Helion

At Helion, our engineers design and build machines that must operate with extreme precision: pulsing at nanosecond timescales, surviving enormous forces, all while magnetically coupling cleanly to the plasma itself. Every component of the structure must be designed with reliability, efficiency, and system-level interconnectedness in mind. The result? Bigger, stronger, more efficient magnets and structures that push fusion performance forward. Watch the full video here: https://lnkd.in/eHKgv4uq

The future of energy is pink!

Something really elegant about Helion's approach to fusion is that we directly recover energy from our fusion reactions. This means huge gains for efficiency, bypassing lossy conversion cycles used by most other methods of energy production today. To measure the energy we produce from fusion, we deploy high performance electrical diagnostics throughout our capacitor bank. These diagnostics measure the health of our energy systems and also read back voltages after each pulse. I talk more about how we do that here: https://lnkd.in/gNG9Dfcm

Sat down with Lex Fridman for a wide-ranging conversation about fusion, from the physics behind E=mc² to the engineering challenges of turning fusion pulse energy into electricity. We covered fusion v. fission, geopolitics, simulation and control systems, the energy needs of AI, and what it takes to build the world’s first fusion power plant by 2028. It’s one of the most in-depth discussions I’ve had about where Helion stands today and what it will take to scale. You can watch the full interview here: https://lnkd.in/gbGMRh-B

The first beams are up for Orion, the world’s first fusion power plant!

It’s time to fill up our next fusion factory! This time with more conveyor belts and more automation.     Introducing Omega: our newest production space in Everett, WA.     Just down the road from our headquarters, Antares, Omega is the space where we will expand our capacitor manufacturing capabilities to meet demands for our first fusion power plant and beyond.     Empty now, but not for long, we’ll be outfitting this 165,000+ sq. ft. facility with machines that more than 10x our capacitor throughput over the next year.     Automation engineers – we’re calling you to help us design this space! Check out our open roles and reach out if it’s a fit.  

We’re producing more pulsed power units, each designed to deliver precise high-voltage, high-current discharges. This array of components illustrates the rigor of replication and integration needed to power a high-performing fusion system.

At Helion, we do fusion every day. And we know because we detect neutrons, a fusion product. Read more about the neutron diagnostic suite we have deployed for Polaris in this blog post! https://lnkd.in/g_yfMdkk

Between operations, we recently welcomed GeekWire for an inside look at Polaris, our seventh and final prototype. Polaris has been operating, doing fusion every day for several months. Now, our team continues to focus on improving plasma performance and increasing circuit efficiency across the full system. We’re learning daily and advancing our technology rapidly – all with the goal to bring fusion electricity to the grid as soon as possible.

Now accepting proposals for HERCULES, Helion’s external research funding program! HERCULES will expand Helion’s external development programs to accelerate long-term technical breakthroughs that help scale Helion’s fusion power plants after Orion to global mass deployment. With more than $17 million in funding committed now through 2028, the program supports research labs and universities in developing materials and technologies through three research phases. Proposals will be accepted on a rolling basis, with priority given to submissions received by Jan. 5, 2026. Interested applicants can learn more on this page: helionenergy.com/hercules
