    Storing surplus electricity in the natural gas network

    Surplus electricity can be used in Power-to-Gas systems to generate hydrogen by means of electrolysis. Downstream methanation provides a possibility for storing the remaining gas that cannot be directly used or fed into the natural gas network. The initial, highly promising results for a newly developed biological process have now been presented. The test facility has a low energy requirement and the process is continuous. The system is suitable for decentralised and small systems.  more...

    Research on large-scale battery storage system

    The modular, large-scale M5BAT battery storage system recently began operating in Aachen, Germany. With a 5 MW output and a storage capacity of 5 megawatt-hours, it is the largest battery storage system currently being researched. Together with industrial partners, scientists at RWTH Aachen are testing the interaction of five different battery types and are developing business models for decentralised storage systems in actual grid operation.  more...

    A town acts as a storage system

    How can urban regions contribute more to the energy transition? To find this out, scientists are investigating virtual energy storage systems in Herten in North Rhine-Westphalia and in Wunsiedel in Bavaria. The field trial started on 30 June 2016.  more...

    Energy storage systems in 2030

    What role will functional storage systems play in the energy supply system of the future? Which system infrastructure can economically secure a reliable energy supply in 2030? And what measures must the government take so that this system infrastructure can prevail on the market? Scientists at the Research Center for Energy Economics (FfE) are trying to get to the bottom of these questions with an ongoing study. The results are now available.  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...

    A second life for car batteries

    The demands that drivers place on electric vehicles are high indeed: both range and performance have to be sufficient. In addition, batteries are subject to a steady decline of capacity. As performance and capacity deteriorate, a new battery is needed. Retired units are still suitable for other purposes, for example, for raising the self-consumption of solar power systems or supporting the grid.  more...

    Lime storage systems: Cheap, efficient and sustainable

    At the German Aerospace Centre (DLR), researchers are using lime as a storage medium in a specially developed heat storage system. This enables heat to be stored in the form of a reversible reaction. Such storage systems can help large amounts of energy to be used more efficiently in industrial processes and households. The new plant has now been put into operation.  more...

    World’s largest electrolysis plant inaugurated

    The world's largest electrolysis plant of its kind has been created in Energiepark Mainz. It has an electrical connected load of six megawatts and can produce up to 1,000 cubic metres of hydrogen per hour from renewably generated electricity. The hydrogen produced can be stored on site, transported in tanks or fed into the natural gas network where it can be used at a later point for generating electricity or heat. The plant has now been officially inaugurated.  more...

    Preparing the electricity grid for electric vehicles and heat pumps

    The electricity grids in Germany have to be expanded to cope with decentralised generators and increasingly more large-scale loads. For grid operators it is therefore important to gain an overview of the necessary measures and their effectiveness even before installing new operating resources. Special simulation and planning tools are suitable for this. As part of the Novel E-Mobility Grid (NEMO) research project, scientists at the Fraunhofer Institute for Solar Energy Systems ISE have developed a software programme that can help to analyse and plan power grids.  more...

    Does the energy transition need energy storage systems?

    The fact that energy storage systems have a role to play in the energy transition is hardly controversial. But statements about the actual demand, competitive solutions and application scenarios sometimes contradict each other. The Fraunhofer institutes UMSICHT and IWES have examined studies on the topics of electricity storage systems and Power-to-Gas.  more...
