AMPERA

AMPERA is an advanced nuclear energy company developing compact power solutions for applications with high energy demands, such as AI data centers, defense, and maritime industries. Founded in 2025 by Brian Matthews, a British scientist and entrepreneur with a background in nuclear engineering and additive manufacturing, the company emerged from stealth mode in November 2025. AMPERA is headquartered in Palm Beach Gardens, Florida, in a nearly 100,000-square-foot facility that houses its research, engineering, manufacturing, and administrative operations.

The company's core technology is a subcritical thorium breeder microreactor system. This hybrid fusion-fission architecture is designed to be ultra-safe and operates without producing long-lived nuclear waste or requiring refueling during its operational life. AMPERA utilizes a proprietary TRISO (tristructural isotropic) fuel manufacturing platform, protected by 66 global patents, and employs advanced additive manufacturing to enable scalable production. The reactors are engineered as fully containerized, factory-built modules that can be rapidly deployed on or near customer sites. They are available in two standard configurations: a 15 MWe model for defense and smaller-scale needs, and a 30 MWe commercial version for applications like hyperscale data centers.

AMPERA's business model targets clients facing grid constraints and high demand for continuous, reliable, and emission-free power. The company plans to offer its technology through various commercial models, including power-as-a-service, leasing, and long-term service agreements. In November 2025, AMPERA announced it was backed by an unnamed Fortune 500 global technology leader in AI and data center infrastructure. In June 2025, it was reported that Super Micro Computer acquired an 11% stake for $6 million. More recently, in April 2026, AMPERA entered a strategic collaboration with Scorpio Tankers, a Monaco-based shipping company, to develop and commercialize its microreactors for maritime applications. As part of this partnership, Scorpio Tankers made a $10 million investment in AMPERA. The company has stated its intention to seek licensing from the U.S. Nuclear Regulatory Commission (NRC) for its thorium-fueled reactors and plans to have its reactors at customer locations by 2030.
