CO2 Capture using Inorganic Precipitation Associated with Algal Photosynthesis
Introduction Global warming is rapidly becoming a critical concern for the entire planet as increasing amounts of greenhouse gases, such as CO2, continuously pump into the atmosphere. One technique suggested to mitigate these effects is carbon capture and storage (CSS) or carbon sequestration. This is a general process by which gaseous CO2 from large point source producers is somehow isolated and placed into long-term storage as either CO2 or as stable mineral carbonates. Unfortunately, specific implementations of this process are typically prohibitively expensive. Technology Description Professor Taub at the University of Washington has developed an efficient and effective methodology for using algae to convert CO2 into insoluble mineral carbonates. This process significantly modifies algae’s natural capacity for carbon sequestration, and it could be adapted for use with a variety of CO2 sources. Business Opportunity The ability to effectively and efficiently sequester carbon from the atmosphere presents tremendous opportunities for mitigating the looming effects of global warming. Large point sources of CO2 emissions are the primary targets for this technology, which promises lower cost than other capture processes and more options for the improved negotiation of emissions cap and trading regulations. This technology could be one important part in the reversal of global warming. Stage of Development A working methodology for this technology is in development. Intellectual Property Position The UW is currently reviewing this technology for worldwide patent protection.
