Green Options

Imagine a grass crop, grown on marginal, non-food bearing land without pesticides or much fertilizer, that, when harvested, produces an oil that needs almost no processing to be substituted for diesel fuel.

Much attention has been given to producing ethanol from non-food crops like grasses, but the ability to produce something indistinguishable to diesel from grass could be a game-changer. It would require almost no infrastructure change and could fuel all of the existing long-haul trucks on the road without modification.

Farmers in Northern Queensland, Australia, are investigating another approach to producing renewable fuel: growing diesel trees. As weird as that sounds, it’s real, and it isn’t a scientific breakthrough. We’ve actually known about the trees for over 300 years.

As Treehugger reported earlier this week, farmers in the more tropical region Queensland purchased about 20,000 Brazilian diesel trees, or Copaifera langsdorfii, with the intention of having a living oil-mine in 15 years. According to Purdue University, a 100 acre plot of trees could produce about 25 barrels of oil per year.
