Research Keyword: Carbon fixation, microbe, CCS, carbon capture and sequestration
The purpose of this project is to develop a technology to cause microbially-aided carbon precipitation by injecting CO2 into a rock in deep underground with anaerobic bacteria, elements, and nutrients. The proposed technology is deeply related to the prevention of global warming with carbon capture and sequestration generally abbreviated as CCS. CCS is one of technologies being developed around the world to reduce the amount of CO2 released into the atmosphere by injecting carbon dioxide into deep underground with a depth of more than 2000 m. The technology is deemed necessary to achieve the Paris Agreement, but there are several concerns to be addressed, one of which is CO2 leak-off to the ground surface through pre-existing rock mass fractures and geological structures such as faults and fractured zones. The microbially-aided carbon precipitation can contribute to mitigating the risk for CO2 leak-off by transforming injected CO2 into a precipitated carbonate with the help of microbes.
