Brian Ricketts, an analyst at the International Energy Agency, an energy think tank in Paris, says his group expects coal-to-liquids and gas-to-liquids to account for 10% to 15% of world fuel supply by 2050. Even capturing 1% of world oil demand would mean an output of millions of barrels a day--several times Sasol's current global production. Susan Barrows, a chemist and an energy expert at Harrisburg University in Harrisburg, Pa., reckons that given U.S. coal stocks, the country should be able to produce enough oil from coal to replace 30% of its imports...
...course, nothing's ever that simple in the energy business. Sasol's end product is cleaner than the average diesel fuel or gasoline, emitting less sulfur and less nitrogen when it burns, says Barrows. Coal-to-liquid plants can also be used to clean up the mountains of coal left over at old mines. But in terms of carbon emissions, Fischer-Tropsch is dirty. A sliding scale of emissions from fossil fuels, goes: coal, petroleum, methane. Coal emits the most carbon dioxide per unit of energy obtained. The resultant fuel also emits more carbon dioxide when burned...
...energy company like Sasol to thrive using current technology, "public opinion would have to decide carbon emissions are a necessary evil to bring down the cost of fuel in the short term until more sustainable sources of fuel are discovered," says Barrows. Krupp is blunter. "In order for Sasol to have a profitable future, we have to be cynical about the world's ability to save itself," he says. But Sasol is used to these kinds of dilemmas. "There is a tension here," Davies acknowledges. "All development makes pollution. But China and India want what the West has, so they...
...enough that a civilian model appeared soon after. (Arnold Schwarzenegger was among the first to own one, more than a decade before he became governor of California and a champion of emissions standards.) By the mid-1990s, the Hummer's gleaming chrome grille and 14-m.p.g. (17 L/100 km) fuel consumption epitomized American extravagance. General Motors bought the marketing rights in 1999 and rolled out new models--the H2 and H3--in the face of predictable outrage from environmentalists: one zealot set fire to a Hummer dealership in West Covina, Calif...
...want to give a shout-out to all my Saudi Arabian brothers and sisters. If you could all please send me some oil for my jet, I would truly appreciate it.' SEAN (DIDDY) COMBS, hip-hop mogul, in a video blog, on the high cost of fuel. Combs added, "I can't believe I'm flying commercial...
