Calculating and comparing refurbishment costs

Maintaining and refurbishing municipal properties to improve their energy efficiency costs money that in many cases is lacking. A new software program now makes it possible to calculate different refurbishment scenarios for existing municipal buildings and to compare them in detail. This helps to strategically plan the investment in cities and local communities.  more...

Doubling the power density with metal fibres

Zeolite can adsorb significant amounts of water vapour, thereby releasing latent heat. This property is used among others in gas adsorption heat pumps. Scientists have found a way to increase the heat transfer area, thereby increasing the power density of the heat pump module. An initial sorption module with an innovative zeolite coating for the heat exchanger is now available.  more...

Testing rotor blades cost-effectively

The longer the rotor blades used on wind turbines, the greater the forces acting on them. The requirements for the components rise – and with them the demands made on the testing methods. On the one hand it is important to construct the blades as durably as possible. On the other hand, however, they also need to be manufactured so that they are as cost-effective and as light as possible. If a compromise is found, this still needs to be checked in a verifiable way: on the computer and in practice.  more...

SpeedColl: Allowing collectors to age more quickly

Whether in maritime, arid or alpine regions, solar collectors must perform flawlessly for years. But to what extent do high UV radiation, salty and humid air take their toll on the collectors? In order to find out, researchers at Fraunhofer ISE and Stuttgart University exposed solar collectors to the wind and weather at six locations. The result: The collectors and the components are more durable than previously thought. However, that makes it even more difficult to make comparisons.  more...

Once coated, everything runs smoothly

The wear and energy consumption of machinery increase dramatically if the machines are not optimally lubricated. In many cases, however, ideal lubrication is impossible, for example, in free-running motorcycle chains or agricultural machinery. To meet these operating conditions, researchers are therefore developing new coatings, and lubricants adapted to them, as part of the CHEOPS3 project. The twelve project partners from industry and science want to achieve long-term protection against wear, even with minimal lubrication and dry friction, so as to increase the efficiency of machines.  more...

Neckarpark Stuttgart: Heat from waste water

Sewage stinks and is filthy – but it is suitable for supplying heating and cooling to buildings. In Stuttgart’s new Neckarpark urban district, the energy in the municipal waste water is extracted by means of a trough heat exchanger in the sewage channel and utilised via a low-temperature local heating network. This provides the basis of the energy concept for the new district, which is being created with highly energy-efficient buildings on the brownfield site belonging to the former Bad Cannstatt railway freight depot.  more...

AmpaCity receives innovation award

Since the spring of 2014, a superconducting cable helps to ensure that the lights stay on in the centre of Essen. It transmits up to 40 megawatts of electricity – almost without loss. With AmpaCity, researchers from science and the electricity industry are demonstrating how high voltage lines and transformer substations could be eliminated in urban areas. On 20 January 2016, the project, which is funded by the German Federal Ministry for Economic Affairs and Energy, was conferred the German Innovation Prize for Climate and the Environment.  more...

Energy centre supplies Giessen University Hospital

Giessen’s municipal utility company and University Hospital have jointly constructed the first energy centre to be integrated into a local heating and cooling network. The newly developed combined cooling, heating and power system ensures an uninterrupted supply to the hospital. It saves 21.7 % of the primary energy and 33.6 % of the CO2 emissions.  more...

Lime storage systems: Cheap, efficient and sustainable

At the German Aerospace Centre (DLR), researchers are using lime as a storage medium in a specially developed heat storage system. This enables heat to be stored in the form of a reversible reaction. Such storage systems can help large amounts of energy to be used more efficiently in industrial processes and households. The new plant has now been put into operation.  more...

Future heating supply designed

Over the past thirty years, the population of Duisburg has fallen by more than a fifth, and the heating requirement has also reduced. A team of experts has investigated how the municipal utility company can adapt the heating supply in accordance with these developments by 2050. A main recommendation: The interconnection of two district heating networks would increase the primary energy efficiency and cut costs, mainly because industrial waste heat could be better utilised.
