Excerpts from the article:

Dow Chemical Co. (DOW) spent a decade moving chemical production to the Middle East and Asia. Now it’s leading the biggest expansion ever seen back home in the U.S. as shale gas revives the industry’s economics.

Driving this renaissance is the plunge in the price of natural gas, used in crackers as a raw material, to a nine-year low. New drilling methods are opening up vast shale formations from Texas to West Virginia. U.S. chemical investments stemming from shale gas may top $16 billion, creating 17,000 jobs directly and another 400,000 indirectly, according to the American Chemistry Council, a Washington-based industry group.

“The U.S. now has investment-grade economics, and because of shale we are going to lock those economics in,” Dow Chief Executive Officer Andrew Liveris said. “We can grow our Americas base off our U.S. Gulf Coast assets. That is a big change.”

Shale gas has been a “game changer,” Swift said. “The U.S. has emerged as a low-cost producer of many of these products.”
