Short summary
This research presents an assessment of fugitive methane emissions from a liquefied natural gas (LNG) power plant in Seoul, using a mobile greenhouse gas (GHG) measurement platform. Three key emission hotspots were identified, including continuous methane leaks and one stochastic super-emitter from the LNG power plant facilities. Our measurements revealed significant discrepancies compared to bottom-up inventories, which fail to capture these intermittent, high-emission events.
