Eisaman, Matthew D.; Rivest, Jessy L.B.; Karnitz, Stephen D.; Lannoy, Charles-François de; Jose, Arun; DeVaul, Richard W.; Hannun, Kathy (2018): Indirect ocean capture of atmospheric CO2. Part II. Understanding the cost of negative emissions. In International Journal of Greenhouse Gas Control. DOI: 10.1016/j.ijggc.2018.02.020.

„An analysis was performed of the economic feasibility of a novel platform of candidate NETs – indirect ocean capture (IOC) – through industry-validated economic and chemical process modeling supported by inputs from a prototype system. This manuscript details the development of a high-fidelity estimate of the cost of avoided CO₂ emissions from this NET by coupling scaled experiments to economic analyses. For the lowest-cost scenario of co-location with a desalination plant, a likely cost of $604 per metric ton of avoided CO₂ (tCO₂) was found, and a best-case cost of $373/tCO₂.“
