    Adapting chlorine production to the electricity supply

    The chemical industry is the second largest consumer of electricity within German industry. Using the example of energy-intensive chlorine-alkali electrolysis, scientists are now investigating to what extent this process can contribute to managing loads in the power grid. To achieve this the production needs to be adapted to the intermittent electricity supply.  more...
     

    Better insulation ensures more reliable operation

    If the receiver insulation is damaged, the efficiency of solar tower power plants decreases. Repairing or replacing the insulation takes time and money. In conjunction with industrial partners, scientists at the German Aerospace Center (DLR) have developed cavity insulation that utilises new material combinations. Tests show that the market-ready insulation is more robust than previous models.  more...
     

    When wind energy goes to school

    Pupils have now gone back to school in all of Germany's federal states, and the curricula for the new school year have been set. Experts led by the Independent Institute for Environmental Issues (UfU) have investigated how renewable energies can be better integrated into lessons as a subject area. For this purpose they have developed teaching materials and analysed the benefits and potential of wind turbines and photovoltaic systems at educational facilities.  more...
     

    Pentagonal mirror reflects the sun precisely

    In solar tower power plants, multiple mirrors – called heliostats – direct the sunlight to the receiver at the top of the tower. Heliostats have previously had a rectangular shape. However, engineers have now developed a pentagonal concentrator mirror. They are combining this with a low-cost linear drive and new control software. Five of these heliostats are now being mounted and tested on test platforms at Jülich.

    “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...

    Water wheel with rotating blades

    A newly developed water wheel is now able to generate power at locations where it had previously been technically almost impossible. The machine works fully submerged without weirs at a low flow speed and can move forwards and backwards. As a result, it can be used in rivers and also in tidal currents. A prototype has successfully passed the laboratory tests. At the moment, developers at the University of Siegen are optimising and testing the water wheel in field conditions.  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.

    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...

    Reducing energy use from waste treatment

    Residual household waste lands in the grey waste container. It is either thermally exploited in a waste incineration plant, or it is taken to a plant for mechanicalbiological waste treatment. Here, the waste is sorted: Energy-rich parts are used for energy, while metals are recycled. The residues are treated in rotting boxes before disposal on landfills. The exhaust air from the process has to be purified. This takes up almost two-thirds of the energy consumption of waste treatment plants. Researchers, in collaboration with their project partners, have developed a more efficient method.  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...
