    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...
     

    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...
     

    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...

    Researching in the global network

    International research collaborations are becoming increasingly important. Germany is involved in a variety of ways in international energy research. An important pillar in this regard is its involvement in the International Energy Agency (IEA). Germany is a founding member of this organisation. An IEA field of activity particularly relevant to energy research is its energy technology network.  more...
     

    Power plants become partners of renewables

    The “Partner-Dampfkraftwerk” research project, which has now begun, aims to significantly improve the demand-driven integration of electricity from fluctuating energy sources. For this purpose, their goal is that existing power plants will reliably balance out the fluctuating power from wind turbines or photovoltaic systems, in order to ensure grid stability. The optimisation measures could already be installed in the short term in existing power plants. With this aim in mind, four power plant operators are collaborating with three research institutes and two components manufacturers, under the project management of VGB PowerTech.  more...
     

    Direct steam generation for more efficient solar power plants

    At the Almería Solar Centre in Spain, a test plant for direct steam generation has commenced operation. Instead of thermal oil, water is heated in the receiver tubes in the parabolic troughs. This allows higher temperatures and saves on plant components. This year the scientists are testing the control system in the 3-megawatt plant.  more...
     

    Phase change stores heat

    When it comes to transporting heat from boilers to heating surfaces or supplying cooling energy to cooling ceilings, water has proved to be an excellent heat transfer medium. However, in some application areas it is now facing competition: various research groups are working on heat transfer fluids that have at least double the energy density. Phase change materials such as paraffin, which are finely distributed in water, store heat when they melt and release it again when they solidify.  more...
     

    Rail travel with water and wind

    It is a core problem of the energy revolution: the fluctuating yields from renewable energy sources have to be integrated into the electricity supply without endangering its safety and economic feasibility. Here the Deutsche Bahn railway company provides a prime example: by 2020, the company intends to draw more than one third of the 12 billion kilowatthours it consumes each year from green electricity. Researchers have calculated that doubling the green electricity used today will increase the electricity costs by around five per cent. The German railway power grid is distinguished, however, by many unique features.  more...
     

    Leisure pool creates a stir

    In November 2011, the "Bambados" Swimming Pool - a leisure pool built to the passive house standard - opened in Bamberg, Upper Franconia. The monitoring is starting at the beginning of April. The measurements will show whether the concept proves itself in practice and whether the planned energy savings can also be achieved in reality. In the BINE interview, Esther Gollwitzer from the Passive House Institute (PHI) discusses the concept behind the new leisure pool and draws an initial balance.  more...
     

    Jump starting electrical storage

    Representatives from science, research and industry converged on the town of Münster to attend the 2012 Battery Day and the subsequent Advanced Battery Power symposium. This year, the conference focused on the potential offered by electrochemical energy storage. The German Federal Ministry of Economics and Technology (BMWi) confirmed at the conference that energy storage played a crucial role in grid stability.  more...
