    Sphere storage system receives German Renewables Award

    One year ago, scientists sank a concrete sphere one hundred metres below the surface of Lake Constance. The three-metre-diameter hollow body provided a functional model for an offshore pumped storage power plant. Now they have received the “German Renewables Award 2017” for their research work. The developers at Fraunhofer IWES are already planning the next step.  more...
     

    Refrigerators stabilise the electricity grid

    Refrigerators that consume electricity precisely when the wind and the sun provide excess electrical energy, and which during slack periods maintain their cooling temperature without additional energy input, would greatly relieve the grid. Scientists from ZAE Bayern are investigating the costs and benefits of such a load shift together with industrial partners. For this purpose they are increasing the thermal inertia of an efficient standard refrigerator by installing latent heat storage units. The test device can thereby bridge longer standstill times.  more...
     

    Modular battery storage system supplies balancing energy

    How can large-scale battery storage systems help stabilise electricity grids and at the same time be profitable? This question is being investigated by scientists at RWTH Aachen University in collaboration with industrial partners using the large-scale M5BAT battery storage system. Using a modular and flexibly scalable batteryinverter concept they are testing the interaction of different accumulator technologies and are developing business models for decentralised storage systems in real grid operation.  more...

    Intermediate storage of renewables

    How could more renewable energies be used that also stabilise the grid? To answer this question, researchers at the MEET Battery Research Centre at Münster University developed a new energy storage system based on dual-ion battery technology. Its long service life is promising for stationary applications.  more...
     

    “The energy system of today is much more complex than in the past”

    Preparations are currently under way for a new energy research programme, which the German Federal Government intends to publish in the coming legislative period. In preparation, the German Federal Ministry for Economic Affairs and Energy has started a discussion process between representatives from industry, science and politics in order to identify relevant fields of research. In this interview Dr Johannes Tambornino, Head of Energy Strategies and System Analysis at Project Management Jülich speaks about the growing importance of system analysis for energy research.  more...

    Flexible turbomachines stabilise the power grid

    In future, conventional power plants will need to become more flexible in order to compensate for the fluctuating power generation by renewables. This requires modified gas and steam turbines. These will have to work more frequently under partial load, with more start-up and shut-down cycles and function with changing fuels. AG Turbo has compiled the research and development objectives for these new framework conditions in the ECOFLEX-turbo programme.  more...

    40 years of energy research

    Last week, on 2nd May 2017, the German Federal Minister for Economic Affairs, Brigitte Zypries, opened the celebration for the anniversary of “40 years of energy research programmes in the German Federal Government” in the historic conference rooms of the German Federal Ministry for Economic Affairs and Energy in Berlin. She emphasised that research and development are important components in the large modernisation and investment project for energy transformation in Germany.

    Energy transition in transport

    Until now, the energy and transport sectors were considered separately from one another in the energy balance. The “Energy transition in transport” funding initiative by the German Federal Ministry for Economic Affairs and Energy (BMWi) is entering into force to change that. It is intended to help bring the energy and transport sectors closer together and advance the technological possibilities in a cross-system approach encompassing a wide range of vehicles.  more...

    Electromobility - What drives us now and in the future

    Highly efficient, low-noise and zero-emission: the electric powertrain offers dynamic mobility, can integrate renewable energies and makes the transport sector less dependent on crude oil as an energy source. However, which technology will dominate electric vehicles of the future: batteries or fuel cells? An either-or decision is not necessary.  more...
     

    Concrete sphere in the sea successfully stores electricity

    How can energy be stored near offshore wind farms in the future? Researchers have developed a new storage system that works with hollow spheres on the seabed. The principle is similar to conventional pumped storage power plants. At the end of 2016, the researchers at Fraunhofer Institute for Wind Energy and Energy System Technology IWES tested a three-metre concrete prototype in Lake Constance. The test results are highly promising.  more...
