Navy’s Big Biofuel Bet:
450,000 Gallons at 4 Times the Price of Oil
Noah Shachtman / DangerRoom, Wired Magazine
(December 5, 2011) — The Navy just signed deals to buy 450,000 gallons of biofuels — arguably the biggest purchase of its kind in US government history. The purchase is a significant step for Navy Secretary Ray Mabus’ plans to transform the service into an energy-efficient fleet. But at approximately $15 per gallon — nearly four times the price of traditional fuel — the new fuels won’t come cheap.
The $12-million purchase, expected for months, will all be used this summer off the coast of Hawaii. There, supersonic F/A-18 jets will launch from the deck of an aircraft carrier, powered by fuels fermented from algae. A 9,000-ton destroyer and a cruiser will join it on a voyage across the Pacific, using fuel made from fats and greases. (The carrier itself runs on nuclear power.) It’ll be the first demonstration of the so-called “Great Green Fleet” — an entire aircraft-carrier strike group relying on alternative energy sources.
If it works, the Green Fleet will not only be poised for a full alt-fuel deployment in 2016. Mabus will be much closer to his promise of obtaining half of the Navy’s fuel from alternative sources by 2020. And the often-struggling biofuels industry will be a lot closer to proving its viability.
“It’s a way to show that this is not a fad, this is not a flavor of the day,” Mabus tells Danger Room. “This is serious. This is real. This is actually going to happen.”
This is hardly the Navy’s — or the military’s — lone effort to find new fuel sources. A Marine company in Afghanistan cut its fuel consumption by up to 90 percent, thanks to portable solar panels and other alt-energy gear. The Navy recently commissioned its first hybrid ship, the amphibious assault ship U.S.S Makin Island. The service is now working to retrofit its destroyers with hybrid drives and mission-planning software that should allow the ships to sail more efficiently.
But biofuels in general — and the Green Fleet demo in particular — are considered tent poles in Mabus’ broader energy strategy. That’s why the Obama administration recently announced that the Navy, along the Departments of Agriculture and Energy, will spend as much as $510 million to develop the country’s biofuel production infrastructure, and to buy up more gas.
Two companies will split the Navy order. Dynamic Fuels, half-owned by agribusiness giant Tyson Foods, converts fats and waste greases into biofuels. Solazyme uses algae as a means of fermenting everything from plant matter to municipal waste into fuel. Both are considered leaders in the next-gen biofuel industry — Dynamic is one of the first companies in the field to have a commercial-scale refinery up-and-running. Solazyme has already delivered 150,000 gallons of its fuels to the Navy.
Substantial hurdles remain, however. The Navy previously paid about $1,000 for each barrel of biofuel it bought to test out in its jets. This new purchase, at first, will cost just as much: $26 per gallon, or $1,092 per barrel. That biofuel will then be blended with an equal amount of fossil fuel, producing 900,000 gallons — and an effective price of about $15 per gallon for that 50/50 blend. It’s “roughly half of what was paid in 2009,” according to Deputy Assistant Secretary of the Navy Tom Hicks, who serves as Mabus’ point man on energy issues.
But it is still far more than the Navy currently pays for its JP-5 jet fuel: $3.97 per gallon, or $167 per barrel.
Mabus notes that this 450,000-gallon buy — while comparatively large for military biofuels — is still tiny compared to the amount of fuel the Navy and the commercial airline industries consume. He’s promised that as the Navy buys more fuel, economies of scale will kick in, and prices will drop.
But an MIT study of alternative jet fuels, conducted in association with the Navy, found that even under optimal conditions — with dozens of refineries up and running — the price of bio jet fuel would still be twice as high as the cost of the traditionally made stuff. (That study examined vegetable oil as a biofuel feedstock, and the Navy is a using different process this time around; but many of the same issues still apply, regardless.)
Clearly, the Navy wants to go green, and reap some of the benefits of having a diversified fuel supply. Whether it can afford to do so — well, that’s still an unanswered question.
Greened for Takeoff

(December 4, 2011) — I’m standing on the concourse watching an Alaska Airlines 737 jet landing in poor weather at Washington DC’s Reagan National Airport. Flight four from Seattle is “greener” than others that touch down here. It’s engines are powered, in part, by a sustainable biofuel. Twenty percent is used cooking oil, 80 percent traditional aviation fuel.
Alaska’s CEO Bill Ayer, says: “The engine operates exactly the same. All of the parameters, everything that we measure technically about engine performance is identical.” Alaska Airlines says if all its aircraft were powered this way for one year it’d be like taking 64,000 cars off the road. Other carriers are testing green fuels too.
Earlier this month, United Airlines flew the first US commercial flight from Houston to Chicago on a biofuel made from algae. In June, the giant US plane maker Boeing flew a commercial jet plane across the Atlantic using a plant-based biofuel.
So, airlines are giving green fuel a go but it can be expensive: The biofuel made from used cooking oil costs Alaska Airlines six times more than normal jet fuel. After three weeks flight four will go back to using regular aviation fuel and a company spokesperson says there are no immediate plans to try again.
Meanwhile, the European Union is forcing Europe’s airlines to go green. There’s no such mandate in the US — though obviously airlines wishing to fly to Europe will have to fall in line.
In the US, the military has taken a lead in pushing for greener aviation, but high costs and insufficient supplies are a drag.
Joanne Ivancic advocates for biofuel technology through her website Advanced Biofuels USA. “First we need to bring down the cost of the technology and the feed stock so that these airlines can afford to buy this fuel. The second thing is we need the policy to say this is really important.”
Aviation analysts like Washington DC-based Peter Goelz say a perception among many Americans that global warming isn’t real also holds back green aviation development.
“The global warming deniers, of which there are a significant portion particularly in the Republican party, are going to have to accept the fact that the rest of the world already accepts that global warming is occurring and that we can do something about it.”
Were that to change, he says, significant investment in green aviation from the US government would most likely follow — even in these dark economic times.
Until then initiatives like Alaska’s are likely to generate good publicity, but make only a fraction of a difference to the environment.
