Life Cycle Inventory of Biodiesel and Petroleum Dieseli
Life cycle studies require a lot of thoughtfulness, hard work and patience. We have been fortunate enough to have all of these. The core team of workers comes from a variety of organizations. The ability to pull off this kind of collaboration among so many groups is a tribute to each of the individual organizations.
From the U.S. Department ofEnergy’s National Renewable Energy Laboratory…
John Sheehan, who initiated and organized this whole effort at the start, provided detailed process modeling for the soybean crushing and biodiesel production technologies. K. Shaine Tyson, NREL Project Manager for DOE’s Biodiesel Program, provided overview and management for the work (and, more importantly, shared her insights based her experienceconducting a life cycle study for ethanol).
