In this talk I am going to highlight some aspects regarding the transformation of CO2 to useful products (e.g., oxygen and hydrocarbons) in the space (and specifically on the International Space Station and Mars). Considering the composition of the Martian atmosphere (96% CO2), the most important source of oxygen and any carbon-based chemicals (fuels, food, etc.) is CO2. Sunlight is available (with a significant of UV-component), therefore solar panels can provide electricity, or sunlight can even be directly used in photocatalytic or photoelectrochemical cells. My talk will present the already existing technologies and discuss the potential and the intrinsic limitations of novel approaches. Specifically, I will discuss our recently developed ultralightweight electrochemical cell, together with the micro/nano-engineered membrane electrode assembly, which enables the operation of the electrolyzer in a microgravity environment.
