Summary:
STAX Engineering and Seabound unveil a 'first-of-its-kind' emissions and carbon capture solution.
The solution successfully passed trials and is set for deployment with Associated British Ports (ABP).
Showcased at the Port of Long Beach, the system captures harmful pollutants and CO2 from vessels.
$70 million in funding secured by STAX to fuel further carbon capture integration and expansion.
Seabound is launching its first full-scale commercial carbon capture systems this year.
Innovative Collaboration in Carbon Capture
STAX Engineering, a California-based leader in maritime emissions capture, and Seabound, a UK-based firm specializing in onboard carbon capture, have introduced a 'first-of-its-kind' fully integrated emissions and carbon capture solution. This end-to-end modular system has successfully passed its final trial and is set for deployment with Associated British Ports (ABP).

Real-World Testing at Port of Long Beach
During a recent event at the Port of Long Beach, the two companies showcased their innovative emissions-reduction technologies. The system, mounted on a STAX barge, effectively serviced an at-berth roll-on roll-off (RoRo) vessel from Wallenius Wilhelmsen (WWL), filtering harmful pollutants such as particulate matter (PM) and nitrogen oxide (NOx) while capturing carbon dioxide from the vessel's exhaust.
Milestone in Port Emissions Reduction
This breakthrough is a significant step toward reducing port emissions, especially as regulations aim to address the billions of tons of carbon emissions produced by the industry. Mike Walker, CEO of STAX, emphasized the importance of this moment, stating:
"Today marks a landmark moment in our journey toward a zero-emissions future."
Alisha Fredriksson, Co-founder and CEO of Seabound, expressed that their collaboration shows that effective, scalable emissions solutions are achievable now.
Partnership with ABP for a Sustainable Future
In March 2025, ABP welcomed STAX and Seabound into its Energy Ventures Accelerator, aimed at exploring clean energy solutions to combat emissions in ports nationwide, striving for Net Zero by 2040.
Paul J. G. Rennie, OBE, highlighted the significance of UK-US partnerships in transforming global industries through innovative technology that supports cleaner supply chains.
Advanced Technology Integration
The integrated system combines STAX's mobile emissions control unit, which removes 99% of PM and 95% of NOx, with Seabound’s carbon capture technology. Operating directly at the vessel’s exhaust, STAX technology purifies the exhaust gas before directing it through Seabound’s capture unit, isolating and storing up to 95% of carbon and 90% of sulfur.
Since its inception in early 2024, STAX has significantly contributed to compliance with CARB regulations in major ports, capturing over 126 tons of pollutants and recently securing $70 million in funding for further carbon capture integration and expansion.
Looking Ahead
Founded in late 2021, Seabound is set to launch its first full-scale commercial carbon capture systems this year, following a successful demonstration of capturing CO2 at approximately 80% efficiency on a container vessel.
