Camelina sativa could be a potential feedstock to help meet the U.S. biodiesel production goal of 36 billion gallons by 2022, as set forth by Energy Independence and Security Act of 2007. This research is focused on assessing the energy balance and greenhouse gas (GHG) emissions of camelina biodiesel production in the Pacific Northwest (PNW) region of the U.S. Field data were collected from a camelina farm in the region, and crushing and transesterification data were measured using facilities at the University of Idaho. It was estimated that use of camelina biodiesel reduces GHG emissions by 69% compared to 2005 baseline diesel. However, camelina biodiesel does not meet the ASTM D6751 specification for oxidative stability without an additive. Camelina has a smaller seed size compared to canola and required 23% more energy for crushing. The net energy ratio for camelina biodiesel was found to be 3.6, and the fossil energy ratio was found to be 4.2. From an agronomic standpoint, camelina can be incorporated into low rainfall areas of the PNW as a rotational crop. Wheat areas of the PNW with annual rainfall of 19 to 38 cm that currently incorporate fallow into their rotations were considered as potential areas for camelina production. There were 846,500 ha (2.1 million acres) of land meeting the criteria in the region that could potentially produce 443.0 million L of biodiesel (117.1 million gal) and 1.2 billion kg of meal per year. This is 12.1% of the approved amount of camelina meal that could be used in livestock feed within the PNW. It was concluded that camelina biodiesel qualifies as an advanced biofuel, and camelina meal has potential to be consumed locally as a feed mix for livestock.
