nT-Tao Compact Fusion Power

What nT-Tao Compact Fusion Power does

nT-Tao Compact Fusion Power is an Israel-based, privately-held fusion energy company founded in 2019 that is developing a compact 20 MWe on-site fusion power system branded as the Tao Energy Box. The company's core technology, the Tao Core, is a pulsed compact stellarator that uses high magnetic fields (8-10 Tesla) and high plasma density (approximately 10^22 m^-3) — operating regimes described as impractical for large-scale devices — combined with a proprietary nonlinear control method for plasma stabilization that was peer-reviewed and published in the Actuators journal in December 2025. Systems are designed for modular stacking from 20 MW to gigawatt scale, with the stated goal of delivering distributed, clean, 24/7 baseload power independent of the electrical grid.

The company's primary products and milestones include the C3 prototype (which achieved first plasma in January 2026 within roughly two months of assembly) and the announced Fusion Power Barge (FusPoB) project with the American Bureau of Shipping, targeting a 71.4-meter vessel generating up to 20 MW by 2032. Target customer segments are data centers and AI infrastructure, maritime and ports, national and critical infrastructure (including water, via the April 2026 MOU with Mekorot, Israel's national water company), and EV fleet charging. The business model is pre-revenue, centered on future hardware sales or leasing of Tao Energy Box units, supplemented by potential managed-service and maintenance contracts.

nT-Tao has raised $27 million in disclosed funding to date, comprising a $22 million Series A in February 2023 led by Delek US and NextGear Ventures with participation from Honda, OurCrowd, Mayer Cars & Trucks, and the Grantham Foundation, plus a $5 million Israel Innovation Authority grant in March 2025 (its fourth consecutive IIA grant). The company operates from Hod Hasharon, Israel, with wholly-owned subsidiaries in the United States and United Kingdom, and maintains research collaborations with Princeton University, MIT Plasma Science and Fusion Center, Technion, and Ben-Gurion University of the Negev.

Revenue model

1. Fusion Energy Systems (Hardware Sales): The company plans to generate revenue through sale of Tao Energy Box compact fusion systems. As a pre-revenue company developing first-of-kind fusion technology, the primary revenue model will involve selling or leasing hardware systems to enterprise customers in data centers, maritime, and critical infrastructure sectors. Systems are designed for modular stacking to scale from 20MW to gigawatts.
2. Managed Services and Maintenance: Potential recurring revenue from ongoing maintenance, fuel supply, and operational support services for deployed fusion systems. Given the specialized nature of fusion technology and the Tao Energy Box design emphasizing standardized modules and simplified maintenance, the company may offer service contracts for system upkeep.

Core offering

nT-Tao is developing the Tao Energy Box, a 20 MWe compact on-site fusion power system built around its proprietary Tao Core—a pulsed high-density magnetic confinement stellarator designed for distributed, grid-independent baseload power generation. The system is intended for modular stacking from 20 MW up to gigawatts, enabling deployment in infrastructure-constrained environments such as data centers, maritime vessels, and critical national infrastructure. The company is pre-revenue and operates as a deep-technology engineering organization with active research partnerships with Princeton, MIT PSFC, Technion, and Ben-Gurion University.

Product overview

nT-Tao Compact Fusion Power offers a unified product portfolio centered on the Tao Energy Box, a 20MWe compact on-site fusion power system. At its core is the Tao Core—a proprietary pulsed high-density magnetic confinement generator using stellarator topology with 8-10 Tesla magnetic fields. The system is designed for modular deployment, scalable from 20MW to gigawatts through stacking, targeting data centers, maritime vessels, water infrastructure, and defense applications. The company operates prototype iterations (C3) and has announced the Fusion Power Barge project for floating marine deployment.
