About

Helios is a technology-driven company focused on developing sustainable solutions for life on Earth and in space. The company initially aimed to extract oxygen from lunar minerals and 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. 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. Helios's green steel technology requires less energy and operating costs, and can process abundant low-grade ores and even mining tailings. 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 an imperative.
