To reduce the emissions of the ships on board capturing the co2 and depositing it in sediments of the seabed



The studies and the projects are multiplied that have the objective to reduce the polluting emissions of the ships, in order to allow with the marine transport to cut at least to 50% own gas emissions to greenhouse effect within 2050 regarding established level 2008 as within the International Maritime Organization(on 13 April 2018).

A new project, called decarbonICE, is based on board on the capture of the ships of the co2 produced from the engines and next storage of carbon in adapted sites, with the objective to return the conventional fuel use lacking in carbon. The project is got ahead by the Danish Maritime Development Center in collaboration with a group formed from shipowning societies, between which the Japanese Nippon Yusen Kaisha (NYK), the Sovcomflot Russian, the Norwegian Knutsen OAS and the Ardmore Shipping, that it has center in the Bermudas, from naval constructors, between which the South Korean Daewoo Shipbuilding & Marine Engineering Co. (DSME), and from the Brazilian mining society Is worth.

The project previews the capture of the emissions of carbon dioxide and other gases to present greenhouse effect in the smoke of drainage of the ship through a cryogenic process with their transformation in dry ice. Therefore, with tested technologies employed from the offshore industry, the dry ice comes successively deposited in sediments of the seabed where the co2 will be stoccata in sure and permanent way as co2 liquid and co2 hydrate.

The project decarbonICE, that it is started on October 1°, 2019 and it will be concluded in 2020, is developed with the scope is to adopt it on the ships of new construction is in order to already implement it on ships in service. The objective of the initiative is to draft a feasibility study and to start the procedure of approval of the technology near the IMO.

"Also supporting the final objective of availability of fuel to neutral carbon zero or carbon - the president of the project decarbonICE, Henrik O. Madsen has explained, former president and managing director of DNVGL - we consider that it is necessary a solution bridge without carbon, that it can use the existing resources in terms of ships, systems of propulsion and fuel. The project decarbonICE has the scope to offer this exactly, and with previewed energy penaly a lowland, very beneath of 10%".

Illustrating the reasons of the participation of the South Korean navalmeccanico group to the project, the production manager of DSME, Odin Kwon, it has found that "the marine industry seems to neglect that the capture of carbon on board with its next storage in appropriate sites can also be considered a solution without carbon emissions. To the DSME - it has announced - we are following various Korean groups of search that study the behavior of the co2 injected in sediments of the seabeds. The success of the project decarbonICE will depend also as reducing lessened the power demanded for the process of cryogenic cooling".
