Advancing steel decarbonization
Boston Metal is leveraging the power of electrochemistry to convert all grades of iron ore into high-quality molten metal. Our game-changing platform technology is cost-effective, scalable and creates value throughout the steel value chain.
Molten Oxide Electrolysis (MOE) Steel
Our electrolysis process uses clean, renewable electricity instead of coal to directly convert all grades of iron ore into pure liquid metal. MOE creates a pathway for steel production without CO2 emissions or any need for hydrogen infrastructure, carbon capture or process water, eliminating the complexity and constraints of other multi-step technologies.
Within an MOE Steel cell, an inert anode is immersed in an electrolyte containing iron ore and is electrified. Once the cell reaches 1600 °C, the electrons split the bonds in the iron oxide in the ore, releasing oxygen gas and clean, high-purity liquid metal that can be tapped at the bottom of the cell. No carbon dioxide or other harmful byproducts are generated.
The high-quality molten metal tapped from an MOE cell can be sent directly to ladle metallurgy. As a whole, the MOE Steel process replaces multiple carbon-intensive steps of the traditional steelmaking method: coke production, iron ore sintering and pelletizing, blast furnace reduction and basic oxygen furnace refinement.
MOE cells have already produced liquid iron and ferroalloys
MOE Critical Metals will reach industrial scale in 2026, and we will deploy MOE Steel in the coming years to meet growing global demand for green steel.
We removed carbon from the equation
Our MOE Steel technology replaces fossil fuels with renewable electricity in an efficient, one-step process that has the potential to cut 10% of the world’s carbon emissions.
Key Benefits
Zero CO₂ Emissions
Boston Metal’s MOE Steel is powered by renewable electricity and replaces the most carbon-intensive steps in traditional steelmaking.
Cost Effective
MOE Steel converts all iron grades directly into high-purity molten iron, enabling the broadest possible supply of feedstock in an efficient, cost-competitive and environmentally sustainable process.
Scalable
Modular MOE Steel cells are about the size of a school bus and can scale from thousands to millions of tons of output in two ways: increasing MOE cell production by adding more anodes and increasing MOE plant production by adding more MOE cells.
Revolutionizing Steel Production
Steel is the foundation of our world, but steelmaking is extremely carbon intensive and accounts for about 10% of global CO2 emissions. To reach net-zero carbon emissions, the steel industry needs a direct, scalable solution.
Did You Know?
Our green steel business model is to license our MOE platform technology to steelmakers. Boston Metal will not produce steel. In addition to licensing the technology, we will manufacture and market our metallic inert anodes, which are a critical component of MOE Steel.
The Path Forward
In 2025 we successfully commissioned a multi-inert anode industrial cell that produced tonnage steel, de-risking our technology and validating scalability to achieve commercial production. An MOE Steel demonstration plant will come online in the coming years to meet growing global demand for green steel.
