Technology Description:
Hydrolytic softening is a lower-cost process to remove CO2 from the oceans. It has similarities to processes at conventional water treatment facilities, which mix hydrated lime to “soften” water by precipitating dissolved inorganic carbon as calcium carbonate. In hydrolytic softening, however, instead of a consumptive use of lime, the calcium carbonate is decomposed. This releases CO2 gas for sequestration or industrial use and regenerates the lime for continued cycles of carbon removal. Hydrolytic softening can reduce energy input costs for CO2 removal by 77% compared to state-of-the-art methods based on sodium chloride salt splitting using bipolar membrane electrodialysis.
