Safe long term storage of CO2 is possible

08.11.2013
Conclusion of an international project for the geological storage of carbon dioxide

At the final conference of the EU project CO2CARE - CO2 Site Closure Assessment Research - at the GFZ German Research Centre for Geosciences from 04 to 06 November 2013 more than 60 experts from academia, industry and regulatory authorities from 13 countries discussed technologies and procedures for a safe and sustainable closure of geological CO2 storage sites.

Since 2004, GFZ investigates in an international research network the geological storage of the greenhouse gas. "Our work at the Ketzin site has shown that and how geological CO2 storage on a pilot scale can be done safely and reliably," summarized Axel Liebscher, project coordinator and head of the Center for Geological Storage (CGS) at the GFZ, the results of the meeting. "The knowledge gained in the project CO2CARE and newly developed procedures and technologies are a key step forward to implement the requirements of the EU Directive (DIRECTIVE 2009/31/EC) for geological storage of CO2 in national CCS laws and to ensure a safe and sustainable closure of geological CO2 storage sites."

The CO2CARE EU project, coordinated by the GFZ, combined experimental laboratory and field research as well as numerical simulations in an integrated approach and tested and developed technologies and methodologies. The result is that the three main requirements of the EU Directive for the transfer of responsibility to the appropriate regulatory body can be met: modelled behavior conforms with the observed behavior of the injected CO2, there is no detectable leakage, and the storage site is evolving towards a situation of long-term stability.

The key component of the CO2CARE project is the site-based research with an international portfolio of nine CO2 storage projects. In addition to Sleipner in Norway and K12-B in the Netherlands, the Ketzin pilot site operated by GFZ is one of three sites for which in the framework of CO2CARE the closure and the transfer of responsibility to the regulatory authority was theoretically developed. At the Ketzin pilot site the storage of CO2 was terminated in August 2013 after more than 5 years of successful operation. Axel Liebscher: "By now the post-injection phase has begun and the Ketzin pilot site will be the first site which will be closed within a scientific project. The results of the CO2CARE project will be implemented here directly."

Due to the continuing increase in world energy demand, especially in countries such as China, India and Brazil, and the use of fossil fuels the CCS technology will continue to play a central role in the global reduction of CO2 emissions. For Germany, it is especially also an option to avoid so-called process-related emissions from steel, cement and chemical industries. "Only if we can also demonstrate the safe and permanent closure of CO2 storage sites in addition to the safe operation, CCS is able to develop its potential," Axel Liebscher concluded.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
