    "One million electric cars are feasible by 2025"

    Expensive, short ranges and long charging times: Today's batteries for electric vehicles have a negative image. However, the electric car is actually ready for series production. Well at least almost. In the BINE interview, Professor Martin Winter from the MEET Battery Research Center at Westfälische Wilhelms-Universität Münster and the Helmholtz Institute Münster talks about the hurdles that still need to be overcome and how it will be possible to get considerably more electric vehicles onto the streets in the coming years.  more...
     

    Predictable heat yield

    The demand for large-scale solar thermal systems in district heating networks is increasing. Thereby the need for more powerful calculation programs is also increasing. Investors require predictions of the expected heat yield of solar thermal systems for their projects. A new calculation program shall now make that possible.  more...

    Large storage tank developed for small spaces

    To heat an apartment building highly efficiently, using a solar power system or combined heat and power plant for example, you need large thermal storage tanks. They often do not fit through standard door openings in existing buildings. Scientists developed a compact storage tank consisting of multiple modules, which is not assembled fully until it reaches the boiler room. Heat losses are lower than with standard cascade models. Individual tanks no longer have to be connected.  more...
     

    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...
     

    "We have to increase our efforts!"

    The first ENERGIEWENDEBAUEN conference took place in Berlin from 30 - 31 January, 2017. Some 350 participants from research, academia, architecture and planning offices, politics, energy suppliers, cities and municipalities as well as the real estate industry discussed how the energy supply of buildings and districts could be made future-proof. The aim of the German federal government is to create a climate-neutral building stock by 2050. This will not be easy to achieve.  more...

    Superconductors for the medium-voltage grid

    Scientists are testing the longest high-temperature superconducting cable in the world under real conditions in Essen. One kilometre long, it connects two substations in the inner city. It replaces a conventional 110 kV line and renders one substation in the inner city obsolete. After two years of testing, it has passed the field test. It could be a blueprint for the future power supply system in urban areas.  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...

    Networked factory stabilises the grid

    The factory of the future is flexible and networks the energy flows between machinery and buildings. The so-called Phi Factory is not only very energy-efficient, it also helps stabilise the electrical supply grid. The new model factory relies on a high share of renewable energy and helps smooth out electricity supply fluctuations.  more...

    Storing surplus electricity in the natural gas network

    Surplus electricity can be used in Power-to-Gas systems to generate hydrogen by means of electrolysis. Downstream methanation provides a possibility for storing the remaining gas that cannot be directly used or fed into the natural gas network. The initial, highly promising results for a newly developed biological process have now been presented. The test facility has a low energy requirement and the process is continuous. The system is suitable for decentralised and small systems.  more...
     

    The hotline in the grid

    The electricity grid that has been used for decades reaches its limits when transporting increasing amounts of electricity over long distances. There are already limiting bottlenecks. One way to integrate more wind and solar power into the grid is provided by overhead lines with a higher maximum temperature. These can transport more electricity, enabling grid congestion to be avoided. One problem, though, is that metals expand more at high temperatures. As a result the line lengthens and sags more. However, special high-temperature conductors can provide a remedy here.  more...
