Phase diagrams of carbon dioxide, nitrogen and their mixtures with different amounts of nitrogen (e.g. 5 mol%, 10 mol% N2) were calculated with high accuracy with the NIST Reference Fluid Thermodynamic and Transport Properties database program REFPROP® for up to 200 bar, as well as density-pressure diagrams. Beside the use of carbon dioxide as a solvent for supercritical fluid extraction, incre...

Carbon capture and storage (CCS) is seen as one of the key technologies for cutting CO2 emissions from coal power plants. It is proposed that carbon capture and storage could reduce CO2 emissions to the atmosphere from a modern power plant by approximately 80-90%. Building and operating infrastructure for capturing, transporting, and storing CO2, however, is forecast to be expensive. To gain a ...

Carbon dioxide capture and storage (CCS) is one option for mitigatining atmospheric emissions of carbon dioxide and thereby contributes in actions for stabilization of atmospheric greenhouse gas concentrations. Carbon dioxide storage in geological formations has been in practice since early 1970s. Information and experience gained from the injection and/or storage of CO2 from a large number of ...

This paper has been presented at an expert meeting on CO2 capture technology learning at the IEA headquarters, January 24th 2003. The electricity sector is a key source of CO2 emissions and a strong increase of emissions is forecast in a business-as-usual scenario. A range of strategies have been proposed to reduce these emissions. This paper focuses on one of the promising strategies, CO2 capt...

Recently, the capture and storage of CO2 have attracted research interest as a strategy to reduce the global emissions of greenhouse gases. It is crucial to find suitable materials to achieve an efficient CO2 capture. Here we report our study of CO2 adsorption on boron-doped C60 fullerene in the neutral state and in the 1e (-)-charged state. We use first principle density functional calculation...

Understanding the impacts of leaks from geologic carbon sequestration, also known as carbon capture and storage, is key to developing effective strategies for carbon dioxide (CO2) emissions management and mitigation of potential negative effects. Here, we provide the first report on the potential effects of leaks from carbon capture and storage sites on microbial functional groups in surface an...
