MAMII Report Highlights Solutions to Curb Maritime Methane Emissions

In the UK, the Methane Abatement in Maritime Innovation Initiative (MAMII) released a report from Safetytech Accelerator showcasing innovative solutions to mitigate methane slip from LNG-fueled ships, of which available technology solutions for fugitive leaks are described in the report as ‘low hanging fruit’.

CDTi’s Lean Methane Oxidation Catalyst, a passive device installed within exhaust flows to curb methane slip, achieves substantial conversion rates at 300-500°C. Plenesys’ plasma torch technology, which breaks up methane molecules in exhaust stacks, offers promising results with low maintenance requirements. Additionally, Rotoboost’s system leverages LNG to produce hydrogen fuel onboard, reducing methane slip through hydrogen blending.

The report highlights specific engine types for these technologies. Low-pressure two-stroke engines benefit significantly from catalytic abatement technologies, while four-stroke engines see optimal results with both catalytic and plasma solutions. High-pressure two-stroke engines, on the other hand, would benefit more from solutions applied to auxiliary engines.

MAMII calls for robust regulatory frameworks to incentivize technology adoption, emphasizing the integration of methane abatement into CO₂e regulations. The initiative’s collaborative efforts with industry leaders aim to standardize methane measurement and accelerate the deployment of these technologies, ensuring the maritime industry meets international climate targets and significantly reduces its methane footprint.
