With the world gearing up to cut down carbon emissions to combat the greenhouse effect, a novel method has been introduced to collect and store co2 after pressurizing and liquifying it. carbon sequestered will either be put to use in industries or will be buried deep underground. this concept is highly revered due to its pragmatism and simplicity and is broadly termed as "carbon capture, utilization and sequestration/ storage (ccus)". though it is clear how to capture, utilize and store liquified co2 (lco2), the modus operandi of transportation remains abstruse. though the technical feasibility of this method is still under debate, many shipping companies have set forth to construct liquified co2 (lco2) tankers. ongoing studies are focused on finding the best methods to transport co2 by retrofitting lng ships to better equip them for storing and transporting co2. this paper takes a systematic approach to review the development of lco2 tankers. it discusses the trail of development, major challenges and limitations, technological gaps, and future prospects. it also looks over the economic and ecological aspects of such an endeavor. the paper has also taken care not to be oblivious to other options at hand, including pipelines and railways. it briefly explains the above methods and further discusses their limitations.
