Biomass availability source data is from the University of Washington Rural Technology Initiative Group (RTI) as outlined within Berry and Sessions (2018a). The basic methods are illustrated within this text but the reader is encouraged to review Berry and Sessions (2018a,b) for additional detail.…”

“…The study of transportable facility design to produce higher value wood products (biochar, torrefied wood, briquettes, pellets) is less studied (Chai and Saffron, 2016;Berry and Sessions, 2018a, b). Berry and Sessions (2018a) take this concept a step further by optimizing strictly transportable facilities [13,,000 bdmt yr -1 (15,000-50,000 bdt yr -1 )] for a biochar facility finding optimal time between moves being 1 to 2.5 years. While suffering from economies of scale issues due to low production and low efficiency plant operations, the transportable system may yield a viable supply chain.…”

ABSTRACT. Transportable biomass conversion facilities producing biochar, briquettes, and torrefied wood are modeled and optimized for five different sub-regions within the Pacific Northwest. Subregional case studies in Quincy, California; Lakeview, Oregon; Oakridge, Oregon; Port Angeles, Washington; and Warm Springs, Oregon, are to fuel price sensitivity, torrefied wood was the most sensitive as its conversion process was most energy intensive (±12%-13%) and biochar least sensitive (±3-5%).Transportation accounted for 5% to 30% of the fuel price variation due to diesel prices depending on product and region. When including grid-connectivity, cost reductions were approximately 6%-7% for biochar, 27%-29% for briquettes and 33%-38% for torrefied wood. These findings indicate biochar as the most likely candidate for a transportable conversion system given its relatively low power consumption

Economic analysis of forest residues supply chain options to produce enhanced‐quality feedstocks

Woody biomass feedstock that is both high quality and low cost has become increasingly important for the bioenergy and bioproducts industries. Logging generates forest residues – low‐quality feedstock – and additional operations that also incur additional costs, such as biomass sorting and treetops processing (BSTP), micro‐chipping, and screening, which are required to improve the feedstock's quality. Considering recent developments in technologies and BSTP to generate high‐quality feedstocks, economic models were developed in this study to estimate various forest‐residue logistics operational costs and to analyze the economics of delivering feedstocks to biomass conversion technology (BCT) sites near woods or power plants located far away in the form of chips, hog fuel, and bales. The results show that the cost of BSTP can vary between $30 and $82/ODMT (oven dry metric ton) based on the biomass sorting intensity. The most economical way to deliver forest residues was transporting processed stem‐wood from landings to near‐wood BCT sites and comminuting it into woodchips there (~$20/ODMT, assuming a one‐way (32 km) road distance and no cost of BSTP at landings). Grinding slash at the landing and transporting ground‐biomass (i.e., hog fuel) to a plant (< 22 km away) was more economical than transporting bales from landings and grinding at the plant. The economic feasibility of baling and BSTP requires a substantial productivity improvement or recognition and incorporation of benefits including reduced wildfire risk and improved forest health. High bulk density and strong shape of forest residues/slash bales compared to hog fuel may provide additional cost benefits during storage, for example through lower handling costs, which can be studied in the future. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd
