Techno-economic and uncertainty analysis of Biomass to Liquid (BTL) systems for transport fuel production

Techno‐economic analysis of co‐production of 2,3‐butanediol, furfural, and technical lignin via biomass processing based on deep eutectic solvent pretreatment

“…Although such 2,3‐BDO MBSP is similar to the above assumed market price, unstable market prices of raw materials and variations of economic analysis assumptions could result in uncertainties. To evaluate parameter effects and the uncertainty level of TEA, sensitivity and uncertainty analyses have been widely used for economic analysis …”

“…To evaluate parameter effects and the uncertainty level of TEA, sensitivity and uncertainty analyses have been widely used for economic analysis. 21,22 The main objective of this study was to evaluate the technoeconomic feasibility of the high-solid biomass conversion into 2,3-BDO and co-products (i.e., furfural, lignin) based on DES pretreatment as reported in our prior study. 14…”

A comparative techno‐economic assessment of three bio‐oil upgrading routes for aviation biofuel production

“…Achieving accuracy in capital cost estimation is a major challenge at the early stage of project definition, and significant uncertainty reduction can only be attained via obtaining capital cost data from a commercial biomass to liquids plant, which is not presently available. Furthermore, changes in feedstock prices represent a significant source of uncertainty; to diminish volatilities in the feedstock price, the agreement of a longstanding biomass procurement deal with determined quantities and charges should be pursued with an agricultural or forest management corporation . The raw material expenditures (catalysts, methane, oxygen, etc) and the electricity prices have a slightly greater effect on the ZC route due to the high price of zeolite catalyst and the increased power generation.…”

“…Furthermore, changes in feedstock prices represent a significant source of uncertainty; to diminish volatilities in the feedstock price, the agreement of a longstanding biomass procurement deal with determined quantities and charges should be pursued with an agricultural or forest management corporation. 81 The raw material expenditures (catalysts, methane, oxygen, etc) and the electricity prices have a slightly greater effect on the ZC route due to the high price of zeolite catalyst and the increased power generation. In addition, the estimate for the MJSP of the most optimistic scenario can be calculated from the accumulated effect of the variable changes.…”

Impacts of uncertain feedstock quality on the economic feasibility of fast pyrolysis biorefineries with blended feedstocks and decentralized preprocessing sites in the Southeastern United States

“…In this study, the techno-economic analysis (TEA) was used to assess the economic feasibility of two biorefinery systems (traditional centralized system vs. decentralized depot system) using two biomass feedstocks-forest residues and switchgrass (Patel et al, 2016;Sorunmu et al, 2020). TEA of biofuel production has been applied to alternative biomass conversion technologies and biomass feedstock types (Beal et al, 2015;Bridgwater et al, 2002;Dang et al, 2018;Dimitriou et al, 2018;Dutta et al, 2011Dutta et al, , 2015Klein-Marcuschamer et al, 2011;Kumaravel et al, 2012;Mohsenzadeh et al, 2017;Patel et al, 2016;Pfromm et al, 2010;Pirraglia et al, 2010;Sahoo et al, 2019;Segurado et al, 2019;Swanson, Platon, Satrio, & Brown, 2010;Tao et al, 2017;Wright, Daugaard, Brown, & Satrio, 2010). For example, Wright et al (2010) investigated the economic feasibility of fast pyrolysis biofuel from corn stover with two scenarios: one used onsite hydrogen generation from bio-oil and the other used merchant hydrogen from natural gas reforming for its upgrade.…”
