I suspect what is holding back some big investors such as other energy companies, etc., is minimal profits the other enzyme-based cellulosic ethanol producers are getting at today's ethanol prices. From the economical analysis from BLuefire's website, it seems their concentrated acid-based process should do better than most other producers. However, until Bluefire builds a full-sized plant, and further proves their process out, many, including Chinese investors seem reluctant to advance the remaining $30M needed to begin construction at Fulton, MS. I am assuming that plant site is still available, and the loan promised by the EXIM Bank of China is still being offered as soon as the final $30M is obtained.
