Denbury/ExxonMobil – Jackson Dome CO2 Field (Mississippi)

Jackson Dome volcanic CO2 reservoir in central Mississippi — the largest natural CO2 source in the eastern United States. Geologically trapped CO2 of volcanic origin (not combustion byproduct); exceptionally pure (>95% CO2). Historically operated by Denbury Resources; Denbury acquired by ExxonMobil in November 2023 for $4.9B as part of ExxonMobil's carbon capture strategy. The Jackson Dome CO2 was historically the backbone of US food-grade CO2 supply in the Southeast before being increasingly allocated to Enhanced Oil Recovery (EOR) in Mississippi and Alabama oil fields. ExxonMobil's acquisition of Denbury reframes Jackson Dome as CCS infrastructure rather than food supply — creating long-term competition between food industry CO2 needs and EOR/CCS uses for the same geologic resource. Note: Facility company_id set to air-products as a placeholder — the actual owner is ExxonMobil via Denbury; no facility edge linked since ownership structure differs from distributor.
