What Ampera does
Ampera, Inc. is a U.S.-based clean energy company founded in 2025 that designs and develops subcritical thorium-based microreactor systems intended to deliver 15 to 30 MWe of continuous, emission-free power for thirty years without refueling. Its core technology is a fusion-fission hybrid architecture combining an integrated neutron driver with TRISO thorium fuel, a spherical monolithic reactor core, passive walk-away safety, and supercritical CO2 power conversion in a sealed, factory-built, containerized form factor. The product portfolio includes the Genesis (15 MWe) and Nexus (30 MWe) units, the Integrated Energy Architecture platform combining waste heat recovery with advanced nuclear, and a Command Center for remote monitoring and control of deployed assets. The company reports a portfolio of more than 60 patents covering proprietary TRISO fuel manufacturing methods including liquid jetting and additive manufacturing, and it vertically integrates the fuel value chain through Ampera Australia Pty Ltd for thorium procurement.
Ampera serves enterprise customers in three primary verticals: AI infrastructure and hyperscale data centers seeking sovereign, grid-independent power for compute workloads; defense organizations requiring long-duration, supply-chain-independent energy for installations and naval vessels; and commercial maritime operators, including a strategic collaboration with Scorpio Tankers targeting floating nuclear power barges and nuclear-powered vessels across an addressable market of more than 10,000 commercial ships. The commercial model is a turnkey Power-as-a-Service leasing structure under which AMPERA retains ownership and remote operational control of each unit over a 30-year lifespan, with customer deployments scheduled to begin before end of 2027. Strategic investors include Super Micro Computer (11% equity) and Scorpio Tankers, alongside a $20 million SEC exempt offering.

Revenue model
- Microreactor Leasing / Power-as-a-Service: Units are leased to customers and operated remotely by AMPERA for a 30-year lifespan. This turnkey model provides customers with emission-free power without capital expenditure or operational complexity, with AMPERA retaining ownership and operational control of the nuclear systems.
- Power Generation Contracts: Direct power purchase agreements with data center, defense, and maritime operators. Initial systems targeting up to 30 MWe per unit with customer deployments planned before end of 2027.
- Maritime Nuclear Power Solutions: Co-development and deployment of floating nuclear power barges and nuclear-powered commercial vessels in partnership with Scorpio Tankers. Revenue generated through power supply contracts and potentially vessel-based deployments.

Ampera competitors and assessment
Company assessmentDirect peers
- NuScale Power: NuScale is the most advanced U.S. SMR developer, commercializing light-water small modular reactors for utility and data center customers. Both NuScale and Ampera target the same AI/data center power gap with modular nuclear designs under NRC review, making NuScale the most direct comparable in product category, customer base, and regulatory pathway.
- Oklo: Oklo is developing the Aurora microreactor - a compact, factory-built fast fission system targeting data center customers under a power-purchase model. Oklo and Ampera are direct peers in microreactor product category, target market (hyperscalers/data centers), and Power-as-a-Service business model.
- Radiant Nuclear: Radiant is developing a portable, factory-built gas-cooled microreactor (Kaleidos) specifically aimed at data centers and remote industrial sites. Highly comparable to Ampera as a microreactor developer targeting the same data center vertical with a sealed-core factory-financed delivery model.
- TerraPower: TerraPower (Bill Gates-backed) is developing the Natrium sodium-cooled fast reactor and traveling wave reactor designs for advanced nuclear power. Both companies target advanced reactor commercialization under new NRC frameworks, with comparable capital intensity, long development timelines, and corporate strategic investor profiles.
- X-energy: X-energy is developing the Xe-100 high-temperature gas-cooled reactor (HTGR) using TRISO fuel, targeting industrial process heat and electricity. Comparable to Ampera as an advanced Gen IV reactor developer using TRISO fuel, with similar regulatory pathway under advanced reactor frameworks.
- Last Energy: Last Energy is developing small modular PWR microreactors targeting European industrial and data center customers under a power-purchase business model. Directly comparable in scale (sub-50 MWe), factory-built factory-financed deployment model, and target customer base of energy-intensive commercial sites.
- Core Power: Core Power is developing floating molten salt reactor-based marine nuclear power systems for commercial shipping. The closest direct peer to Ampera's maritime nuclear strategy with Scorpio Tankers, sharing both the marine target market and the floating barge deployment concept.
- Kairos Power: Kairos Power is developing the fluoride salt-cooled high-temperature reactor (FHR) with TRISO fuel under an iterative NRC licensing approach. Comparable as a Gen IV advanced reactor developer using TRISO fuel and pursuing non-LWR pathways under NRC's advanced reactor frameworks.
Broad incumbents
- Westinghouse Electric Company: Westinghouse is an established nuclear OEM now developing the eVinci microreactor alongside its large AP1000 reactor business. A broad incumbent in nuclear power generation equipment with overlapping microreactor ambitions, but operating from a much larger portfolio and incumbent market position.
- BWX Technologies: BWXT is developing the BANR microreactor for the U.S. Department of Defense and commercial customers. Comparable as a microreactor developer with strong defense ties and NRC engagement, though BWXT is a much larger incumbent serving naval nuclear propulsion and government markets broadly.
