    Application prospects for hydrogen storage systems

    Can large-scale hydrogen storage systems help pave the way for renewable energy? Scientists from several research institutes investigated the technical and economic requirements for this in the PlanDelyKaD research project. The research focused on hydrogen electrolysis and gas storage in salt caverns. The study also revealed the method’s potential on the market.  more...

    Removable interior insulation for historic monuments

    Insulating the interior of listed historic buildings can conflict with building preservation orders: room surfaces are often invaluable witnesses of the past. These surfaces can come loose when the glued insulating wall panels are removed. Together with industrial partners, researchers at the Fraunhofer Institute for Building Physics IBP are developing safely detachable interior insulation systems for a building of the Benediktbeuern monastery. Further partners can join the project until August.  more...

    Concept for refurbishment with an expansion of living space

    Last Monday, students at the Frankfurt University of Applied Sciences completed the construction of their OnTop building prototype, and celebrated this with an event at the site. Previously, the building on the premises of the prefabricated house manufacturers Bien-Zenker had been constructed on a trial basis before it will enter the international university competition Solar Decathlon Europe 2014 in Versailles, France, later this month. With this concept, the team from Frankfurt am Main aims to combine the redevelopment of urban living space with storey additions.  more...

    Modular roof pavilion with solar active facade

    Last Friday was the day: Berlin students celebrated the construction of their roof pavilion Rooftop. This building concept allows existing town houses to be upgraded with energy-plus housing units. Several night shifts were necessary to install the hinged solar facade on schedule. Later this month, the prototype building will enter the international university competition Solar Decathlon Europe 2014 in Versailles, France.  more...

    Compact grid nodes for low-loss electricity transmission

    The development of compact switching points for DC transmission solves a problem caused by the grid expansion: the grid nodes and feed-in systems are becoming smaller and can thus be installed more conveniently in urban areas and on platforms for offshore wind farms. Siemens’ development manager Denis Imamovic is today presenting the latest results of the research project at the Berliner Energietage conference.  more...

    Rotating receiver heats up ceramic beads

    Until now, tube receivers have been used in solar tower power plants to absorb the concentrated solar rays and convert them into heat. The German Aerospace Centre (DLR) is now pursuing a new approach. In a rotating receiver, ceramic particles are evenly heated up to 1,000 degrees Celsius. The advantage of this is that the beads also act as a storage medium. The centrifugal receiver at the Jülich solar tower is scheduled to enter operation from mid-2015.  more...

    “Wind energy has excellent prospects inland”

    One of the highest wind measurement masts in Europe has been standing on top of a wooded hill near Kassel since 2011. The mast is being used to investigate the wind layers between 100 and 200 metres in height and the influence of forest cover and terrain inclinations on the wind profile and generation of turbulence. The measured values, which are obtained using conventional sensors on the mast, are also used to validate and further develop laser-based LiDAR methods. In the interview, Paul Kühn, Group Manager for Onshore Site Assessment at the Fraunhofer Institute for Wind Energy and Energy System Technology IWES, talks about the project’s initial results and future prospects.  more...

    Accelerated ageing of collectors

    In the desert, in the Alps and along the coast: at these locations, solar collectors are exposed to a combination of high UV radiation along with salty and humid air. That stresses the components in solar thermal systems and makes them age faster. Until now, however, this has not been adequately investigated. For this reason, Fraunhofer ISE is now developing tests to accelerate the ageing of collectors in different climate conditions. The preliminary findings are being provided by the SpeedColl project.  more...

    “Secure provision of data centres with renewable energies”

    The RenewIT project is researching how data centres can make greater use of renewable energies. That is an important goal for project partner Thorsten Urbaneck, who is a private lecturer at Chemnitz University of Technology. This is because it is estimated that data centres consume two per cent of the electricity used in Europe – and the trend is increasing.  more...

    Storing summer heat until winter

    In the SolSpaces project, researchers from the Institute for Thermodynamics and Thermal Engineering at the University of Stuttgart are developing a new heating concept for compact residential buildings. This includes a collector system with a thermochemical storage system that can store the solar thermal energy from summer until winter. The scientific monitoring has begun.  more...
