- STAX Engineering and Seabound showcased the first integrated system that captures both air pollutants and carbon emissions directly from ships without requiring onboard retrofits.
- The system successfully removed 99% of particulate matter, 95% of nitrogen oxides, 95% of CO₂, and 90% of sulfur during real-world trials at the Port of Long Beach.
- Supported by CARB and AQMD, the project is expanding internationally, with plans to deploy the solution at the Port of Southampton in the UK.
STAX Engineering and Seabound have successfully demonstrated a pioneering integrated emissions and carbon capture solution at the Port of Long Beach, reads an official release.
This collaboration offers a comprehensive approach to reducing both criteria pollutants and greenhouse gases from maritime vessels, addressing the pressing need for sustainable solutions in the shipping industry.
Innovative Integration for Cleaner Shipping
The demonstration featured a combined system mounted on a STAX barge servicing a roll-on/roll-off (RoRo) vessel from Wallenius Wilhelmsen. STAX’s mobile emissions control unit effectively removed 99% of particulate matter (PM) and 95% of nitrogen oxides (NOx) from the vessel’s exhaust. Subsequently, Seabound’s onboard carbon capture technology isolated and stored up to 95% of carbon dioxide and 90% of sulfur, releasing purified exhaust back into the atmosphere. This end-to-end solution operates without requiring retrofits or significant structural changes to existing ships or port facilities.
Regulatory Support and Industry Impact
The initiative aligns with stringent emissions regulations set by the California Air Resources Board (CARB) and the International Maritime Organization’s goal of a 20% reduction in carbon emissions by 2030. Funded by CARB and the South Coast Air Quality Management District (AQMD), the project underwent three trial phases beginning in March 2025, servicing clients like Wallenius Wilhelmsen and NYK. Independent verification by Yorke Engineering confirmed the system’s efficacy.
Future Expansion Plans
Building on this success, STAX and Seabound plan to scale their solution internationally, including a collaboration with Associated British Ports to implement the technology at the Port of Southampton in the UK. This expansion aims to provide maritime operators worldwide with practical tools to meet environmental regulations and advance decarbonization efforts.
