is getting its first energy-plus school. A photovoltaic system on the roof and façade of the building covers the electricity requirement.  more...
     

    Processing and recycling titanium waste

    Titanium components account for up to 15 per cent of the total weight of modern aircraft. The material is light and very stable. However, up to 95 per cent of the original titanium is left over as waste chips during the entire manufacturing process. These are contaminated and until now it has not been possible to recycle them so that they are suitable for reuse in aircraft construction. Scientists have therefore developed a method that can process and recycle titanium chips with high purity.  more...

    Storing surplus electricity in the natural gas network

    Surplus electricity can be used in Power-to-Gas systems to generate hydrogen by means of electrolysis. Downstream methanation provides a possibility for storing the remaining gas that cannot be directly used or fed into the natural gas network. The initial, highly promising results for a newly developed biological process have now been presented. The test facility has a low energy requirement and the process is continuous. The system is suitable for decentralised and small systems.  more...
     

    Expanding the electricity grid for the energy transition

    Experts from science, industry and politics met on 22 and 23 September 2016 at the first status conference on "Future-proof Power Grids" in Berlin. More than 300 delegates followed the invitation of the German federal government and offered an insight into their current research on the subject of grid expansion. Since the beginning of the "Future-proof Power Grids" funding initiative in 2013, the participating German federal ministries have funded more than 300 projects with around 140 million euros.  more...
     

    Exhaust heat cools lorry cab

    Time for a break! The driver stops his lorry at the truck stop. To ensure that the cabin also remains cool even in summer, the engine also continues idling when the lorry is parked, often for hours. This produces noise and wastes fuel. However, researchers at the University of Stuttgart have now demonstrated that pleasant temperatures can still be reached even when the engine is switched off and there are no additional energy inputs. They have developed a special adsorption chiller. This utilises the exhaust heat produced while driving for air-conditioning the parked vehicle.  more...

    Research on large-scale battery storage system

    The modular, large-scale M5BAT battery storage system recently began operating in Aachen, Germany. With a 5 MW output and a storage capacity of 5 megawatt-hours, it is the largest battery storage system currently being researched. Together with industrial partners, scientists at RWTH Aachen are testing the interaction of five different battery types and are developing business models for decentralised storage systems in actual grid operation.  more...
     

    Networked micro-CHP plant in field test

    Small engine-based cogeneration plants and fuel cells can be combined together and operated as a network. Such a regional virtual power plant (RVPP) is currently being tested by researchers at the TU Dresden and EWE AG in the Oldenburg area. They are developing control and regulation concepts for operating in networked systems until the end of 2017.  more...
