Google Joins Satellite Mission To Scan Globe for Methane Leaks

A new satellite mission to track planet-warming emissions of methane gas is finally set to launch, now aided with AI technology to help build a global map of oil and gas infrastructure and surveil it for leaks [Editor's note: the link may be paywalled; alternative source]. From a report: The MethaneSAT satellite was announced by the Environmental Defense Fund six years ago as a way to monitor releases of methane, an invisible gas that researchers estimate is responsible for almost a third of the emissions-induced increase in global temperatures since the start of the industrial era. The satellite is now scheduled to blast into space in March aboard a rocket operated by Elon Musk's SpaceX. On Wednesday, Google said it would provide the AI computing capabilities required to crunch vast amounts of data produced by the orbiting methane monitor. MethaneSAT is the latest example of how satellites are used to detect methane emissions from oil and gas facilities, which is more than 80 times more potent than carbon dioxide at trapping heat in the atmosphere over a 20-year timescale. Experts say reducing methane emissions is one of the most powerful short-term actions needed to address global warming. The International Energy Agency this year found the global energy industry was responsible for 135mn tonnes of methane emissions in 2022, only slightly below record high levels of 2019. Existing satellites have detected more than 500 "super-emitting" events in 2022 from oil and gas operations, the IEA said, with a further 100 such events at coal mines, which can release methane during or after operations.
