The report evaluates the potential for offshore carbon capture and storage (CCS) in the US mid-Atlantic to compensate for limited onshore capacity. Using the SimCCS modeling toolset, the study identifies 199 facilities across 15 industry sectors with a total of 31.47 Mt of annual capturable CO2. It finds that while offshore storage capacity is vast—estimated at 621,221 MtCO2 across 125 candidate sites—the costs are significantly higher than onshore benchmarks, ranging from 95.5 to 147.9 $/tCO2. This cost disparity is primarily driven by offshore pipeline installation and storage expenses. The analysis suggests that capturing the full 31.47 MtCO2 would require a 7,789 km branched pipeline network and that emission prices between $95.5 and $103.5 per tonne could incentivize initial capture efforts.
