Scarcity was never the real problem. Concentration was.
Global supply of uranium and critical metals is concentrated in a small number of countries, refined through an even smaller number of facilities. That concentration — not the abundance of the resource — is what drives price volatility and supply risk for utilities, manufacturers, and governments alike.
Seawater holds more uranium than every known terrestrial reserve combined, distributed evenly across every coastline on Earth. Halocline's extraction platforms let any coastal nation become a source, not just a buyer.
We're building the first commercially viable path to that supply — starting from the Gulf Coast, scaling to any ocean.
Three stages. No mine, no tailings, no fixed geography.
Our process moves target minerals from open ocean to sellable product through a sequence designed around cost, not just feasibility.
- 01
Capture
Selective adsorbent arrays are deployed in ocean currents, where they passively bind uranium and target critical metals as seawater flows through — no pumping, no active energy input at the capture stage.
- 02
Concentrate
Loaded material is returned onshore and eluted, reducing volume by several orders of magnitude before it ever reaches a processing facility — the step that makes the economics work.
- 03
Refine
Concentrated material is processed to utility- and industrial-grade product, ready for offtake by nuclear fuel buyers and critical-metal manufacturers.
Energy security is being rewritten. Supply should be too.
Domestic supply
Every coastline is a potential source, reducing dependence on a handful of exporting nations.
No new mines
No overburden, no tailings ponds, no permanent land disturbance — extraction leaves the seafloor as it found it.
Built to scale
Capacity grows by adding arrays, not by opening new deposits — output scales with demand, not geology.
Building the mineral supply chain of the next century.
We're raising to scale our first commercial array from pilot to production off the Gulf Coast. Request our deck for the full technical and commercial case.
