The Future of Emission Control for Tankers at California Ports

The California Air Resources Board (CARB) has taken a significant step forward in reducing emissions from ocean-going vessels by issuing an executive order that authorizes the expanded use of the carbon capture barge service provided by STAX Engineering. This move comes at a crucial time as CARB’s Ocean-Going Vessels at Berth regulation has come into effect for tankers at the Ports of Los Angeles and Long Beach as of January 1, with plans to extend to all California ports by 2027.

As crude oil, product, and gas tankers play a vital role in California’s maritime trade, the inability to use shore power due to safety concerns has posed a challenge in meeting emissions regulations. However, with the introduction of STAX Engineering’s innovative technology, tankers now have a practical solution to comply with the new standards and improve air quality for communities in the vicinity.

STAX Engineering’s Emission Capture and Control System

STAX’s mobile, barge-based emissions capture and control system offer a seamless solution for vessels to reduce emissions without the need for costly retrofits or modifications. The system connects directly to the vessel’s exhaust system, capturing up to 99 percent of particulate matter and 95 percent of nitrogen oxides (NOx) emissions without requiring additional power.

Since early 2024, STAX has been servicing vessels at California’s main ports, treating a total of 1,192 vessels and capturing 190 tons of pollutants. With a focus on tankers, the company has already dedicated nearly 1,000 hours to improving emissions from these essential vessels.

Expanding Services and International Collaboration

Under the recent executive order, STAX has received approval for four barges to enhance its emission control services. The company has secured contracts with prominent tanker berths at key terminals in Los Angeles and Long Beach, with plans to expand its presence to Northern California by 2027.

Additionally, STAX Engineering has garnered recognition on the international stage, securing funding from the UK government for its PortZero project. This collaboration with industry partners aims to further develop emission control solutions for maritime vessels beyond California, showcasing the company’s commitment to sustainable practices on a global scale.

As STAX Engineering continues to innovate in the field of emission control for tankers and other large vessels, the future looks promising for a cleaner and more sustainable maritime industry in California and beyond.
