Abstract
The purpose of this study is to evaluate feasibility of a large-scale deep oceanwater (DOW) pumping-up/distribution system. In this paper, total CO2emission for two types of the DOW pumping-up/distribution systems, land-based andfloating-type, are assessed in their life cycle. The results of the assessmentsshow thatthe CO2emission from DOW storage system is largest at initialstage. At operational stage, the CO2emission from shuttle tanker fuelis quite large, and dominant in the total CO2emissions.
