Heating and cooling with waste heat from industry

08.07.2015

Heating and cooling in the future will utilise energy gained from waste heat which will be distributed at low temperature using district heating and cooling networks. It will thus make use of the heat wasted by cooling systems in supermarkets and fruit storage facilities which up to now has simply been released untapped into the atmosphere.

South Tyrol’s EURAC Institute for Renewable Energy is exploring this new technology in the “FLEXYNETS” project which is financed to the tune of two million euros by the European research programme “Horizon 2020”. Yesterday, on the 7th July, the project partners finally met at EURAC to set things in motion.


At present district heating grids run via high temperatures of around 90 °C. To heat individual buildings, the networks have to connect to sizeable thermal plants, such as block thermal plants or waste incinerating plants. The technology which will now be researched by the South Tyrol EURAC Institute for Renewable Energy on the other hand runs at temperatures between 10 and 20°C.

This means that the district heating grids can be supplied with energy from sources running at much lower temperatures than previously. “We are working on developing district heating and cooling systems for tomorrow. We do not want to replace existing systems, but rather are seeking to integrate them into new concepts.

Space heating, generated for example from a waste incinerating plant, is intended to be supplemented by heat generated in various everyday processes and which is currently wasted,” explained Roberto Fedrizzi, scientist at the EURAC Institute for Renewable Energy and Director of the FLEXYNETS project. “By using low temperatures when distributing heat, we reduce the present huge heat loss in the underground distribution pipelines, which will make the whole grid much more efficient in the future,” said Fedrizzi.

According to the experts, the energy consumption for heating and hot water could be reduced by 80%, and for cooling buildings by 40%. Across Europe, this would amount to a reduction of 5 million tonnes of CO2 emissions by 2030.

The first phase of the three-year project will concentrate on developing the technology. There will then follow a test phase which is due to begin in summer 2016.

“For this first phase we will set up a laboratory in the Technology Park in Bozen-Bolzano simulating a small-scale district heating and cooling network. This will enable us to simulate and test different control strategies as well as operating scenarios,” added Roberto Fedrizzi.

The project’s third phase is dedicated to devising incentive measures for exploiting waste heat and strategies for integrating this new technology into already existing municipal systems. For this purpose, two working groups will be set up which will include district heating experts as well as representatives of the municipalities such as energy managers.

The FLEXYNETS Project will be managed by EURAC. Project partners from the whole of Europe attended the initial meeting in Bozen-Bolzano on July 7th and 8th: the University of Stuttgart, along with agencies and companies specialising in district heating systems from Italy, Spain, Germany and Denmark.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
