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...

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...

Stable grid with 100 per cent green electricity

In a power grid, the energy provided must always be equal to the power demanded. Only then can frequency and voltage remain stable. Ensuring this is the task of grid operators. But when volatile — meaning not arbitrarily adjustable — energy sources are the main sources of electrical energy, grid operators face a challenge.  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...

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...

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...

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...
