Description

There is an urgent need to significantly reduce CO2 emissions from coal burning power plants. Current CO2 capture technologies are too expensive and not economically viable. A new technology that can capture ~90% of the CO2 and significantly reduce the cost of capture is required for commercial viability. Statement of How this Problem is Being Addressed:This project is aimed at the development of an advanced algae technology that can enable 90% of the CO2 from coal based power plants to be captured and converted to liquid bio-fuels and other high value products. Generation of high value co-products creates substantial added revenue which can potentially reduce the net cost of CO2 capture to <$10/ton.Phase1 Accomplishments:In Phase1 the technology feasibility of achieving >80% CO2 capture from simulated flue gas was demonstrated using discrete components. The dewatering technology was advanced and a new membrane developed. Presence of key co-products validated.Plans for Phase 2 Project:In Phase2, the technology will be advanced and positioned for future testing in relevant environments. A lab scale pilot system to demonstrate the core technology for high efficiency carbon capture at high productivity will be built and operated. The new technology for dewatering will be advanced and membrane modules made. The technology for producing high value co-products will be demonstrated at lab scale. Techno-economic analysis will be refined.Commercial Applications and Other Benefits:Commercial applications of the new technology include CO2 capture from coal power plants and other fossil fueled industries, production of liquid bio-fuels, food and nutraceuticals. This will greatly reduce CO2 emissions and consumption of petroleum. About 99% of the water used is recycled thus greatly reducing fresh water consumption. By enabling the large new applications mentioned above, it can create new industries and jobs.
