The Environmental Protection Fund (EDF) has partnered with Google for MethaneSAT, a brand new satellite tv for pc that may map, measure, and monitor methane globally.
MethaneSAT will launch in early Could on a SpaceX Falcon 9 rocket, Google mentioned in a information launch. The satellite tv for pc will orbit Earth 15 instances a day at an altitude of over 350 miles. It can measure methane ranges within the high oil and fuel areas on this planet for normal evaluation. The 200-plus kilometer satellite tv for pc view path is massive sufficient not solely to quantify recognized sources, but in addition to find and quantify beforehand unknown sources, EDF mentioned.
MethaneSAT has the power to observe each high-emitting methane sources and small sources unfold over a large space, in accordance with the discharge. It’s designed to measure areas at intervals below seven days, commonly monitoring roughly 50 main areas accounting for greater than 80 % of worldwide oil and fuel manufacturing.

To calculate the quantity of methane emitted in particular locations and monitor these emissions over time, EDF developed algorithms powered by Google Cloud in collaboration with scientists at Harvard College’s Faculty of Engineering and Utilized Science and its Middle for Astrophysics, and scientists on the Smithsonian Astrophysical Observatory.
Google mentioned it’s creating a world map of oil and fuel infrastructure, with the aim of understanding which elements contribute most to emissions. The corporate will use AI to establish oil and fuel infrastructure, like oil storage containers, within the imagery, and mix it with EDF’s details about oil and fuel infrastructure to find the place emissions are coming from.
As soon as the infrastructure map is full, the MethaneSAT information may be overlayed and present the place methane is coming from. “This data is extremely helpful to anticipate and mitigate emissions in oil and fuel infrastructure that’s usually most prone to leaks”, Google mentioned.
As it should deal with methane, MethaneSAT shall be inexpensive and faster to launch than the multi-function satellites constructed by authorities house businesses, EDF famous. MethaneSAT will fill vital information gaps left by different satellite tv for pc techniques which are presently deliberate or just lately deployed, enabling firms and nations to make higher selections and take motion sooner.
To assist researchers and organizations, the insights from the satellite tv for pc shall be accessible later this yr on MethaneSAT’s web site and accessible by Google Earth Engine, a planetary-scale environmental monitoring platform. By making MethaneSAT datasets accessible on Earth Engine, which has over 100,000 month-to-month lively customers, customers will be capable of detect developments and perceive correlations between human actions and environmental influence, Google mentioned. For instance, Earth Engine customers can mix methane information with different datasets resembling land cowl, forests, water, ecosystems, and regional borders to trace methane emissions in a given space over time.
With the vitality transition underway globally, firms have been more and more specializing in utilizing satellite tv for pc information to acquire higher information on emissions. In November 2023, GHGSat Inc. launched the primary orbital sensor capable of pinpoint carbon dioxide emissions from particular person industrial amenities.
The GHGSat C10, also called Vanguard, was efficiently launched by the corporate from Vandenberg House Pressure Base in California. The satellite tv for pc builds on GHGSat’s expertise with methane emissions to supply frequent, correct and impartial high-resolution carbon dioxide information from particular person websites, and “will rework the way in which carbon dioxide emissions are monitored, reported and traded”, the corporate mentioned in an earlier assertion.
The excessive spatial decision of the Vanguard permits it to deal with particular person targets and precisely attribute emissions, one thing that present public carbon dioxide satellites are unable to do, GHGSat mentioned.
