Helios

WE ARE HELIOS

Decarbonizing the steel industry,
zero direct emissions at no extra cost

Helios began as a space technology company with the bold mission to extract oxygen from the moon. Faced with a severe and unforgiving lunar environment, our research team was pushed to achieve unprecedented innovation. Our challenge was to enable the separation of oxygen from lunar minerals in extreme environments, where zero emissions are not an option but a necessity.

Our efforts resulted in a breakthrough zero-emission method for metal production, applicable both in space and on Earth. This process, known as the Helios cycle™, produces iron from iron ore, using mostly thermal energy, while emitting only oxygen. It requires significantly less energy than traditional methods, dramatically cutting costs and minimizing environmental impact.

From our initial “Moonshot,” we have evolved into a leader in green steel innovation, poised to transform the trillion-dollar steel industry. Through strategic partnerships and collaborations, we are scaling our operations and advancing our ambitious vision, on Earth and beyond.

Our StoryRespecting the Source 
Helios is a technology-based company that is committed enable positive impact on the environment and mankind. Each step along the way is paved with a deep sense of respect and responsibility, guided by human integrity and intelligence – and a commitment to a better future for ourselves and for the next generations to come. 
Our MissionLeveraging the power of novel technology and our passion for humanity to ensure viable and sustainable life on earth and beyond.
We vision Securing the Elements of the Future
Helios has set out to empower humanity to reduce its impact on the planet by optimizing resource utilization on earth - and beyond. 

This is us

We are all part of a leading team

We are a team of researchers, scientists, and materials experts. Nearly one-quarter of the company holds a PhD and nearly half of the company are women. We were the first technology innovator ever to become a member of the World Steel Association. We are quickly growing and looking for passionate, entrepreneurially-minded people to join us.

Ironmaking is rooted in 500-year-old technology and 3,000-year-old chemistry. Innovation in this sector tends to be incremental due to the industry’s conservative and risk-averse nature. The sodium-based process, known as the Helios Cycle™, was originally developed for lunar oxygen production. Thus, it not only represents thinking outside the box, but it literally comes from the moon.

Producing green steel with hydrogen requires green hydrogen, which involves significant energy and operational costs, far exceeding those of current ironmaking processes. The economic viability of hydrogen-based green steel depends heavily on external taxes or subsidies. While this might be feasible in niche cases or in specific countries like Sweden, this approach is not scalable for the global steel industry.

Yes, demonstrating our technology on the lunar surface is a crucial milestone as part of our long-term vision to utilize resources beyond Earth. We expect our first mission to the Moon to take place in 2028.

At every stage, we collaborate with leading experts and regulatory authorities to ensure we meet all safety and environmental compliance standards.

The Helios Cycle stands out for its ability to produce substantial volumes of iron in a relatively compact setup, outperforming both existing and developing technologies. This allows for quicker market penetration, as our full-scale furnaces will be significantly smaller than alternatives, enabling faster and more efficient scaling to meet global demand.

We collaborate with leading financial firms, strategic partners, and government agencies, all of whom support us in achieving our goals and long-term vision.

Our pilot plant is scheduled for 2026, with our first commercial units expected to be available by 2028.

The operational costs of the Helios Cycle are projected to be 30% lower than current polluting technologies. Beyond the superior unit economics, the significant reduction in carbon emissions alone could save the steel industry over $200 billion.
