    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...

    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...

    Testing towers and foundations

    Manufacturers are offering ever larger and more powerful wind turbines for utilising wind power. As the wind turbine sizes increase, the wind and weather take an increasing toil on the structures and turbine components. Hanover University’s Test Center Support Structures opened in 2014 to enable the components used for the tower and foundations to be tested and optimised in advance.  more...

    Local heating links newbuild with existing district

    By means of a district energy concept, researchers in Ludwigsburg are combining the advantages of ambitious building concepts and refurbishment measures with energy efficient heat supply. The heat required for the Sonnenberg development area is generated in winter using a brine/water heat pump in combination with a combined heat and power plant. The local heating network and its extension into the adjacent existing district of Grünbühl provide the post-war housing estate, which is in need of refurbishment, with not just greater living comfort but also energy efficiency benefits and cost savings.  more...

    Heating with gas adsorption heat pumps

    Condensing boiler technology has long been considered the most energy-saving technology for heating single- and multi-family homes with gas. Its systematic further development is now provided by adsorption heating devices. They combine condensing boiler technology with a zeolite/water-based thermal heat pump module. This uses geothermal energy or solar energy and reduces the fuel consumption by more than 20 per cent relative to condensing boiler technology.   more...

    Taking user behaviour into account with refurbishments

    With the refurbishment of a residential neighbourhood in Karlsruhe everything was done correctly in theory. Nevertheless, the consumption values measured in three investigated buildings are up to 25 per cent higher than the requirement values calculated prior to the refurbishment. Scientists at the E.ON Energy Research Centre at RWTH Aachen University are investigating the causes of this so-called “rebound effect”.  more...

    Efficient production of monocrystalline semiconductors

    A Freiberg-based semiconductor manufacturer has now developed a new process that enables up to nine crystals to be grown simultaneously in parallel. This reduces the specific energy consumption for the production by two thirds. The new technological principle can be applied to growing other semiconductor substrates.  more...

    Combining compost and biogas

    A new method improves the energy balance and processing capacity of composting plants. With the usual composting process, considerable energy is consumed to provide the required mechanical ventilation. In the new method, the liquid organic components of the organic waste are separated in advance and are used for producing biogas. This enables energy to be generated in the plants. For the project, a new biofilm digester has been designed which provides cost advantages relative to other digestion processes.  more...

    Fresh air for new school buildings

    A school where you feel at home that at the same time consumes little energy during operation – that is the Niederheide primary school in Hohen Neuendorf. A ventilation system which combines mechanical and natural ventilation via the windows ensures a good air quality and a pleasant indoor environment in the classrooms. It is the first school in Germany to receive the Gold Medal for Sustainable Construction. It was certified in accordance with the Sustainable Construction Assessment System (BNB) developed by the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB).  more...

    Fast-track testing of nacelles

    In Bremerhaven, a test rig is being developed that can test complete wind turbine nacelles in the multi-megawatt class. Unprecedented: a load transmission system mechanically simulates the wind loads occurring in the field. The researchers are investigating the electrical components using a simulated electricity grid. Laboratory tests are also providing information on how wind turbine concepts can be improved. With these properties, the test rig has the world’s most powerful grid simulation system.  more...
