A disposal technique for carbon dioxide, consisting of burying solid CO(2) penetrators into the deep seabed, has been proposed. The expected weight of these penetrators can be as large as 1000 tons with lengths between 20 m and 40 m and diameters of between 4 m and 5 m. In order to produce and dispose of such large penetrators, an engineering approach has to be developed to investigate the feasibility of the process from the sources (industrial and thermal electrical production sites) to the sink (deep marine geological formation). A 5 Mt/per year CO(2) disposal capacity, has been selected for the study. This corresponds to a 500 MW(e) coal fired power plant assumed to be in the vicinity of a coastal port. The selected penetrators are 540 tons weight, approximately 30 m high and 4 m in diameter. 2 concepts have been investigated. The first consists in producing penetrators at a land based factory and then shopping them to a disposal site in specially designed ships having the capacity of carrying 148 penetrators. The second assumes that liquid CO(2) can be collected from a port facility, transported by a liquid CO(2) container shop to a mobile marine penetrator production and launching platform. The costs of these solutions have not been evaluated in the present work.
