Whatcha Gonna Do When C2 Says Goodbye - Could U.S. Ethane Survive Without China?

It looks like the U.S. ethane market may have just dodged a bullet. Since late May, the U.S. Bureau of Industry and Security effectively banned ethane exports to China, the destination for two-thirds of the ethane sent out of Gulf Coast docks — about 225 Mb/d in 2024. Ethane has become a bargaining chip in U.S.-China negotiations over rare earths and tariffs, in part because China has no alternative source of waterborne ethane feedstock for its petchems. But playing the ethane card presented a potential problem for the U.S. too. While China isn’t the only export market for U.S. ethane, there are very limited other destinations for the volumes they typically take. The need to find a home for those volumes could have required significantly more “rejection” of ethane into natural gas at U.S. gas processing plants — i.e., selling ethane for its fuel value instead of recovering it for petchems or export.  In today’s RBN blog, we examine the ethane export issue, which remains in flux as part of the broader U.S.-China trade agreement still being finalized.
