    Large-scale solar thermal systems in long-term testing

    Can solar thermal plants achieve a consistently high yield for more than ten years? In order to answer these and other questions, scientists from Düsseldorf University of Applied Sciences have surveyed the operators of 76 large-scale solar thermal plants and monitored ten of these systems for one year. All systems were funded at the turn of the millennium as part of the Solarthermie2000(plus) programme.  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...

    New energy-efficient school building in the spotlight

    The new, energy-optimised building for the Willibald Gluck Secondary School in Neumarkt (Upper Palatinate, Germany) utilises solar energy and near-surface geothermal energy. The first year in regular operation has provided good values: the heat pumps are contributing their planned share to the heat generation and the photovoltaic systems cover 35 per cent of the electricity consumed for the building operation and use. Storing the PV electricity in a vanadium redox flow battery has not, however, increased the proportion of self-consumed electricity during the first year of operation. The operation of the ventilation systems also provides potential for optimisation.  more...

    Competition building becomes a university laboratory

    A team of students from Berlin University of the Arts and Technische Universität Berlin designed a net energy plus building for the Solar Decathlon Europe 2014 competition. The house is now being rebuilt on the Charlottenburg campus. It is intended for use as a seminar room and laboratory in the future. After minor modifications and with additional measurement technology, the students can learn about energy monitoring with a real building as an example.  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.

    School: Refurbished from Plattenbau to Passive House

    The school building belonging to Max Steenbeck Secondary School in Cottbus was old and the extent of the building damage made it impossible to carry out renovation work during the school's ongoing operation. This meant that the school had to move. To this end, an old system-built “Plattenbau” school with an auditorium and gymnasium had to be first of all comprehensively modernised. The City of Cottbus placed high demands in terms of the energy consumption, comfort and operating costs.  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...
     

    Solar process heat

    Around three-quarters of the final energy consumption in the industrial sector in Germany is caused by process and space heating. Solar heat can be used in many different ways in the low-temperature operations in particular, as well as in the commercial, trade and services sectors. International studies confirm the global potential for this technology.  more...
     

    Web portal for energy-optimised buildings and districts

    The website of the ENERGIEWENDEBAUEN research initiative is now online. The German Federal Ministry for Economic Affairs and Energy is bundling its long-standing subsidy measures entitled Energy Optimized Building, Energy-Efficient City and Energy-Efficient Heating and Cooling Networks, and also research on thermal energy storage and low-temperature solar thermal energy systems in the redesigned research initiative. They are being brought together under one umbrella initiative.  more...
