Under　the　context　of　carbon　neutrality　of　China,　it　is　urgent　to　shift　our　energy　supply　towards　cleaner　fuels　as　well　as　to　reduce　the　greenhouse　gas　emission.　Currently,　coal　is　the　main　fossil　fuel　energy　source　of　China.　The　country　is　striving　hard　to　replace　it　with　methane,　a　cleaner　fossil　fuel.　Although　China　has　rich　geological　resources　of　methane　as　coal　bed　methane　(CBM)　reserves,　it　is　quite　challenging　to　utilize　them　due　to　low　concentration.　The　CBM　is　however　mainly　emitted　directly　to　atmosphere　during　coal　mining,　causing　waste　of　the　resource　and　huge　contribution　to　greenhouse　effect.　The　recent　work　by　Yang　et　al.　demonstrated　a　potential　solution　to　extract　low　concentration　methane　selectively　from　CBM　through　using　MOF　materials　as　sorbents.　Such　kind　of　materials　and　associated　separation　technology　are　promising　to　reduce　greenhouse　gas　emission　and　promote　the　methane　production　capability,　which　would　contribute　to　carbon　neutrality　in　dual　pathways.　(c)　2022　Institute　of　Process　Engineering,　Chinese　Academy　of　Sciences.　Publishing　services　by　Elsevier　B.V.　on　behalf　of　KeAi　Communications　Co.,　Ltd.　This　is　an　open　access　article　under　the　CC　BY-NC-ND　license　(http://creativecommons.org/licenses/by-nc-nd/4.0/).
