“…As anticipated, the plant performance summarized in Table 3 comes from the preliminary experimental runs (two different runs, carried out in early 2018), with a gasification process which still requires a careful optimization of the operating procedures and parameters. In any case, the preliminary results seem very promising and they are comparable with those reported in literature [37]: for an ER of 0.35-0.40, the cold gas efficiency of air-blown BFB biomass gasification units are typically in the range of 0.45-0.65, whereas the carbon conversion efficiency is in the range of 0.6-0.9.…”

In order to limit global warming to around 1.5–2.0 °C by the end of the 21st century, there is the need to drastically limit the emissions of CO2. This goal can be pursued by promoting the diffusion of advanced technologies for power generation from renewable energy sources. In this field, biomass can play a very important role since, differently from solar and wind, it can be considered a programmable source. This paper reports a techno-economic analysis on the possible commercial application of gasification technologies for small-scale (2 MWe) power generation from biomass. The analysis is based on the preliminary experimental performance of a 500 kWth pilot-scale air-blown bubbling fluidized-bed (BFB) gasification plant, recently installed at the Sotacarbo Research Centre (Italy) and commissioned in December 2017. The analysis confirms that air-blown BFB biomass gasification can be profitable for the applications with low-cost biomass, such as agricultural waste, with a net present value up to about 6 M€ as long as the biomass is provided for free; on the contrary, the technology is not competitive for high-quality biomass (wood chips, as those used for the preliminary experimental tests). In parallel, an analysis of the financial risk was carried out, in order to estimate the probability of a profitable investment if a variation of the key financial parameters occurs. In particular, the analysis shows a probability of 90% of a NPV at 15 years between 1.4 and 5.1 M€ and an IRR between 11.6% and 23.7%.

“…2007;Smidt et al 2010) at the reactor bottom when only refuse-derived fuel is gasified. Aside from the research at laboratory scale, the co-gasification has also been advanced to pilot scale (Pio et al 2017(Pio et al , 2020. The co-gasification of refuse-derived fuel and pine biomass was conducted in a 80 kW th bubbling fluidized bed reactor associated with the assessment of several parameters such as lower heating value of producer gas, efficiency of cold gas, and carbon conversion.…”

Dwindling fossil fuels and improper waste management are major challenges in the context of increasing population and industrialization, calling for new waste-to-energy sources. For instance, refuse-derived fuels can be produced from transformation of municipal solid waste, which is forecasted to reach 2.6 billion metric tonnes in 2030. Gasification is a thermalinduced chemical reaction that produces gaseous fuel such as hydrogen and syngas. Here, we review refuse-derived fuel gasification with focus on practices in various countries, recent progress in gasification, gasification modelling and economic analysis. We found that some countries that replace coal by refuse-derived fuel reduce CO 2 emission by 40%, and decrease the amount municipal solid waste being sent to landfill by more than 50%. The production cost of energy via refuse-derived fuel gasification is estimated at 0.05 USD/kWh. Co-gasification by using two feedstocks appears more beneficial over conventional gasification in terms of minimum tar formation and improved process efficiency.

“…For a single-staged reactor, the pyrolysis and gasification zones are packed into one reactor (Figure 1a). A single-staged gasifier includes a fixed bed gasifier [11,12], fluidized bed gasifier [13,14], and entrained flow gasifier [15,16]. A multi-staged reactor system is configured in two ways: a single reactor with separate, controlled pyrolysis and gasification zones, and separate pyrolysis and gasification reactors connected in series (Figure 1b).…”

Interest in converting waste into renewable energy has increased recently due to concerns about sustainability and climate change. This solid waste is mainly derived from municipal solid waste (MSW), biomass residue, plastic waste, and their mixtures. Gasification is one commonly applied technology that can convert solid waste into usable gases, including H2, CO, CH4, and CO2. Single- and multi-staged reactors have been utilized for solid waste gasification. Comparison in reactor dimensions, operating factors (e.g., gasification agent, temperature, and feed composition), performance (e.g., syngas yield and selectivity), advantages, and disadvantages are discussed and summarized. Additionally, discussion will include economic and advanced catalysts which have been developed for use in solid waste gasification. The multi-staged reactor can not only be applied for gasification, but also for pyrolysis and torrefaction.
