Description
Summary:[Display omitted] •A novel thermal plasma chemical looping for syngas production was developed.•Integration of the process with solar energy was demonstrated.•Aluminium/aluminium oxide pair was chosen as an oxygen carrier in the process.•Syngas quality > 3 was achieved at temperature of 1273 K in the fuel reactor.•Photovoltaic renewable energy share of 39.9% was achieved for the process. In the present article, a new thermal plasma-aided process is proposed and analysed that utilises alumina/aluminium particles to dissociate steam/carbon dioxide blends into high-quality synthetic fuel. The proposed system utilises two reactors namely a synthetic fuel reactor and a thermal plasma particle regenerator following the chemical looping gasification principle. In the former, the gas blend reacts with aluminium particles to produce hydrogen-enriched synthetic fuel and alumina. While in the latter, the alumina is dissociated into oxygen and reduced aluminium. Using thermochemical equilibrium analysis, it was identified that the proposed system can offer a self-sustaining factor of up to 0.18, thermodynamic and exergy efficiency of 0.38 and 0.68, respectively. The system was integrated with photovoltaic energy and a solar share of ≤ 0.5 (with low-capacity battery storage ≤ 4 MWh) and > 0.5 (with high-capacity battery storage
