Presentation Transcript

  1. Sustainable biofuel operating space: multi-criteria assessment and multi-objective optimization

  2. Bioenergy Life-Cycle Analysis (4.6.2) • Primary drivers for bioenergy include reducing demand for petroleum and emissions of greenhouse gases. • Life-cycle analysis (LCA) estimates the overall contribution of bioenergy system towards meeting these objectives. • LCA evaluates the entire process (i.e., field to wheels) including all upstream and downstream energy and material inputs and associated greenhouse gas emissions • Evaluate bioenergy pathways that are cost-effective and sustainable relative to net greenhouse gas impact, long-term soil quality, and ecosystem impacts.

  14. Conclusions • Multi-objective optimization can provide promising candidate biofuel crop landscape configurations for multi-criteria assessment of sustainability. • Spatially-explicit variables (e.g. carbon and yield) related to LCA assessment • Spatially-explicit modeling map can be used to calculate the distance from crop fields to biorefinery and transportation cost for LCA. www.glbrc.org
