TAE Technologies has raised over $150 million in a new funding round backed by Google, Chevron, and NEA, bringing its total equity funding to more than $1.3 billion. The company is developing a compact, hydrogen-boron fusion power system designed to deliver safe, carbon-free electricity. Recent breakthroughs, including stable plasma at 70 million °C, advance its path toward net energy with the Copernicus reactor and eventual commercialization through its Da Vinci prototype.
$150 Million and Counting: TAE Technologies Breaks Its Funding Target
TAE Technologies announced it has raised over $150 million in its most recent funding round, surpassing internal targets. The round included participation from new and existing investors, including Chevron, Google, and NEA. The company also retains the option to raise additional capital as part of this round. This brings TAE’s total equity funding to more than $1.3 billion since its founding in 1998.
The announcement reflects ongoing interest in TAE’s approach to commercial fusion energy, which the company states is the safest and cleanest method under development. The capital will support further development of TAE’s core technologies and accelerate efforts toward achieving net energy from fusion.
Why the World Bets Big on TAE’s Fusion Vision
TAE Technologies is pursuing a unique form of nuclear fusion using hydrogen and boron, aiming to create a reliable, carbon-free, utility-scale power source. The company’s reactors generate power through high-temperature plasma without producing long-lived radioactive waste or carrying the risk of meltdown.
The system is designed to be modular, enabling deployment in various locations including urban centers, remote areas, and high-energy-demand environments such as data centers. TAE’s design emphasizes compactness, maintainability, and operational efficiency while integrating with existing grid infrastructure.
The Power Players: Who’s Fueling TAE’s Clean Energy Drive
The funding round was led by a consortium of influential investors. Google has maintained a strategic research and funding partnership with TAE since 2014. This collaboration has involved on-site integration of Google engineers and the development of machine learning tools for plasma optimization, including advanced reconstruction algorithms.
Chevron continues its support, reflecting its interest in next-generation energy solutions. Other institutional and private investors involved include NEA, Sumitomo Corporation of Americas, the Wellcome Trust, and several family offices such as those of Addison Fischer, the Samberg Family, and Charles Schwab.
From Plasma Breakthroughs to Prototype Reactors: How TAE Gets It Done
In April 2025, TAE announced a significant milestone by achieving stable plasma at over 70 million degrees Celsius in a simplified fusion device. This achievement, called “Norm,” was a product of the company’s ongoing collaboration with Google and marked a critical step toward commercial viability.
To date, TAE has developed five generations of prototype devices, with the last four built to the scale of natural gas combustion turbines. Two additional units are currently under development.
Key developments include:
- Construction of the sixth-generation “Copernicus” reactor, targeting net energy output
- A roadmap to the first prototype power plant “Da Vinci,” projected for the early 2030s
- More than 1,500 global patents related to TAE’s fusion technology

What Sets TAE Apart in the Race for Fusion Energy
TAE’s approach relies on an advanced beam-driven Field-Reversed Configuration (FRC). This method confines plasma using only neutral particle beams, bypassing the complexity and cost issues associated with magnetic confinement techniques seen in other fusion designs.
This architecture is engineered for consistent plasma performance and cost-effective operation. Its modularity allows for scalability while maintaining a small physical footprint. TAE’s focus on machine longevity, simplified maintenance, and compatibility with diverse grid demands differentiates it within the fusion energy sector.
Why This Funding Round Matters for the Future of Global Energy
Global energy consumption is rising, particularly with the proliferation of artificial intelligence and data center infrastructure. TAE positions its fusion power as a solution for reliable and scalable energy delivery.
Its hydrogen-boron fusion method produces helium and light, with no carbon emissions or long-lived nuclear byproducts. Heat generated from the fusion process is transferred to a steam generator, driving turbines in a mechanism similar to current power plants.
This funding round reinforces investor confidence in TAE’s potential to meet long-term global energy demands while supporting decarbonization efforts.
What Comes Next for TAE Technologies and the Fusion Frontier
TAE plans to validate net energy production with its upcoming Copernicus reactor. This milestone will mark a critical step toward the company’s first commercial plant, Da Vinci, scheduled to begin operation in the early 2030s.
Google’s renewed involvement follows a thorough technical and commercial evaluation of TAE’s progress, including their role in developing key machine learning tools like the Optometrist Algorithm.
Future activities will focus on reactor-scale validation, continued AI integration, and preparation for infrastructure-level deployment. With sustained investor support, TAE intends to complete the development and demonstration phases necessary for launching its first commercial fusion facility.
