The NCCC, operated by Southern Company Services, includes a post-combustion carbon-capture facility that allows testing and integration of advanced CO 2-capture technologies using flue gas from Alabama Power’s Gaston power plant Unit 5, an 880 MW pulverized coal unit. Pilot-scale testing of the technology, using actual flue gas, began in late January at DOE’s National Carbon Capture Center (NCCC) in Wilsonville, Ala., and will continue for two to three months. Successful testing at pilot scale (1 MW-electric) will be a major step toward meeting the Department program’s goal of capturing more than 90 percent of CO 2 from flue gas at a cost of $40 per metric ton of CO 2 captured and compressed to 2,200 psig (pounds per square inch gauge). The MTR membrane separation process has already completed 7,500 hours of small-scale (0.05 MW-electric) testing using actual flue gas. In addition, the membrane system does not use hazardous chemicals, so there are no emissions or disposal issues it uses less water than other capture technologies and the membrane has no moving parts. Challenges and Future Development of Carbon Capture Technology. That means the membrane area can be reduced, cutting down the cost and size of the system. Lock Hei Ngu, in Reference Module in Earth Systems and Environmental Sciences, 2022. Cost-effective carbon capture and storage from fossil-based power generation has been cited by some national and international experts as a critical component for arresting the rise in atmospheric CO 2 concentrations.Īccording to DOE, the Polaris system is 10 times more permeable to CO 2 than conventional gas-separation membranes. The retrofit utilized a post-combustion amine absorption technology. In 2010, SaskPower committed to retrofitting the lignite -powered Unit 3 with a carbon capture unit. According to DOE, it has the potential to support the reduction of greenhouse gas emissions from coal-fired power plants while minimizing the increase in electricity price. Boundary Dam Power Station, owned by SaskPower, is a coal fired station originally commissioned in 1959. The project, managed by the DOE Office of Fossil Energy’s National Energy Technology Laboratory (NETL) is the largest-scale CO 2 membrane technology in the Department’s research portfolio.
