    How electric vehicles can be of use to the grid

    The batteries in electric vehicles can store surplus energy from the electricity grid. By the same token, they can feed back electrical energy to the grid at times of high demand for electricity. As part of the NET-INES project, scientists are investigating different charging and discharging strategies as well as the opportunities to market this service. For this purpose, they surveyed more than 600 vehicle owners.  more...
     

    Thermochemical storage systems for continuous load

    Through the “Thermochemical energy storage unit for thermal power plants and industrial heat” project (TcET), researchers at TU Munich hope to increase the flexibility of fossil fuel power plants. The trick in all of this: If no or a reduced volume of electrical power is required, the plant does not power down. The surplus energy rather is temporarily stored in thermochemical storage systems.  more...
     

    Vacuum tank stores heat

    An efficient long-term heat storage tank boosts the shares of fraction of solar thermal energy systems in buildings. Staff at Bavarian Center for Applied Energy Research and at steel and metal engineering company Hummelsberger have developed a storage system that minimises thermal losses and optimises temperature stratification. A vacuum between the inner and outer tank combined with a perlite powder filling reduces the thermal conductivity of the storage tank shell.  more...
     

    Making district heating renewable

    Three research teams have investigated how the proportion of renewable energies can be increased in district heating networks. Custom strategies were developed in this respect for the model regions Jena and Ulm. The key lay in identifying the appropriate renewable energy sources and in understanding the potential these exhibit and the effect their inclusion would have on the efficiency of the networks. The project also comprises a survey of existing heat networks with best practice analyses.  more...
     

    Prospects for pumped storage power plants

    Pumped storage power plants make an important contribution to securing energy supplies and help to integrate renewable energies into the electricity grid in a profitable manner. However, it is precisely the grid feed-in of wind and solar power that is threatening the current business model for the plants. A study is therefore investigating how their economic viability and the investment environment can be improved through cooperation between Germany, Austria and Switzerland (the DACH countries).  more...
     

    Flexible deployment of heat storage systems

    Those retrofitting heat storage systems in buildings often come up against their limits. Large-volume storage tanks often do not pass through standard doors. Together with Consolar, which manufactures solar thermal systems, scientists at the Institute for Thermodynamics and Thermal Engineering at the University of Stuttgart are therefore developing a storage system that consists of several modules and can be assembled on site. The modular storage system will be installed in an apartment building and tested in practice in autumn.  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...
     

    Stabilising the grid with wind power

    In future it is intended that photovoltaic systems and wind farms contribute more to the stability of the electricity grid. They could then replace some of the fossil fuel capacities that until now have had to be used for the sole purpose of balancing out frequency variations. In a study, methods have been developed that can be used for intermittent renewable energies when bidding to supply control reserve as part of regular tendering periods.  more...

    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...
