Subsurface rock formations play an important role in the energy system as a supply of geothermal energy, and as a disposal site for CO2 and radioactive waste. On the other hand, the rock structure is complex, and the utilization of subsurface resources should be designed in harmony with the natural fluid flow and stress conditions in the subsurface. In our research, we aim to design sustainable energy systems in harmony with the environment by understanding the natural &#8220;structure&#8221; and &#8220;flow&#8221;. In addition, we have been exploring how new science and technology can be utilized in society and what an environmentally harmonious society may look like. In this respect, our research considers the exchange of people\u2019s ideas and opinions on energy systems, energy production and energy use.<\/div>\r\n<\/div>\r\n<div class=\"contents\">\r\n<div class=\"wrapper\">\r\n<h4>Topological data analysis for rock structures and structure-controlled flow experiments<\/h4>\r\n<div>To capture the complex structure of rocks and other materials, we quantitatively extract important structural information related to flow using topological data analysis. In addition, by using 3D printers and microfabrication techniques, we create accurate structural models, which have controlled and known structures. The 3D models are designed to improve our understanding of fluid flow processes through a combination of lab experimentation and numerical simulation, enabling us to find new relationships between &#8220;structure&#8221; and &#8220;flow&#8221;. In addition, we are developing numerical simulation methods for describing development of new reservoirs using supercritical fluids and for understanding mechanisms controlling fracture formation under supercritical temperature conditions.<\/div>\r\n<div class=\"photo\">\r\n<div class=\"clearfix\">\r\n<ul class=\"multi\">\r\n<li><img decoding=\"async\" src=\"\/jpn\/wp-content\/themes\/ifs\/images\/research\/division\/07_img\/7_001.jpg\" \/>Quantification of structures by persistent homology analysis<\/li>\r\n<li><img decoding=\"async\" src=\"\/jpn\/wp-content\/themes\/ifs\/images\/research\/division\/07_img\/7_002.png\" \/>Design of fracture network<\/li>\r\n<li><img decoding=\"async\" src=\"\/jpn\/wp-content\/themes\/ifs\/images\/research\/division\/07_img\/7_003.jpg\" \/>Direct flow simulation<\/li>\r\n<li><img decoding=\"async\" src=\"\/jpn\/wp-content\/themes\/ifs\/images\/research\/division\/07_img\/7_004.png\" \/>Flow experiment using a 3D-printed fracture network<\/li>\r\n<\/ul>\r\n<\/div>\r\n<\/div>\r\n<div class=\"clearfix\">\r\n<ul class=\"sdgs\">\r\n<li><img decoding=\"async\" src=\"\/jpn\/wp-content\/themes\/ifs\/images\/research\/sdgs_icon_e\/sdgs-07.jpg\" \/><\/li>\r\n<\/ul>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<div class=\"contents\">\r\n<div class=\"wrapper\">\r\n<h4>Design of sustainable geo-energy systems<\/h4>\r\n<div>Geothermal power generation can be carried out more sustainably by creating a recirculation operation in which water used for power generation is returned to the subsurface. The effectiveness of different recirculation strategies depends on the subsurface structure and flow connectivity between the wells that return fluid to the subsurface and the wells that produce hot geothermal fluid for power generation. In this study, we are developing methods for estimating the subsurface structure and well connectivity using results of tracer tests for flow evaluation and for optimally designing a sustainable water recirculation operation. This includes proposing new tracer testing methods using nano- and microparticles. Our optimization and estimation workflows incorporate tracer and thermal transport modeling, quantitative evaluation of uncertainty, model error estimation, and machine learning.<\/div>\r\n<div class=\"photo\">\r\n<div class=\"clearfix\">\r\n<ul class=\"multi\">\r\n<li><img decoding=\"async\" src=\"\/jpn\/wp-content\/themes\/ifs\/images\/research\/division\/07_img\/7_005.jpg\" \/>Tracer test in geo-energy systems<\/li>\r\n<li><img decoding=\"async\" src=\"\/jpn\/wp-content\/themes\/ifs\/images\/research\/division\/07_img\/7_006.png\" \/>Uncertainty quantification<\/li>\r\n<li><img decoding=\"async\" src=\"\/jpn\/wp-content\/themes\/ifs\/images\/research\/division\/07_img\/7_007.jpg\" \/>Flow experiment with particle tracers in rock structures<\/li>\r\n<\/ul>\r\n<\/div>\r\n<\/div>\r\n<div class=\"clearfix\">\r\n<ul class=\"sdgs\">\r\n<li><img decoding=\"async\" src=\"\/jpn\/wp-content\/themes\/ifs\/images\/research\/sdgs_icon_e\/sdgs-07.jpg\" \/><\/li>\r\n<li><img decoding=\"async\" src=\"\/jpn\/wp-content\/themes\/ifs\/images\/research\/sdgs_icon_e\/sdgs-12.jpg\" \/><\/li>\r\n<\/ul>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<div class=\"contents\">\r\n<div class=\"wrapper\">\r\n<h4>Optimization of resource utilization through dialogue and data visualization<\/h4>\r\n<div>change, it is necessary to optimize utilization of local resources in local communities.
