US Gas-to-Liquid Plant Planned By SASOL May Cost $10 Billion  

The WSJ reports that South African coal to liquids company SASOL is looking to build a GTL (gas to liquids) plant in Louisiana, using the (at least currently) cheap supply of shale gas as feedstock - Gas-to-Liquid Site May Hit $10 Billion.

Sasol Ltd., a chemical company long known for squeezing motor fuel out of coal, is now turning its sights on the glut of natural gas in the U.S.

South Africa-based Sasol on Tuesday announced plans to build a plant in Louisiana, at a cost of up to $10 billion, that would convert natural gas into diesel fuel for trucks and other vehicles.

The company's board last week approved an 18-month feasibility study for the project, which would be constructed on land adjacent to Sasol's existing chemical facility in Calcasieu Parish, La.

If given the final go-ahead, the plant would be the first in the U.S. to use "gas-to-liquids" technology. Once seen as futuristic, the technology has gained traction in recent years as discovery of gas supplies have outpaced that of oil.

"The initial numbers look positive," said Ernst Oberholster, Sasol's managing director of new-business development, who stood alongside Louisiana Gov. Bobby Jindal at the company's Louisiana complex when the decision was announced.

What makes the U.S. an attractive location for such a project is the low level of natural-gas prices in the country. Benchmark futures have hovered between $3 and $6 per million British thermal units for two years, well below prices paid by consumers in Europe and Asia.

Sasol would buy the natural gas from suppliers using long-term contracts, convert the gas to liquid fuel and then sell that fuel to blenders, who wouldthen sell it for the open market.

The project is the latest to address what to do with a surplus of natural gas caused by the boom in drilling in shale-rock formations in places like Texas and Pennsylvania. Energy investor T. Boone Pickens and natural-gas producers such as Apache Corp. have promoted the use of natural gas as a road-transportation fuel, one that would be cleaner burning than oil-based alternatives. In addition, some companies have put forward plans to export gas out of the U.S. in cool-liquefied form.

Sasol's idea is one of the most ambitious, because it would essentially put natural gas on par with higher-priced crude oil as a key raw material for transportation fuels. And diesel prices trickle down into the cost of consumer goodseverywhere because the fuel is mainly used in trucking. So far this year, retail diesel prices in the U.S. are up 16%, even as the economy grows more fragile.

Sasol officials estimate that a plant producing 96,000 barrels a day of diesel, and some jet fuel, would cost $10 billion to construct. They say they could opt for a smaller facility, however.

By converting natural gas into a liquid, the fuel could be used without retrofitting vehicles or creating new fueling infrastructure, an issue that would affect motorists using compressed natural gas as Apache and Mr. Pickens have advocated. The proposed site in Louisiana is close to Gulf Coast natural-gas fields and is crisscrossed by pipelines that could be easily linked to a new facility, Mr. Oberholster said.
