    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...

    New approaches to supplying domestic energy

    Fuel cells have unique abilities: in contrast to other co-generation (CHP) plants, they directly convert the chemically bound energy of fuel sources such as hydrogen or natural gas without using a flame. If they are deployed in heating devices, they generate electricity and heat efficiently. Indeed, they are considerably more efficient than combining conventional electricity generation and condensing boilers.  more...

    Generating electricity and heat from lean gas

    Large volumes of carbon (coke) are used for the melting process in the cupola furnace, whereby a combustible process gas is formed as a by-product. This so-called cupola furnace gas has a low heating value and has previously been completely combusted for generating the hot blast in the cupola furnace's recuperator. However, in this process only around 35 % of the contained energy is used thermally. Now it is possible to utilise the remaining 65 % of the chemically bound energy that was previously not used in most foundries: a modified biogas combined heat and power plant runs with cupola furnace gas (CFG) from the melting furnace.  more...

    The electricity grid as a marketplace

    In future, electricity grids will have to transport large quantities of electricity from renewable energy sources fed centrally and decentrally. Plus, we need greater reserves, storage facilities and flexibility in the electricity market due to the fluctuating supply. In the "Modellstadt Mannheim" project, a virtual energy marketplace is being developed for energy generators, consumers and grid operators. Customers can see the source and price of their electricity and influence them directly via the timing and extent of their consumption and the delivery from their own generation systems. This approach also includes gas, water and district heating.  more...
