Environmental Principles

Sato, Toru
Marine Environmental Engineering, Environmental Impact Assessment of CCS, Modelling of Gas Hydrate Formation/Dissociation, Development of Photobioreactor to Cultivate Microalgae


Professor Toru Sato has been engaged in environmental impact assessment of CO2 sub-seabed geological storage (CCS), development and application of multi-scale ocean model, development of dissociation and formation models of methane and CO2 hydrate, design and feasibility study on CO2 storage in the form of gas hydrate and has written number of articles on the topics in internationally influential journals. He has also devoted himself as the members of some governmental committees, such as Technical Committees on CO2 Ocean Sequestration of RITE, Sub-Seabed CCS of RITE, Environmental Impact Assessment for Sub-Seabed CCS of MOE, Antarctic Expedition Ship of MEXT, Ocean-Space Collaboration of JAXA, etc. From 2013 to 2014, he dedicated himself to the school as Chair of Environmental Studies, Graduate School of Frontier Sciences, University of Tokyo.
