By Alabama NewsCenter Staff A pioneering technology that can permanently store carbon dioxide (CO2) in concrete blocks has gone through successful testing at the Alabama-based National Carbon Capture Center (NCCC). CarbonBuilt and the NCCC, located next to Alabama Power’s Plant Gaston in Wilsonville, announced the completion of the multiweek test of carbon utilization and concrete production technology. The test successfully injected CO2 from the flue gas streams of the NCCC’s natural gas testing system and Plant Gaston’s coal-fired generating unit into more than 5,000 concrete blocks, where the carbon is now “stored for good,” according to a news release.
