For a number of reasons, all eyes will be on Mariner East 2, which will increase the U.S.’s ability to export ethane and LPG to Europe, as it stumbles toward completion. For U.S.-Europe NGL trade, it comes as Europe’s steam crackers are consuming growing volumes of ethane and LPG. However, the development of Europe’s ethane imports continues to fall short of expectations. Despite the Mariner East expansion, it will be surprising if ethane shipments via Mariner East rise to much more than 80,000 b/d six to 12 months from now. On the other hand, the expanded terminal’s LPG capacity will re-route existing LPG exports and be fully utilized. The most critical and far-reaching market development associated with Mariner East 2, however, is the timing and ramp-up of increased LPG exports. As the Global LPG Balance Chapter describes, demand growth outside North America will hit a wall when a lack of new U.S. terminal capacity chokes foreign access to North America’s growing LPG supply.
