    Power consumption for computing centre halved

    Electricity consumption for a computing centre can be halved without restrictions for users. With this in mind, scientists in the AC4DC (Adaptive Computing for Green Data Centers) research project developed a new control system which optimally coordinates the server, cooling system and all other components of a computing centre. This holistic concept is based on a study of methods for optimising the energy consumption of computing centres.  more...
     

    “Secure provision of data centres with renewable energies”

    The RenewIT project is researching how data centres can make greater use of renewable energies. That is an important goal for project partner Thorsten Urbaneck, who is a private lecturer at Chemnitz University of Technology. This is because it is estimated that data centres consume two per cent of the electricity used in Europe – and the trend is increasing.  more...

    Making machine tools work more efficiently

    When machine tools process complex components, often only about 20 % of the energy deployed flows into the actual metal cutting processes. The main loads tend to be peripheral machine components, such as cooling systems or hydraulic drives. In the Maxiem project, scientists from the Technische Universtät Darmstadt and industrial partners are showing how this energy requirement can, in ideal cases, be more than halved.  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...

    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...
     

    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...

    Energy-efficient finishing in mechanical engineering

    When producing machine components, the grinding stage is a production process with comparatively low energy efficiency. Up to 90% of the energy deployed is released as frictional heat. Large amounts of lubricants and coolants flood the workpieces and tools to cool them. The supply of coolants and their processing require enormous expenditure, including in terms of the energy. Researchers from industry and science have therefore jointly developed new processes that produce significant savings potential with minimum lubrication.  more...
