    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...

    Does the energy transition need energy storage systems?

    The fact that energy storage systems have a role to play in the energy transition is hardly controversial. But statements about the actual demand, competitive solutions and application scenarios sometimes contradict each other. The Fraunhofer institutes UMSICHT and IWES have examined studies on the topics of electricity storage systems and Power-to-Gas.  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...
     

    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...

    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...

    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...

    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...
