    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 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...
     

    Foundry utilises waste heat from the melting furnace

    Together with industrial partners, researchers at ZAE Bayern are developing a cost-effective energy storage system for industrial waste heat. It shall enable discontinuously generated waste heat to be utilised for processes for which this has previously not been done for economic reasons. The implementation phase has now begun. The scientists want to put a demonstration plant into operation in the spring of 2018. It will be used to provide the waste heat from a foundry melting furnace from the metal industry as process or thermal heat.  more...
     

    Solar process heat

    Around three-quarters of the final energy consumption in the industrial sector in Germany is caused by process and space heating. Solar heat can be used in many different ways in the low-temperature operations in particular, as well as in the commercial, trade and services sectors. International studies confirm the global potential for this technology.  more...

    Networked factory stabilises the grid

    The factory of the future is flexible and networks the energy flows between machinery and buildings. The so-called Phi Factory is not only very energy-efficient, it also helps stabilise the electrical supply grid. The new model factory relies on a high share of renewable energy and helps smooth out electricity supply fluctuations.  more...
     

    Exhaust heat cools lorry cab

    Time for a break! The driver stops his lorry at the truck stop. To ensure that the cabin also remains cool even in summer, the engine also continues idling when the lorry is parked, often for hours. This produces noise and wastes fuel. However, researchers at the University of Stuttgart have now demonstrated that pleasant temperatures can still be reached even when the engine is switched off and there are no additional energy inputs. They have developed a special adsorption chiller. This utilises the exhaust heat produced while driving for air-conditioning the parked vehicle.  more...

    Pilot production of thermoelectric modules

    Thermoelectric generators convert waste heat directly into electricity. They utilise temperature differences and are paving the way for more energy-efficient production processes. However, the technology has previously led a niche existence because the module production is labour-intensive and therefore expensive. Researchers from Freiburg now want to improve this.  more...
     

    Ceramic cube reduces gas losses

    Scientists have developed a new ceramic heat exchanger for industrial furnaces. This can transmit considerably more exhaust heat to the combustion media than the metal recuperators currently used in high-temperature furnaces in the process industry. The new ceramic recuperator thereby decreases the exhaust gas losses to less than 25 per cent.  more...
     

    TU Darmstadt opens research factory

    Last week, the ETA model factory officially opened its doors. Here, scientists at the Technical University (TU) Darmstadt are researching under real conditions and at full scale how industry can use energy more efficiently by linking all building and production components. By considering the entire system – consisting of machines, energy storage systems, building technology and the building envelope – the intention is to reduce the primary energy requirement in production by 40 per cent.  more...
