STAX Engineering, Inc. product offering
Product offeringCore offering
STAX Engineering provides mobile barge-based, land-based, and truck-based emissions capture and control as a service to terminal operators, shipping fleets, and data centers. Its CARB-approved system uses proprietary XCAP exhaust capture arms and STAXbox purification units to remove 99% of particulate matter and 95% of nitrogen oxides from vessel exhaust at berth, with no vessel retrofits or port infrastructure required. The offering is delivered through multi-year service contracts priced on a usage-based hourly model.
Product overview
STAX Engineering offers a unified emissions capture and control solution consisting of three integrated components: the XCAP Exhaust Capture System (placement arm with 250+ foot reach), the STAXbox Purification System (converts pollutants to harmless CO2 and water vapor), and mobile barge/truck deployment platforms. The company provides barge-based, land-based, and mobile service delivery models for maritime and data center industries. All components work together as a complete emissions treatment system, with the capture arm collecting exhaust and channeling it through purification units before releasing cleaned gas. The solution is CARB-approved for container ships, auto carriers (ro-ros), and tankers, and the STAXtruck extends the technology to data center backup generators.

STAX Engineering, Inc. competitors and assessment
Company assessmentDirect peers
- Wärtsilä: Wärtsilä is a Finnish marine technology leader that provides exhaust gas cleaning systems (scrubbers), shore power, and emissions reduction solutions for commercial vessels. They compete with STAX in the maritime emissions control space with substantially greater scale and global port relationships, though STAX's mobile barge approach differentiates from Wärtsilä's vessel-retrofit solutions.
- ABB Marine & Ports: ABB provides shore power (cold ironing) solutions and port electrification infrastructure that competes with STAX's mobile emissions capture approach. Both target port-side emissions reduction at berth, with ABB favoring fixed infrastructure investments while STAX offers flexible barge-based service without port capex requirements.
- Yara Marine Technologies: Yara Marine provides shore power and FuelOpt energy optimization systems for commercial shipping. They are a direct competitor in the port-side emissions space, with established relationships across major shipping lines but a fixed-infrastructure approach that contrasts with STAX's mobile barge model.
- Kongsberg Maritime: Kongsberg Maritime provides integrated vessel systems including emissions monitoring, engine controls, and digital fleet management for commercial shipping. They are an adjacent competitor in maritime emissions reduction with stronger software/data capabilities but no at-berth emissions capture offering comparable to STAX.
- Cavotec: Cavotec specializes in shore power connection systems and port electrification equipment for container terminals, cruise, and commercial vessels. They directly compete with STAX by enabling alternative compliance pathways through fixed shore power infrastructure, but lack a mobile emissions capture product.
- Alfa Laval: Alfa Laval provides marine exhaust gas cleaning systems (scrubbers), heat exchangers, and separation equipment widely adopted across global shipping fleets. They are a major incumbent in marine emissions control with extensive OEM relationships but focus on vessel-retrofitted solutions rather than port-side capture.
Broad incumbents
- Caterpillar Marine: Caterpillar Marine supplies marine propulsion engines, generators, and emissions aftertreatment systems across commercial and offshore vessels. They are a broad incumbent in the marine power and emissions space with substantially greater capital, dealer networks, and installed base, though their focus is engine-side solutions rather than port-side capture.
- Rolls-Royce Power Systems (mtu): Rolls-Royce Power Systems (mtu brand) supplies marine propulsion, diesel gensets, and integrated power solutions for commercial vessels and yachts. They are a broad incumbent in marine power with potential to develop competing emissions solutions, and also serve the data center backup power market where STAXtruck competes.
- Cummins: Cummins provides marine diesel engines, generators, and emissions aftertreatment systems for commercial vessels and data center backup power applications. They are a broad incumbent with substantial scale, though their focus is on engine manufacturing rather than post-combustion emissions capture services.
Emerging players
- Bloom Energy: Bloom Energy provides solid oxide fuel cell solutions for data center backup power and distributed generation. They represent an emerging alternative to diesel backup generators in the data center market where STAXtruck competes, offering on-site clean power generation instead of post-combustion emissions capture.
