Buying Your Own Refinery

Has the high cost of fuel got you down? Why not buy your own oil refinery? That's apparently what Delta Air Lines is considering. With jet fuel purchases constituting one of the largest operating costs for carriers like Delta, and with several refineries in the Northeast US facing permanent closure due to poor profitability, it's not hard to see why this idea would seem attractive, at least superficially. However, there are a host of reasons why most of the press I've seen on this story is negative, including today's Heard on the Street column in the Wall St. Journal, entitled, "Delta Chases Fuel's Gold." The fundamental problem is the same one that has made me skeptical about the benefits of airlines investing in the production of renewable aviation fuel: Any advantageous pricing they may choose to provide to their airline division must come at the expense of lost opportunities for the fuels business, because the value of that fuel is set by the market.

How a company should reflect such opportunity costs in its inter-departmental transfer pricing is an age-old problem. I dealt with this routinely when I traded refined products for Texaco's west coast refining and marketing business in the 1980s. The marketing department always wanted to receive the output of the refineries at a lower price than we were charging them, so that they could capture market share and justify investments in new and remodeled gas stations. But making them look good at the cost of the refineries just made it harder to justify the investments needed to keep the refineries operating efficiently and in compliance with current and future regulations. Delta might buy ConocoPhillips' Pennsylvania refinery at a low price today, but they could be forced to invest at least as much within a few years to meet new gasoline sulfur regulations or other changes. It doesn't trivialize the situation to put it into the category of no free lunches.

Then there's the question of reorienting a refinery to make a lot more jet fuel that it has done historically, as one article suggested Delta was considering. Modern refineries are fairly flexible, and it would be possible to do that to some degree, though within limits that would require significant investments to exceed, making the proposition look much less attractive. Moreover, refineries optimize their output every day to make the slate of products that yields the highest profit, as crude and product prices fluctuate. Steering a less flexible course would almost certainly make the facility less, not more profitable, and it's only on the market because it wasn't sufficiently profitable as it was.

The only scenario in which I could see this idea actually working to Delta's benefit is if the refinery closures now being planned tightened the supply of jet fuel into the New York market so significantly that Delta was able to effectively corner that market, forcing other airlines to pay it a significant premium, either in cash or in jet fuel supply in other locations, while artificially keeping costs for its own flight operations low and allowing it to expand its share of the important NY air market. But New York isn't some isolated inland location, and they'd always be competing with jet fuel cargoes brought in by vessel, or with fuel shipped from Gulf Coast refineries via the Colonial Pipeline, which is expanding to meet the new demand its faces in light of the pending refinery closures. They might eke out a few extra cents, but would that be enough to justify taking on the enormous capital and operating costs--not to mention the substantial operating risks--of owning a refinery? If Delta has discovered some enticing angle I've missed, I'd love to know what it is.

Fueling the Aerotropolis

Roger Cohen's column in Monday's New York Times sent my mind spinning with its portrayal of a global network of airport-based businesses and organizations that might have closer links to airports a country or continent away than with the traditional urban centers for which these facilities are often named. I'm embarrassed to admit that it was the first time I had run across the "Aerotropolis" concept, which has apparently been around since 2000. Its implications are thought-provoking, not least for their impact on energy and the environment.

The term aerotropolis was apparently coined by a professor at the University of North Carolina business school; it's also the title and subject of his new book. It evokes a retro-1920s science fiction vision of gleaming cities connected by flying cylinders, crossed with the gritty reality of the modern airport and its environs. I wasn't surprised to learn that a third of world trade-- though just 1% by weight--moves by air, but the idea of a hospital integrated into an airport in Hyderabad, India, or an entire city in South Korea growing up around the Incheon International Airport was new to me. The possibilities seem endless, though I can't think about them without also considering where the energy to facilitate the implied explosion of air travel and air freight will come from.

A few years ago, I would have said that air travel was even more closely linked to petroleum than are automobiles. That's not because alternative aviation fuels seemed impossible--quite the contrary--but because the aviation world has historically been understandably cautious and conservative about what goes into the engines that power aircraft. From a technical standpoint, jet turbines offer a great deal more fuel flexibility than the internal combustion engines under the hoods of most automobiles. However, while a fuel failure in your car is a major inconvenience, a fuel failure at 30,000 feet is catastrophic. In some respects the alacrity with which the aviation industry has begun to embrace alternative fuels is nearly as big a surprise as the shale gas revolution, and perhaps ultimately as transformative. Airlines and militaries have entered partnerships and set targets for integrating alternative jet fuel into their consumption, and supplies are gradually appearing.

Scale remains an issue. Kerosene-based jet fuel accounted for 7% of US petroleum consumption last year, down from nearly 8.5% a decade ago, as air carriers have transitioned to more efficient aircraft and higher load factors. That's still a big volume, though it turns out to be easier to make suitable kerosene substitutes from a variety of sources, including natural gas, coal and biomass, than to make comparable substitutes for gasoline. Nor does jet fuel produced from camelina seeds, algae, or the gasification and FT-synthesis of bulk biomass, natural gas or even animal fat entail the kind of performance penalties inherent in our primary gasoline alternative, ethanol. Delivering on this potential will require significant investment, but of a magnitude that seems much more achievable than what is required for many other renewable energy goals.

Another important aspect of scale concerns the logistics of gathering enough biomass to produce meaningful quantities of "biojet". The government of Ontario Province just awarded Rentech, Inc., a company with long expertise in gasification and fuel synthesis, a 1.3 million ton-per-year supply of forest waste and other biomass from Canada's Crown Forests, specifically for the production of renewable jet fuel. The proposed facility would produce around 22 million gallons per year of biojet, along with another 11 million gallons of non-jet products. That equates to roughly 1% of Canada's current jet fuel consumption. Canada might have enough forest biomass available to produce a sizable fraction of its jet fuel needs from such sources, but other countries don't, so it's fortunate that alternative jet fuel can be made through so many different pathways.

That's also fortunate for the aerotropolis concept, because without an incremental supply of non-petroleum jet fuel, meeting the energy needs inherent in this idea without dramatic increases in aviation's current approximately 3% share of global greenhouse gas emissions could become a major obstacle within just a few years. With sufficient supplies of renewable and gas-to-liquids jet fuel, the concept might even be able to withstand a peak in global oil output, even if the price of such alternatives seems likely to track that of oil-based jet fuel.

How Fast a Transition from Oil?

The Gulf Coast oil spill remains the top energy story this week, eclipsing a $10 drop in oil prices that should soon ripple through to gas pumps near you. With BP's latest effort to contain the spill having run afoul of a slush buildup composed of methane hydrate crystals, the deepwater well continues to leak at an undetermined rate. The longer the spill continues, the greater the chances for severe environmental consequences, and the likelier that it will become a perception-altering milestone event as some environmentalists have already suggested. However, even if the spill were to galvanize public opinion in a manner similar to the 1969 Santa Barbara oil spill, what options do we have that could realistically reduce our reliance on oil produced from offshore platforms?

Last week I focused on the energy contribution of the oil we produce offshore in US waters, particularly in the deep water of the Outer Continental Shelf (OCS) of the Gulf of Mexico. It constitutes 30% of domestic crude oil production, or about 10% of our total oil consumption, and contrary to the wildly-inaccurate assertion on a widely-read environmental blog last week, essentially none of it is exported. (Anyone who doesn't know the difference between crude oil and petroleum products has no business commenting on that aspect of energy policy.) Today I'd like to go into a little more detail on the alternatives to offshore drilling that I alluded to last Wednesday.

Gasoline, jet fuel and diesel accounted for 75% of the petroleum we consumed last year. Other than the heating oil included in the diesel tally, these are the fuels that power most transportation of people and goods. Many initiatives are under way to develop non-petroleum fuels for cars, trucks and even jet aircraft, though at this point they are all in relatively early stages of development or deployment. On paper, at least, electricity looks like the best option for replacing gasoline, by means of plug-in electric vehicles like the Chevrolet Volt and Nissan Leaf. Since less than 1% of US oil consumption is used to generate electricity, switching cars from gasoline to electric power represents a nearly total displacement of oil. It would also facilitate the direct use of renewable electricity sources to eliminate greenhouse gas emissions. This prospect has many people excited, and I've heard it mentioned frequently in reactions to the Gulf spill. Yet this is hardly a slam-dunk, for numerous reasons, topped by scale and the unproven consumer acceptance of mass-market EVs.

In one of their periodic special sections on energy, today's Wall St. Journal included an article on the development of EV recharging networks in the US. It cited a study by Pike Research forecasting 610,000 EVs by 2015. That would be a great start, though it would fall short of President Obama's goal to put a million plug-in vehicles on the road by then. Even assuming that the million-EV mark were reached that soon, and that they were driven as much as other cars and replaced vehicles averaging 25 mpg, the quantity of gasoline they would displace amounts to just 31,000 bbl/day--less than the quantity of oil the leaking Macondo field would have been producing in a couple of years, had Deepwater Horizon's exploration well been completed uneventfully. Substituting for all of the oil currently produced from offshore drilling--or for the decline in US oil production that would occur by 2020 if we stopped drilling offshore--would require up to 50 million EVs, making up roughly 40% of all the cars likely to be sold in the US this decade. I suppose that might barely be possible on a crash basis, with a World War II-style mobilization of the resources required to achieve it, but it doesn't look very likely to me. I would be impressed if the US had 10 million EVs by 2020, implying annual production of well over a million units within just a couple of years, though that would reduce our current oil demand by under 2%.

So if EVs can only take us a small part of the way to replacing our oil consumption in the near future, what about advanced biofuels? There are many promising avenues, including biofuels produced from agricultural or forestry waste or dedicated energy crops, biofuels from algae, and bio-hydrocarbons from plant sugars. All are in their infancy. The EPA recently had to reduce its mandate for advanced biofuels delivered in 2010 from 100 million gallons to just 6.5 million gallons--424 barrels per day--because no truly commercial-scale facilities will come on-stream this year. We might get a few billion gallons per year from these sources by 2020, if numerous technical and economic hurdles can be overcome, but that would displace at most a couple of hundred thousand bbl/day of oil.

Natural gas looks like another good alternative transportation fuel. T. Boone Pickens has put forward his plan to shift long-distance trucking onto compressed or liquefied gas. There's no shortage of gas available for this purpose, thanks to the much larger supplies made possible by shale gas drilling. It starts from a very low level, however, with current natural gas used in transportation equivalent to less than 1,500 bbl/day of diesel fuel. It also competes with other uses of gas, such as generating more electricity to reduce our consumption of coal. Or, looking at it another way, there might be plenty of gas to do both, but not at today's price.

That leaves what looks like the best option for reducing our oil consumption, other than simply deciding to drive less, as some folks have apparently already done. Because the US car fleet is so large and is driven so far, increasing its fuel efficiency by just 3 miles per gallon could save nearly a million bbls/day of gasoline. That's more than the entire contribution of corn ethanol, our most significant alternative transportation fuel. In fact, the latest demand forecasts of the Energy Information Agency are already based on that kind of improvement, reflecting new regulations requiring new-car fuel economy to increase to 35 mpg before 2020. Still, only a small fraction of our fleet of 240 million cars turns over every year, so it will take a long time before average fleet fuel economy even begins to approach these levels.

Whether your preferred alternative to offshore drilling requires replacing millions of vehicles with hybrids, EVs, natural gas-powered vehicles, or highly-efficient small conventional cars like the new Ford Fiesta, or depends on a vast new infrastructure of alternative fuel production and distribution, none of these solutions can work overnight. In the meantime, every barrel of oil we consume but don't produce here must be imported, some of it from countries that don't like us very much--as we're frequently reminded--and all of it with serious implications for our national financial and trade balances. (And don't forget the inevitable oil spills from all those extra tankers.) If we don't want OPEC to be the biggest beneficiary of a new environmental mindset after the Gulf Coast spill, then we face some very tough choices, including whether we'd prefer to open up major new areas for onshore drilling, instead of some of the offshore prospects that were slated to be leased in the next few years, or to continue drilling offshore under updated procedures and with strengthened environmental protections, at the same time we pursue all of our options for reducing our overall reliance on oil.

Understanding Southwest's Hedging

I don't normally pay much attention to the quarterly earnings reports of companies outside the energy sector, so I initially missed the confusion over the impact of fuel hedging on the third quarter results of Southwest Airlines. An article in yesterday's Washington Post brought this to light again, along with the effect of falling oil prices on the fuel hedging efforts of a diverse group of companies, including Coca Cola, Royal Caribbean Cruise Lines, and local heating oil distributors. The reporting on this subject illustrates two important points: commodities hedging is no free lunch, and understanding its full consequences requires more that a superficial look at the bottom line.

This morning I pored over Southwest's quarterly earnings press release to see what had happened. I was suspicious of the headlines suggesting that hedging had pushed Southwest into the red, because the average futures price of West Texas Intermediate crude oil for the quarter was $118 per barrel--hence ExxonMobil's record-breaking earnings--still well above the level at which Southwest was generally understood to have hedged its jet fuel. After some scrutiny, and to my considerable surprise, I concluded that both the Post and the Wall Street Journal in their earlier story on Southwest's earnings appeared to have misinterpreted some key aspects of the hedging results. Discerning that wasn't easy, since Southwest saw fit to report their earnings on both a GAAP (Generally Accepted Accounting Principles) and non-GAAP basis, and the intricacy of their "Reconciliation of Impact from Fuel Contracts" table forced me to jump-start some brain cells that have been dormant since my B-school financial accounting course.

Evaluating the benefit or cost of a hedge must include the result of the physical transactions it was intended to cover. In the case of Southwest, it appears that its unhedged fuel cost for the quarter--what it actually paid its fuel suppliers--was $1.387 billion. The hedges and related derivative contracts that settled in the quarter offset that by $448 million, reducing Southwest's effective fuel bill to $939 million. The problem that the Journal and Post focused on was related to future hedges, not those that unwound between July and September. Marking the company's total hedge portfolio to market resulted in an additional pre-tax cost of $247 million, reported as a special item. Factoring this in turned the company's modest operating profit of $69 million into a $120 million net loss, after tax. But it's not correct to say that hedging hurt Southwest. Had it not hedged at all, its after tax loss for the quarter would have been approximately $189 million, assuming it could have operated in the same manner. That seems unlikely, given the behavior of competitors with less active hedging programs.

But while the confusion over Southwest's earnings seems to arise from the requirement to recognize the reduced value of the future hedges still on its books as a loss to current income, this doesn't justify calls to set aside mark-to-market accounting. That special item should prompt investors to read the explanation Southwest has provided concerning its overall hedge portfolio, because it signals the prospect of further hedge-related losses in the future:

"In addition to our fourth quarter 2008 derivative position, we have derivative contracts for over 75 percent of our estimated 2009 fuel consumption at an average crude-equivalent price of approximately $73 per barrel; approximately 50 percent of our estimated 2010 fuel consumption at an average crude-equivalent price of approximately $90 per barrel; approximately 40 percent of our estimated 2011 fuel consumption at an average crude- equivalent price of approximately $93 per barrel; over 35 percent of our estimated 2012 fuel consumption at an average crude-equivalent price of approximately $90 per barrel; and have begun building a modest position for 2013."

That means that if oil prices remain between $60 and $70/bbl, then the effective cost Southwest will pay for jet fuel in future quarters could end up higher than that of competitors who didn't hedge or who hedged lower percentages of their expected fuel consumption than Southwest. Of course, that's not certain, either, because the price of oil might again rise above the level of their hedges.

The key to a successful hedging strategy is that companies shouldn't view it as a magician's hat out of which to pull larger profits, quarter after quarter. The benefit comes from reducing the volatility of earnings and enabling firms to continue operating more normally, when others have had to cut back drastically. Although this strategy could rebound on Southwest, if oil prices remain low for an extended period, falling prices may not hurt them as much as rising prices have hurt their less-hedged competitors, some of whom are now in a very poor position to capitalize on lower fuel costs.

Note: Energy Outlook will be on vacation next week, with postings resuming the week of November 10.

Airlines vs. Speculators

Yesterday a friend sent me a copy of an email letter she had received from an airline on which she is a frequent flyer. It made an urgent plea for public support to rein in oil market speculation, which it blamed for between $30 and $60 per barrel of the current oil price, which has been ruinous for the airline industry. Millions of Americans received the same letter--apparently I haven't flown enough, lately, to merit one--with a link to the "Stop Speculation Now" campaign website. Congress and the Commodity Futures Trading Commission have been grappling with this issue, and new energy futures market regulations should be forthcoming shortly. However, I hope that the chiefs of America's airlines are not banking on a speedy return to sub-$100 oil, and the $1.00 or more per gallon this would subtract from their jet fuel bills. Even if all speculation were eliminated tomorrow, the combination of a weak supply response and the low price elasticity of demand for oil make it unlikely that prices would quickly revert to last fall's $80-$95 per barrel price range.

For the last year, I have discussed the potential impact of speculation on oil prices. Investment in oil futures, options and derivatives as a new asset class has affected the market in ways that traditional speculation by financial players--a key ingredient of market liquidity--didn't. Even if these investors never take delivery of a single barrel of oil, they constitute a new segment of demand for oil futures and exert upward pressure on the market. I have also described at length the mechanism by which the resulting higher futures prices affect the prices that refineries pay for the physical barrels of oil they process, and why in that margin-based business, resistance to higher prices is likelier to come from end users, rather than refiners. But none of this alters the main facts governing the price of oil: The growth of global demand over the last five years has consumed most of the existing spare production capacity, and restrictions on access to resources--within OPEC and the US--combined with the time-lags inherent in bringing new supplies online have left the market balanced on a knife edge, setting up the conditions without which asset-class investments in oil futures would just be another complicated way to lose money, which may still be the ultimate result for many.

In a recent Wall Street Journal op-ed, Martin Feldstein, a former chairman of the Council of Economic Advisers, provided an exceptionally clear explanation of how small changes in supply and demand can translate into large price movements for commodities with very low short-term price elasticity, or sensitivity, of demand. Yesterday I discussed the recent demand response in the US. It took $4 per gallon pricing to halt the steady year-on-year rise of US gasoline consumption, a trend that was unbroken since 1991. And in the absence of serious refining problems, the only two paths to $4 gasoline were $130 oil or the imposition of a $1.00 per gallon surtax when oil was still under $100/bbl. Constraining the futures market now might provide some temporary relief, but it won't resolve the underlying problems that brought us to this point.

I don't blame the CEOs of the airlines for grasping at this straw. The signatories to the letter include my former boss at Texaco, Glenn Tilton, who understands the oil and airline businesses better than most. These executives know that a commercial aviation industry built on cheap fuel will emerge from a long period of sustained high oil prices as transformed as if it had been re-regulated, and that the mass access to cheap and convenient air travel that we have taken for granted could disappear. Their effort here may even pay off, but as I noted recently, the exact form of any new regulations on energy trading matters greatly, if the cure is not to be worse than the disease.
