    Thermal storage systems brought into shape

    Thermal storage systems that utilise zeolite are still very rare. In a research project, scientists have investigated aluminosilicates for their practical use in thermal storage systems. They have succeeded in significantly improving the energy density, cycle resistance and thermal performance. The research has led to the development of a thermochemical storage system for a CHP power plant.  more...

    Stable grid with 100 per cent green electricity

    In a power grid, the energy provided must always be equal to the power demanded. Only then can frequency and voltage remain stable. Ensuring this is the task of grid operators. But when volatile — meaning not arbitrarily adjustable — energy sources are the main sources of electrical energy, grid operators face a challenge.  more...
     

    Virtually linking mini-CHP systems

    Linked decentralised combined heat and power plants (CHP) and electric loads will be able to participate in the electricity market in the future by forming a regional and virtual power plant. This will compensate for power fluctuations and create more flexibility while being economic and efficient. The research association ‘Thermal and electric CHP linking’, coordinated by TU Dresden, presented their results.  more...
     

    Increased range, reduced costs

    One million electric vehicles by 2020 – that is the declared goal of the German Federal Government. However, existing battery systems are not suitable enough for everyday use. In the joint DriveBattery2015 project, developers are therefore designing a new control and interconnection concept. Their aims: to increase the range, reduce costs and make electric cars more reliable. The first phase of the DriveBattery project has now come to an end – time for an interim balance.  more...
     

    Interim findings of the Energy Storage Research Initiative

    Which contribution can energy storage systems make to the energy transition? How can they be employed economically? And what are the future research priorities? These were the questions answered during the 2nd status seminar on energy storage systems in Berlin last week. Half-time for the Energy Storage Research Initiative, and time to look at the score.  more...
     

    Standardised feed in of solar heat

    Solar thermal systems are very suitable for retrofitting into existing buildings. However, a lack of standardisation exists when coupling the system to a district heating network. Viessmann and the Technical University of Dresden are therefore developing suggestions for future standardisation. This should help to reduce the planning effort required and save costs through unification of the various circuit variants.  more...
     

    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...
