    Material loading in flexible power plants

    The conditions for operating conventional coal and natural gas power plants are changing considerably as a result of their combination with renewable energies. In future they will run more frequently under partial loads, have considerably more start-up and shut-down cycles, and the components will be subjected to greater and more diverse loads. Scientists have investigated the thermal and mechanical loads on thick-walled components in power plants under the new conditions. At any given safety level, the aim is to more precisely calculate the stability of components in regard to their damage and thus economically optimise their deployment times.  more...

    From air base to residential neighbourhood

    A new residential district is being built on the site of a former air base in Oldenburg. In addition to new buildings, some of the former barracks buildings will be preserved and converted into residential buildings. A new infrastructure concept is planned that will couple the electricity, heating/cooling and electromobility sectors and integrate them into a cross-sectoral supply network. In addition, the project partners are developing a digital service platform to provide intelligent load and procurement management at the district level.  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...
     

    Night-time electricity from solar thermal power plants

    Together with the industrial partner Linde AG, researchers from the German Aerospace Center have further developed a latent heat storage system based on nitrate salts. In combination with a cascade of sensible heat storage units, the goal is to maintain the electricity production of solar thermal power plants at night and at times with low solar irradiation. To this end, the scientists have developed a storage system that can also be used for conventional steam power plants and industrial processes.  more...

    German-French geothermal power plant completed

    In the Upper Rhine Graben, natural geological thermal deposits can be tapped at comparatively low depths with bore wells. In a Franco-German research project in Alsace, scientists have been researching the process of utilising heat from crystalline rock for years, whereby they have optimised the concept and technology. At the site of the research facility, two power companies opened a new commercial power plant in 2016. The electricity is fed into the French grid. In Germany, around 95% of geothermal resources are also found in deep rock and 5% in natural thermal water layers.  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...

    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...
     

    The future of power plants

    The "Flexible Energy Conversion" research network was founded in Berlin at the end of February 2017. Here, researchers and developers from the conventional power plant technology and solar thermal power plant fields will jointly develop future strategies. The goals: To increase the flexibility of large-scale power plants, develop new large-scale storage systems, extensively research the use of hydrogen in power plant processes and in particular optimise the economic efficiency of solar power plants.  more...
     

    The sun shines with the click of a mouse

    Synlight is the name of the world's largest artificial sun, which is situated in Jülich near Aachen. Its bundled light is 10,000 times stronger than the sun. With this energy, researchers want to test solar thermal components in order to produce hydrogen directly – without having to use electrolysis. Last week, the research facility was officially inaugurated.  more...
