Abstract

The concept of carbon dioxide sequestration in deep ocean as an option to control global warming due to the emission of Co? from fossil fuel fired thermal power stations is worthy of research & investigation. Lot of research work has already been taken up in various countries in different associated areas such as finding suitable chemicals for recovery of carbon dioxide from gases, alternative methods of CO₂recovery, pre-combustion CO₂ recovery from gaseous fuel obtained from gasification of solid fuel, reactions of sea water with carbon dioxide at the pressure & temperature of deep sea, etc. There are many areas in which research has to be accelerated or taken up such as effects of carbon dioxide on marine ecology, development of mechanically strong and economically feasible method of delivery of liquid carbon dioxide in deep sea offshore, economical methods of transportation of captured CO? to designated locations, investigations covering deep sea dissolution of carbon dioxide, dispersion and Clathrate formation etc.
