Carbon capture and storage (CCS) is a concept in which carbon dioxide that is produced from industries is captured and pumped deep beneath the seafloor. Klaus Wallman, a marine geologist, discusses the first project of CCS on an industrial scale at Sleipner in the North Sea. Possible risks at storage sites include carbon dioxide leakage, abandoned wells, and atypical structures forming on the seafloor. The consequences of leakage include ocean acidification and a loss in biodiversity at all levels. Carbon dioxide leakage at the seafloor does not reach the atmosphere, however. The impact on organisms for leakage is local and at a small scale. The conclusions are that it is definitely better to equip a coal power plant with CCS technology than to emit into the atmosphere, but the answer may vary in different countries with different local conditions.
