    Modern living in an historic urban district

    The Margaretenau residential district in Regensburg is being modernised to improve its energy efficiency. The designers are developing a solar-active and -adaptive exterior render system as a replacement for conventional thermal insulation for the facades. This should increase the solar yields and improve the thermal comfort inside the buildings. The energy supply will be provided by a new and efficient hybrid heating system consisting of cogeneration and heat pump technology.  more...
     

    When are flexible district heating systems beneficial?

    The integration of thermal storage in cogeneration plants leads to more flexibility in district heating networks because the power generation can be better adapted to the power requirements. Power-to-heat systems couple the electricity and heating sectors to utilise renewable electricity for district heating. Together with partners from science and industry, researchers at the TU Berlin have investigated when the construction of heat storage and power-to-heat systems can be economically and ecologically beneficial.  more...

    Closing security loopholes in power grids

    The way in which electricity distribution networks operate is changing considerably as a result of the energy transition. Decentralised systems are increasingly being connected via the Internet with the central control rooms of the energy providers for control purposes. The risks that can arise due to security loopholes in the information system are accordingly growing. In a guide, researchers at Bremen University of Applied Sciences show how the operational management can be secured and how the risks can be limited if measures fail.  more...
     

    Sphere storage system receives German Renewables Award

    One year ago, scientists sank a concrete sphere one hundred metres below the surface of Lake Constance. The three-metre-diameter hollow body provided a functional model for an offshore pumped storage power plant. Now they have received the “German Renewables Award 2017” for their research work. The developers at Fraunhofer IWES are already planning the next step.  more...
     

    “Solar thermal energy is becoming an integral part of district heating”

    Traditional district heating is converging with solar thermal energy: researchers and engineers presented new technologies for integrating solar thermal systems into the heating provision at the German Federal Ministry for Economic Affairs and Energy's status workshop entitled “Solar thermal energy in district heating”, which was held at the end of September in Dresden. In addition, the workshop also provided insights into current developments in Europe and worldwide.  more...
     

    Refrigerators stabilise the electricity grid

    Refrigerators that consume electricity precisely when the wind and the sun provide excess electrical energy, and which during slack periods maintain their cooling temperature without additional energy input, would greatly relieve the grid. Scientists from ZAE Bayern are investigating the costs and benefits of such a load shift together with industrial partners. For this purpose they are increasing the thermal inertia of an efficient standard refrigerator by installing latent heat storage units. The test device can thereby bridge longer standstill times.  more...
     

    Local electricity networks become flexible and resilient

    For three years, the Saarlouis municipal utility company, together with partners from science and industry, has worked on the development of what are known as resilient poly-networks. These autonomous electricity networks at the local level are designed to adapt dynamically to the respective network situation in order to ensure optimum supply. The findings were recently presented at a concluding event.  more...
     

    New low-emission marine engines

    The operation of ships causes considerable pollutant emissions. Future ship propulsion systems must therefore be more environmentally friendly. One possible way is to operate engines with natural gas rather than diesel. They have lower emissions when compared with current diesel engines without exhaust after-treatment. Researchers are developing and testing components and control instruments for this economical new generation of engines. They are aiming to reduce the engines' CO2 emissions and halve them in future.  more...
     

    Modular battery storage system supplies balancing energy

    How can large-scale battery storage systems help stabilise electricity grids and at the same time be profitable? This question is being investigated by scientists at RWTH Aachen University in collaboration with industrial partners using the large-scale M5BAT battery storage system. Using a modular and flexibly scalable batteryinverter concept they are testing the interaction of different accumulator technologies and are developing business models for decentralised storage systems in real grid operation.  more...

    Intermediate storage of renewables

    How could more renewable energies be used that also stabilise the grid? To answer this question, researchers at the MEET Battery Research Centre at Münster University developed a new energy storage system based on dual-ion battery technology. Its long service life is promising for stationary applications.  more...
