Carbon Capture and Storage in the Sub-sea using Hydrate System
- Professor Toru Sato, Associate Professor Yoshihiro Konno
CO2 hydrate formed between the CO2 reservoir layer and the sea bottom is expected to yield self-sealing capability and realize sealing-layer-free Carbon Capture and Storage (CCS). This new concept of CCS using hydrate system is proposed based on collaboration research between industry and academia.
Laboratory experiments are conducted to observe hydrate formation in the artificial sediment layer and evaluate the sealing performance. In addition, numerical simulations are carried out in consideration of factors that affect the sealing performance by using data of the hydrate formation experiment.
