    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...
     

    Superlubricity in vehicles

    During the long development history of mechanical engineering, engineers have substantially exhausted the traditional methods of reducing friction. Further optimisations are mostly just a matter of a few per cent. Innovative coatings made of diamond-like, shiny black carbon compounds can now exploit their advantages. They combine extraordinary lubricity with anti-adhesive properties, chemical stability and extreme material hardness. In the Pegasus research project, scientists from research and industry are working on their large-scale use for drive trains in vehicles.  more...
     

    Copper furnace recycles more scrap metal

    With a new, tiltable rotary drum refining furnace, an industrial enterprise has succeeded in melting more copper at once. This also reduces the emissions from dioxins and other organic pollutants. The technical trials and the development of the energy efficient furnace were funded by the German Federal Ministry for the Environment as a demonstration project within its Environmental Innovation Programme.  more...
     

    Getting things moving with little energy

    47 per cent of the net electricity consumed in Germany is used by industry. Particularly in automation technology, robot arms would not move without drive energy and heavy components would remain at a standstill in the production. A potential study recommends new solutions for energy optimised system operations. The intention is to increase the energy productivity of the electrical and pneumatic drive technology by up to 50 per cent.  more...
