Aptamus Carbon Solutions, a subsidiary of Overseas Shipholding Group (OSG), has signed a joint development agreement with LBC Tank Terminals to design a CO2 offloading terminal in Baton Rouge, Louisiana.
This facility will serve as the endpoint of a planned carbon transport route linking Florida emitters to permanent storage sites along the Gulf Coast.
Together with a proposed CO2 loading terminal at Port Tampa Bay, this agreement completes a full marine supply chain to collect, liquefy, transport, and store captured carbon.
LBC’s Baton Rouge terminal is located next to an existing pipeline network that delivers CO2 to Class VI injection wells for long-term sequestration.
The project is expected to be partially funded by two US Department of Energy grants.
One supports the design of the Port Tampa Bay terminal, which will act as Florida’s main carbon hub, while the second backs engineering studies for the full COAST20 system — covering vessel design, cargo systems, and terminal infrastructure.

The Tampa Bay region emits more than 30 million metric tons of CO2 annually, and the Gulf Coast has the country’s largest confirmed underground storage capacity, positioning this initiative as a key step toward scalable carbon capture and sequestration in the US.
“This agreement with LBC provides further certainty and confidence in our company’s business case,” said Jeffrey Ross Williams, President of Aptamus.
“With partners such as LBC and Port Tampa Bay, Aptamus is in a better position to create an efficient, cost effective, and seamless supply chain for the temporary storage, processing, and ocean shipment of captured CO2 from one of the nation’s highest emitting states.”
