Carbon dioxide storage in hydrate reservoir

Tildelt: kr 4,0 mill.

The London Dumping treaty puts heavy constraints on options for CO<sub>2</sub> storage that will be accepted according to this treaty. Storage of CO<sub>2</sub> in natural gas hydrate reservoir is one of the safest options for storage of CO<sub>2</sub> . Compared to ocean sequestration and reservoir storage this option is economically balanced by the value of the produced gas. Japan has a goal to start exploitation of a hydrate reservoir offshore the coast of Japan (at depths of 3000-4000 m). This hydr ate reservoir alone is estimated to provide Japan with energy for the next 100 years. Conversion of natural gas hydrate reservoir to carbon dioxide hydrate reservoir is the strategy in focus according to current research programs in Japan on these issues. In an international perspective an increased fundamental understanding of hydrate conversion can contribute to Norwegian industrial participation in this exploitation project. The CO<sub>2</sub> from planned Norwegiangas power plants can be transported to Norwegian gas hydrate reservoir.
