Decarbonized magnesium from just seawater and electricity
Why we exist
To create a sustainable supply of low-cost, zero-carbon magnesium
Magnesium is the third-most used structural metal in the world — critical to steel and titanium refining, aluminum alloying, transportation, aerospace, and defense. 90% of the global magnesium metal supply currently comes from China, where it’s mined using environmentally destructive and carbon-intensive methods.
We now have an unprecedented opportunity to unlock a vast resource — the world’s lightest structural metal — without digging a single mine or emitting a single ton of CO2. Magnesium from desalination brine is the decarbonized metal of our century.
Considering the auto sector alone, an additional 10 megatons of decarbonized magnesium to replace steel in vehicle manufacturing can reduce carbon emissions by 1 gigaton over the life of those vehicles. Lightweighting mobility is critical to accelerating the global transition toward a lower-carbon future.
Magnesium is the second most abundant metal in seawater, averaging 1.3 kilograms per cubic meter.
