Abstract
The invention relates to a process and vehicle for the disposal of carbon dioxide. Gaseous carbon dioxide is solidified and allowed to free fall through open water where i at least partially embeds itself in sedimentary formations. Sedimentation ensures that the marine environment is an overall carbon sink through carbonate sequestration.
Claims11
A process for the disposal of gaseous carbon dioxide comprising the steps of:
- Solidifying carbon dioxide;
- and
- embedding the solid carbon dioxide in open water floor sediment, wherein the depth and temperature of the open water floor sediment are such that the solid carbon dioxide can transform to a clathrate.
