Maritime Methane Initiative Wraps Feasibility Studies with Tech Partners

Safetytech Accelerator, in collaboration with Capital Gas Ship Management, MSC, and Seapeak, has completed four technology feasibility studies as part of its flagship Methane Abatement in Maritime Innovation Initiative (MAMII).

Daphne Technology, CDTi Advanced Materials, Inc. (CDTi), Rotoboost, and Plenesys were selected by MAMII from amongst 20 companies to help address the critical challenge of mitigating methane emissions from the exhaust stacks of LNG fuelled ships.

The outcomes of these feasibility studies showed strong potential to cut methane emissions in the maritime industry.

Daphne Technology’s methane abatement system outlined a potential reduction of up to 440 metric tons of methane annually in container ships.
CDTI’s results highlighted how a proven engine catalyst could offer increased methane conversion at lower temperatures than industry norms, with minimal operational adjustments for fleets.

Plenesys demonstrated a solution which can effectively reduce methane slip by 78% by converting it to hydrogen, while Rotoboost’s system was found to offer several benefits including additional revenue from carbon by-products.

MAMII hopes to progress these research projects to on-ship trials as soon as possible. MAMII was launched in September 2022 by Safetytech Accelerator, bringing together industry leaders, technology innovators, and maritime stakeholders to advance technologies for measuring and mitigating methane emissions in the maritime sector and promote the adoption of validated solutions.

It currently has 20 leading shipping and energy companies as Anchor Partners.

Each provider selected for trials brings expertise in a different technology:

Daphne Technology’s SlipPureTMis a plasma-catalysis -based methane abatement solution installed in exhaust stacks. The system converts methane into carbon dioxide and water.
CDTi uses emissions catalysts to passively oxidize methane in the exhaust stream and reduce its release into the atmosphere.

Rotoboost enables on-site low-carbon hydrogen production through thermo-catalytic decomposition (TCD) as pre-combustion Carbon Removal & Methane Slip Reduction solution. In Maritime, Oil & Gas applications, hydrogen can be blended as a drop-in fuel with LNG.

Chris McDade, Vice President, Operations at Seapeak said: “Seapeak are always looking for opportunities to drive change in the maritime industry, especially in relation to our environmental responsibilities.

Alexandra Xystra, Technical Manager, Capital Gas Ship Management, said: “As part of our strategic initiative to lead in sustainable maritime operations, Capital Gas Ship Management is committed to exploring and implementing advanced methane abatement technologies.

Kaisa Nikulainen, CEO at Rotoboost said: “The collaboration has been exceptional, bringing together charters, ship owners, LR, and industry partners such engine/equipment makers, to expedite the decarbonization process and reduces the carbon footprint of the assets”.

Nadia Echchihab, Head of Innovation programmes, Safetytech Accelerator, said: “We are delighted to join forces with our valued partners, MSC, Seapeak, and Capital Gas, in introducing these innovative methane abatement solutions through the MAMII initiative. These technologies represent a significant stride towards mitigating methane emissions in the maritime industry, contributing to a sustainable and cleaner future for our oceans and the planet”.
