Boston Metal - 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 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 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.
Zero CO2 Emissions
Boston Metal’s MOE is powered by renewable electricity and replaces the most carbon-intensive steps in traditional steelmaking.
Cost Effective
MOE 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 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.
