Most pioneer cellulosic biofuel plants worldwide failed to achieve designproduction capacity, and many have shut down. The major causes of failure to achieve the design throughput include: (i) feedstock logistics causing significant variability of the properties of raw biomass delivered to the plants, (ii) inability of the plants to handle the variability in biomass properties, which leads to low feedstock throughput and low product yield, (iii) integration of feedstock preprocessing unit operations with downstream conversion processes at the plants, which leads to unreliable operation as operating difficulties in one area can cause process upset or shutdown of the other.ExxonMobil Research and Engineering Company, via a technical services agreement, engages Idaho National Laboratory (INL) to provide general industry knowledge, best practices, and lessons learned in cellulosic ethanol plant design, project execution, and operations. INL will also assess publicly proposed cellulosic plant designs. The scope of work will be accomplished in three tasks: Task 1, Communicate industry knowledge; Task 2, Present high-level lessons learned; Task 3, Provide an engineering assessment of publicly proposed ethanol plant designs.This Task 1 report provides a high-level summary of general industry knowledge, best practice, and lessons learned in biomass feedstock logistics and integration with bioconversion processes. Based on INL's more than 15 years of research and development (R&D) in biomass feedstock preprocessing and the author's more than 40 years of R&D, engineering design and cellulosic ethanol plant operating experience and published research results related to biomass harvest, collection, transportation, and storage, the following observations can be drawn:
