Seabound is developing a uniquely cost-effective onboard carbon capture system that can be retrofitted onto existing or new ships to reduce up to 95% of their CO2 emissions. Leveraging a second-generation technology called calcium looping, the system uses a material called calcium hydroxide (also known as lime) to chemically react with the CO2 in a given ship's exhaust gas to form calcium carbonate (also known as limestone). The resulting limestone pebbles are temporarily stored onboard in the solid phase and offloaded ashore. On land, the pebbles are reprocessed into lime (calcination), which are reused for further onboard carbon capture. The extracted pure CO2 can be sold for synthetic fuel production or can be fed into geological sequestration. With the funding, we will execute a commercially-scaled onboard demonstration, advance our plans for plants that will regenerate CO2-absorbing lime, and finalize manufacturing readiness for scaling to 100+ units annually.
