What’s DOE doing about feedstock costs? The Digest’s 2016 Multi-Slide Guide to DOE’s Feedstock programs

August 11, 2016 |

Is it just cost that bedevils industrial biotechnology in bringing fuels technologies to sacel. Not just, says BETO program director Jonathan Male, who adds that a DOE “Tiger Team” indetified many other factors:

What about these?

Use of equipment that was originally designed for different feedstock types. Insufficient piloting of feedstock handling or pretreatment equipment using the actual feedstock. Lack of understanding of feedstock characteristics (viz. bulk density, angle of repose, effect of moisture, abrasiveness, regional soil composition, inert materials and ash content, etc.) and their effect on equipment and conversion processes. Inability to produce and maintain a consistent particle size distribution that allow for optimized operations. Inadequate removal of dirt and rock from the feedstock leading to equipment erosion, breakage, and fouling. Process interruption due feedstock bridging, bird-nesting, binding or plugging. Creation of fines and/or the inability to remove fines resulting in yield loss, inhibitor creation, and fouling. Need for improvements in feedstock logistics (collection methods, moving bales, clean storage of bales, fire detection/suppression, etc.)

And what’s DOE doing about it all? Jonathan Male gave this survey of DOE activities from A to Z at the 2016 ABLC Feedstocks event. His presentation is here.
