Sustainable Carbon-Recycling System

Recycling methane through use of microbes

We are conducting joint research with the University of Tokyo on a sustainable carbon recycling system. This system for reuse of carbon dioxide (CO2) as an energy source starts with the application of CO2-to-methane biotechnologies in underground CO2 storage. The mechanism utilizes hydrogen-generating microbes to produce hydrogen from the petroleum left over in depleted oil fields. CO2 is injected into the targeted fields and reacts with the hydrogen to produce methane. In conjunction with the University of Tokyo’s Frontier Research Center for Energy and Resources (FRCER) School of Engineering, we hold a chair on the engineering behind sustainable carbon recycling systems at the center.
