About
Helios is a technology-driven company focused on developing sustainable solutions for life on Earth and in space. Initially aimed at extracting oxygen from lunar minerals, the company developed the Helios Cycle™, a zero-emission process for producing metals. This process significantly reduces energy consumption by using thermal energy to extract iron from ore, emitting only oxygen in the process.
The Helios Cycle™ also applies to other elements such as silicon, copper, and lithium, offering a versatile method for resource extraction that minimizes environmental impact. Helios is positioned as a leader in green steel production and eco-friendly extraction technologies, advancing sustainable practices in the metals industry.
