The seeds of a lowly weed could cut jet fuel’s cradle-to-grave carbon emissions by 84 percent.

David Shonnard analyzed the carbon dioxide emissions of jet fuel made from camelina oil over the course of its life cycle, from planting to tailpipe. “Camelina jet fuel exhibits one of the largest greenhouse gas emission reductions of any agricultural feedstock-derived biofuel I’ve ever seen,” he said. “This is the result of the unique attributes of the crop–its low fertilizer requirements, high oil yield, and the availability of its coproducts, such as meal and biomass, for other uses.”

Camelina sativa originated in Europe and is a member of the mustard family, along with broccoli, cabbage and canola. Sometimes called false flax or gold-of-pleasure, it thrives in the semi-arid conditions of the Northern Plains; the camelina used in the study was grown in Montana.

Oil from camelina can be converted to a hydrocarbon green jet fuel that meets or exceeds all petroleum jet fuel specifications. The fuel is a “drop-in” replacement that is compatible with the existing fuel infrastructure, from storage and transportation to aircraft fleet technology…

Because camelina needs little water or nitrogen to flourish, it can be grown on marginal agricultural lands. “Unlike ethanol made from corn or biodiesel made from soy, it won’t compete with food crops,” said Shonnard. “And it may be used as a rotation crop for wheat, to increase the health of the soil…”

I’m a firm advocate of running biofuel wherever and whenever possible. Sounds like a win-win situation to me. It’s even high in omega-3 fatty acids.
