In its first year, MAMII has focused on identifying and evaluating new technologies to monitor and reduce methane emissions from LNG-fuelled vessels, with a particular emphasis on measuring unburned methane in the exhaust stack ie, ’methane slip’.

This unburned methane not fully combusted in an engine can escape into the atmosphere and has the potential to cause tremendous harm. Methane is by some estimates 25 times more potent than CO2 at trapping heat in the atmosphere.

Once abatement methods are validated, MAMII partners will suggest shipping companies adopt these methods. 

Everimpact provides greenhouse gas monitoring technologies for cities using satellites, sensors and AI. In the maritime space, the company has partnered with Mitsubishi and Wilhelmsen to launch a sensor-based continuous emissions measurement system (CEMS) for ships.

The company offers a gas analyser and platform measuring greenhouse gas emissions, including methane, from exhaust stacks in real time. 

“We’re excited that our continuous emissions measurement system, already used to measure fuel emissions from the exhaust stacks of ships, is being evaluated to track methane slip. Joining forces with MAMII will get us one step further on our mission to accelerate the decarbonisation of shipping with better data,” said Everimpact chief executive and founder Mathieu Carlier. 

Denmark-headquartered Green Instruments specialises in cutting-edge measurement and analysis technologies for both marine and land-based industries. Its G7000 CEMS monitors SOx and CO2 emissions for scrubbers.  

MAMII partners believe data gathered from this initiative will enable the industry to move beyond reliance on broad estimates and instead gain actual, vessel-specific measurements.

Safetytech Accelerator head of innovation programmes Nadia Echchihab said, “The technology companies involved in this endeavour are confronted with a multitude of challenges, including adapting their technology for the demanding maritime environment and achieving a price point that is viable for shipowners and operators.” 

“MAMII is bridging this gap by fostering collaboration between industry and technology firms, facilitating joint efforts through feasibility studies and pilots that will yield valuable insights and proof points to be shared with other members of the initiative.”
