This work presents some energy considerations concerning a biorefinery case study that has been carried out by the CRB/CIRIAF of the University of Perugia. The biorefinery is the case study of the BIT3G project, a national funded research project, and it uses the lignocellulosic biomass that is available in the territory as input materials for biochemical purposes, such as cardoon and carthamus. The whole plant is composed of several sections: the cardoon and carthamus seed milling, the oil refinement facilities, and the production section of some high quality biochemicals, i.e., bio-oils and fatty acids. The main goal of the research is to demonstrate energy autonomy of the latter section of the biorefinery, while only recovering energy from the residues resulting from the collection of the biomass. To this aim, this work presents the quantification of the energy requirements to be supplied to the considered biorefinery section, the mass flow, and the energy and chemical characterization of the biomass. Afterwards, some sustainability strategies have been qualitatively investigated in order to identify the best one to be used in this case study; the combined heat and power (CHP) technology. Two scenarios have been defined and presented: the first with 6 MWt thermal input and 1.2 MWe electrical power as an output and the second with 9 MWt thermal input and 1.8 MWe electrical power as an output. The first scenario showed that 11,000 tons of residual biomass could ensure the annual production of about 34,000 MWht, equal to about the 72% of the requirements, and about 9600 MWhe, equal to approximately 60% of the electricity demand. The second scenario showed that 18,000 tons of the residual biomass could ensure the total annual production of about 56,000 MWht, corresponding to more than 100% of the requirements, and about 14,400 MWhe, equal to approximately 90% of the electricity demand. In addition, the CO 2 emissions from the energy valorization section have been quantified and the possibility of re-using the CO 2 flow in order to produce methane is described.

“…Their study, however, did not assess the electricity generating capabilities of the gasifier. Patuzzi et al (2016) measured the mass and energy fluxes of four small scale biomass gasifiers deployed in Italy with electric nameplate ratings ranging from 45 to 300 kW. Their study monitored the power plants under 5 to 6 h of normal operation, which may not include quickly varying load profiles that have been observed in field deployable BCTs.…”

“…In certain contexts, such as a remote forest site, small-scale biomass gasifier generators can be an appropriate, clean, and economical technology selection. By using locally available fuel, gasification reduces fuel transportation cost and can simplify fuel supply logistics compared to diesel fuel (Patuzzi et al, 2016). Biomass fuel is widely available, particularly in forest harvest zones, at a substantially lower cost per unit energy than diesel fuel.…”

ABSTRACT. An All Power Labs PP20 gasifier generation set (Berkeley, Calif.) any promising technologies are emerging for the conversion of residual forest waste to useful products. These processes are collectively known as biomass conversion technologies (BCTs) and include processes such as torrefaction, densification, and biochar production. However, the feasibility of BCT projects is highly dependent on the transportation economics of the unprocessed waste biomass (Pan et al., 2008). From a transportation economics standpoint, it is often optimal to place a BCT operation as close to the fuel source as possible. Examples include forest landing sites, at the roadside, or in locations close to forestry operations, such as former sawmills. Although optimal for transportation costs, technological and logistical challenges arise when operating a BCT in remote locations. A key logistical factor for BCT operation is obtaining a reliable source of electricity. Many potential sites do not have access to grid electricity, and a remote power source is therefore required to provide electricity to the BCT. BACKROUNDIn a previous study by Severy et al. (2016), various remote power generation technologies were compared for their potential feasibility for providing power at a remote forest landing site. The technologies evaluated in this study were an organic Rankine cycle (ORC) waste heat recovery device, a thermoelectric generator, a biomass gasifier with an engine generator (All Power Labs Power Pallet, Berkeley, Calif.), a solar PV array with battery storage, and a shaft work power generator. The generation sources were evaluated based on their mobility, footprint, reliability, operational intensity, electrical load following ability, environmental impact, capital cost, operational cost safety, and ease of permitting. The results of the technoeconomic feasibility study concluded that a biomass gasifier was the preferred alternative technology to replace a diesel generator at a BCT site due to its mobility, small footprint, competitive lifecycle cost, and quoted load following abilities (Severy et al., 2016). To validate the results of the feasibility study and extend research on the topic, the goal of this study is to evaluate the suitability of the APL PP20 for powering biomass conversion technologies in the greater Pacific Northwest area. The objectives are to measure the power output and load following capabilities, quantify the emission rates, and provide electricity to a remote BCT that has a fluctuating load. By conducting these tests, the authors can verify whether this gasifier generator is a technically-viable alternative to a diesel generator at offgrid locations. GASIFIER AS AN ELECTRICAL POWER SOURCEGasification technology has been used for decades (Ghosh et al., 2006). However, due to relatively recent technology improvements, there has been an increase in development and interest in the technology. Ahrenfeldt et al.

Gasification technology presents one option for energy-conversion technique from woody biomass contaminated by radionuclides released in March 2011 during the Fukushima Dai-ichi Nuclear Power Plant accident. The gasification process converts carbonaceous materials into combustible gases, carbon dioxide, and residues. Owing to their smallscale distributed configuration, woody biomass gasification plants are suitable for gasifying Japan's biomass and have been installed increasingly in Japan recently. This chapter reviews current trends of gasification and life cycle assessment (LCA) of total systems, including gas cleaning.
