“…The economic assessment aims for determining costs of production for typical syngas and comparing these process configurations. To achieve this goal, this study employs the cost model (Table S4) including total capital investment (TCI), total production cost (TPC), and unit product cost (UPC). , TCI includes fixed capital investment (FCI) and working capital (WC). Also, FCI consists of indirect and direct investments that have to be estimated first.…”

Natural gas shortage, waste treatment, and renewable energy utilization and storage are the common issues in China. This research aims to evaluate a simple and reliable biomass and power-tosyngas process for high-quality syngas production integrating oxygen gasification and water electrolysis. The technical and economic evaluations are successively performed based on the simulation data. The single-stage and two-stage gasifiers are integrated and compared. The results show that the process with a two-stage gasifier has advantages in both technical and cost performances over that with a single-stage gasifier. Then, the optimal values of the operating variables are determined by investigating their effects on syngas composition and yield and the overall energy and exergy efficiencies. Then, by setting appropriate amounts of water for electrolysis and methanation pressures, the process can generate two typical products: thermochemical synthetic biogas (TSB) or synthetic natural gas (SNG). The overall energy and exergy efficiencies of TSB can reach 74.1 and 69.5%, respectively, while those of SNG can achieve 64.8 and 64.1%, respectively. The unit product cost of TSB is about one third of that of SNG, indicating that TSB makes a profit while SNG results in loss. A sensitivity analysis of the cost indicates that the constraints for TSB are much looser than those for SNG to gain profit. Additionally, this study proposes two indicators to characterize the electricity-storage capacities of biomass and syngas. The indicators show that SNG has big advantages over TSB in the specific capacity of electricity storage, and the capacities of SNG and TSB are approximately 52.0 and 4.7 times of the specific energy density of the lithium-ion battery pack in 2019, respectively. The work could be used as a reference for the countries lacking natural gas and valuable to guide the development of a two-stage gasifier, reduction in equipment cost, and evaluation of electricitystorage performance using biofuels.

“…Currently, oil, coal and gas still account for most of primary energy consumption [1]. However, due to the limited supply of fossil fuels, the increasing and fluctuating price of gasoline and environmental concerns brought by greenhouse gas emissions, there has been an increased interest in looking for green and sustainable energy [2]. Liquid fuel derived from biomass provides an opportunity for nations to replace fossil fuel in transportation sector, increase energy independency and reduce greenhouse gas emissions, because the employed raw material is renewable and widespread [3,4].…”

Biobutanol has been emerging as a renewable replacement to overcome fossil fuel limit due to its attractive qualities. The waste resources utilization is an economically feasible and eco-friendly way to produce biobutanol. In this work, the potential of butanol fermentation with sweet potato residue (SPR) obtained from ethanol fermentation was evaluated. To assist sugar release for butanol production by Clostridia acetobutylicum, a pretreatment approach with dilute sulfuric acid was established via response surface methodology. The maximum butanol concentration of 3.77 g/L was obtained at the optimal conditions of pretreatment at 1% (v/v) dilute sulfuric acid, and 115℃ for 30 min. Detoxifying the hydrolysate with XAD-4 resin significantly enhanced butanol fermentation performance, while adding nutritional supplements had no significant influence. The stability of the fermentation process was verified by the 2 L-scale of fermentation, resulting in 7.96 g/L of butanol, 13.42 g/L h of Acetone-Butanol-Ethanol (ABE), and 0.34 g/g of ABE yield, respectively. This study demonstrates a bio-refinery strategy of conversion from waste biomass to energy, confirms the feasibility of utilizing the cost saving SPR as feedstock to produce butanol through fermentation, and provides a novel approach for minimization of environmental pollution.
