Tracking down corrosion

Corrosion can affect the performance of water-bearing heating or cooling systems, and even cripple them entirely. In a research project, this problem is now being examined more closely. An online survey developed for this purpose targets planners and operators. In a subsequent field test, the researchers aim to identify corrosion phenomena in a number of buildings, and implement exemplary remedial measures. They are still looking for suitable reference buildings.  more...

Solar houses scientifically evaluated

With more than 1,700 buildings realised, solar active houses are no longer a marginal phenomenon. However, what has been lacking until now is a scientific evaluation of this heat supply concept. For this reason, researchers have measured nine solar houses over several heating seasons. Project manager Gerhard Stryi-Hipp has now presented the interim results at the OTTI Symposium on “Thermal Solar Energy”.  more...

Steel beats copper

The so-called embossing stretch forming process is an established method used in the manufacture of radiators. Researchers have now adapted this process for the production of solar absorbers. Instead of using expensive copper, this method also enables steel and aluminium to be processed in large numbers and with flexible lengths. An adapted channel design compensates for the lower thermal conductivity of steel. This enables them to achieve the same thermal efficiency as conventional absorbers – and also save money.  more...

Standardised feed in of solar heat

Solar thermal systems are very suitable for retrofitting into existing buildings. However, a lack of standardisation exists when coupling the system to a district heating network. Viessmann and the Technical University of Dresden are therefore developing suggestions for future standardisation. This should help to reduce the planning effort required and save costs through unification of the various circuit variants.  more...

Series production of superconductors starts

The end of the research project marks the beginning of mass production: Theva aims to develop a mass market for superconductors with its new production facility. The manufacturer wants to provide a resistance-free conductor that can be quickly adapted to different application areas. Until now the applications have been limited to niche uses.  more...

Superlubricity reduces friction

The forces of friction play a central role in vehicles. They inevitably lead to higher fuel consumption and wear in and on all moving parts. Researchers are therefore searching for ways to keep the forces of friction as low as possible. One area of research is diamond-like carbon coatings (DLC). In an interview, Dr Johann Schnagl, Project Manager in the BMW Group and Professor Dr Michael Moseler from Fraunhofer IWM explained this area of research.  more...

Biomass in coal-fired power plants can improve carbon footprint

Using simulations for fuel flexibility, researchers hope to uncover the true extent of potential improvement to the carbon footprint of existing power stations. One option that exists is to add biomass to coal in the form of woodchips. Though at higher rates of co-combustion in particular, electrical power consumption in the crushing process increases enormously. This can be reduced with the proper pretreatment.  more...

Thermochemical storage systems for continuous load

Through the “Thermochemical energy storage unit for thermal power plants and industrial heat” project (TcET), researchers at TU Munich hope to increase the flexibility of fossil fuel power plants. The trick in all of this: If no or a reduced volume of electrical power is required, the plant does not power down. The surplus energy rather is temporarily stored in thermochemical storage systems.  more...

Virtually linking mini-CHP systems

Linked decentralised combined heat and power plants (CHP) and electric loads will be able to participate in the electricity market in the future by forming a regional and virtual power plant. This will compensate for power fluctuations and create more flexibility while being economic and efficient. The research association ‘Thermal and electric CHP linking’, coordinated by TU Dresden, presented their results.  more...

Increased range, reduced costs

One million electric vehicles by 2020 – that is the declared goal of the German Federal Government. However, existing battery systems are not suitable enough for everyday use. In the joint DriveBattery2015 project, developers are therefore designing a new control and interconnection concept. Their aims: to increase the range, reduce costs and make electric cars more reliable. The first phase of the DriveBattery project has now come to an end – time for an interim balance.  more...
