    Stepping-up battery research

    An expert commission of the Technology Network of the International Energy Agency held a conference in Berlin on the topic of energy storage devices. Representatives of various member states voiced recommendations for future research into storage devices in a workshop. Battery technology was focussed on.  more...

    Local heating links newbuild with existing district

    By means of a district energy concept, researchers in Ludwigsburg are combining the advantages of ambitious building concepts and refurbishment measures with energy efficient heat supply. The heat required for the Sonnenberg development area is generated in winter using a brine/water heat pump in combination with a combined heat and power plant. The local heating network and its extension into the adjacent existing district of Grünbühl provide the post-war housing estate, which is in need of refurbishment, with not just greater living comfort but also energy efficiency benefits and cost savings.  more...
     

    Energy research on course to delivering the energy transition

    The German federal government recently published the National Action Plan on Energy Efficiency. The concept is specifically aimed at winning over all actors in society in achieving greater energy efficiency. A few days later, the German Federal Ministry for Economic Affairs and Energy announced its research funding for the German federal government’s 6th Energy Research Programme. In the BINE interview, Dr Rodoula Tryfonidou from the responsible department in the German Federal Ministry for Economic Affairs and Energy talks about the contribution made by energy research in bringing about the Energiewende – Germany’s energy transition.  more...

    Batteries in the low-voltage grid for more PV energy

    In areas where already a large number of photovoltaic systems are installed, impermissibly high voltages can occur in the power grid on sunny days. It therefore needs to be clarified how the energy generated can be optimally used both technically and economically. One idea is that new charging strategies for batteries can effectively relieve the grid by optimally integrating the energy storage systems.  more...
     

    Gas and heating networks act as energy storage systems

    Heating and gas networks can balance out fluctuations in the electricity grid. But how flexibly can surplus electricity be indirectly stored? In the Multi-Grid Storage project, scientists have investigated how it can be best of all stored in the form of heat or gas and then made available again as electrical energy as soon as it is required.  more...
     

    Identifying risks and minimising them through regulations

    How safe and reliable are photovoltaic installations with lithium-ion storage systems? In order to find out, scientists are investigating different plant systems. The intention is to identify possible weak points – such as during transport and installation – so that they can be taken into account in future standardisation work.  more...

    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...
