A direct, scalable green steel solution

We’re working to eliminate ~10% of global carbon emissions

We’ve developed a simpler, cleaner alternative to an age-old process


Transforming steel production for a net zero future

We’re commercializing a one-step decarbonization technology that uses clean electricity instead of fossil fuels to produce green steel. Our game-changing technology platform is cost effective, scalable, and creates value throughout the steel value chain.

1
Zero CO₂ Emissions
No coal, coke, or other carbon-intensive fuels

Powered by renewable electricity, Molten Oxide Electrolysis (MOE) converts all iron ore grades into liquid metal and oxygen by separating oxides at high temperatures.

2
Cost Competitive
Capex is a fraction of integrated steelmaking

Compared to traditional production methods, our technology offers a more efficient, lower cost, and environmentally sustainable solution across the steel value chain. It’s competitive without a carbon tax.

3
Modular
Tailormade solution for metals production around the globe

Boston Metal’s modular MOE cells are about the size of a school bus and can be scaled — from thousands to millions of tons of output — simply by adding new cells.


We’re featured in a docuseries inspired by Bill Gates’ book How to Avoid a Climate Disaster

Our Molten Oxide Electrolysis cell is already producing liquid iron

We’re on track to reach commercialization by 2026 to meet growing global demand for green steel.

Our investors

We’re backed by some of the world’s leading cleantech venture capital funds, mining companies, and steel users committed to decarbonizing heavy industries for a net zero future.
