Tidal Metals is a deep-tech materials company that extracts decarbonized magnesium directly from seawater and desalination brine using only electricity from renewable sources, without mining, chemical additives, or brine waste. The company's patented process concentrates and extracts magnesium salt to address a critical supply-chain vulnerability: the United States currently produces no primary magnesium while China controls roughly 91% of global supply. Founded by Ph.D. physicists and engineers with backgrounds in nuclear engineering and plasma physics from MIT, Princeton, and Wisconsin-Madison, and backed by DCVC, Tidal Metals aims for carbon-neutral, domestically scalable magnesium production. Surfaced as a portfolio company of DCVC and added to the API Evangelist network; the company publishes no public API, developer portal, or machine-readable surface at this time.
