Pickens Plan, the Sequel

Alternative Energy

How can you not love T. Boone Pickens? Here’s someone who made his fortune in oil, and now he’s advising us to switch major parts of the US economy to wind and natural gas. And unlike some of the other concepts for taking a big bite out of our oil consumption, his current idea actually stands a chance of making a significant difference on a timescale of years, rather than decades. At the same time, however, Mr. Pickens has sometimes been a tad bit less than accurate with the numbers he uses to make his points. Remember those ads about the $700 billion per year we were sending overseas to buy oil? Even at its absolute peak in July 2008, reality was more like $500 billion, and the total for 2008 ended up around $385 billion, based on net imports and the average refiner acquisition cost for the year. That’s hardly peanuts, but it’s roughly half his cited figure. So let’s take a look at the key numbers behind his proposal to convert long-distance trucking to natural gas. It’s a great idea, though not quite as much of an economic slam-dunk as it might seem when he describes it.

I just finished reading the interview with Mr. Pickens in The American Spectator, published yesterday. The big shift in the Pickens Plan since the first time I examined it in detail is that he has switched his emphasis from using wind to free up natural gas to replace gasoline in cars, to using the abundant natural gas from our enormous shale gas reserves, which are already transforming the US gas and power markets, to replace diesel fuel in big-rig trucks. He is also in the process of lining up the legislative support to nudge this along much faster than market forces alone would. But does it make as much sense as he suggests when he talks about using $4.50 worth of natural gas to replace 7 gallons of diesel fuel at $3 per gallon?

Strictly in energy terms, that 7 gallons might even be a bit low. A million BTUs of gas (roughly 1,000 cubic feet or one MCF) would deliver as much energy to a truck as 7.8 gallons of diesel. And fundamentally, he’s right that the recent price relationship between natural gas and crude oil makes gas a tremendous bargain, BTU for BTU. However, the prices he mentions in the Spectator interview constitute an apples vs. oranges comparison from both sides. Even if natural gas remained at a steady $4.50/MCF at the wellhead for the next 20 years, which seems unlikely despite the bounties of shale, that’s not what you’d pay at the natural gas pump.

Start with the fact that it costs something to transport gas from the wellhead, wherever that might be, to market. Based on current pricing relationships, if gas starts out at $4.50, then by the time it’s sold to a commercial account, which is probably how filling stations would be classified, it could cost as much as $9. And someone has to invest in the equipment to compress it to 3,000 or 3,600 psi and pump it into an 18-wheeler’s tanks. Even with tax credits to help, a station owner will need to make a return on that investment, and some profit, too. Add another buck an MCF to cover that, and we’re up to $10/MCF, which equates to $1.28/gal. of diesel. For a reality check on this, I took a look at cngprices.com, which shows the locations and pricing for stations selling compressed natural gas (CNG) for vehicles around the country, expressed in dollars per gasoline-equivalent-gallon (GGE). Prices range from roughly $1.25 to around $2, with a few outliers over $3. Since a GGE contains about 10% less energy than a gallon of diesel, you’d have to bump these prices up by about 10% to get the equivalent for a fair comparison.

Under $2 is still pretty cheap, but you shouldn’t compare that to the $2.90/gal average retail price of diesel this week. The latter includes federal excise tax of $0.244/gal. and state excise and sales taxes that range from $0.08-0.49/gal. and average $0.281/gal. As best I can tell, CNG is taxed at the federal gasoline rate of $0.183/gal., while states seem to tax it to a much lesser extent than gasoline and diesel, as for example the $0.085/gal rate in Utah, compared to their state fuels tax of $0.245/gal. However, this is only viable as long as demand for CNG is tiny, relative to other fuels. If Mr. Pickens succeeds in displacing large quantities of diesel with CNG, then it will either need to carry a similar tax burden, or the lost revenues must be collected in some other fashion. If you strip out the taxes to get to an apples-to-apples price to compare diesel to CNG, it works out to around $2.50, give or take a dime or two, depending on location. So while CNG is still clearly cheaper than diesel, it’s rarely $1/gal. cheaper on a truly comparable basis. This, together with conversion costs as high as the $65,000 per truck that Mr. Pickens cited, might explain why market forces alone haven’t led to a rapid switch to CNG-fueled transport.

I’ve looked at the House bill containing the natural gas vehicle tax credits mentioned in the interview. It would cover as much as 80% of the incremental cost (over the diesel version) of a truck that can only burn CNG or LNG, up to $80,000, depending on weight. It would also extend the $0.50/GGE tax credit for CNG and LNG through 2027. These changes would drastically shorten the payout of an investment in a natural gas-powered truck, even if the per-gallon advantage of CNG appears to be somewhat less than Mr. Pickens suggests. That could move CNG into the truck-fuel market pretty quickly.

The remaining question is what the $7 billion investment Mr. Pickens wants the government to make in this proposition would buy us. He believes that converting the US heavy truck fleet to CNG would save 2.5 million bbl/day of diesel, or about two-thirds of the diesel and heating oil now sold in the US. That would have a much bigger impact on our oil imports than ethanol, although it’s hardly an either/or proposition. I’m surprised that Mr. Pickens didn’t go on to suggest that this benefit could be leveraged further by utilizing the resulting surplus diesel in diesel automobiles. Given their approximately 30% improvement in fuel economy vs. comparable gasoline vehicles, that could save 750,000 bbl/day of gasoline, while reducing greenhouse gas emissions on those cars by about 20%. If you play all this out, then just under 5 trillion cubic feet per year of natural gas, or less than a quarter of current gas production, could save more than 3 million bbl/day of gasoline and diesel, or nearly a third of our net petroleum imports.

That sounds like a pretty good deal for $7 billion, though it could be made even better if the vehicle tax credits involved were converted into low-interest loans and loan guarantees, instead. If the main impediment to switching to gas is the up-front cost of natural gas conversions and the time involved in recouping that cost, then let’s make it much easier for truckers to borrow the money for this purpose, and for banks to lend to them. Giving everyone taxpayer money to induce them to do what we want makes a lot more sense when the government has plenty of money to spend. With the US running large deficits and the private sector holding lots of cash earning next to nothing, we should use our tax dollars as efficiently as possible to achieve the same outcome. Otherwise, Mr. Pickens seems to be on to a sensible idea, and I wish him luck selling it.

    The more we diversify our transportation fuels the better. Consumers need choice at the fueling station. Gas, ethanol, diesel, biodiesel, electric charging stations, CNG can all play a role in securing our energy security and economic security.

    It is time to end the OIL monopoly for transportation fuel.

    I can very easily not love T. Boone Pickens due to his funding of the “SwiftBoat Veterans for Truth” who did just enough damage with their lies to give the world 4 more years of George Bush, the science denier. We don’t know what kind of administration Kerry might have had but it could not have been worse than George’s and perhaps steps might have been taken to avoid the recent economic meltdown and address Climate Change and Peak Oil while there was still time and while the nation still had the wealth. Pickens should be cursed everywhere he appears not lauded as some kind of visionary. The only think Pickens cares about is Pickens bank account.

    peak natural gas, huge environmental damage from non-conventional gas, massive use of water, toxics, short time before peak production, diminishing energy profit ratios…all leading to, as noted at the top, peak natural gas in north America even with this non-conventional toxic mess…which will peak not long after the date of peak oil (whatever that was or will be)…does that sound smart?

    Massive conservation and efficiency and transit improvement and solar and wind with storage for them and smart grid and other renewables and THEN and only then, use NG and small amounts of oil where absolutely impossible to find substitutes (and again, after conservation first) is perhaps a sane use of NG…not pie in the sky get-Boone-rich-quick schemes.

    He also supported a war criminal of historic proportions? his crimes in greedy (even if self-delusion telling himself he thinks he is ‘helping’ others) get-Boone-rich-quick schemes is bad enough
