Retrofittable onboard carbon capture systems helping the shipping industry reduce emissions today.
Seabound is a climate technology company developing onboard carbon capture systems for commercial shipping. The company enables vessel operators to capture carbon dioxide emissions directly from ship exhaust systems, providing an immediate pathway for maritime decarbonization without waiting for alternative fuels or fleet replacement cycles.
Founded by entrepreneur and climate leader Alisha Fredriksson, Seabound addresses one of the hardest sectors to decarbonize: global shipping. Maritime transportation is responsible for approximately 3% of global greenhouse gas emissions and carries roughly 90% of world trade, making it a critical industry for climate action.
Seabound's technology captures CO₂ from a ship's exhaust stream and converts it into stable carbonate pebbles through a proprietary process. These solid materials can then be safely offloaded at port and transported for permanent storage or industrial reuse. The system is designed to integrate with existing vessels, allowing shipowners to reduce emissions without replacing engines or waiting for large-scale adoption of alternative fuels.
The company's fully automated system can capture between 25% and 95% of a vessel's carbon emissions, depending on deployment requirements. By creating a practical retrofit solution, Seabound provides shipping companies with a tool to comply with emerging climate regulations while reducing operational climate impact.
Backed by leading climate investors and supported by major shipping industry partners, Seabound is helping accelerate the transition toward a lower-carbon maritime sector.
Seabound reduces greenhouse gas emissions from the global shipping industry by capturing carbon dioxide directly onboard vessels before it enters the atmosphere.
Rather than relying solely on future fuel transitions, the company enables immediate emissions reductions using retrofit technology that works with existing fleets. Captured carbon is converted into stable carbonate materials that can be safely transported and permanently stored.
