Aptamus Carbon Solutions and LBC Tank Terminals Announce Joint Development Agreement for CO2 Marine Terminals, Completing CO2 Supply Chain from Port Tampa Bay
May 15, 2025 (Tampa, Florida) – Aptamus Carbon Solutions LLC (Aptamus), a subsidiary of Overseas Shipholding Group, Inc. (OSG), a leading provider of energy transportation, announced it has reached an agreement for the design and engineering of a CO2 discharge terminal at LBC Tank Terminals’ (LBC) facility in Baton Rouge, Louisiana. LBC, an international operator of bulk liquid storage terminals, brings operational expertise and strategically located infrastructure essential to supporting large-scale CO₂ transport and storage. This agreement, in addition to a potential partnership with Port Tampa Bay to develop a CO2 loading terminal, forms a complete supply chain solution for the collection, processing, and marine transportation, for captured CO2 from Florida emitters for permanent sequestration in the northern Gulf of Mexico region in Texas and Louisiana.
“This agreement with LBC provides further certainty and confidence in our Company’s business case. 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,” said Jeffrey Ross Williams, President of Aptamus. “Our solution will accelerate the adoption of carbon capture by Florida’s power generating companies, and the reputation of our partners Port Tampa Bay and LBC can be relied on to provide the best solution for the ultimate disposal of Florida’s CO2 emissions, creating tremendous health, economic, and environmental benefits to the residents and the business community of Florida,” Williams added.
Paul Anderson, Port Tampa Bay President and CEO, said, “Our partnership with Aptamus and OSG opens the possibility for job creation and environmental and health impacts that benefit the Tampa Bay region and beyond. This potential partnership is an example of our maritime community’s diversification and our commitment to a resilient and sustainable future. We welcome plans for a CO₂ terminal.”
“LBC is thrilled to join forces with such great partners as OSG and Port of Tampa Bay on this critical decarbonization infrastructure project,” said Jeff Dewar, SVP Americas, LBC Tank Terminals. “As an international operator with a proven track record in liquid bulk logistics, LBC is uniquely positioned to play a leading role in the development of scalable CO₂ infrastructure. This partnership reflects our long-term commitment to enabling low-carbon solutions through strategic investments, operational excellence, and the delivery of safe and sustainable storage solutions across Florida, Louisiana, and beyond.”
The proposed CO2 supply chain feasibility study is intended to be funded in part by two grants from the U.S. Department of Energy. OSG was awarded one grant for the design and engineering of the collection, liquefaction, and loading terminal at Port Tampa Bay, which is intended to serve as the primary hub for captured carbon in Florida. The greater Tampa region alone emits more than 30 million tons of CO₂ annually, driven largely by regional electricity generation.
OSG was also selected to be awarded a second grant to perform a FEED-level design and engineering study of the CO2 storage and transportation supply chain, known as the Carbon Ocean and Storage Transport 20 (COAST20) project. This includes the design of a 20,000 ton tank vessel and its cargo management system, the potential load terminal at Port Tampa Bay, and the LBC discharge terminal at Baton Rouge, LA. The LBC terminal is adjacent to an existing CO2 pipeline network for delivery to Class VI injection wells. The northern Gulf of Mexico region including the onshore areas of Texas and Louisiana have the largest confirmed capacity for safe, permanent underground sequestration of CO2 in the nation.
