A Cheap & Easy Way To Reduce Carbon Emissions From Ships - CleanTechnica

The article discusses the significant carbon dioxide and pollutant emissions produced by ocean-going ships, which exceed those from air travel. Traditional marine engines burn bunker oil, a thick, cheap residual fuel that also serves as the engine’s lubricant, making it difficult and costly to switch to cleaner fuels or retrofit ships with modern engines. Such retrofits are expensive—costing upwards of half a million dollars—and require ships to be out of service for extended periods, creating financial disincentives for shipowners to adopt cleaner technologies. A promising solution comes from a London-based company called Seabound, which has developed an onboard carbon capture system ready for immediate deployment. The system uses steel containers filled with quicklime pellets that chemically react with the ship’s exhaust CO2, converting it into limestone and thereby reducing emissions. Quicklime is a widely produced industrial material, making this approach scalable and practical. The technology was conceived by entrepreneur Alisha Fredriksson, inspired by climate change reports, who adapted existing industrial carbon capture
