Carbon Storage Potential in Offshore Nova Scotia, Canada

Carbon management is a growing global industry that is critical to achieving emissions reduction targets while presenting new economic opportunities. Atlantic Canada is well-positioned to lead in this field through its offshore geologic storage resources and an emerging marine carbon dioxide removal (mCDR) sector. With a relatively small emissions profile and significant storage potential, the region could serve as a carbon sink for national and international efforts. Realizing this potential requires coordinated development and further geological and marine research. Net Zero Atlantic is advancing this work by leading technical studies and supporting initiatives. The Nova Scotia Offshore CCS Atlas is refining earlier estimates of carbon storage potential on the Scotian Shelf to support future project planning. This includes geologic and reservoir engineering analyses, probabilistic assessments, and digital models, with publication planned for 2027. Concurrent mCDR research, including Ocean and River Alkalinity Enhancement, is progressing through academic and start-up collaborations. Insights from a 2024 CCS Roundtable have informed the development of a regional Roadmap outlining key actions to enable CCS deployment. With storage potential exceeding local needs, Atlantic Canada has the potential to become a carbon management hub serving eastern Canada, the U.S., and Europe.
