    Pilot production launched for superconductors

    He had to wait 30 years for this moment: Dr Georg Bednorz, a Nobel Laureate in Physics, was present in the Rhineland town of Rheinbach to see the pilot production of high-temperature superconductors begin. It is intended to provide further insights into the manufacture of these almost resistance-free conductors and pave the way for their large-scale series production. The technology is therefore taking a further step towards market maturity.  more...

    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...
     

    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...
     

    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...

    Electricity grid with strong genes

    The electricity grid is both dynamic and sluggish at the same time. On the one hand, it distributes electricity with rapidly fluctuating loads. On the other hand it takes a long time before constructional changes can be planned and carried out, which is due to both technical and social reasons. This makes it important to assess future scenarios with simulations. Scientists at RWTH Aachen are achieving this with their GENESYS software program.  more...

    Securely controlling dynamic electricity grids

    The construction of power plants that generate electricity from the wind and sun continues apace. In particular at high sea, but also in rural areas, there is still considerable development potential during the next few years amounting to several gigawatts. The load centres, however, are situated in the metropolitan areas in the middle and south of the country. It is therefore important to integrate the locally created surplus capacities in an intelligent manner.  more...
     

    Preparing the electricity grid for electric vehicles and heat pumps

    The electricity grids in Germany have to be expanded to cope with decentralised generators and increasingly more large-scale loads. For grid operators it is therefore important to gain an overview of the necessary measures and their effectiveness even before installing new operating resources. Special simulation and planning tools are suitable for this. As part of the Novel E-Mobility Grid (NEMO) research project, scientists at the Fraunhofer Institute for Solar Energy Systems ISE have developed a software programme that can help to analyse and plan power grids.  more...
