摘要

CO_2 ocean disposal is one of several ways proposed to mitigate the greenhouse gas effect. In this paper, we estimate the cost of various CO_2 disposal options. The system consists of a conventional pulverized coal power plant, CO_2 separation using an amine scrubber, liquefaction and transportation. In this investigation, the power plant and the CO_2 separation plant are common. The liquefaction process and transportation systems are different. We evaluate the costs of pipeline, liquid CO_2 tanker for CO_2 lake, liquid CO_2 tanker dispersion, dry ice tanker and CO_2 dispersion by OTEC. The effect of distance between a power plant and the disposal site, plant size, and plant efficiency on the cost for each case is evaluated. Costs of ocean disposal options are estimated about 90 to 180 per tonne of CO_2 avoided. The least cost transportation option is dependent on the distance between power plant and site.
