About the project
This project will focus on using non-thermal plasma technology to convert CO2 on Mars into oxygen. We aim to push the boundaries of space exploration. Our goal is to develop a novel, compact in-situ resource utilisation (ISRU) system that could revolutionise resource generation for future space missions.
Water, oxygen, and fuel are essential for sustaining astronaut life and ensuring a safe return journey to Earth during future human missions to Mars. Because a typical Mars mission lasts 21 months, carrying all the necessary supplies is impractical, and resupply missions are extremely costly.
The most viable solution for long-duration crewed missions is in-situ resource utilisation (ISRU), which enables the production of vital resources like oxygen directly from the Martian atmosphere. By minimising the transport of water, oxygen, and fuel from Earth, Mars exploration becomes more affordable, and more scientific equipment can be carried, facilitating unprecedented discoveries.
Unlike traditional methods like solid oxide electrolysis (SOE), which require high operational temperatures, non-thermal plasma processes can operate at lower temperatures and energy costs. This is achieved through direct electron impact and the transfer of electron energy into vibrational excitation, making plasma-based ISRU a key technology for sustaining human missions and long-term occupation on Mars. Additionally, this technology has potential applications in Lunar exploration.
You will explore how metal catalysis affects plasma chemistry and CO2 dissociation, seeking to understand the underlying mechanisms that drive plasma-based CO2 conversion. The project involves simulating plasma chemistry and reactor dynamics in detail, as well as experimentally testing various plasma reactor configurations. By examining different electrode geometries and catalytic materials, You will assess their effect on CO2 conversion efficiency and overall plasma chemistry.
This project builds on previous work, including an all-in-one ISRU system supported by the UK Space Agency and ESA-funded projects on non-thermal plasma technology.
You'll join a world-leading research group at the forefront of plasma and space propulsion technologies. You'll gain valuable experience in both the theoretical and experimental sides of plasma research, and learn from industry partners and peers about the wider challenges in aerospace engineering.
