In a groundbreaking development, STAX Engineering from California and Seabound based in the UK have showcased a novel integrated emissions and carbon capture solution. The innovative modular system has successfully completed its final trial and is now poised for deployment at Associated British Ports (ABP). Demonstrated at the Port of Long Beach, the joint technologies effectively reduced emissions from a Wallenius Wilhelmsen vessel, capturing harmful pollutants and carbon dioxide from its exhaust.

This achievement holds significant importance in the context of reducing port emissions worldwide, especially as regulations address the industry’s substantial carbon footprint. STAX CEO Mike Walker hailed the collaboration with Seabound as a crucial step towards a zero-emissions future, with plans to expand carbon capture capabilities across fleets. Seabound’s CEO Alisha Fredriksson emphasized the practicality and scalability of their emissions solutions, highlighting the positive impact on global maritime sustainability.

The partnership between STAX, Seabound, and ABP, facilitated through the Energy Ventures Accelerator program, underscores the influence of UK-US collaborations in driving innovation and sustainability in port operations and supply chains. The integrated system combines STAX’s emissions control unit with Seabound’s carbon capture technology, offering a comprehensive approach to reducing pollutants and capturing carbon from vessel emissions.

Since its inception, STAX has made significant strides in emissions control, achieving CARB compliance in major ports and capturing substantial pollutants. The company’s recent funding injection will support further carbon capture integration and international expansion efforts. On the other hand, Seabound, established in 2021, has successfully demonstrated its carbon capture system onboard vessels and is gearing up for commercial deployment this year.
