nT-Tao and Orion Nuclear target 20 MW fusion power for US data centres
Israeli compact fusion company nT-Tao and US advanced nuclear developer Orion Nuclear Energy Corporation have signed a Memorandum of Understanding to identify and develop deployment sites for nT-Tao's Compact Fusion System across the United States. The agreement, announced on 21 September 2026, positions Orion as the US commercialisation partner, responsible for site selection, project financing, offtaker engagement and early regulatory work, while nT-Tao contributes the underlying technology, performance data and deployment expertise.
The collaboration is explicitly targeted at data centres and heavy industrial users that are struggling to secure sufficient grid power. Orion's chairman and chief executive John Aycoth noted that the firm is already developing advanced nuclear projects alongside data centres and industrial loads across six US states, and that customers consistently face the same constraint: they need firm power on-site faster than grid infrastructure can deliver it. The 20 MW output envelope of nT-Tao's system is presented as filling a gap between microreactors, which currently sit in the one-to-ten megawatt range, and utility-scale small modular reactors (SMRs), which typically begin well above fifty megawatts.
Technology status
nT-Tao's Compact Fusion System is based on the company's MEGA (Modular Energy Generator Architecture) pulsed-power platform. The C3 prototype achieved first plasma in January 2026, and in September 2026 nT-Tao deployed a new 50 MW pulsed-power subsystem, described as a five-fold increase in capability, intended to push the prototype toward its next temperature milestone. The company says the system is engineered for manufacturability and a small enough footprint to be sited directly at a customer's facility, rather than requiring a centralised plant.
Oded Gour-Lavie, co-founder and chief executive of nT-Tao, acknowledged that fusion remains a developing technology. "Fusion is still a developing technology, and every milestone matters on the path to commercial reality," he said. "Partnering with a developer like Orion, who knows how to site, permit, and finance real energy projects throughout the US, is exactly the kind of relationship we look for in order to build a credible path from where our technology is today toward commercial deployment."
Neither company disclosed a timeline for commercial readiness, a financing structure, or any named customer or site under evaluation. The MoU commits the parties to working toward identifying a limited number of initial US opportunities for further assessment.
Market and regulatory context
The power constraint facing large-scale compute infrastructure has become one of the most acute near-term bottlenecks in the data centre sector. Hyperscalers and co-location operators are increasingly exploring off-grid or on-site generation to supplement constrained grid connections, with advanced nuclear attracting particular interest given its ability to deliver continuous, high-density output without the intermittency of renewable sources. Several SMR developers, including NuScale (now restructured) and X-energy, are pursuing similar data-centre partnerships, while a number of fusion startups, including Commonwealth Fusion Systems and TAE Technologies, are at varying stages of prototype development.
Regulatory complexity is significant. Any commercial deployment of a fusion device in the United States will require engagement with the Nuclear Regulatory Commission. The NRC published a fusion-specific regulatory framework in 2023 that classifies fusion facilities as "utilisation facilities" under a risk-informed licensing pathway, which is broadly considered more workable than the fission route, though no fusion device has yet completed a full commercial licence process. Orion's existing relationships with utilities and regulators across six states may help accelerate early site-permitting work, but the path from MoU to operational system involves a large number of unresolved technical and regulatory steps.
The collaboration is an early-stage commercial framework agreement. Investors and customers should treat it as a signal of intent rather than evidence of near-term deployment readiness.
