“…CHP by biomass combustion is prevalent, however, gasification is better in terms of electrical efficiency and the acceptable range of biomass qualities (Berggren et al, 2008). The combination of biomass gasification and a gas engine for CHP is a logical choice in the small-scale range and with a biomass to power efficiency potential of 35-40%, which is high compared with conventional technology (Ahrenfeldt et al, 2013;Kumar et al, 2015). In order to reduce the technical problems, a small size (1-10 MW) of the plant could be attractive (Ahrenfeldt et al, 2013;Asadullah, 2014).…”

Staged gasification is identified as a method capable of (i) maximizing energy utilization of the fuel (maximizing char conversion), (ii) minimizing secondary treatment of the gas (by avoiding complex tar cleaning), and (iii) being applied in small (0.…”

Please cite this article as: Farzad S., Mandegari M.A., Görgens J.F. A critical review on biomass gasification, co-gasification, and their environmental assessments. Biofuel Research Journal 12 (2016) HIGHLIGHTSConventional and new gasification technologies were compared. Studies dealing with co-gasification of different feedstocks were summarized. Life cycle assessments of biomass gasification and co-gasification were studied. Gasification is an efficient process to obtain valuable products from biomass with several potential applications, which has received increasing attention over the last decades. Further development of gasification technology requires innovative and economical gasification methods with high efficiencies. Various conventional mechanisms of biomass gasification as well as new technologies are discussed in this paper. Furthermore, co-gasification of biomass and coal as an efficient method to protect the environment by reduction of greenhouse gas (GHG) emissions has been comparatively discussed. In fact, the increasing attention to renewable resources is driven by the climate change due to GHG emissions caused by the widespread utilization of conventional fossil fuels, while biomass gasification is considered as a potentially sustainable and environmentally-friendly technology. Nevertheless, social and environmental aspects should also be taken into account when designing such facilities, to guarantee the sustainable use of biomass. This paper also reviews the life cycle assessment (LCA) studies conducted on biomass gasification, considering different technologies and various feedstocks. ARTICLE INFO ABSTRACT

“…One example is the gasification-based coproduction of heat, electricity, Fischer-Tropsch fuels, dimethyl ether (DME), and hydrogen from biomass feedstocks [1], like switchgrass [2] and black-liquor [3]. Another important example is the integrated production of bioethanol and synthetic natural gas (SNG) with combined heat and power (CHP) production [4].…”

Lignocellulosic ethanol production is often assumed integrated in polygeneration systems because of its energy intensive nature. The objective of this study is to investigate potential irreversibilities from such integration, and what impact it has on the efficiency of the integrated ethanol production.An exergy analysis is carried out for a modeled polygeneration system in which lignocellulosic ethanol production based on hydrothermal pretreatment is integrated in an existing combined heat and power (CHP) plant. The ethanol facility is driven by steam extracted from the CHP unit when feasible, and a gas boiler is used as back-up when integration is not possible. The system was evaluated according to six operation points that alternate on the following three different operation parameters: Load in the CHP unit, integrated versus separate operation, and inclusion of district heating production in the ethanol facility. The calculated standard exergy efficiency of the ethanol facility varied from 0.564 to 0.855, of which the highest was obtained for integrated operation at Complete revised manuscript Click here to view linked References 2 minimum CHP load and full district heating production in the ethanol facility, and the lowest for separate operation with zero district heating production in the ethanol facility. The results suggest that the efficiency of integrating lignocellulosic ethanol production in CHP plants is highly dependent on operation, and it is therefore suggested that the expected operation pattern of such polygeneration system is taken into account when evaluating the potential of the ethanol production.

This article deals with biomass‐based technologies for polygeneration and district heating ( DH ). The relevant technologies for the generation of heat, power, and biofuels are presented in Section 1 taking into account thermochemical, chemical, and biological pathways. In particular, the opportunity of integrating them for polygeneration—also according to the biorefinery concept—is analyzed here. Biomass combined heat and power ( CHP ) systems for DH application have been compared considering size, efficiency, flexibility of operation, and field experience. In Section 2, heat distribution systems have been described taking advantage of the previous analysis on generation technologies and pointing out the existing relation between distribution, generation efficiencies, and DH network temperature. The current trend toward low temperature DH systems has been then extensively analyzed. The effects of the possible variation in the heat demand—both in the short term (i.e., daily to seasonal utilization profiles) and in the medium term (e.g., building refurbishment)—on the DH system operation and efficiency, are presented here. The biomass CHP systems are also discussed in the vision to extend the smart grid concept to thermal networks. As a whole, pilot or real‐plant data and validated theoretical models are used to support the analysis.
