CO2 emissions from various sources are pointed out as one of the causes of global warming, fossil fuels may play a strong role on it; renewable energy sources can in the future cope with the problem, in the meantime fossil fuels are fundamental to assure a reliable energy supply. However mitigating plans have been already taken in account, as increasing overall efficiency, bio fuels, developing clean measure to reduce CO2 footprints on residential, domestic and transportation consumptions. Among the emerging technologies, CCTS (Carbon Capture Transportation & Storage) appears to be the most promising to be applied to concentrate emitters as Power Plants or Industrial Mills. This paper specifically deals with transportation challenge when carbon dioxide is gathered in liquid phase (dense or supercritical) via pipelines and the efforts to put in place proper testing facilities to better understand the behavior of the carbon steel of the pipes when exposed to the mixture of CO2 plus impurities, with the aim to create specifically addenda to the existing Oil&Gas pipeline standards.
Carbon dioxide (CO2) acts as one of the major contributor in "Global Warming" among the green house gases GHG; it has been evaluated that up to seventy percent of CO2 emissions come from fossil fuel power plants. There are three stages, Carbon Dioxide Capture at fossil fired plants and other fuel conversions plans, Carbon Dioxide Transmission from the place where it is captured to the place where it is to be stored underground, i.e. Storage. In the last ten years or more Capture and Storage attracted large funding and several R&D initiatives were launched on these two topics, mainly with the aim to reduce the cost at the capture stage (in term of energy penalties) and make the storage permanently secure.
