%X Producing methanol in sun-rich regions like Africa that are also characterized by water scarcity presents a substantial challenge to sustainable fuel synthesis. To address this challenge, an innovative and integrated approach has been developed that involves capturing both water and carbon dioxide directly from the ambient atmosphere using advanced amine-based direct air capture (DAC) technologies. This method not only provides a sustainable source of CO2 but also extracts valuable water vapor from the air in a water-positive manner. The captured water and CO2 are then fed into a high-temperature solid oxide electrolysis (SOE) system, where they are co-electrolyzed to produce syngas—a mixture of hydrogen and carbon monoxide. This presentation focuses on the design and optimization of SOE system for syngas production. The syngas serves as the essential feedstock for downstream methanol synthesis, enabling efficient conversion into green methanol. By harnessing abundant solar energy to power the entire process, this integrated technology effectively overcomes water limitations and utilizes renewable energy resources, thereby facilitating a sustainable and climate-neutral pathway for methanol production in arid, sun-rich regions like Africa.
