Non-sustainable biofuel are inefficient, unsustainable sources of energy and require large landmasses that are mostly grown for human consumption. Sustainable biofuel are derived from non-food crops, requiring small landmasses and proportionally less fertilizer, water and energy. Using first-generation feedstocks to produce biofuel creates a scenario where two different applications—food source and fuel source—compete against one another, effectively driving up food prices (especially in developing countries). This food-versus-fuel issue is primarily related to agricultural ethanol, and it is of lesser significance for agricultural related biodiesel. Commercial passenger jets cannot use ethanol, so the food displacement issue is primarily a concern for first-generation ground transport applications. Algae: Simple, photosynthetic plants lacking leaves and roots Babassu: A native-growing Brazilian tree also with a high-oil-yield nut Camelina: A plant with naturally high oil content Halophytes: Salt marsh grasses and other saline habitat species Jatropha: A widely distributed tropical plant featuring a high-oil-yield nut Switchgrass: A hardy, drought-resistant grass Production costs per gallon are improving—bringing economic viability clearly into view. Because they are grown regionally, second-generation feedstocks have the potential to deliver entirely new fuel supply models. We’re focusing our low-carbon alternative fuels development efforts on new sustainable biofuel from second-generation feedstocks because they present an economically viable opportunity to sustainably power the world’s commercial aircraft fleet. In addition to offering greater environmental and socio-economic benefits, the bottom-line implications of second-generation biofuel are increasingly promising.
