Engine makers continue to ramp up investment into methane slip reduction solutions for marine engines fuelled with natural gas as regulators finalise emissions targets, including methane slip into shipping’s emissions calculations.

MAN Energy Solutions announced on Monday it is launching the IMOKAT II project to develop an after-treatment technology to reduce methane slip from its four-stroke engines.

Methane slip is the bane of the LNG-fuelled shipping world, particularly now that it is included in lifecycle assessments of fuels calculations for the Fuel EU Maritime regulations and the draft work at the International Maritime Organization.
