Synopsis: CUBE 2.0 was designed to facilitate examination of the sources and magnitude of uncertainties in GHG emissions resulting from cultivation, preparation, and delivery of biomass feedstocks and to allow exploration of the sensitivity of net emissions to these various uncertainties. The model determines the life cycle GHG emissions of biomass feedstocks from planting the biomass to delivery to the bioenergy plant gate ("farm-to-hopper”). Included are emissions associated with feedstock production, transportation, and processing (corn grain, corn stover, switchgrass [SG], mixed prairie biomass [MPB], and hybrid poplar) and two biomass residues (forest residue and mill residue). This model is an update to the CUBE 1.0 model released in March 2010 Updates to the model include several additions and corrections to CUBE 1.0. In particular, the functionality and scope have been expanded by adding two additional feedstocks (corn stover and hybrid poplar) and by increasing the number and complexity of processing and transport choices. Major modifications are summarized in corresponding Model Documentation. A free Analytica player for viewing and using this model can be downloaded from Lumina Decision Systems at:
