In traditional hybrid solar energy and natural gas systems, solar energy is utilized based on photovoltaic or solar thermal conversion, and natural gas is utilized using combined cycle. This system represents a simple combination because the irreversible losses in conventional methods for solar energy and natural gas harvesting still exist in this system. Here, we proposed a novel hybrid system featuring the combination of solar-driven photothermal reforming of natural gas to produce syngas (H₂ and CO) and hybrid power generation from the solid oxide fuel cell and the gas turbine. The irreversible losses are lowered in three ways in this system. First, by producing syngas from solar energy and natural gas, the irreversible loss from the combustion of natural gas in the traditional system is lowered; moreover, intermittent solar energy is stored in the form of chemical energy. Secondly, compared to traditional solar thermochemical reforming, which requires a reaction temperature as high as ~ 900°C, photothermal reforming has been demonstrated to be performed at much lower temperatures and resultantly to achieve higher energy conversion efficiency, for example, in our prior work (Chem. Eng. J., 2022, 446, 137437). Thirdly, by the combination of the solid oxide fuel cell and the gas turbine, the cascaded utilization of the chemical energy of the syngas is realized. Consequently, simulations show that an absolute 10% increase in energy efficiency has been achieved by our proposed system compared to traditional hybrid systems.
