Cover Story: The dynamic control of solar hybrid biomass gasification was performed for continuous day and night operation. Using concentrated solar energy results in reducing CO2 emissions while saving biomass resources and producing more high-quality syngas, compared with conventional processes requiring partial feedstock combustion. Hybrid solar gasification appears promising for stable and continuous operation under fluctuating solar irradiation. A model predictive control algorithm was implemented at a small and industrial scale. The reactor temperature (1200 K) and syngas production rate (1000–1300 NL/s) were maintained stable round-the-clock. The feasibility of dynamic control of the solar-hybrid gasifier was demonstrated for determining annual process performance. Solar-only gasification and hybridization with external heating were also assessed. View this paper
