“…NPV is most appropriate for comparisons of mutually exclusive projects for which capital costs vary (Couper, 2003;Park, 2011). However, IRR is widely used in the literature for reporting the results of techno-economic analyses Haro et al, 2013;Piccolo and Bezzo, 2009;Zhang et al, 2013), so it is also calculated here.…”

This analysis identifies the sensitivity of the fast pyrolysis and hydroprocessing pathway to facility location. The economic feasibility of a 2000 metric ton per day fast pyrolysis and hydroprocessing biorefinery is quantified based on 30 different state-specific facility locations within the United States. We calculate the 20-year internal rate of return (IRR) and net present value (NPV) for each location scenario as a function of state-and region-specific factors. This analysis demonstrates that biorefinery IRR and NPV are very sensitive to bio-oil yield, feedstock cost, location capital cost factor, and transportation fuel market value. The IRRs and NPVs generated for each scenario vary widely as a result, ranging from a low of 7.4% and -$79.5 million in Illinois to a high of 17.2% and $165.5 million in Georgia. The results indicate that the economic feasibility of the fast pyrolysis and hydroprocessing pathway is strongly influenced by facility location within the United States. This result could have important implications for cellulosic biofuel commercialization under the revised Renewable Fuel Standard.

“…The biobased production of olefins is a promising way to produce plastics from biomass. The integrated production of multiple products from biomass is currently discussed for future-expected thermochemical biorefineries using dimethyl ether (DME) as platform chemical, as for example using the DME (hydro)carbonylation route for the production of ethanol, methyl acetate DME and hydrogen from syngas (synthesis gas) [2].

The conversion of low-grade lignocellulosic biomass such as residual wood or straw to synthetic fuels and chemicals is currently being developed within the bioliq® concept (at the Karlsruhe Institute of Technology -KIT, Germany). The aim of this study is to model and assess three different synthesis process concepts with DME (dimethyl ether) as a platform chemical. The process concepts are designed and assessed using existing technologies, as well as the previous studies for pyrolysis and gasification sections. The respective considered products in the selected concepts are synthetic gasoline, ethylene and propylene.Using biomass for these applications can reduce fossil CO2 emissions by replacing non-renewable carbon sources. The techno-economic assessment concludes that total energy efficiency ranges between 37.5% and 41.1% for the production of gasoline and olefins, respectively. The resulting specific production cost in the gasoline concept is 72% higher than the current market price. In the olefins concept the difference to the current market prices of ethylene and propylene is reduced to 40%. The specific production costs in the gasoline and ethylene concept are 59% higher than current market prices. The possibility to sequestrate CO2 within the considered concepts at costs of 39 €/t allow additional revenues from sequestrated CO2. In order to meet current market prices, the implications of sequestrated CO2, mineral oil tax reduction and the combination of both kinds of subsidies are evaluated in this study. Keywords:Techno-economic assessment; Thermochemical biorefinery; Process design and simulation; Dimethyl ether (DME); Gasoline; Olefins IntroductionThe European Union enforces the use of biomass derived transportation fuels by setting a share of 10% biofuels for 2020 [1]. Synthetic gasoline produced from biomass is one of the most promising alternative fuels since it can be used in regular internal combustion engines without modifications. Furthermore biomass can reduce fossil CO 2 emissions by replacing nonrenewable carbon sources in other applications, such as in the chemical industry. The biobased production of olefins is a promising way to produce plastics from biomass. The integrated production of multiple products from biomass is currently discussed for future-expected thermochemical biorefineries using dimethyl ether (DME) as platform chemical, as for example using the DME (hydro)carbonylation route for the production of ethanol, methyl acetate DME and hydrogen from syngas (synthesis gas) [2]. In this study we assess the production of olefins and gasoline separately, i.e. two different concepts, and also the co-production (multiproduction) of gasoline and ethylene.
