CO2 quality in the ship-based CO2 capture context. Deliverable D2.4.1.
report
The EverLoNG project covers multiple aspects of the marinization of CO2 capture – from techno economic to environmental and regulatory aspects. In this deliverable, the quality of captured CO2 is discussed, in view of expected impurities and the most recent CO2 specifications from transport and storage CCS projects. Onboard Carbon Capture (OCC) was demonstrated in EverLoNG onboard 2 vessels. In both campaigns, the impurities content in the exhaust gases and from the OCC pilot were monitored. The most relevant observation made in the context of CO2 quality is the relatively high NOx content in the exhaust gas of marine engines. At the Technology Centre Mongstad (TCM), a large CO2 capture pilot plant in Norway, the NOx content in the raw CO2 is measured at 0.5 ppmv, which is close to the Northern Lights and Aramis specifications (1.5 ppmv1 ). However, the reported NO2 content in the flue gases of TCM is below 2.5 ppmv, whereas in the EverLoNG campaigns values in the 50-250 ppmv range were measured (data publicly shared in EverLoNG webinars2 ). This indicates that the NOx content in OCC-produced CO2 will potentially be higher than specifications.
