    Heat storage system with segmental design demonstrates its qualities

    In the “OBSERW” research project researchers have developed an innovative above-ground storage tank built using a cost-saving segmental construction method. This required a complete overhaul of conventional storage constructions and building technology. Numerous technical issues were put to rest, such as the temperature-resistant sealing of segments.  more...
     

    Multidisciplinary energy efficient production

    The closing event of the “ETA Factory” research project took place at TU Darmstadt on 11 April 2018. In the course of the project, a multidisciplinary research group was able to demonstrate the feasibility of energy savings of up to 40 percent in industrial production. The jointly planned research factory saw researchers optimise and network energy flows in production and within the building.  more...

    Storing power and heat in the district

    Sustainable energy provision is to be developed for the urban district of Rüsdorfer Kamp in Heide. The QUARREE100 research project is investigating how the district could be fully supplied with local or regional renewable energy sources. One goal is to integrate the regionally generated wind power into the regional energy system in an economically efficient and system-serving way.  more...
     

    Storing heat in mines

    What happens to mines that are no longer in use? Could they be used to store heat? Researchers are hoping to find this out and are conducting tests in the former Prosper-Haniel hard-coal mine in Bottrop to investigate whether it is suitable for underground heat storage. The GeoMTES research project is developing storage concepts for this purpose and a feasibility study will be carried out by September 2018. The modelling of the pit structure has now been completed.  more...

    From air base to residential neighbourhood

    A new residential district is being built on the site of a former air base in Oldenburg. In addition to new buildings, some of the former barracks buildings will be preserved and converted into residential buildings. A new infrastructure concept is planned that will couple the electricity, heating/cooling and electromobility sectors and integrate them into a cross-sectoral supply network. In addition, the project partners are developing a digital service platform to provide intelligent load and procurement management at the district level.  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...
     

    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...
     

    Night-time electricity from solar thermal power plants

    Together with the industrial partner Linde AG, researchers from the German Aerospace Center have further developed a latent heat storage system based on nitrate salts. In combination with a cascade of sensible heat storage units, the goal is to maintain the electricity production of solar thermal power plants at night and at times with low solar irradiation. To this end, the scientists have developed a storage system that can also be used for conventional steam power plants and industrial processes.  more...
     

    Salt stores heat

    Molten salt can store large amounts of heat at high temperatures. In Cologne-Porz, researchers at the German Aerospace Centre (DLR) are using a new test facility to find out where storage systems with only one tank could replace the common two-tank storage technologies. This would cut costs considerably. The system was presented to the public on 5 July 2017.  more...
     

    "You cannot put a football field in a cellar"

    Can new storage materials store unused solar thermal energy or industrial waste heat? What role could they play in cooling? To explore this, Dr Alexandra Lieb, head of the interdisciplinary junior research group NEOTHERM at the Otto von Guericke University Magdeburg, reports on her basic research on metal-organic frameworks and zeolites in this BINE interview.  more...
