Sanchez, Daniel L.; Johnson, Nils; McCoy, Sean T.; Turner, Peter A.; Mach, Katharine J. (2018): Near-term deployment of carbon capture and sequestration from biorefineries in the United States. In Proceedings of the National Academy of Sciences of the United States of America. DOI: 10.1073/pnas.1719695115.

„Here, we evaluate low-cost, commercially ready CO₂[nbsp]capture opportunities for existing ethanol biorefineries in the United States. The analysis combines process engineering, spatial optimization, and lifecycle assessment to consider the technical, economic, and institutional feasibility of near-term carbon capture and sequestration (CCS). Our modeling framework evaluates least cost source–sink relationships and aggregation opportunities for pipeline transport, which can cost-effectively transport small CO₂[nbsp]volumes to suitable sequestration sites; 216 existing US biorefineries emit 45 Mt CO₂[nbsp]annually from fermentation, of which 60% could be captured and compressed for pipeline transport for under $25/tCO₂.“
