Watanabe-Wang Lab
Machine-translated · View original
The lab works on underground resources and energy while looking ahead to their environmental risks.
AboutAbout the lab
Sustainable harmony between resources, energy, and the global environment.
The Watanabe-Wang Lab studies technologies for developing resources and energy, as well as technologies for assessing and reducing the environmental risks that arise in the process.
The core of its research is to clarify how materials move and circulate underground, in the geosphere.
Its work ranges from developing geothermal resources and removing carbon dioxide from the atmosphere to investigating soil and groundwater contamination.
The lab also works on data-driven science, which extracts essential laws from high-dimensional data.
Key terms
- Geosphere
- The region from the Earth's surface down into the ground that contains rock, soil, and groundwater
- Reservoir
- An underground layer of rock that holds steam, water, or gas. In geothermal power generation, it is where hot water or steam is extracted
- Carbonate mineralization
- Reacting CO2 with calcium and other elements to fix it as a solid carbonate mineral

ResearchResearch themes
Securing a stable supply of resources and energy requires not only exploration and development technologies but also ways of thinking that avoid or reduce environmental impact. The lab aims to understand the geosphere system that makes up the Earth, correctly estimate the movement and circulation of materials that accompany development, and scientifically predict and assess environmental risks.
*Illustrative imageSecuring resource and energy security
Based on an understanding of the geosphere system, the lab treats soil and groundwater contamination and the environmental and safety problems of resource and energy development as interdisciplinary research. It expresses complex flows and reactions in equations and develops numerical models of multiphase, multicomponent reservoirs.
*Illustrative imageAnalyzing geothermal reservoirs
The lab works on techniques for evaluating and analyzing the reservoirs used in geothermal resource development. Its targets are exploration and diagnostic techniques for the inside of boreholes, simulation techniques for calculating what happens inside a reservoir, and techniques for evaluating production behavior.
*Illustrative imageRemoving CO2 from the atmosphere
Reducing carbon dioxide emissions is a global challenge, and technologies that can reduce them quickly and substantially are in demand. The lab studies CO2 carbonate mineralization and fixation technologies, removal of atmospheric CO2 using silicate-based soil amendments, and methods for developing reservoirs using CO2.
*Illustrative imageEnvironmental risk assessment and management
In addition to contamination by hazardous chemicals, the lab takes up emerging environmental problems such as tsunami deposits. It identifies and quantifies environmental risks through monitoring, investigation, and analysis of pollutants, and studies technologies for risk reduction and risk management.
