Helios started its path as a space company, developing technologies that can separate oxygen from metals that will be used on the moon. Any technology designed for space must operate in extreme environments, where sustainability and zero emissions are not an option but a necessity. Out of these necessities, Helios discovered and developed a novel method to produce iron from iron ore, requiring mostly thermal energy, and emitting only oxygen. The Helios team is comprised of professionals in diverse fields, experienced in aerospace and mechanical engineering, electrochemistry and material science.
