    Storing solar energy with new materials

    The interdisciplinary NEOTHERM junior research group at Otto von Guericke University in Magdeburg is developing new materials for storing thermal energy. Using new composite materials, the scientists at the Faculty of Process and Systems Engineering (FVST) want to recover and store unused solar thermal energy and waste heat from industry. This energy can be used, for example, for heating domestic hot water or for space heating.  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...
     

    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...

    Increased efficiency for power supplies

    Switched-mode power supplies are used in almost every electronic device including television sets, computers and monitors. Their efficiency is 80% to over 90% depending on the build quality. About one third of the power losses are caused by alternating magnetic fields in coils and transformers. Together with industry partners, researchers at the Friedrich-Alexander-Universität Erlangen-Nürnberg looked into ways to improve the energy efficiency of these components. Extrapolated to the total number of units in operation, even small improvements can bring about significant power savings. Reduced thermal loss allows for the construction of smaller and lighter units with less material invested.  more...

    Lithium-ion batteries in mass production

    At the Karlsruhe Institute of Technology (KIT), the small-scale production of lithium-ion cells has begun. The goal in the research factory is to reduce production costs by developing process engineering for the mass market. Researchers aim to use this to help the lithium-ion batteries make a breakthrough as stationary and mobile storage facilities.  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...

    Using flare gas as a fuel

    Currently, the gas which is produced when mineral oil is mined is simply flared. This creates emissions and the energy potential remains unused. In the “Syngas to Fuel” project, the Technische Universität Bergakademie Freiberg has developed a solution to the problem in collaboration with systems planner Chemieanlagenbau Chemnitz.  more...
     

    Energy-efficient ETA Factory launched

    The primary energy requirements of industrial production shall be reduced by up to 40 per cent. That is the aim of twelve companies and five research institutions and universities. In the newly launched “ETA Factory” research project, they are developing the energy-saving factory of the future under the auspices of the Technische Universität Darmstadt.  more...

    The supermarket of the future saves energy

    The energy savings division at the discount store Aldi Süd in Rastatt should in the future only need two-thirds of the primary energy usually required for refrigeration, heating, ventilation, air conditioning and lighting. A compressor pack with carbon dioxide as a coolant which has been developed in-house, and which is coupled to borehole heat exchangers, not only cools food, but also provides temperature control for indoor areas.  In the third year of operation, the amount of energy consumed is coming close to the ambitious target levels.  more...
     

    Degreasing aluminium foil using corona treatment

    Rolls of aluminium foil commonly used in households have already been in the oven for up to one hundred hours before coming into contact with food. The heat causes the separating agent needed during production to evaporate. Without the grease, the foil cannot be rolled so thinly, and the consumption of aluminium, which requires a considerable amount of energy, would be greater. The aim is to replace the costly degreasing procedure with a corona treatment. During this procedure, high-energy electrons come into contact with the foil. The method can be integrated inline, in other words directly, into the production flow.  more...
