Airlines and Jet Fuel Usage

Trying to Lighten That Carbon Footprint

In February, on a chilly, clear Sunday morning, Sir Richard Branson, president of Virgin Atlantic, along with the co-sponsors Boeing and GE Aviation, lured more than 200 journalists to a hangar at Heathrow Airport near London to witness what they said was airline history. Over flutes of Champagne and plates of mini-bagels filled with salmon, everyone’s eyes were fixed on a 747 as it took off on the world’s first biofuel demonstration flight.

Never mind that only one of the plane’s engines used biofuel, and that was about 25 percent mixed with standard kerosene jet fuel. It was still significant, given that air travel is the fastest-growing source of global greenhouse gases, and the race to find an alternative to kerosene is now crucial. The biofuel used — a combination of coconut and babassu (a Brazilian tree) oil, which Mr. Branson pretended to drink that day like an island cocktail from a coconut shell — worked in this very small test. But even its developers, Imperium Renewables, are aware it could never become a substitute for what John Plaza, president and chief executive of Imperium, another sponsor, says is the 87 billion gallons of fuel needed each year to fly the world’s airline fleet.

“This is just a first-generation product,” Mr. Plaza said. “But the test was meaningful in that it showed that a biofuel was viable with the infrastructure in a commercial jet.” Imperium created the fuel from oils harvested from existing plantations, but Mr. Plaza said he believed that algae was the fuel of the future. “You would only need the landmass of West Virginia,” he said, “to make enough fuel to replace aviation’s demand for kerosene.”

Still, the environmental group Friends of the Earth was quick to criticize the Virgin event as a public relations stunt, restating its view that carbon savings from biofuels are negligible, and the now well-publicized position that growing crops for alternative fuels cuts into the land available to grow food. “There is a finite amount of land for food,” said Kate Horner, a climate and energy campaigner for Friends of the Earth, “and using it for the expanded production of fuel is driving deforestation, which accounts for one-fourth to one-third of our global emissions.”


Mr. Plaza said the biofuel industry was receiving too much blame for the food crisis. “There are many factors, like drought, that are causing the problem,” he said. “And for those of us looking for funding to develop future biofuels that do not rely on feed stocks, it makes it very hard given all the negative press.”

Few in the transportation world dispute that solutions must be found. According to the International Civil Aviation Authority, more than 2.2 billion people flew last year, and though commercial flights account for only 2 percent of global greenhouse gas emissions, the International Panel on Climate Change recently stated its concerns that aerosols in jet engine exhaust may be depleting the ozone at two to four times the rate of ground-level carbon dioxide. Add to that Boeing’s prediction that by 2025 the global fleet will have doubled to 36,000 planes, and the need to find answers seems unquestionable.

Many government leaders and environmental groups would prefer to see more regulatory action taken, such as an international pact to stem global aircraft emissions. Last September a petition was filed with the United States Environmental Protection Agency asking it to address the effects of global warming from the world’s aircraft fleet.

  1. so what’s your point? i mean these fuckers are a riot. they’re funny as hell.

    algea? you need water, at a minimum, to grow algea. if you want a lot of algea, you need a lot of water. most usable water is kinda spoken for already, i think.

    so the fucking droughts are for grains, but not for algea. i just don’t fucking know. i just don’t get it. it must be me.

  2. I think all these articles about biowhatever are a hoot. I don’t know what it is but the media so easily buys into any “green” nonsense that is available.

    It’s Richard Branson, therefore it must be possible.

    Aside from the water, apparently all we need to do move everybody out of West Virginia.
    You can chalk this one up in the “will never happen” category.

    Does anybody stop to think for one second that if we even considering this shit then maybe we have a serious fuel-availability problem. And maybe there won’t be double the jet fuel to power a fleet of 36,000 jets in 2025.

    Why does every article project demand out 20 years based on the rate of recent history and then just assume that the fuel supply will be there?


  3. The water problem is easy to fix, get grandma to spit in the ocean, coz every little bit helps.

  4. Branson and the dudes that hang out with him on Caribbean islands watching naked women play volleyball (good work if you can get it) certainly understand resource depletion realities.

    The dilemma of entrepreneurial elites: Torn three ways between a compulsion to profitably do business, an aesthetic/ego that drives them to present a “green” image, and knowledge that — no matter what they do — eventually they will be blamed. Jesus… I’ve almost made them seem sympathetic.
