STAX Engineering

STAX Engineering is transforming how the maritime industry addresses at-berth emissions, delivering immediate air quality improvements for local communities and compliance with evolving emissions standards. Launched in 2024, STAX has become the first fleet approved by the California Air Resources Board (CARB) to provide emissions capture and control across all major vessel types – container ships, auto carriers (ro-ro), and tankers.

The company's patented, flexible exhaust capture system connects directly to vessels without requiring modifications, even in the most congested ports. STAX's technology removes 99% of particulate matter and 95% of nitrogen oxides, enabling greener supply chains for shippers. The company has treated more than 2,000 vessels for 25,000+ hours, capturing over 200 tons of pollutants–and counting.

Building on this success, STAX recently demonstrated a first-of-its-kind fully integrated emissions and carbon capture solution earlier this year. Together with its UK partners, STAX plans to deploy the comprehensive solution in the Port of Southampton with support from the UK Government’s Clean Maritime Demonstration Competition. In early 2025, STAX secured $70 million to scale operations across California, the US, and abroad. STAX is well-positioned to meet the growing global demand and accelerate progress toward a zero-emissions future.
