High On Pond Scum

Two weeks ago, a Gulfstream G-450 loaded with journalists and executives from Honeywell’s energy division, UOP, departed from Morristown, New Jersey and touched down at Le Bourget Airport after an “utterly unremarkable” flight.

The purpose of the flight, which retraced Charles Lindbergh’s historic 1927 pond crossing, was to prove for the Paris Air Show the viability of the fuel that held them aloft: 50-50 blend of jet fuel and a biofuel derived from camelina, a seed plant. The blend saved 5.5 metric tons of carbon emissions for the flight compared to straight jet fuel, according to the company. (A 747 crossed the Atlantic several days later on a similar biofuel blend.)

Jim Rekoske, vice president and general manager of Renewable Energy and Chemicals for UOP, said that recent events had brought biofuels “one step closer to commercial use that will help the aviation community reduce its carbon footprint and dependence on crude.”

Not everyone was impressed.

“It would have been a technical shocker only if the fuel didn’t work,” said James Bartis, a biofuels expert at the Rand Corp.

Aviation biofuels derived from camelina, jatropha, algae and other sources have been hyped, and funded, for years as petroleum alternatives that are just years away from widespread adoption. This view was affirmed in June when the oil-product standards body ASTM International granted preliminary approval for commercial airlines to use aviation biofuels (also known as BIO SPK).

The approval comes as airlines are facing pressure, particularly in Europe, to reduce their emissions, which account for 2 percent of global carbon emissions.

Despite the obvious appeal of biofuels for energy security and environmental sustainability, analysts, researchers and even some within the industry remain skeptical that large numbers of passengers will be kept aloft by pond scum and scrub plants anytime soon.
