Fuse Energy Technologies

Fuse Energy Technologies Corporation, commonly known as Fuse, is a privately held U.S. technology company working at the intersection of fusion power, pulsed-power engineering, radiation testing, and national security. The company was founded in 2019 by J.C. Btaiche, who established it at the age of 19 to investigate possible approaches to fusion energy. Fuse eventually selected a magneto-inertial fusion architecture based on a MagLIF Z-pinch device, supported by an advanced pulsed-power driver. Rather than treating commercial fusion generation as its only development path, Fuse has built a business model around radiation and nuclear-effects testing. Its systems are intended to expose government and commercial hardware to short, powerful bursts of radiation so that customers can evaluate the resilience of electronics, infrastructure, and other equipment. This defense-oriented work provides an applied testing and engineering program alongside the company’s longer-term effort to develop a fusion generator capable of producing clean energy. Fuse operates a radiation facility at its headquarters in San Leandro, California. The facility has been described as supporting testing for national-security customers and has received media attention for its unusual combination of high-energy radiation equipment and fusion research. The company has held contracts with the United States Air Force and the National Nuclear Security Administration. It has also entered cooperative research and development agreements with Sandia National Laboratories and Los Alamos National Laboratory. A major technical step came in 2024, when Fuse conducted a six-stage live-fire test of TITAN, described by the company as the first high-energy, high-power impedance-matched Marx generator. The machine is intended to function as the pulsed-power driver for future Fuse fusion systems. Experimental results from TITAN were published in Scientific Reports in July 2024, providing a public account of the company’s pulsed-power work. Fuse announced two additional fusion platforms in 2024. Z-Star is intended as a test platform, while Apeiron I is described as a pilot fusion plant. These projects indicate a staged development strategy: establish experimental and testing capabilities, validate the pulsed-power architecture, and then apply that technology to a pilot-scale fusion system. The company has recruited personnel with experience in government, nuclear security, national laboratories, intelligence, and nuclear engineering. Lisa Gordon-Hagerty, a former National Nuclear Security Administrator and former U.S. Department of Energy Under Secretary, joined Fuse’s board in 2024. James Owen, formerly chief engineer at Los Alamos National Laboratory, serves as president of Fuse Federal, LLC, the company’s federal subsidiary. Laura Thomas, a former Central Intelligence Agency base chief in Afghanistan, is chief strategy officer, and Vahid Damideh, formerly associated with the Atomic Energy Organization of Iran, serves as chief engineer. Fuse’s investors include Bracket Capital, Tamarack Global, and Buckley Ventures. Public reporting in September 2024 described the company as having a valuation exceeding $200 million, although the company’s private status means that detailed financial information is not publicly available in the cited reference material. Fuse remains an active development-stage company whose commercial prospects depend on the performance, scalability, regulatory treatment, and economics of its radiation-testing and fusion technologies.

Fuse Energy Technologies Corporation was founded in 2019 by J.C. Btaiche, who began the company at the age of 19 to evaluate different approaches to fusion power. After considering alternative fusion concepts, Fuse chose to pursue a magneto-inertial fusion design based on a MagLIF Z-pinch device. The selected approach requires a powerful pulsed-power system capable of rapidly delivering energy to the fusion apparatus. The company developed this pulsed-power capability as part of a broader dual-use strategy. In addition to serving as a potential driver for future fusion generators, high-energy pulsed-power equipment can support radiation and nuclear-effects testing. Fuse therefore established a radiation-testing business aimed at government and commercial customers seeking to assess the resilience of hardware under intense radiation bursts. This work created a near-term defense and national-security application while the company continued its longer-term fusion program. Fuse established its headquarters and radiation facility in San Leandro, California. Its work attracted interest from U.S. national-security institutions, and the company entered into contracts with the United States Air Force and the National Nuclear Security Administration. Fuse also formed cooperative research and development relationships with Sandia National Laboratories and Los Alamos National Laboratory. In February 2024, the United States Air Force awarded Fuse a contract concerning new options for nuclear-effects testing. During the same year, the company carried out a six-stage live-fire test of TITAN, an impedance-matched Marx generator described as a high-energy, high-power machine. TITAN is intended to be the pulsed-power driver for Fuse’s future fusion generators. The company’s experimental results from the machine were published in Scientific Reports in July 2024. Fuse expanded its stated fusion roadmap in 2024 by announcing two additional platforms. Z-Star was presented as a test platform for fusion development, while Apeiron I was presented as a pilot fusion plant. The platforms form part of a staged program linking laboratory testing, pulsed-power development, and eventual pilot-scale energy generation. The company also strengthened its leadership and governance with personnel from government and national laboratories. Lisa Gordon-Hagerty, who previously served as National Nuclear Security Administrator and as an Under Secretary at the U.S. Department of Energy, joined the board in 2024. James Owen, a former chief engineer at Los Alamos National Laboratory, became president of Fuse Federal, LLC. Laura Thomas, a former CIA base chief in Afghanistan, became chief strategy officer, and Vahid Damideh, formerly an atomic-energy researcher in Iran, became chief engineer. Fuse has received investment from Bracket Capital, Tamarack Global, and Buckley Ventures. A September 2024 Bloomberg report described the company’s valuation as more than $200 million, but Fuse is privately held and the available reference material does not provide a full financial history. The company remains focused on defense testing and fusion technology development, with the commercial realization of its energy systems still dependent on technical validation, scale-up, and regulatory and market conditions.
