    Hydrogen – storing energy in metals

    Metal hydrides store hydrogen and heat. Their use in thermochemical storage systems is hampered, however, by the material's poor heat conductivity. To increase the charging and discharging performance, researchers are pelletising the material together with graphite, which has a high thermal conductivity. With different metal hydrides they can cover the temperature range from room temperature up to 400 degrees Celsius.  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...

    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...

    Electric cars stabilise the grid

    How can users of electric cars recharge their batteries flexibly, help relieve the grids and save money in doing so? Researchers examined at what point electric cars become a benefit for grid operators and vehicle owners. Their field test demonstrates the conditions this depends on.  more...

    More energy for electric cars

    In the alpha Laion research project, the alliance partners are aiming to develop improved batteries for electric cars. These are intended to provide a high energy density and cycle stability, which will increase the range of the vehicles and ensure a long service life. The researchers developed and tested new materials and compositions for the anode, cathode and electrolyte. The results of the project have now been presented.  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...
     

    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...
     

    Research funding for the energy turnaround increasing

    Energy research contributes towards the development of the processes and technologies necessary for achieving the goals of the energy turnaround. The German government has been continuously increasing funding for energy research since 2006. In 2013 alone, it spent 100 million euros more on this than in the prior year. This reinforced above all the research areas of energy efficiency and renewable energy sources. It provided just under 300 million euros for each of these subjects.  more...

    The use of electric vehicles in urban delivery traffic

    Around one third of the traffic in cities consists of trade contractors and suppliers. Until now, this so-called commercial traffic has mostly relied on diesel power. Electric vehicles, however, could provide an ecologically, technically and economically viable alternative, since the typical operations and routes used by care services, parcel couriers and contractors match the short ranges provided by electric vehicles. A research group led by the Technische Universität Berlin is now investigating how electric vehicles could be sensibly used in the urban commercial traffic.  more...

    Lithium-ion batteries in mass production

    At the Karlsruhe Institute of Technology (KIT), the small-scale production of lithium-ion cells has begun. The goal in the research factory is to reduce production costs by developing process engineering for the mass market. Researchers aim to use this to help the lithium-ion batteries make a breakthrough as stationary and mobile storage facilities.  more...
