A new class of ship is emerging to support offshore sequestration of CO2 from industrial sources. Industry growth has led to the evolution of cargo management systems on liquified CO2 (LCO2) carriers to meet new challenges.
The CO2 captured by hard-to-abate industries, such as steel, cement, and chemical production, can contain a range of impurities not found in the CO2 transported by sea for the food and beverage industry.
Its specific impurity profile depends largely on the source, its temperature and pressure, and capture and dehydration technologies. This matters for transport to offshore sequestration sites: water, SOx and NOx can increase corrosion susceptibility; hydrogen can risk
