I was very excited to present the work I have been doing assessing the potential value of the Low Carbon Fuel Standard credits, Renewable Identification Numbers and carbon offsets to biogas projects. To put this value into to context, I modeled the returns that could be expected from a 5,000 cow dairy digester whose biogas is cleaned and used as transportation  fuel. Here is the summary slide:

Weisberg Biocycle 2013 Presentation money shot

This project (with an estimated $11.05 million capital cost) is estimated to have a 7.8% ten year, pre-tax internal rate of return based on the revenue generated by selling transportation fuel, tipping fees, nutrients and bedding. The presentation explores the returns added by selling all three environmental credits under a variety of potential price scenarios.
