A Spatial-Economic Optimization Study of Swine-Waste Derived Biogas Infrastructure Design in North Carolina

This report by the Nicholas Institute for Environmental Policy Solutions and the Duke Carbon Offsets Initiative highlights a comparative modeling analysis considering individual and centralized approaches for meeting North Carolina's Renewable Energy and Energy Efficiency Portfolio Standard (REPS) mandate for swine. It finds that injecting biogas collected from an optimized network of farms into the natural gas pipeline could be a cost-effective approach to meeting the state REPS.
