Study flags port infrastructure as barrier to CCS for shipping

Onboard carbon capture and storage (OCCS) has recently gained traction as a potential interim solution to help international shipping meet its emissions reduction targets. While achieving emissions reductions through OCCS hinges on successfully integrating a shipboard-compatible system within space constraints, dealing with captured CO2 presents another set of challenges.

Carried out in collaboration with Lloyd’s Register and ARUP, the study found that while a limited number of ports possess the infrastructure to offload liquefied CO2 (LCO2), they are primarily designed to handle food-grade CO2. As food grade CO2 demands higher purity standards than carbon capture, there is limited scope for interoperability between facilities.

“While pilots have successfully demonstrated numerous capture technologies onboard ships, it is still uncertain how captured carbon on merchant ships can be safely offloaded, and what the rest of the value chain looks like,” said Professor Lynn Loo, CEO of GCMD.

“This study sheds light on these challenges, and highlights recommendations to holistically address these concerns for parties interested in advancing OCCS/LCO2 offloading concepts.”
