What SuperCritical does

SuperCritical Technologies, Inc. is a privately held, Austin, Texas-based industrial company founded in 2024 that is commercializing seawater extraction of uranium and other critical metals. Its core technology deploys acrylic fibers treated with adsorption chemistries in seawater; the fibers capture dissolved metals via electrostatic charge and are then recovered and processed in an elution bath, with fibers re-treated and re-deployed in an indefinite cycle. The platform is built on an exclusive license to U.S. Government patents developed by American scientists in U.S. Government labs, and the company is positioning its chemistry to address all ~50 elements on the DOE critical list, not only uranium.

The company is currently pre-revenue and pre-production. It is engineering facilities designed to produce millions of pounds of uranium and critical metals annually, with downstream yellowcake processing arranged through a Texas tolling facility. Its go-to-market is direct enterprise engagement with U.S. nuclear power utilities (94 plants generating 20% of U.S. electricity) and U.S. government agencies pursuing supply-chain security under three Executive Orders on nuclear fuels. Pricing is not publicly disclosed and is expected to be quote-based under B2B industrial contracts.

Commercially, SuperCritical competes not with other seawater-extraction firms (none are identified as public peers) but with conventional uranium supply chains, of which 60% is concentrated in Russia, Kazakhstan, and Uzbekistan, while U.S. domestic production remains under 0.5M lbs/year against ~54M lbs/year of reactor demand. The company cites faster permitting versus land-based mining as a structural advantage and is positioning for allied-market export via State Department and EXIM Bank channels. Leadership includes founder/CEO Canon Bryan (previously co-founded Terrestrial Energy, Uranium Energy Corp., and NioCorp Developments), Non-Executive Chairman Neal Froneman (former CEO of Sibanye-Stillwater), and advisors including the former Deputy Director of PNNL's Marine Sciences Laboratory.

Core offering

SuperCritical Technologies extracts uranium (U3O8) and other critical metals from seawater using proprietary acrylic fibers treated with adsorption chemistries. Fibers are deployed in seawater, adsorb target metals via electrostatic charge, and are then processed in an elution bath for metal recovery before being re-treated and re-deployed. The company is engineering facilities designed to produce millions of pounds of uranium and critical metals annually for the domestic nuclear fuel and clean energy supply chain.

Product overview

SuperCritical Technologies is a pioneering company that operates as a single unified technology platform for extracting uranium and critical metals from seawater. The core offering is a proprietary extraction technology that uses acrylic fibers treated with adsorption chemistries to adsorb valuable resources from the ocean. The company is developing engineering programs to design facilities capable of producing millions of pounds annually, with the technology positioned as an environmentally benign alternative to land-based mining. The process involves fiber deployment, adsorption, elution treatment for metal extraction, and fiber re-deployment in an indefinite cycle.

Functional benefit

Products and services

• Seawater Uranium and Critical Metals Extraction Technology Proprietary extraction technology that deploys acrylic fibers treated with adsorption chemistries in seawater; the fibers adsorb uranium and other critical metals via electrostatic charge, are recovered and processed in an elution bath to extract the metals, and are then re-treated and re-deployed indefinitely. Targeted at U.S. nuclear power utilities and government critical-materials programs requiring domestically produced U3O8 and critical metals.
• Uranium (U3O8) and Critical Metals Production Industrial-scale production and sale of uranium (U3O8) and other critical metals recovered from seawater using SuperCritical's proprietary fiber adsorption process, with engineering programs underway to design facilities capable of producing millions of pounds annually and downstream yellowcake processing via a Texas-based tolling facility. Offered to U.S. nuclear power utilities and government agencies for domestic nuclear fuel and clean energy supply.

Expansion highlights6 records

Emerging players

• Terrestrial Energy: Canada-based advanced reactor developer (Nasdaq: IMSR) co-founded by SuperCritical CEO Canon Bryan. It is an emerging player in the nuclear fuel cycle that shares leadership and supply-chain narrative with SuperCritical, representing downstream nuclear demand pull.
• NuScale Power: U.S.-based small modular reactor developer (NYSE: SMR) whose CCO Clayton Scott sits on SuperCritical's board. It represents downstream nuclear demand and the growth thesis underpinning SuperCritical's uranium supply opportunity.

Broad incumbents

• Cameco Corporation: World's largest publicly traded uranium producer, supplying U3O8 and UF6 to the global nuclear fuel cycle. Cameco is the broad incumbent benchmark for uranium production economics and the dominant competitor SuperCritical would need to compete with on cost and reliability.
• Energy Fuels: U.S.-based uranium and rare earth element producer (NYSE American: UUUU) operating conventional uranium mines and a processing mill in Utah. It represents the conventional U.S. uranium-mining incumbent that SuperCritical positions itself against on permitting speed and capital risk.
• Sibanye-Stillwater: Major diversified mining company (JSE: SSW; NYSE: SBSW) led until recently by SuperCritical Chairman Neal Froneman. It is the broad incumbent mining platform whose uranium spin-out experience informs the leadership approach at SuperCritical.
• MP Materials: U.S. rare earth producer and magnetics manufacturer (NYSE: MP) operating Mountain Pass, the largest U.S. rare earth mine. It is a broad incumbent in the domestic critical materials supply security narrative that SuperCritical is also pursuing.
• Kazatomprom: National uranium producer of Kazakhstan and the largest uranium producer in the world, controlling a meaningful share of global U3O8 supply. Kazatomprom represents the low-cost in-situ leach incumbent whose pricing SuperCritical must match or undercut to win share.

Direct peers

• NioCorp Developments: U.S.-based critical minerals developer (Nasdaq: NB) focused on niobium, scandium, titanium, and rare earths, founded by SuperCritical CEO Canon Bryan. It is a directly adjacent critical-metals peer targeting the same DOE critical materials supply security narrative.
• Uranium Energy Corp: U.S.-based uranium producer (NYSE American: UEC), co-founded by SuperCritical's CEO Canon Bryan. It is the most directly comparable peer: a publicly traded domestic uranium mining and production company targeting the same U.S. nuclear fuel supply opportunity.
• ASP Isotopes: U.S.-based isotope and critical materials company (NASDAQ: ASPI) chaired by SuperCritical director Paul Mann. It is a directly comparable peer applying novel enrichment/processing technologies to critical materials with a similar advanced-chemistry profile.
