Tidal Metals
Tidal Metals is a Trenton/Hamilton, New Jersey deep-tech company that extracts primary magnesium metal from seawater and desalination brine using nothing but renewable electricity and physical processes - no ore mining, no carbon emissions, and no waste stream. Founded by three plasma-physics PhDs who met at the Princeton Plasma Physics Laboratory, the company aims to rebuild a domestic U.S. magnesium supply chain currently dominated by China, serving aerospace, defense, and next-generation automotive manufacturing.
Capture6
Capture6 is a climate-tech company that turns the salty waste brine left over from desalination and water treatment into two things the world needs: fresh water and permanently removed atmospheric CO2. Its integrated platform converts brine into a CO2-absorbing solvent in a single step, eliminating costly brine disposal while producing freshwater, green chemicals, and durable carbon removal. Founded in 2021 and based in the San Francisco Bay Area with operations in New Zealand, the public benefit corporation works with water utilities, industry, and governments across California, Western Australia, New Zealand, and South Korea.
