Unlocking Solutions: How Feasibility Studies in ID Technology Tackle Fugitive Methane Emissions

Safetytech Accelerate, an industry collaborative, has shared encouraging news about new studies aimed at reducing methane emissions in maritime operations. Following promising results, they are moving ahead to test these findings on ships soon.

Fugitive emissions are a concern along the LNG supply chain, from loading to engine use. Although they are short-lived, these emissions contribute to harmful methane escaping into the atmosphere, adding to the known issue of methane slip — unburnt methane that ends up in exhaust fumes.

Launched in September 2022, the Methane Abatement Maritime Innovation Initiative (MAMII) is spearheaded by the Safetytech Accelerator. This initiative unites industry leaders, tech innovators, and maritime experts to find ways to track and reduce methane emissions at sea. Key players like Chevron, Carnival Corporation, Shell, and Seapeak have collaborated with three technology providers in this effort.

The goal is clear: identify and reduce fugitive emissions to help the industry meet its decarbonization targets.

The feasibility studies focused on three innovative technologies. First, Xplorobot developed handheld devices and an AI platform to detect methane. Their study looked at the gas fuel line’s warm side, and the next step is to test their technology in real-world settings.

Next, Sorama utilized acoustic cameras to monitor LNG carriers. These cameras, placed strategically onboard, visualize sound and vibration to locate emissions. A six-month pilot demonstrated their ability to quickly identify emission sources, suggesting a cost-effective solution for ship operators.

Lastly, Framergy explored a method for capturing and purifying methane during both planned and accidental venting. Their technology uses a special filtering membrane to capture methane at lower pressure, making it possible to reuse or sell the gas.

The findings from these studies point to new ways to detect and reduce methane emissions from LNG-powered ships. Although methane slip is still a significant issue, these advances complement ongoing efforts to tackle emissions from engine exhausts.

Over 20 prominent shipping and energy companies are Anchor Partners in the MAMII initiative. Alongside the four main companies in the recent studies, others involved include MSC, Lloyd’s Register, GTT, NYK, Mitsui O.S.K., CMA CGM, and more.
