    Energy storage systems in 2030

    What role will functional storage systems play in the energy supply system of the future? Which system infrastructure can economically secure a reliable energy supply in 2030? And what measures must the government take so that this system infrastructure can prevail on the market? Scientists at the Research Center for Energy Economics (FfE) are trying to get to the bottom of these questions with an ongoing study. The results are now available.  more...
     

    Energy centre supplies Giessen University Hospital

    Giessen’s municipal utility company and University Hospital have jointly constructed the first energy centre to be integrated into a local heating and cooling network. The newly developed combined cooling, heating and power system ensures an uninterrupted supply to the hospital. It saves 21.7 % of the primary energy and 33.6 % of the CO2 emissions.  more...

    Net Zero Energy and Net Energy Plus Buildings

    Buildings generally have the potential and infrastructure to generate the energy required by them on site. This provides the principle behind net zero-energy or net energy-plus buildings, whose numbers are steadily increasing around the world and especially in Germany. They have names like “energy-plus house”, “zero emissions house”, “efficiency house plus”, “activated-plus house” or “solar active house” and, internationally, “net zero-energy building”, “carbon neutral home”, “EQuilibrium™ House” and “Bâtiment à énergie positive”.  more...

    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...
     

    Research funding for the energy turnaround increasing

    Energy research contributes towards the development of the processes and technologies necessary for achieving the goals of the energy turnaround. The German government has been continuously increasing funding for energy research since 2006. In 2013 alone, it spent 100 million euros more on this than in the prior year. This reinforced above all the research areas of energy efficiency and renewable energy sources. It provided just under 300 million euros for each of these subjects.  more...

    Researching in the global network

    International research collaborations are becoming increasingly important. Germany is involved in a variety of ways in international energy research. An important pillar in this regard is its involvement in the International Energy Agency (IEA). Germany is a founding member of this organisation. An IEA field of activity particularly relevant to energy research is its energy technology network.  more...

    Intelligently controlling CHP plants

    If the wind only blows weakly and the sun does not shine much, the amount of electrical energy fed into the grid drops. The electricity prices then increase on the European Power Energy Exchange (EEX) in Paris. This is when around 800 mini-CHP plants receive the signal to increase their electricity production. The control room belonging to the Lichtblick energy provider controls the CHP plants distributed across Germany, which are linked to one another by radio contact.  more...
     

    On route to a low-energy urban district

    Redeveloping an urban district represents not just an architectural challenge - the tenants behind the facades must also be taken into account. Those involved in the "Weingarten 2020" research project are aiming to meet both demands. With the involvement of the Fraunhofer Institute for Solar Energy Systems ISE, they have created the first passive high-rise building in a district of Freiburg. A further important milestone was the optimisation of the energy supplies.  more...
     

    Using solar roofs twice over

    Instead of screwing various module and collector types for solar power and solar heat on the roof, an obvious idea would be to use a hybrid collector that can do both and which creates a uniform appearance. In addition to generating photovoltaic electricity, which only utilises 15-20 % of the incident solar radiation, a so-called PVT collector can use the remaining radiation energy for generating heat. Researchers are working on optimising the output and production of these systems.  more...
     

    Cooling with heat

    The economic and ecological success of many CHP plants, district heating networks and large-scale solar power systems very much depends on the utilisation of heat outside of the heating periods. An increasingly interesting market for low-temperature heat is cooling and air-conditioning buildings as well as generating process cooling energy with thermally driven chillers. Scientists from Berlin and Bavaria have developed a new generation of particularly compact, efficient absorption chillers with small capacities for cooling and heating operations.  more...
