Power stations without greenhouse gas emissions

27.10.2006
The majority of scientists believe that carbon dioxide has an effect on our climate. The German federal government has therefore set itself the goal of significantly reducing CO2 emissions.

So-called CO2-free power stations will be an important topic for the German EU presidency starting in January 2007. The Fraunhofer Institute for Systems and Innovation Research ISI in Karlsruhe together with the Federal Institute for Geosciences and Natural Resources (BGR) has compiled and evaluated the current state of international research. The study conducted for the Federal Environmental Agency provides answers on which methods there are for capturing CO2 from power station emissions, how the gas can be stored below ground and what economic consequences the technology has.

The Fraunhofer ISI concludes that CO2 capture is an interesting bridging technology to significantly reduce the emissions of the greenhouse gas in the next 20 to 50 years until the full portfolio of regenerative energy sources has been developed including photovoltaic and solar thermal electricity. But it is not a miracle solution: power stations with CO2 capture consume one third more coal or gas and thus do not constitute progress towards a sustainable energy supply. According to studies of the BGR, storage possibilities for CO2 are mainly to be found in northern Germany. However, the suitability and capacity of individual underground structures are still unknown.

Whether CO2-free power stations are economic depends on the standard of comparison used. In spite of the complex technology involved, they are currently much cheaper than part of the renewable energy technology portfolio such as photovoltaic and geothermal electricity. If all the costs are taken into account including the costs for capture, transport and storage, avoiding one ton of CO2 costs about 40 Euro and is thus almost double what operators of conventional power stations have to pay for emission allowances under the emissions trading scheme. However, emission certificates will probably become more expensive so that the first large CO2-free power station which RWE plans to put into operation in 2014 could be competitive by then.

It is not certain how residents will react to underground CO2 storage in their vicinity. Legal issues of CO2 capture and storage also require clarification according to Fraunhofer ISI. So far, the laws concerning underground formations such as the Federal Mining Act or the Federal Water Act do not take CO2 storage into account.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
