A special purpose project company founded by Fels-Werke GmbH from Goslar in Germany has won the Innovation Award for Climate and Environment for a process that uses lime to produce pure synthesis gas from pollutant-rich waste and biomass. The German Federal Ministry of Economics and Technology provided 4.5 million euros of support for this project. Since 2009, this award has been honouring concepts from Germany that contribute to climate and environmental protection and, at the same time, strengthen the country as a business location.  more...

Special micro-organisms can make direct use of the carbon dioxide (CO₂) contained in flue gases from lignite-fired power plants as ?food?, and grow even at a temperature of 60 degrees Celsius. This is the interim result of the research cooperation between an electricity producer and a biotechnology company at the Niederaussem power plant near Cologne.  more...

Even in a remote village far from the public electricity grid there is modern everyday life with radios, washing machines and electrical appliances. In energy terms this is a ?standalone? system. The electricity is supplied by a hybrid system that combines various renewable energy sources and an additional diesel generator, and is buffered with a battery system. An information and control network with a new operating system keeps the stand-alone grid (mini-grid) stable.  more...

Its sounds ideal: a domestic energy plant that generates heat and electricity works almost without emissions and also exclusively utilises the sun and bioalcohol as renewable energy. Researchers from the Fraunhofer Institute for Solar Energy systems ISE are working on such a plant. The heart of the system comprises a fuel cell combined with a newly developed reformer that generates the hydrogen required for the fuel cell from bioethanol.  more...

The political conditions for a change in energy policy (from fossil fuels and nuclear energy to renewable energy sources) have never been better. However, a successful change in energy supply can only take place with the support of private households who change to green electricity and homeowners who invest in renewable energy technology. How can potential users (and especially women) be persuaded to change? The interdisciplinary research project "Renewable energy sources and green electricity - communication according to specific target groups" intended to find the answer to this question.  more...

In its 2010 Annual Report, the German Federal Ministry of the Environment has presented its focal areas for funding research in the field of renewable energies. Topics include wind energy, photovoltaics, solar thermal energy, solar thermal power plants, geothermal energy, the optimisation of energy supply systems, ocean power, interrelated issues and international collaboration.  more...

There are already more than 100 regions and many rural communities that are promoting sustainable development based on renewable energies. After developing individual concepts and strategies, the lengthy and often very complex implementation begins. A research project organised by the German Federal Ministry for the Environment has been supporting these regions in conceptual and technical terms since 2007. This project is being conducted by the deENet competence network and the University of Kassel, and is being advised by the German Federal Environment Agency. In a second project phase, it is planned to create a national network by 2013.  more...

The eagerly anticipated draft version of the "Lead Study 2010" can now be downloaded. The study, entitled "Long-term scenarios and strategies for developing renewable energies in Germany taking into account developments in Europe and worldwide", is available on the website of the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety. For the first time the study carries out a complete dynamic simulation of the electricity supply and describes the technical and economic impacts of developing renewable energies.  more...

In 2009, renewable energies met 11.6% of the gross final energy consumption of the European Union, whereby they generated 18.2% of the electrical energy supplies. Their economic importance is also growing: more than 900,000 workers in the various sectors generate a turnover of 120 billion euros. These are the results of the tenth report published by the EurObserv'ER consortium on "The State of Renewable Energies in Europe". The annually published report describes not just the development of the various technologies, broken down according to the respective EU countries, but also explains their socio-economic importance. The documentation, which is published in English and French, can now be downloaded free of charge.  more...

The Internet offers rapid and convenient access to information ? including for energy research. However, when it comes to obtaining reliable, complete and quotable information for research purposes, there is no real alternative to using specialist databases. This is the conclusion of scientists from the ETDE (Energy Technology Data Exchange). In a study they compared the search results provided by their ETDEWEB database with those from Google and Google Scholar, whereby they used search terms from different areas concerned with energy transformation and utilisation. The main thematic focus was on renewable energies, but energy efficient technologies such as recycling waste heat or utilising daylight in office buildings were also looked at.  more...
