Integrating more renewable energy in district heating networks

11.12.2014

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).

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
