“…Huang et al (2017) studied the catalytic supercritical water gasification of glucose over Ni/Zr(Ce,Y)O2-δ catalysts at 500°C, 23-24 MPa, and feed concentration of 10 wt.%, and reported that carbon gasification efficiency was improved as Ni concentration was increased from 0.1 to 0.7. In this same work, a hydrogen yield of 22 mol kg -1 was obtained using Ni0.5Zr0.8Y0.2O2.8 (NZY582) catalyst which was 10 times greater than that of the catalyst-free conditions.…”

“…As an alternative to the conventional gasification, the supercritical water gasification (SCWG) process uses water over 22 MPa and 374 • C (critical point) as the gasifying agent to decompose the wet biomass feedstock, allowing to achieve a much higher ratio of gasification and hydrogen generation [1][2][3][4][5]. Although the high cost of the feedstock is a challenging issue in utilizing the SCWG, low-cost feedstocks like sewage sludges are widely available to be used as a heavily moisture-laden feedstock in this process [6][7][8][9]. Organic wastewater and kitchen waste are considered as possible sewage sludge which do not need any drying steps, resulting in economically beneficial characteristics in the production of hydrogen [10].…”

This paper proposes an innovative hydrogen-based hybrid renewable energy system (HRES), which can be used to provide electricity, heat, hydrogen, and water to the small community in remote areas. The HRES introduced in this study is based on the integration of solar power generation, hydrogen generation from supercritical water gasification (SCWG) of wet biomass feedstock, hydrogen generation from solar water electrolysis, and a fuel cell to convert hydrogen to electricity and heat. The wet biomass feedstock contains aqueous sludge, kitchen waste, and organic wastewater. A simulation model is designed and used to investigate the control strategy for the hydrogen and electricity management through detailed size estimation of the system to meet the load requirements of a selected household area, including ten detached houses in a subject district around the Shinchi station located in Shinchi-machi, Fukushima prefecture, Japan. As indicated by results, the proposed HRES can generate about 47.3 MWh of electricity and about 2.6 ton of hydrogen per annum, using the annual wet biomass consumption of 98 tons, with a Levelized Cost of Energy (electricity and heat) of the system at 0.38 $/kWh. The implementation of the proposed HRES in the selected residential area has GHG emissions reduction potential of about 21 tons of CO2-eq per year.

Sub- and Supercritical Water Gasification of Rice Husk: Parametric Optimization Using the I-Optimality Criterion

et al. 2021

In this study, rice husk biomass was gasified under sub- and supercritical water conditions in an autoclave reactor. The effect of temperature (350–500 °C), residence time (30–120 min), and feed concentration (3–10 wt %) was experimentally studied using the response surface methodology in relation to the yield of gasification products. The quadratic models have been suggested for both responses. Based on the models, the quantitative relationship between various operational conditions and the responses will reliably forecast the experimental outcomes. The findings revealed that higher temperatures, longer residence times, and lower feed concentrations favored high gas yields. The lowest tar yield obtained was 2.98 wt %, while the highest gasification efficiency and gas volume attained were 64.27% and 423 mL/g, respectively. The ANOVA test showed that the order of the effects of the factors on all responses except gravimetric tar yield follows temperature > feed concentration > residence time. The gravimetric tar yield followed a different trend: temperature > residence time > feed concentration. The results revealed that SCW gasification could provide an effective mechanism for transforming the energy content of RH into a substantial fuel product.
