Study investigates potential of bio and solar energy
The German government has set the target of covering 14 per cent of the heat market from renewable energy sources by 2020. The BINE Projektinfo brochure “Making district heating renewable” (13/2014) describes the potential makeup of a district heating supply transformation.

Researchers have investigated the energy sources most suitable in this regard from a technical and scientific perspective. Citing results from model regions and best practice examples, the researchers have developed strategies for the future.
In the “Transformation strategies for district heating supply” study, the researchers looked at the potential effects of integrating wood-origin biomass, biogas and biomethane as well as solar thermal and geothermal energy on the efficiency of heating networks.
Findings included: Many renewable energy sources and low temperature waste heat in combination with heat pumps were found to reach their capacity limits at supply temperatures greatly above 100 °C. In nine existing networks investigated, biomass and geothermal energy were found to be the renewable energy sources accounting for the greatest share of heat generation.
For the model regions of Ulm and Jena, the researchers developed strategies for the transformation of district heating supply. With in excess of 50 per cent of heat generation covered by renewable resources, Ulm has already become a forerunner is this area. In Jena, this value could be achieved by 2030 if the total heating requirement is reduced due to renovation works. The Stadtwerke Jena-Pößneck municipal utility companies are currently reviewing new options for the city’s energy supply in the “Integrated energy and heating concept 2050”.
The researchers have also developed a decision tree for operators of district heating networks. Operators can use this tool to investigate how they can increase the proportion of renewable energy sources in their supply systems. The "Transformation strategies for district heating supply" study was conducted by the IFEU institute, GEF Ingenieur AG and the AGFW (German energy efficiency association).

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
