TAE Technologies Raises $150 Million in Latest Funding Round

Latest fundraise supports TAE's efforts to deliver world's first commercial fusion power; Google continues more than 10-year research and funding partnership with TAE

FOOTHILL RANCH, Calif., June 2, 2025 /PRNewswire/ -- TAE Technologies ("TAE"), the leading fusion energy company developing the cleanest and safest approach to commercial fusion power, today announced that it has raised more than $150 million in its latest funding round, exceeding the company's initial target for the round. Chevron Technology Ventures, Google and NEA participated in the round, among other new and existing investors.

TAE has the option to raise additional capital as part of this funding round. With more than $1.3 billion in equity capital raised since inception, this latest fundraise further validates TAE's distinctive approach to commercial fusion.

Michl Binderbauer, CEO of TAE Technologies, said: "Fusion has the potential to transform the energy landscape, providing near-limitless clean power at a time when the world's energy needs are growing exponentially due to the growth of AI and data centers. TAE's technology uses the soundest physics to deliver superior performance in a compact machine, with attractive economics and best-in-class maintainability. We are leading the charge to develop revolutionary fusion technology for full-scale commercial deployment."

Earlier this year, TAE announced a major milestone that fundamentally advances the performance, practicality and reactor-readiness of its proprietary fusion technology. The company's "Norm" breakthrough – achieving stable plasma at over 70 million °C in a simplified fusion device – was made possible in part through TAE's more than decade-long collaboration with Google.

Since 2014, TAE and Google Research have worked together to accelerate fusion science using cutting-edge machine learning. Google engineers worked onsite at TAE facilities to co-develop advanced plasma reconstruction algorithms, leading to significantly improved plasma lifetime and performance. Google's deep integration into TAE's engineering teams helped the company unlock a practical path to economic fusion and was instrumental in enabling the Norm breakthrough that now paves the way for TAE's next milestone: validating net energy capability in its Copernicus reactor. Google's renewed commitment to TAE follows a thorough technical and commercial evaluation of TAE's distinctive fusion approach.

Binderbauer continued: "We're delighted to continue our relationship with Google, who have not only provided funding to TAE but collaborated closely in research and development over many years. With this latest fundraise, we look forward to accelerating our efforts to deliver commercial fusion power."

TAE's fusion systems can provide on-demand, carbon-free, utility-scale power that is also inherently safe. With no risk of meltdown or long-lived radioactive waste, a TAE fusion power plant can be safely placed wherever power is needed. This creates unparalleled flexibility for siting, whether near highly populated areas, remote locations or large-scale data centers.

TAE has been granted more than 1,500 patents worldwide and has successfully constructed five generations of prototypes. Notably, the last four prototypes are comparable in size to traditional natural gas combustion turbines, with two more currently under development.

Additional Information About TAE Technologies

TAE was founded in 1998 to develop commercial fusion power with the cleanest environmental profile. The company has established itself as a leader in an industry that has the potential to transform the energy economy. Notable company and scientific milestones include:

• Raised and deployed $1.2 billion through 11 prior fundraises. Investors include Google, Chevron Technology Ventures, Sumitomo Corporation of Americas, NEA, Wellcome Trust, and the visionary family offices of Addison Fischer, the Samberg Family, Charles Schwab, and others.
• Built five increasingly powerful and productive demonstration units to National Laboratory scale.
• Partnered closely with Google for more than a decade. Among their various achievements together, the companies have co-developed the Optometrist Algorithm, a plasma optimization tool that has helped accelerate TAE's scientific progress.
• Announced in April 2025 the invention of a streamlined approach to form and optimize plasma that increases efficiency, significantly reduces complexity and cost, and accelerates the company's path to net energy and commercial fusion power.
• Advanced construction on its sixth demonstration unit, Copernicus, which is on track to achieve a net energy milestone before the end of the decade.
• Delivered a roadmap for its first prototype power plant, Da Vinci, which will be operational in the early 2030s and will deliver TAE's first commercial fusion power.

Fusion is nature's preferred source of energy. It is the same process that powers the sun and stars, and it is what makes life viable on Earth. When lighter elements fuse under immense heat and pressure, they form new elements and release a tremendous amount of energy. This process is safer than conventional nuclear power because fusion can be stopped at any time - eliminating the risk of a power plant meltdown.

In TAE's future fusion power plant, hydrogen and boron atoms will fuse into three helium atoms inside of a stable, superhot plasma to produce an even more energetic light than the sun – all with no long-lived radioactive waste. When the heat generated by that light warms the walls of the fusion machine, a network of pipes will spring into action to cool the interior walls by collecting that heat into a fluid and ushering it to a steam generator. The steam spins a turbine that then drives an electric generator, similar to what happens in operating power plants today. TAE's unique fusion core supplies a superior and environmentally benign heat source for future power plants.

The essential requirement for capturing net energy across all approaches to fusion is high-quality plasma confinement. TAE has developed a proprietary approach called an advanced beam-driven Field-Reversed Configuration (FRC), which solves the challenge of confinement both from a cost and performance perspective. TAE's approach is the first known design in the world to form an FRC plasma using only neutral particle beams. 

TAE's FRC-based fusion approach is built to integrate with today's grid infrastructure and engineered for cost-effective construction and operation. Unlike other fusion approaches, it has the advantage of being modular, allowing quick and scalable deployment with a much smaller footprint than traditional fusion systems but at similar power outputs. TAE's systems are designed for sustained performance, efficient maintenance and reliable stability, meaning they are adaptable for a wide range of geographies and energy demands.
