Helion has commenced construction of a new fusion power facility in Everett, Washington, intended to house its seventh-generation prototype, Polaris. The company states the device is designed to be the first of its kind to demonstrate the ability to produce net electricity from fusion. This development follows a power purchase agreement announced in May 2023 with Microsoft, under which Helion is contracted to supply at least 50 MWe of fusion-generated electricity, with a target operational date of 2028. The new 30,000-square-foot facility is scheduled to become operational in 2024, representing a critical step in the company's roadmap toward commercial power deployment. Source: Helion Energy

Polaris will build upon the results from Helion's previous six prototypes. The company's approach utilizes a pulsed non-ignition fusion system. This method involves heating fuel to temperatures exceeding 100 million degrees Celsius and directly recovering the energy as electricity using a patented high-efficiency generation technology, bypassing the need for conventional steam turbines. The success of Polaris is a prerequisite for fulfilling the commercial agreement with Microsoft and validating the company's direct energy conversion claims. The project is backed by investors including Sam Altman, CEO of OpenAI, who also serves as Helion's chairman. Source: Helion Energy

The success of Polaris is a prerequisite for fulfilling the commercial agreement with Microsoft and validating the company's direct energy conversion claims.

The agreement with Microsoft represents one of the first commercial contracts for fusion energy and sets a firm deadline for the technology's maturation. According to Brad Smith, Microsoft's Vice Chair and President, the partnership supports the company's long-term clean energy goals and aims to advance the market for new, efficient clean energy sources for the grid. For Helion Energy, meeting the 2028 target would signify a major transition from experimental plasma physics to industrial power generation, a milestone the entire private fusion sector is closely watching. The project's progress will serve as a key indicator of the commercial viability of pulsed, non-tokamak fusion concepts. Source: Helion Energy

The construction of the Everett facility and the Polaris device marks a significant capital investment and engineering effort. While the source press release does not specify the total cost or funding allocated for this phase, the physical infrastructure is a tangible commitment to the 2028 delivery timeline. The next key milestones will be the completion of the facility in 2024, followed by the assembly and commissioning of Polaris. Subsequent performance data from Polaris operations, particularly measurements of energy output versus input and system reliability over sustained pulses, will be critical for assessing progress toward the 50 MWe PPA target and the broader potential of Helion's fusion science approach.
