MOVING CARBON TO RESTORE THE EARTH
Our Projects
T-RICH
Tampa Regional Intermodal Carbon Hub
Aptamus was awarded funding from the U.S. Department of Energy (DOE) in September 2024 to conduct a pre-FEED study of an intermodal CO2 hub in the Port of Tampa Bay. The study considered CO2 liquefaction to prepare it for tranport on a marine vessel, as well as 30,000 m3 of temporary storage.
COAST20
Carbon Ocean And Storage Transport 20
Aptamus has conditionally approved funding from the U.S. Department of Energy (DOE) to expand on the T-RICH pre-FEED study to more fully develop T-RICH, as well as fully define the CO2-carrying ship and the discharge and regassification terminal in Louisiana.
OCCS
Onboard Carbon Capture & Storage
Aptamus completed a pre-FEED study funded by the U.S. Maritime Administration (MARAD). The study looked at the installation of a carbon capture & storage plant onboard one of OSG’s existing tankers, capable of capturing approximately half of the tanker’s CO2 emissions.

Our Company
Aptamus Carbon Solutions is committed to securing a sustainable future by providing safe and reliable marine carbon transport and storage solutions. We will partner with carbon emitters to provide a full-service solution for the disposal of their captured CO2 by transporting it in our specially designed CO2 ships to safe, long-term storage locations in Louisiana and Texas. Our service provides a water-based, cost-effective solution for large emitters located in regions such as Florida where the geology is not conducive to carbon sequestration, and where new long-distance pipelines to suitable sequestration sites are not feasible or cost-effective.
Aptamus enables our customers to reduce their negative environmental impact and contributes to a healthier, sustainable planet. Our focus on safety, transparency, and operational excellence is built on four decades of maritime transportation experience with parent company Overseas Shipholding Group (OSG, www.osg.com). This ensures that every cargo is handled with the utmost care and responsibility, and our actions adhere to the highest ethical standards.
