Maran Gas, Daphne Technology conclude methane abatement pilot on LNG carrier

Swiss-based climate tech company Daphne Technology and Greek shipping player Maran Gas, part of the Angelicoussis Group, have completed their joint methane abatement pilot onboard commercial LNG carrier.

First announced in 2023, the project involved the first deployment of Daphne Technology’s SlipPure plasma-catalytic methane slip aftertreatment system onboard Maran Gas Chios.

The pilot aimed to address methane slip challenge in LNG-fueled vessels. Methane slip refers to the unintentional release of unburned methane, a potent greenhouse gas, into the atmosphere during the combustion process in LNG-fueled engines.

Designed to abate methane directly from exhaust gases, Daphne Technology’s DNV-approved system was retrofitted on the vessel to test the feasibility of this approach under real operating conditions.

As reported, Daphne Technology achieved reductions of up to 4 ± 2 g/kWh methane slip during the trial, demonstrating that plasma-catalytic-based abatement is possible onboard an LNG carrier. These results represent a first step in validating the technology at sea and provide critical insights for the next phase of development.

The initiative also demonstrated the Angelicoussis Group as an early
