Processing metal with solar energy

03.11.2011
Solar-generated saturated steam fed into steam network at 140 °C

In Germany, industrial process heat comprises around 10% of the energy requirements. Part of it can be generated with solar thermal systems. Using twelve collectors that track the sun’s position, a metal processing company in Ennepetal, Germany, has for the first time generated saturated steam and integrated it into an existing steam network.

The pilot system is presented in the new BINE-Projektinfo brochure “The sunny side of saturated steam” (11/2011). In this research project, the process’s operational basis for utilising solar process heat was tested and optimised, whereby a particular focus was on the future use of such systems in more southern parts of the globe.

Saturated steam is steam produced at the saturation temperature and is used in many industrial production processes up to 200 °C. In the pilot system, steam is generated directly in the absorbers within the parabolic trough collectors, thus eliminating the need for a special heat exchanger. This improves the efficiency. A company in the aluminium-finishing sector has integrated the solar steam generator into its existing steam network. Here, the steam is used to quickly heat various chemical baths to temperatures between 60 and 110 °C. As expected, the solar yields from this pilot system were relatively low, which is partly due to the limited collector surface area. The project itself, however, was deemed to be successful because it enabled a highly promising process for generating and directly feeding solar steam to be realised and tested in long-term operation. The process could also be used in other sectors for drying and heating processes and for solar refrigeration.

In order to achieve temperatures above 100 °C with solar heat, concentrating collectors are deployed. The pilot system uses parabolic trough collectors – a technology in which German companies are among the best in the world. The BINE Projektinfo brochure “The sunny side of saturated steam” (11/2011), which can be obtained free of charge from the BINE Information Service at FIZ Karlsruhe, is available online at www.bine.info.

Im Focus: Making Waves

Computer scientists use wave packet theory to develop realistic, detailed water wave simulations in real time. Their results will be presented at this year’s SIGGRAPH conference.

Think about the last time you were at a lake, river, or the ocean. Remember the ripples of the water, the waves crashing against the rocks, the wake following...

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
