Conversion to bio coal

Submitted by hamako (not verified) on May 31, 2012 - 3:18pm.

Richard, there is now another solution on the horizon - an exothermic, low-cost process, requiring very little additional energy, which converts the sewer sludge with 80% moisture content directly into a high-grade bio coal powder with an energy content of hard coal. It can be gassified and used in combined cycle power plants with over 60% thermal efficiency. With California's FIT, this could become a money maker for Hyperion!
