    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...

    Stable grid with 100 per cent green electricity

    In a power grid, the energy provided must always be equal to the power demanded. Only then can frequency and voltage remain stable. Ensuring this is the task of grid operators. But when volatile — meaning not arbitrarily adjustable — energy sources are the main sources of electrical energy, grid operators face a challenge.  more...
     

    Energy research on course to delivering the energy transition

    The German federal government recently published the National Action Plan on Energy Efficiency. The concept is specifically aimed at winning over all actors in society in achieving greater energy efficiency. A few days later, the German Federal Ministry for Economic Affairs and Energy announced its research funding for the German federal government’s 6th Energy Research Programme. In the BINE interview, Dr Rodoula Tryfonidou from the responsible department in the German Federal Ministry for Economic Affairs and Energy talks about the contribution made by energy research in bringing about the Energiewende – Germany’s energy transition.  more...
     

    Making district heating renewable

    Three research teams have investigated how the proportion of renewable energies can be increased in district heating networks. Custom strategies were developed in this respect for the model regions Jena and Ulm. The key lay in identifying the appropriate renewable energy sources and in understanding the potential these exhibit and the effect their inclusion would have on the efficiency of the networks. The project also comprises a survey of existing heat networks with best practice analyses.  more...
     

    Research funding for the energy turnaround increasing

    Energy research contributes towards the development of the processes and technologies necessary for achieving the goals of the energy turnaround. The German government has been continuously increasing funding for energy research since 2006. In 2013 alone, it spent 100 million euros more on this than in the prior year. This reinforced above all the research areas of energy efficiency and renewable energy sources. It provided just under 300 million euros for each of these subjects.  more...

    Researching in the global network

    International research collaborations are becoming increasingly important. Germany is involved in a variety of ways in international energy research. An important pillar in this regard is its involvement in the International Energy Agency (IEA). Germany is a founding member of this organisation. An IEA field of activity particularly relevant to energy research is its energy technology network.  more...

    Database shows output from renewables

    The sources of renewable energy –sun, wind, water and biomass – account for a large share of the electricity production in Germany. At the beginning of July 2014, solar energy covered the entire peak load. This is shown in the new online “Energy Charts” database at the Fraunhofer Institute for Solar Energy Systems ISE.  more...
