Summary: Concentrating solar direct-steam-generation (DSG) technology is used to directly convert solar energy and water into power, contributing to a zero-carbon future. However, the intermittence of meteorological irradiation and instability of flow boiling pose challenges to the operation of the system. A transient coupled analysis model was established to investigate the relationship among irradiance, thermohydraulic and two-phase flow pattern in a parabolic trough collector direct-steam-generation (PTC-DSG) loop.

Summary: Solar thermochemical gasification can produce sustainable fuels from biomass, with the potential to reduce CO2 emissions. Hybrid solar-autothermal gasification with oxygen injection and additional biomass supply can improve gasification efficiency and control H2:CO ratio for in-situ combustion. Higher temperatures (1300 degrees C) lead to increased H2 and CO yields, demonstrating the advantages of solar-driven gasification processes.

Summary: This paper presents the modeling and dynamic control of a solar hybrid thermochemical reactor for syngas production. A thermodynamic equilibrium-based reactor model is proposed using the Cantera toolbox. A model-based predictive controller (MPC) is developed to maintain the reactor temperature and stability by adjusting mirrors or burning biomass. The MPC controller outperforms a reference controller and image-based DNI forecasts reduce error values, while an interpolation function reduces optimization time.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
