Helion Energy aims to operate the world's first commercial nuclear fusion power plant by 2028 [1].
This goal represents a significant acceleration in the timeline for fusion energy, which has long been viewed as a distant prospect. If successful, the technology could provide a near-limitless source of carbon-free electricity, fundamentally altering the global energy landscape and the trajectory of climate change.
David Kirtley, CEO of the Redmond, Washington-based startup [3], discussed the company's plasma-physics approach during a recent appearance on the Lex Fridman Podcast. Kirtley said that Helion utilizes a pulsed-magnetic approach to achieve fusion, which he describes as the fastest path to commercial viability [4].
The company's prototype reactor has already achieved plasma temperatures of approximately 270 million degrees Fahrenheit [2]. This heat is necessary to force atomic nuclei together, mimicking the process that powers the sun. Kirtley said that mastering this process is the key to solving climate change.
While some industry reports suggest a timeline extending into the early 2030s, Kirtley maintains the 2028 target [1]. He said that Helion's specific method of fusion is the most promising path to practical application [5]. The company's focus remains on creating a system that can be scaled for industrial power generation rather than purely theoretical research.
"Fusion is the ultimate clean-energy source — if we can master it, we solve climate change," Kirtley said [6].
The Redmond facility serves as the hub for this development, where engineers work to refine the magnetic compression required to sustain the fusion reaction. The company believes its approach avoids some of the complexities associated with traditional tokamak reactors, allowing for a more compact and efficient design.
“We’re on track to have a commercial fusion power plant by 2028.”
The pursuit of commercial fusion by 2028 places Helion Energy in a high-stakes race against both government-funded projects and other private ventures. While achieving temperatures of 270 million degrees Fahrenheit proves the physics of the reaction, the transition to a commercial power plant requires solving immense engineering challenges regarding energy net gain and material durability. A successful rollout would decouple energy production from carbon emissions and resource scarcity.
