The project would collect emissions from industrial facilities along the Houston Ship Channel and bury them beneath the Gulf of Mexico. (Bloomberg) -- Exxon Mobil Corp. proposed a giant, $100 billion hub to capture carbon dioxide emissions along the U.S. Gulf Coast in Texas but warned that government funding would be required to pay for and develop it. In what would be the world’s biggest carbon carbon and sequestration project, Exxon along with a multitude of private and public partners would build a facility to collect emissions from refineries, petrochemical plants and other industrial facilities along the Houston Ship Channel, Joe Blommaert, president of Exxon’s new low-carbon business said in a blog post.
