Thermal storage systems brought into shape

Thermal storage systems that utilise zeolite are still very rare. In a research project, scientists have investigated aluminosilicates for their practical use in thermal storage systems. They have succeeded in significantly improving the energy density, cycle resistance and thermal performance. The research has led to the development of a thermochemical storage system for a CHP power plant.  more...

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...

World record for both sides-contacted silicon solar cells

With a new process for backside contacting, researchers at the Fraunhofer Institute for Solar Energy Systems ISE have set a new record for both sides-contacted silicon solar cells. The scientists achieved an efficiency of 25.1 per cent with an ultra-thin, tunnel oxide back contact. This is applied over the entire surface and does not require complicated processing steps for texturing the cell’s rear side.  more...
150908 1 Rotorblattpruefung 90-Meter-Halle IWES

Rotor blade, nacelle and foundation put to the test

Whether on land or in the sea, wind turbines are getting bigger and the towers higher. All components undergo various preliminary tests, in order to ensure that they can withstand the strains that wind and weather place on them. In recent years, large test facilities have become available in Germany, in which complete rotor blades, nacelles, and foundations are tested. On 21 October 2015, centres will present their supply ranges at a workshop for experts.  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...

Energy thanks to lunar power

Researchers are developing a new approach for generating energy from tidal currents. Here they are combining a semi-submerged platform with several small-sized instream turbines. This means that the tidal power plant requires less maintenance than is usually required. However, in order to achieve the highest possible energy yields it requires strong water currents. Canada’s Bay of Fundy has an exceptionally high tidal range exceeding 15 metres. This is where it is planned to build the hydropower plant so that it can provide the first electricity in 2017.  more...

Nickel alloys allow for higher temperatures inside power plants

Higher temperature differences can increase the efficiency of power plants, and thus lower CO2 emissions. The lower limit is determined by the outside or ambient temperature, and the upper limit depends on material properties. As part of the research project HWT II (high-temperature material test track II), experts examined the behaviour of thick-walled pipe and fitting components during the required flexible operation at temperatures of up to 725 °C.  more...
150706 1 Elektrolyseeinheit Siemens AG

World’s largest electrolysis plant inaugurated

The world's largest electrolysis plant of its kind has been created in Energiepark Mainz. It has an electrical connected load of six megawatts and can produce up to 1,000 cubic metres of hydrogen per hour from renewably generated electricity. The hydrogen produced can be stored on site, transported in tanks or fed into the natural gas network where it can be used at a later point for generating electricity or heat. The plant has now been officially inaugurated.  more...

Preparing the electricity grid for electric vehicles and heat pumps

The electricity grids in Germany have to be expanded to cope with decentralised generators and increasingly more large-scale loads. For grid operators it is therefore important to gain an overview of the necessary measures and their effectiveness even before installing new operating resources. Special simulation and planning tools are suitable for this. As part of the Novel E-Mobility Grid (NEMO) research project, scientists at the Fraunhofer Institute for Solar Energy Systems ISE have developed a software programme that can help to analyse and plan power grids.  more...
