Tri Alpha Energy is the world’s largest private fusion company.  Its purpose is to deliver world-changing clean fusion energy technology as fast as possible. Starting with the end in mind, a commercially competitive fusion power plant, the company developed a unique combination of well-understood advanced particle accelerator and plasma physics. The resulting technology is compact, aneutronic, safe, carbon-free and sustainable.

Backed by $500 million in private capital from some of the world’s leading energy and technology investors, the company is well along in validating both the science and engineering integration of this technology. The company’s “money by milestone” venture capital mindset and fast cycle learning capability have driven disciplined, steady progress. While important work remains, Tri Alpha Energy understands the path forward to the first fusion-based commercial power plant.


Tri Alpha Energy’s technology addresses the market demand for new power sources to help mitigate the climate impacts of carbon-based power sources and cost-effectively address the growing global demand for electricity. Today, nuclear fission is the only viable non-CO2 base load commercial power generation technology.  Concerns about cost, safety, and regulatory uncertainty, however, make nuclear fission a challenging choice.  Tri Alpha Energy’s unique approach will intercept market trends by providing a highly cost-competitive, virtually unlimited supply of carbon-free base load electricity offering a safe environmental profile with regulatory predictability.


Tri Alpha Energy utilizes proprietary advanced beam-driven field reversed configuration (FRC) technology to create a superheated plasma environment. Today, this environment is used for technology development. In a future power plant, hydrogen and boron (p-B11) would fuse generating helium and energy. Tri Alpha Energy has taken significant steps toward the engineering integration of the FRC technology and has operated a national lab-scale machine, which in many aspects resembles a future power plant.

Tri Alpha Energy technology applies a fundamentally different approach to addressing the historic challenges that have hampered fusion-based electricity generation – the inability to maintain fuel particles (plasma) “long enough” and at temperatures “hot enough” to validate the path to fusion power.


In June 2015, Tri Alpha Energy demonstrated a significant breakthrough in addressing “long enough,” the most fundamental scientific challenge.  The company delivered sustained plasma performance in its C-2U machine. This milestone is indicative of indefinite plasma life, limited only by the constraints of current hardware and not by underlying physics. We believe this is a first for a compact, commercially competitive fusion technology.


Tri Alpha Energy is now addressing the “hot enough” challenge. Both sophisticated modeling and actual performance data already indicate the Tri Alpha Energy plasma will perform better and better at higher and higher temperatures (“scaling law”). The company is currently investing $200 million to build a new machine (called C-2W) to validate the “hot enough” milestone over the next three to four years.

Tri Alpha Energy also has started to engage with utility and industrial partners to jointly develop a commercialization plan to license its technology. The key aspects of this plan are to determine the regulatory framework and demonstrate technology readiness. Tri Alpha Energy expects to take the first steps toward commercialization over the next decade.


From its earliest days, Tri Alpha Energy has relied on private capital.  This has required a disciplined “money by milestone” venture capital mindset and fast learning approach to deliver milestones tied to technical development and scientific validation.  Based on its track record of performance, Tri Alpha Energy has raised $500 million to date from a diversified group of some of the world’s leading energy and technology investors including New Enterprise Associates (NEA), Venrock, and Wellcome Trust (UK).

The money by milestone approach has been supported by Tri Alpha Energy’s unique fast cycle learning capability that affords it unparalleled speed and agility.  This has enabled Tri Alpha Energy to accelerate performance to meet or beat milestone schedules through rapid experimentation, operational agility and a fast learning culture.  For example, Tri Alpha Energy’s C-2U milestone was delivered with unprecedented speed, requiring just nine months from the start of extensive hardware upgrades to demonstrated results on a national lab-scale device.

Tri Alpha Energy’s rapid experimentation is a particular advantage. A fast path to fusion is intrinsically linked with the ability to run many experiments per day together with an expansive set of diagnostics. The company has performed over 50,000 experiments to date.  Its design of experiments inherently enables exceptionally rapid learning that allows testing of more hypotheses and leads to faster optimization of machine performance. Tri Alpha Energy acquires data from over 60 state of the art diagnostics, and applies sophisticated analytics to its vast data sets to allow quick refinements and identify new directions.


The Tri Alpha Energy team, located in southern California, includes a diverse group of 160 people including leading physicists, engineers and other experts from 25 countries. Tri Alpha Energy’s scientific efforts are guided by an advisory panel of preeminent experts including numerous Nobel Laureates and Maxwell Prize winners.

The board is chaired by Arthur Samberg and includes Steven Specker (Tri Alpha Energy CEO), Ray Rothrock (Venrock), Dick Kramlich (New Enterprise Associates), John Mack (former CEO-Morgan Stanley), Dick Meserve (former Nuclear Regulatory Commission chair, President Emeritus-Carnegie Institution for Science), and Mike Buchanan (Buchanan Investments), among others.


Tri Alpha Energy is determined to deliver clean fusion energy technology that can provide sustainable, commercially competitive base load power and help achieve global energy independence. We are now confident we have sufficient science and engineering understanding to accomplish our goal.
