    Gas and heating networks act as energy storage systems

    Heating and gas networks can balance out fluctuations in the electricity grid. But how flexibly can surplus electricity be indirectly stored? In the Multi-Grid Storage project, scientists have investigated how it can be best of all stored in the form of heat or gas and then made available again as electrical energy as soon as it is required.  more...
     

    Identifying risks and minimising them through regulations

    How safe and reliable are photovoltaic installations with lithium-ion storage systems? In order to find out, scientists are investigating different plant systems. The intention is to identify possible weak points – such as during transport and installation – so that they can be taken into account in future standardisation work.  more...
     

    Publicising expertise for energy-optimised buildings worldwide

    The Energy Efficiency Export Initiative is expanding its funding. The intention is that German design and technology skills in the energy-optimised construction field shall now also be publicised worldwide. The support is being organised by the German chambers of foreign trade in the form of tours of buildings, expert workshops and media relations work.

    Quadruple solar cell achieves record-breaking efficiency

    Researchers have developed a quadruple solar cell that converts 46 per cent of sunlight into electricity. The high-performance cells achieve this record-breaking efficiency in connection with optics that concentrate the light 508 times. If these cells were built in concentrator modules, energy would be produced even more economically in regions with high levels of sun.  more...
     

    Energy diet for confectionary manufacturer

    The confectionary manufacturer, Ferrero, and the packaging specialist, Junghans, want to save half the energy that they previously required for production. With the help of a new energy monitoring system, they also want to become smart consumers: They would then purchase energy, when it is cheapest for them. A recently started research project will define what the companies have to change in terms of production and management.  more...

    Heating system keeps rotor blades ice-free

    In cold climate zones, the wind is particularly strong meaning best conditions for a wind turbine. However, in the cold temperatures there is the danger of ice that can freeze onto rotor blades. This can lead to imbalances, impairment of the rotor blade’s aerodynamics and a drop in the efficiency of the turbine. The so-called carbon-nanotube coating offers a solution.  more...

    How electric vehicles can be of use to the grid

    The batteries in electric vehicles can store surplus energy from the electricity grid. By the same token, they can feed back electrical energy to the grid at times of high demand for electricity. As part of the NET-INES project, scientists are investigating different charging and discharging strategies as well as the opportunities to market this service. For this purpose, they surveyed more than 600 vehicle owners.  more...

    The Sistine Chapel in a new light

    Over the last number of months, the Sistine Chapel has been fitted out with LEDs as part of an EU pilot project. The LEDs provide greatly enhanced illumination compared to the existing lighting system dating back to the 1980s and consume less than half the amount of electricity. The spectrum of an LED contains virtually no ultraviolet and infrared radiation that might damage the artworks. This means that, unlike before, the lights can now be used directly inside the building.  more...

    Low-cost collector integration in buildings

    To promote the spread of solar thermal energy further, the cost of system components must come down. Under the stewardship of the Fraunhofer Institute for Solar Energy Systems ISE, scientists have developed collectors with absorbers and coverings produced from low-cost plastic. Over 30 terraced houses in the Mortensrud neighbourhood near Oslo in Norway have been fitted with the new technology and showcased recently to the public.  more...
     

    Thermochemical storage systems for continuous load

    Through the “Thermochemical energy storage unit for thermal power plants and industrial heat” project (TcET), researchers at TU Munich hope to increase the flexibility of fossil fuel power plants. The trick in all of this: If no or a reduced volume of electrical power is required, the plant does not power down. The surplus energy rather is temporarily stored in thermochemical storage systems.  more...
