What is it about?
This article discusses a novel oxy-fuel combustion engine concept with on-board oxygen generation using mixed ionic-electronic conducting membranes. The oxygen is extracted from the air using residual energy from the engine, and a 1D fluid dynamic model is used to predict the interaction of all elements in the system. A carbon capture system is also designed to minimize the effect on engine performance, and this proposed engine concept could allow for 100% carbon capture efficiency.

Perspectives
As researchers dedicated to advancing climate-friendly technologies, we propose a novel oxy-fuel combustion engine concept with on-board oxygen generation using mixed ionic-electronic conducting membranes. This innovative design harnesses residual engine energy to extract oxygen directly from the air, eliminating the need for external oxygen sources. Additionally, we employ a 1D fluid dynamic model to meticulously simulate the interaction of all elements in the system, ensuring optimal performance and efficiency. To address the challenge of minimizing carbon dioxide emissions, we carefully design a carbon capture system that effectively captures CO2 from the combustion exhaust. This system is specifically tailored to integrate seamlessly with our proposed oxy-fuel engine concept, minimizing any detrimental impact on engine performance. We anticipate that this advanced carbon capture system could achieve up to 100% efficiency, significantly reducing greenhouse gas emissions. We are thrilled to present this groundbreaking oxy-fuel combustion engine concept, which holds immense potential to transform the way we power our world. By combining on-board oxygen generation, efficient carbon capture, and rigorous scientific modeling, we believe this technology has the power to pave the way towards a cleaner, healthier, and more sustainable future.
