Overview
Project Omega is a Newport, Rhode Island-based advanced nuclear company founded by chemist and serial entrepreneur Dr. Stafford ("Staff") Sheehan, formerly co-founder of Air Company.
On November 9, 2026, a company-issued Business Wire release announced an $80 million Series A led by B Capital, with noa VC and 645 Ventures participating, alongside returning investors Starship Ventures, Mantis Ventures, Decisive Point, Virta Ventures, Pace Ventures, Essential Capital and Washington Harbour Partners. Jeff Johnson of B Capital is joining the board.
The company did not disclose a valuation, share pricing, ownership changes or an exact legal closing date distinct from the release. A separate $12 million seed financing was announced on February 11, 2026, led by Starship Ventures, with Mantis Ventures, Buckley Ventures, Decisive Point and Slow Ventures among participants. The two independently disclosed equity rounds total $92 million.
Do not add government programme award values or announced facility investments to this equity total.
Product and buyer reality: the company is pursuing two related but differently mature activities. Its proposed commercial pyroprocessing refinery would recover useful feedstocks from stored used nuclear fuel rather than sell grid electricity.
Downstream products may include radioisotope power cells for persistent sensing and other remote missions, materials for advanced-reactor fuels, and specialized isotopes for industrial or medical uses.
In a proposed government or industrial buyer journey (illustrative, not a deployed customer transaction), a defense or remote-operations integrator identifies an off-grid power requirement; specifies electrical load, mission lifetime, environment and containment/security conditions; evaluates Omega's modular X Series hybrid systems and planned isotope-powered options; undertakes engineering qualification and regulatory safety review; then integrates and monitors a certified power product if qualification succeeds.
Public pricing, signed long-term offtake agreements, delivery volumes and gross margins were not found.
The physics and maturity must not be collapsed. A radiovoltaic cell converts energy from radioactive decay directly to electrical current; it is not a fission reactor, nor is it conventional ten-hour grid battery storage. Omega says PNNL demonstrated stable electrical current from strontium-90 and that the team has worked with Idaho National Laboratory through ARPA-E's CURIE program.
The June 2026 $3.37M DARPA Rads to Watts award was to a Morgan State-led consortium involving Northrop Grumman, PNNL and Omega; it is NOT a $3.37M equity investment or necessarily the amount earned by Omega. The American Nuclear Society's July account describes DARPA teams working toward unit-cell demonstrations and potential scaled arrays, not an Omega commercial nuclear-battery production line.
Omega's X Series modular hybrid product is in development and initially combines conventional storage/generators/renewables, with isotope power intended for future integration.
As of November 9, 2026, Omega said it intended to begin construction of a nuclear fuel recycling facility. That is a future project, not evidence of a licensed or operating commercial refinery. Its release claims a potential reduction in nuclear waste volume of up to 90%; this is an issuer claim, not verified commercial throughput, mass balance or elimination of long-lived waste hazards.
Commercial receipt, processing, transportation, containment and disposition of radioactive materials involve licensing and safeguards review; the US NRC describes separate obligations for fuel-cycle facilities and radioactive material possession. The company has not disclosed a complete commercial licensing schedule or fully allocated per-kilogram recycling costs.
The US spent-fuel stockpile is an inventory of materials held at various sites, not automatically company-owned free feedstock or immediately available for sale.
Competitive alternatives differ by use case: Orano operates established aqueous reprocessing internationally; Oklo and Curio Solutions have nuclear fuel-recycling initiatives; Zeno Power and conventional primary batteries/solar-generator systems may address off-grid power requirements with different serviceability and licensing tradeoffs. These are not all head-to-head equivalents.
Commercialization depends on reliable isotope recovery, radiation-tolerant power conversion, specific power output, system qualification, regulatory permits, spent-fuel access contracts and customer demand.

Why Project Omega is interesting
Its November 9, 2026 $80M Series A finances a proposed nuclear recycling pilot and persistent-power systems; commercial fuel recycling, radioisotope mass production and licensed deployments are not yet proven. The investment follows a separately announced $12M February seed.
Product & use cases
Illustrative five-stage defense/remote-operations procurement path, not a tested product: (1) define an off-grid mission's power budget, maintenance interval and radiation safety constraints; (2) evaluate the X Series modular hybrid power architecture and planned radiovoltaic sources; (3) compare generator/solar/battery replenishment against future isotope-source lifetime and cost; (4) test physical integration and obtain mission-specific regulatory, shielding and safety approvals; (5) qualify deployment, servicing and end-of-life handling. No public per-unit pricing or mass-produced radioisotope product established. The separate planned pyroprocessing facility would provide feedstock, if constructed, permitted and operational.
- Long-duration power for remote, inaccessible defense and maritime sensors where batteries or fuel resupply are costly.
- Future space and undersea radioisotope-powered systems requiring long maintenance intervals.
- Potential recovery of advanced reactor feedstock and selected medical or industrial isotopes from used nuclear fuel.
- Hybrid modular off-grid power using existing generation and storage components while isotope integration is developed.
Key facts
- $80M Series A company-announced November 9, 2026, led by B Capital; valuation not disclosed.
- $12M separate seed disclosed February 11, 2026, led by Starship Ventures; $92M sum of identified equity rounds.
- PNNL electricity-current demonstration is an early technical result; no verified commercial nuclear refinery or mass-produced radiovoltaic device.
- Planned X Series hybrid expeditionary products initially use conventional power; isotope integration is future work.
- DARPA's $3.37M award went to a multi-party Morgan State-led team, not a Project Omega equity financing.

Competitive landscape
Edge: Proposed vertical integration of recycling and radioisotope power could help source domestic isotopes and reduce dependence on external supply chains. Distinctiveness is a strategic hypothesis, not a proven manufacturing moat: scale economics, licensing, supply agreements, product power density, reliability and customers are still to be validated.
-
Orano incumbent
Established commercial nuclear recycling using different aqueous processes; not focused primarily on Omega's expeditionary battery use cases.
-
Curio Solutions adjacent
US advanced fuel recycling and materials recovery; scale and regulatory status require separate checks.
-
Oklo adjacent
Advanced nuclear power and fuel-cycle initiatives, different commercialization and reactor business model.
-
Zeno Power adjacent
Radioisotope energy systems for remote and strategic environments; compare isotope pathways and end-product qualification.
-
Conventional batteries, solar and generators alternative
Commercially available off-grid power with predictable service regimes; may require refueling/replacement but avoids radioisotope handling.
