    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...

    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...

    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.

    Communication concept for deep geothermal energy

    Technical innovations can only be successful if they are supported by the public. Plants for utilising renewable energies are also dependent on this backing. Early and comprehensive communication with the public is therefore indispensable. For deep geothermal energy, scientists have analysed public perceptions and have developed a communication concept. It offers operators and authorities a wealth of ideas and support for active and transparent public relations.  more...

    Learning and working in an energy-plus school

    Uhland School in Stuttgart, which dates back to the 1950s, no longer accorded with today's structural and energetic standards. The renovation work is now almost complete and the City of Stuttgart is getting its first energy-plus school. A photovoltaic system on the roof and façade of the building covers the electricity requirement.  more...
     

    Video inspection tool brings light into the darkness

    Scientists in Karlsruhe are developing a camera inspection system for deep geothermal drilling holes. The device must be able to withstand strong pressure and high temperatures. This presents a particular challenge for the electronic components. A first draft design for the system has now been completed.  more...

    Developing robust pumps for geothermal energy

    Systems for using deep geothermal energy need special pump systems. These are up to 36 meters long and weigh eight tonnes. They must be able to withstand high temperatures and high flow rates, as well as mineralrich water. Pumps for geothermal energy have been tested during several field tests and on the largest high-temperature test loop in the world, and have been significantly improved. The prototypes already fulfil the development goals to a large degree. By 2017, key components will have been further developed ready for serial production.  more...

    Excellent climate for ancient manuscripts

    The new Central Library combines the book collections that were previously spread across several locations. Luitpoldhaus, which is located in a listed ensemble of buildings in Nuremberg’s old town, has been rebuilt and expanded. The project aim of undercutting the requirements of EnEV 2007 for new-build schemes by at least 30% has been exceeded. However, the high demands placed on the indoor environment for archiving and exhibiting medieval manuscripts made the task extremely tricky.  more...
     

    Researching the natural seismicity

    The Upper Rhine Graben (Rhine Rift Valley) has geothermally usable hot water resources at an attainable depth. This geological feature is caused by the fact that the deep rock strata has remained in motion to this day. This repeatedly causes slight natural earthquakes in the region. In rare cases, however, human activities, such as the construction and operation of geothermal plants, can also trigger shocks. This effect is called induced seismicity. Prior to constructing a geothermal plant in Groß-Gerau, researchers have therefore been measuring the natural seismicity in the region using a dense monitoring network.  more...

    Electric impulses fragment hard rock

    Until now, roller bits have been used for drilling in deep-lying rock. These only advance slowly through crystalline formations and wear out quickly. That makes drilling measures more expensive and is particularly an economic problem for deep geothermal projects. Researchers in Dresden (Germany) are therefore developing an alternative drilling method for hard rock where a high-voltage impulse fragments the rock. Up to 30 % lower drilling costs are possible.  more...
