Pickens to Obama: Oil Era Is Over
Dave Hendricks / infoZine
WASHINGTON, DC (December 04, 2008) — Scripps Howard Foundation Wire — infoZine — And while he’s at it, Obama should offer $50,000 to anyone who modifies his or her 18-wheeler to run on natural gas instead of diesel, Pickens said. Speaking just blocks from the White House at an event sponsored by Republican speechwriters, Pickens pitched his now-famous plan to end America’s reliance on imported oil.
“This is our last chance to get this problem straightened out,” Pickens said. In 10 years, he warned, the US will import 75 percent of its oil — 9 percent more than it did in 2007, according to the government’s oil wonks at the Energy Information Administration. And that oil will cost at least $250 a barrel, he said, more than five times what a barrel of crude oil cost in late November.
By his estimates, the country will shell out $10 trillion for foreign oil over the next decade if imports continue rising. Pickens calls this the greatest transfer of wealth in human history, a river of money he says only natural gas can stop.
Pickens, who made his fortune in oil during the 1980s, now runs BP Capital Management, a hedge fund savaged by the recession. One path to recovery, for both the economy and Pickens’ investments, is his plan to build huge wind farms to free up natural gas for cars.
Wind farms across the Midwest could supply 20 percent of the country’s electricity, replacing the chunk now generated with natural gas. That gas could power cars, an idea Pickens has pitched in numerous TV commercials.
Building thousands of wind turbines across the Midwest would create jobs and shore up Pickens’ hefty investment in wind power. His company, Mesa Power, plans to build the world’s largest wind farm in Pampa, Texas, once the credit crisis clears up. Unable to secure financing, Pickens was forced to delay the project last month.
Pickens met with Obama and Republican candidate Sen. John McCain, R-Ariz., before the election but did not endorse either one.
“President-elect Obama, I think, understands this issue pretty well,” Pickens said.
Despite falling oil prices and uncertainty about the future of wind power, Pickens emphasized that oil is the past, not the future.
“Don’t look for cheap oil,” Pickens said. “That’s over with, it’s done.”

The Abundant Fossil Fuel You’ve Never Heard Of
Jeremy Kutner / The Christian Science Monitor
(December 3, 2008) —At the edges of the Alaskan permafrost, a consortium of government and oil industry scientists are preparing to drill. They aim to tap one of the largest potential energy sources ever discovered, and one that few people have ever heard of: flammable ice crystals packed with hydrocarbons, called methane gas hydrates.
The project, a joint effort between BP, the United States Geological Survey (USGS), and the Department of Energy is set to begin in late 2009 or 2010 and marks the first large-scale production test of this unconventional substance. The group is nearing agreement on a drill site.
Hydrates have been hailed as a paradigm shift in how to achieve energy independence and as a massively abundant source of cleaner-burning natural gas. Others fear it represents an environmental disaster in the making. Until recently it was thought too dangerous and too costly to extract to be of use.
That view is beginning to change. In a recently released report, the USGS for the first time announced details of large hydrate reserves in the Alaskan permafrost that should be recoverable using existing technology. The vast field could hold as much as 85 trillion cubic feet of gas – an amount far less than the dream scenarios put forward in the past, but still massive. Even more important, such movement makes the possibility of getting at the mother lode of hydrate resources – those located offshore – increasingly realistic.
“I never thought this would happen so quickly,” says Carolyn Ruppel, a USGS research geophysicist who was heavily involved in prior hydrate research expeditions, referring to the planned production test. While the number of proposed drilling programs is small and significant obstacles remain, “there has been a real change these past four years,” Dr. Ruppel says. “It’s partially from market pressures.”
Underlying the interest in hydrates is their astonishing abundance – and the fact that they exist domestically in Alaska and the Gulf of Mexico. Their appeal is even greater for countries like Japan and India, which have strained oil or gas reserves but abundant hydrate deposits offshore.
A survey of hydrate estimates published in 2007 put US reserves at around 5,700 trillion cubic feet: “Even this later figure … is [about] 150 times the 95-percent-_confidence-level estimate of US conventional natural gas reserve,” survey author Ruppel wrote, “and [about] 900 times the current annual gas consumption in the US.”
Major hydrate research programs have cropped up in resource-constrained countries like South Korea, India, China, and – most notably – Japan, where Edie Allison of the Department of Energy estimates the government has sunk about $200 million into hydrate research.
In 2007, Japan partnered with Canada to conduct a six-day production test in the permafrost to gain technical knowledge that could help fuel efforts to tap Japan’s vast undersea hydrate resources, perhaps the only major hydrocarbon reservoir that country has left.
The results were encouraging, but still an order of magnitude away from justifying large-scale commercial exploitation, says Gordon Pospisil, technology and resource manager for BP Exploration (Alaska) Inc., which is leading the 2009 Alaskan production test. Production would need to be “about a thousand times higher for this to be clearly economical.”
Malcolm Lall, coordinator of the Indian National Hydrate Pro_gram, says hydrate re__sources off the Indian coast are too large to ignore. Hydrate potential there “is sufficient for the energy needs of India for the next 15 years,” he says. “We’re taking this very seriously.” More energy in__de__pendence is a huge in___centive, he says, and India hopes to do production tests as early as 2013. “The government has given this a lot of priority … [to] get hydrates commercially viable,” he says. “Let’s see who gets it first.”
International and industry researchers will watch the progress of the BP/USGS test. It may, if things go well, turn gas hydrates from curiosity to solid energy policy. Because of the hydrates’ out-of-the-way locations, attractive production rates are necessary for industry and government to consider the vast, costly infrastructure of pipelines and cooling stations needed to get the stuff to market. “The general consensus is that you can expect production problems similar to those of conventional resources,” says Tim Collett, USGS’s lead hydrate research geologist.
Safety concerns also remain. Drilling turns solid hydrates into gas, but this process actually cools the gas, threatening to turn newly liberated gas bubbles back into solid hydrates in the middle of the drill itself – a dangerous prospect. Many also worry that drilling into hydrates might release clouds of gas that could start an underwater landslide. But most experts say that as knowledge of methane hydrates improves, drilling sites are moving away from high-risk areas.
Whether hydrates represent a key to domestic energy independence or an unnecessary risk is unclear. Hydrates represent a dramatic addition to natural gas resources, but natural gas, despite being cleaner than coal or oil, is still a fossil fuel that produces greenhouse gases. And raw methane, should it escape into the air, is more than 20 times as potent a greenhouse gas as CO2.
“If you still want to produce CO2, natural gas is much better than coal, but as a geoscientist I just get angry that you ever have to burn methane or coal,” says Keith Kvenvolden, formerly of the USGS who has been studying hydrates for more than 30 years.
What are methane gas hydrates?
Trapped in ice crystals beneath the arctic permafrost and deep below the ocean is a volatile store of energy so vast that it could redefine world politics.
The mystery substance is methane gas hydrates, solid blocks of ice stuffed with methane gas molecules – natural gas. They are found all over the globe in such astoundingly large amounts that early estimates stated that there were more hydrates than all other fossil fuels combined. Better-informed estimates have tamped down those early figures, but hydrate reserves are still thought to be enormous.
Hydrates, which look like chunks of ice, were first brought to world attention in the mid-1960s by Russian scientists. Hydrates are compounds of water molecules that form under pressure and at low temperatures. They are like ice “cages” that trap gas molecules inside as they freeze.
Hydrate water molecules are very accommodating: An ice cage consisting of a single molecule of frozen water can theoretically hold 160 gas molecules – meaning that finding just a small amount of hydrate can mean a lot of harvestable gas. And while hydrates can suck up a wide range of gases, the most common one is methane, clean-burning natural gas. Hydrates look like chunks of ice. You can even hold them in your hand – or light them on fire.
When the Soviets failed to find a way to exploit them, hydrates became little more than an academic curiosity for three decades. Barriers to exploration were large. The most abundant hydrates were thought to exist only in places forbidding to commercial exploration: in the arctic permafrost and scattered along continental margins under the sea.
No one knew how best to find them.
Rising oil prices, energy-security concerns, and better science has renewed interest in hydrates, which, it turns out, can be harvested much the way natural gas is, even though hydrates are solid.
