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.

Supercritical Water Gasification

AbstractSupercritical water gasification (SCWG) is a very recent technology that allows conversion of organic wastewaters into a fuel gas with a high content of hydrogen and light hydrocarbons. SCWG involves the treatment of organic compounds at conditions higher than those that define the critical point of water (temperature of 374°C and pressure of 221 bar). This hydrothermal process, normally operated at temperatures from 400 to 650°C and pressures from 250 to 350 bar, produces a gas effluent with a high hydrogen content. SCWG is considered a promising technology for the efficient conversion of organic wastewaters, mainly wet biomass, into fuel gas. This technology has received extensive worldwide attention, and many research groups have studied the effect of operation conditions, reaction mechanisms, kinetics, etc. There are some recent reviews about the research works carried out in the last decades, but there is no information or analysis of almost 100 patents registered in relation with this new technology. A revision of the current status of SCWG patents and technologies has been completed based on the Espacenet patent database. The objective of this revision was to set down the new perspectives toward the improvement of this technology efficiency. Patents have been published with regard to process or device improvements as well as to the use of different catalysts. More than 71% of these patents were published since 2009, and a substantial climb in the number of patents on SCWG is expected in the coming years. One of the most important aspects where research is particularly interesting if the integration of renewable energy recovery systems with SCWG processes.

Robust Process

Gasification of organic matter under the conditions of supercritical water (T > 374 °C, p > 221 bar) is an allothermal, continuous flow process suitable to convert materials with high moisture content (<20 wt.% dry matter) into a combustible gas. The gasification of organic matter with water as a solvent offers several benefits, particularly the omission of an energy-intensive drying process. The reactions are fast, and mean residence times inside the reactor are consequently low (less than 5 min). However, there are still various challenges to be met. The combination of high temperature and pressure and the low concentration of organic matter require a robust process design. Additionally, the low value of the feed and the product predestinate the process for decentralized applications, which is a challenge for the economics of an application. The present contribution summarizes the experience gained during more than 10 years of operation of the first dedicated pilot plant for supercritical water gasification of biomass. The emphasis lies on highlighting the challenges in process design. In addition to some fundamental results gained from comparable laboratory plants, selected experimental results of the pilot plant “VERENA” (acronym for the German expression “experimental facility for the energetic exploitation of agricultural matter”) are presented.
