    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...

    Combining compost and biogas

    A new method improves the energy balance and processing capacity of composting plants. With the usual composting process, considerable energy is consumed to provide the required mechanical ventilation. In the new method, the liquid organic components of the organic waste are separated in advance and are used for producing biogas. This enables energy to be generated in the plants. For the project, a new biofilm digester has been designed which provides cost advantages relative to other digestion processes.  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...

    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...

    Database shows output from renewables

    The sources of renewable energy –sun, wind, water and biomass – account for a large share of the electricity production in Germany. At the beginning of July 2014, solar energy covered the entire peak load. This is shown in the new online “Energy Charts” database at the Fraunhofer Institute for Solar Energy Systems ISE.  more...

    Heating with vegetable oil

    The Oel-Waerme-Institut has joined forces with partners in industry and science to develop a burner system that runs on heating oil, vegetable oil or a mixture of both. In a range from 5 to 25 kilowatts, continuous modulation adjusts the output to current requirements. The project, which is subsidised by the German Federal Ministry of Economics, focuses on optimised fuel mixture control and atomisation. The resulting low-emission burner systems can be used in central heating systems in buildings with low heating capacities.  more...

    Using the internet to create a large-scale power plant

    Many small, decentralised power generators could replace conventional large-scale power plants. But how can wind, sun and bioenergy be integrated into the future power supply system? With the “Kombikraftwerk2”, researchers aim to show how power generation from 100 per cent renewable energies can be achieved and stabilised.  more...

    Smart regulation of rural electricity grids

    In the "Smart Country" model project, researchers in Bitburg-Prüm were testing out the distribution network of the future. It is designed to respond flexibly to the increasingly decentralised generation of renewable electricity in the grid. For this purpose various operating resources were further developed: an optimised biogas plant, which controls the electricity supplied by the grid, virtually stores surplus electricity with an efficiency of 98 %. In addition, voltage regulators double the usable output capacity in the grid. The Eifel project successfully passed the field test after around one year.  more...

    Research becoming increasingly important

    At the Annual Conference of the Renewable Energy Research Association (FVEE) on 16 and 17 October 2012, scientists and industrial representatives presented innovations along with new strategies for their market introduction. In his opening speech, Federal Environment Minister Peter Altmaier emphasised that greater importance should be given to research and development in regard to the era of energy revolution.  more...
