e1 Marine, STAX Engineering partner on capturing emissions

The duo will collaborate to develop emissions capture and control technology to aid the decarbonisation of ocean-going vessels.

US-based marine technology firm e1 Marine’s methanol-to-hydrogen power systems will be used with compatriot STAX Engineering's emissions capture and control technology.

The California Air Resources Board (CARB) and the South Coast Air Quality Management District (AQMD) are funding this project. 

Under the project, e1 Marine will install its power systems on STAX’s barges for the demo scheduled in early 2025. The power system will be combined with STAX's capture and control technology and be used for onboard power needs.

The methanol-to-hydrogen power system uses hydrogen fuel cells and can provide around 100kW (kilowatt) to multi-MW (megawatt) output, e1 Marine claims. The system comes with a methanol reformer, a device used in fuel cell technology to produce pure hydrogen gas through a reaction of a methanol and water steam mixture.

STAX’s technology captures exhaust gases such as nitrogen oxides (NOx) and particulate matter (PM) from a vessel’s funnel by connecting it to a barge, a small flat-bottomed ship, or a land-based exhaust-gas treatment system via steel pipes and hoses.

The technology can remove 99% of emitted particulate matter (PM) and 95% of emitted oxides of nitrogen (NOx), STAX claimed.

STAX has entered into service agreements at major California ports, including Los Angeles, Long Beach, Hueneme, Benicia, Richmond and Oakland to capture exhaust emissions.
