ABSTRACT Syngas rich in hydrogen, generated through renewable‐powered co‐electrolysis of water (H 2 O) and carbon dioxide (CO ) using solid oxide electrolysis cells (SOEC), have gained significant attention due to its high efficiency conversion rates. This method offers a promising solution for mitigating global warming reducing CO emissions by enabling the storage intermittent renewable energy. study investigates solar‐integrated H O via SOEC produce hydrogen‐rich syngas, which is then utilized methanol synthesis series heat exchangers compressors. Parabolic dish solar collectors supply thermal energy, while photovoltaic modules provide electricity operation. from industrial processes captured combined with steam at inlet co‐electrolysis. The proposed system modeled engineering equation solver software, incorporating mass, exergy balance equations. system's performance analyzed varying key parameters such as direct normal irradiance, exchanger effectiveness, current density, cell temperature, pressure. achieves solar‐to‐fuel 29.1%, production rate 41.5 kg per hour. Furthermore, an economic analysis was conducted determine levelized cost fuel.
