At STAX, we’ve created the most advanced emissions capture technology for the maritime industry with an ability to capture up to 99% of pollutants such as nitrogen oxides (NOx) and particulate matter (PM)—servicing all vessel configurations and requiring no retrofitting. Now, we’re taking the next step by evaluating best-in-class carbon capture solutions. Through our first carbon capture trials with Seabound, we’re working to create the most comprehensive emissions capture and control system on the market.
The Next Evolution in Maritime Emissions Control
Last week, we announced a partnership with UK-based carbon capture company Seabound. Founded in 2021, Seabound has quickly emerged as a leader in modular carbon capture technology for ships. Their system is ocean-ready today, providing shipowners with a practical way to reduce their emissions without waiting for alternative fuels or costly fleet overhauls. Through this collaboration, we are trialing the integration of Seabound’s technology into the STAX system—the first step toward a fully integrated solution that tackles both harmful pollutants and greenhouse gas emissions from shipping.
How It Works
Step 1: STAX connects to a ship’s exhaust pipe(s) and filters out 99% of PM and 95% of NOx—pollutants that harm local environments and the health of surrounding communities—releasing a purified gas.
Step 2: The purified gas is then directed into Seabound’s capture unit, which isolates and stores the ship’s carbon and sulfur emissions before the cleaned exhaust gas enters the atmosphere, reducing the vessel’s overall greenhouse gas footprint.
This combined system builds on STAX’s proven emissions control technology while integrating Seabound’s carbon capture solution, making it the most scalable, efficient emissions reduction technology available for ports and ships worldwide. Trials will begin this spring, and we anticipate sharing the findings later this year.
Why This Matters
Shipping is responsible for roughly 3% of global CO2 emissions—and without action, that number is only going to rise. Regulators like the International Maritime Organization (IMO) and the California Air Resources Board (CARB) are enforcing stricter emissions standards, meaning shipowners need practical, immediate solutions to stay compliant.
Seabound’s modular carbon capture units offer a game-changing approach, allowing operators to capture CO2 directly from their exhaust instead of waiting for alternative fuels or major fleet upgrades. With STAX’s emissions control system now incorporating carbon capture, we provide a comprehensive solution that tackles both air pollution and greenhouse gas emissions—something no other system on the market does today.
Expanding Our Impact
100 tons of pollutants. As CARB’s new regulations took effect on Jan. 1, 2025, our technology provides a crucial pathway to compliance for vessel operators. By integrating carbon capture into our emissions control system, we are extending our impact and helping decarbonize the industry more rapidly.
Beyond maritime emissions, STAX is exploring broader applications of our technology, including opportunities in data centers and other industries with high-emissions footprints. Our partnership with Seabound is just the beginning of a larger effort to create cleaner, more sustainable solutions for multiple hard-to-abate sectors.
What’s Next?
With trials already underway, we are focused on fine-tuning the integration of Seabound’s system with STAX technology. In the near future, we plan to expand deployments to more ports, giving vessel owners and operators a practical and scalable path to making a measurable impact on global carbon reduction efforts.
Maritime emissions control isn’t something that can wait—and with STAX and Seabound working together, we’re proving that cleaner shipping is possible today, not years down the line.
