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...

Anyone generating electricity or operating high-temperature industrial processes produces waste heat. This waste heat is often not utilised, since its economic use does not seem viable. Small plants using the Organic Rankine Cycle (ORC) promise help here: they make the waste heat usable in the form of electricity, improve the cost-effectiveness and reduce CO2 emissions. Researchers from Saarland have developed an engine that uses low-temperature heat to generate electricity very efficiently for a large range of uses.  more...

While the amount of process heat produced from solar sources is still low, the potential is high. Heating chemical baths, generating solar cooling and using hot air in a drying oven: these are classic examples of process applications. Now a metal finishing plant near Wuppertal has achieved first time worldwide by connecting its own steam network to parabolic trough collectors in which steam is generated directly in the absorber pipe. This simple technology eliminates the need for thermal oil as a heat transfer medium and saves on fossil generated energy.  more...

Copper cables only conduct electricity under resistance, meaning the cable heats up and energy is lost. In contrast, superconductors conduct electricity without loss. Their use in cable and generator projects thus increases the efficiency of the electricity supply infrastructure. With this in mind, the German Federal Ministry of Economics and Technology is promoting the cost-effective production of superconductive band conductors at the manufacturer Zenergy Power with funding of 3.5 million euros.  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...

Cleaning, drying, dyeing, pasteurising, bleaching and melting - at first glance, the potential for utilising solar process heat in industry seems enormous. The aforementioned selection of cross-sector processes is at least partly suitable for provision with solar thermal energy. Despite this, the number of applications that actually use solar process heat lags far behind its theoretical potential. This is partly due to the fact that this is a new application area for solar thermal energy.  more...

Solar energy is already used for air conditioning buildings, and now researchers want to use it to refrigerate fruit and other easily perishable food. Scientists from the Fraunhofer-Institute for Solar Energy Systems ISE in Freiburg are demonstrating its feasibility in the Mediterranean region using the example of a winery in Tunisia and a dairy in Morocco.  more...

Several industrial products have to go through fire during production. In the metalworking industry, in the production of glass, ceramics and building materials as well as in parts of the food industry, heating processes are key production steps. About 65% of the industry's final energy requirement is expended on it. In Germany, industry furnaces are chiefly produced by small and medium-sized companies and close to every second furnace is exported.  more...

Heat recovery from exhaust gases and flameless combustion - this is the magic formula in many high-temperature processes in order to combine optimal fuel usage with low nitrogen oxide emissions. With a new recuperator burner, this technology now also offers advantages in the lower range of outputs under 100 kW. The exhaust gas losses have been almost halved compared to conventional recuperator burners. A number of burners of this type have been undergoing tests since early in 2009 in heat-treatment equipment for screws.  more...

The German Federal Ministry of Economics and Technology has published a strategy paper entitled "Eckpunkte und Leitlinien zur Weiterentwicklung der Energieforschungspolitik der Bundesregierung (Cornerstones and guidelines for the continued development of the German federal government's energy research policy)". The detailed analyses and suggestions were developed as a result of the cooperation between a number of institutes in the Helmholtz Association of German Research Centres as part of a broadly based consultation process.  more...
