    Energy storage systems in 2030

    What role will functional storage systems play in the energy supply system of the future? Which system infrastructure can economically secure a reliable energy supply in 2030? And what measures must the government take so that this system infrastructure can prevail on the market? Scientists at the Research Center for Energy Economics (FfE) are trying to get to the bottom of these questions with an ongoing study. The results are now available.  more...
     

    Stadtwerke Augsburg testing superconducting fault current limiter

    The ASSIST project shows how decentralised feed-in systems can be safely integrated into a medium-voltage network. Since 15 March, a superconducting fault current limiter ensures that the electricity fed from a cogeneration engine test rig into the electricity grid belonging to Stadtwerke Augsburg municipal utility company is protected against short circuits. Last week, Thomas Janetscheck from Stadtwerke Augsburg presented the system at the ZIEHL V superconductor conference in Munich.  more...
     

    Modelling power supply for 2050

    By 2050, the goal is for renewable energy sources to generate at least 80 per cent of power. In order to then still guarantee reliable supply at affordable prices, the entire energy system must be adapted and converted in a step-by-step process. The increasing share of fluctuating energy sources requires a flexible system that can react quickly. A research project demonstrates the degree of grid expansion, storage and new regulation opportunities that are technically required for this purpose, and which make economic sense.  more...
     

    TU Darmstadt opens research factory

    Last week, the ETA model factory officially opened its doors. Here, scientists at the Technical University (TU) Darmstadt are researching under real conditions and at full scale how industry can use energy more efficiently by linking all building and production components. By considering the entire system – consisting of machines, energy storage systems, building technology and the building envelope – the intention is to reduce the primary energy requirement in production by 40 per cent.  more...
     

    Transmitting more electricity in the decentralised grid

    There is a tolerance range for grid voltage that grid operators must comply with. Power supply may collapse if the voltage drops below the lower limit. If it exceeds that limit, equipment can be damaged. More feed-in leads to a higher voltage if there are no consumers for this energy. Especially in rural areas, this may be a problem due to the large number of decentralised systems and sparse population.  more...

    A second life for car batteries

    The demands that drivers place on electric vehicles are high indeed: both range and performance have to be sufficient. In addition, batteries are subject to a steady decline of capacity. As performance and capacity deteriorate, a new battery is needed. Retired units are still suitable for other purposes, for example, for raising the self-consumption of solar power systems or supporting the grid.  more...

    Electric cars stabilise the grid

    How can users of electric cars recharge their batteries flexibly, help relieve the grids and save money in doing so? Researchers examined at what point electric cars become a benefit for grid operators and vehicle owners. Their field test demonstrates the conditions this depends on.  more...
     

    AmpaCity receives innovation award

    Since the spring of 2014, a superconducting cable helps to ensure that the lights stay on in the centre of Essen. It transmits up to 40 megawatts of electricity – almost without loss. With AmpaCity, researchers from science and the electricity industry are demonstrating how high voltage lines and transformer substations could be eliminated in urban areas. On 20 January 2016, the project, which is funded by the German Federal Ministry for Economic Affairs and Energy, was conferred the German Innovation Prize for Climate and the Environment.  more...
     

    Neckarpark Stuttgart: Heat from waste water

    Sewage stinks and is filthy – but it is suitable for supplying heating and cooling to buildings. In Stuttgart’s new Neckarpark urban district, the energy in the municipal waste water is extracted by means of a trough heat exchanger in the sewage channel and utilised via a low-temperature local heating network. This provides the basis of the energy concept for the new district, which is being created with highly energy-efficient buildings on the brownfield site belonging to the former Bad Cannstatt railway freight depot.  more...
     

    Lime storage systems: Cheap, efficient and sustainable

    At the German Aerospace Centre (DLR), researchers are using lime as a storage medium in a specially developed heat storage system. This enables heat to be stored in the form of a reversible reaction. Such storage systems can help large amounts of energy to be used more efficiently in industrial processes and households. The new plant has now been put into operation.  more...
