    <title language="eng">Supercritical CO2-corrosion in pipe steels during carbon capture and storage CCS</title>
    <abstract language="eng">The CCS technique involves the compression of emission gasses in deep geological layers. To guarantee the safety of the site, C02-corrosion of the injection pipe steels has to be given special attention when engineering CCSsites. To get to know the corrosion behaviour samples of the heat treated Steel 1.72252CrMo4, used for casing, and the stainless injection-pipe Steel 1.4034 X46Cr 13 were kept at T=60 °C and ambient pressure as well as p=100 bar for 700 h - 8000 h in a C02-saturated synthetic aquifer environment similar to possible geological on-shore CCS-sites in the northern German Basin. The isothermal corrosion behaviour obtained by mass gain of the steels in the gas phase, the liquid phase and the intermediate phase gives surface corrosion rates around 0.1 to 0.8 mm/year at ambient pressure and much lower about 0.02 to 0.2 mm/year at 100 bar where the C02 is in its supercritical state. Severe pit corrosion with pit heights around 4.5 mm are only located on the 42CrMo4 Steel. Main phase of the continuous complicated multi-layered carbonate/oxide structure is siderite FeCO} in both types of Steel.</abstract>
