On Thursday, October 20, I took a reporting trip to Everett, Wash., to go to Helion Energy, a fusion startup that has raised raised nearly $600 million from a slew of relatively well-known Silicon Valley investors, including Peter Thiel and Sam Altman. It’s got one other $1.7 billion in commitments if it hits certain performance targets.
Because nuclear fusion has the potential to make limitless quantities of unpolluted energy without generating any long-lasting nuclear waste, it’s often called the “holy grail” of unpolluted energy. The holy grail stays elusive, nevertheless, because recreating fusion on earth in a way that generates more energy that’s required to ignite the response and might be sustained for an prolonged time frame has thus far remained unattainable. If we could only manage to commercialize fusion here on earth and at scale, all our energy woes can be solved, fusion proponents say.
Fusion has also been on the horizon for many years, just out of reach, seemingly firmly entrenched in a techno-utopia that exists only in science fiction fantasy novels.

But visiting Helion Energy’s enormous workspace and lab pulled the thought of fusion out of the completely fantastical and into the doubtless real for me. In fact, “potentially real” doesn’t suggest that fusion shall be a commercially viable energy source powering your private home and my computer next 12 months. Nevertheless it not looks like flying a spaceship to Pluto.
As I walked through the huge Helion Energy buildings in Everett, one fully operational and one still under construction, I used to be struck by how workaday every little thing looked. Construction equipment, machinery, power cords, workbenches, and countless spaceship-looking component parts are all over the place. Plans are being executed. Wildly foreign-looking machines are being constructed and tested.

For the workers of Helion Energy, constructing a fusion device is their job. Going to the office day by day means putting part A into Part B and into part C, twiddling with those parts, testing them, after which putting them with more parts, testing those, taking those parts apart possibly when something doesn’t work right, after which putting it back together again until it does. After which moving to Part D and Part E.
The date of my visit is relevant to this story, too, since it added a second layer of strange-becomes-real to my reporting trip.
On October 20, the Seattle Everett region was blanketed in dangerous levels of wildfire smoke. The air quality index for Everett was 254, making it the worst air quality on this planet at the moment, in keeping with IQAir.

“Several wildfires burning within the north Cascades were fueled by warm, dry, and windy weather conditions. Easterly winds flared the fires in addition to drove the resulting smoke westwards towards Everett and the Seattle region,” Christi Chester Schroeder, the Air Quality Science Manager at IQAir North America, told me.
Global warming helps to fuel those fires, Denise L. Mauzerall, a professor of environmental engineering and international affairs at Princeton, told me.
“Climate change has contributed to the high temperatures and dry conditions which have prevailed within the Pacific Northwest this 12 months,” Mauzerall said. “These weather conditions, exacerbated by climate change, have increased the likelihood and severity of the fires that are answerable for the extremely poor air quality.”
It was so bad that Helion had told all of its employees to remain home for the primary time ever. Management deemed it too dangerous to ask them to go away their houses.
The circumstances of my visit arrange an uncomfortable battle. On the one hand, I had a newfound sense of hope about the opportunity of fusion energy. At same time, I used to be wrestling internally with a deep sense of dread in regards to the state of the world.
I wasn’t alone in feeling the load of the moment. “It is vitally unusual,” Chris Pihl, a co-founder and the chief technology officer at Helion, said in regards to the smoke.
Pihl has worked on fusion for nearly 20 years now. He’s seen it evolve from the realm of physicist academics to a field followed closely by reporters and collecting billions in investments. People working on fusion have develop into the cool kids, the underdog heroes. As we collectively blow past any realistic hope of staying throughout the targeted 1.5 degrees of warming and as global energy demand continues to rise, fusion is the house run that sometimes looks like the one solution.
“It’s less of a academic pursuit, an altruistic pursuit, and it’s turning into more of a survival game at this point I believe, with the way in which things are going,” Pihl told me, as we sat within the empty Helion offices looking at a wall of gray smoke. “So it’s mandatory. And I’m glad it’s getting attention.”
How Helion’s technology works
CEO and co-founder David Kirtley walked me across the vast lab space where Helion is working on constructing components for its seventh-generation system, Polaris. Each generation has proven out some combination of the physics and engineering that is required to bring Helion’s specific approach to fusion to fruition. The sixth-generation prototype, Trenta, was accomplished in 2020 and proved capable of reach 100 million degrees Celsius, a key milestone for proving out Helion’s approach.
Polaris is supposed to prove, amongst other things, that it may well achieve net electricity — that’s, to generate greater than it consumes — and it’s already begun designing its eighth generation system, which shall be its first business grade system. The goal is to reveal Helion could make electricity from fusion by 2024 and to have power on the grid by the tip of the last decade, Kirtley told me.

A number of the feasibility of getting fusion energy to the electricity grid in america is dependent upon aspects Helion cannot control — establishing regulatory processes with the Nuclear Regulatory Commission, and licensing processes to get required grid interconnect approvals, a process which Kirtley has been told can range from a number of years to as much as ten years. Because there are such a lot of regulatory hurdles mandatory to get fusion hooked into the grid, Kirtley said he expects their first paying customers are prone to be private customers, like technology firms which have power hungry data centers, for instance. Working with utility firms will take longer.
One a part of the Polaris system that appears perhaps probably the most otherworldly for a non fusion expert (like me) the Polaris Injector Test, which is how the fuel for the fusion reactor will get into the device.
Arguably the best-known fusion method involves a tokamak, a donut-shaped device that uses super powerful magnets to carry the plasma where the fusion response can occur. A world collaborative fusion project, called ITER (“the way in which” in Latin), is constructing a large tokamak in Southern France to prove the viability of fusion.
Helion shouldn’t be constructing a tokamak. It’s constructing an extended narrow device called a Field Reversed Configuration, or FRC, and the following version shall be about 60 feet long.
The fuel is injected briefly tiny bursts at each ends of the device and an electrical current flowing in a loop confines the plasma. The magnets fire sequentially in pulses, sending the plasmas at each ends shooting towards one another at a velocity greater than a million miles per hour. The plasmas smash into one another within the central fusion chamber where they merge to develop into a superhot dense plasma that reaches 100 million degrees Celsius. That is where fusion occurs, generating latest energy. The magnetic coils that facilitate the plasma compression also get well the energy that’s generated. A few of that energy is recycled and used to recharge the capacitors that originally powered the response. The extra extra energy is electricity that might be used.
That is the Polaris Injector Test, where Helion Energy is constructing a component piece of the seventh generation fusion machine. There shall be one among these on both sides of the fusion device and that is where the fuel will get into the machine.

Kirtley compares the pulsing of their fusion machine to a piston.
“You compress your fuel, it burns extremely popular and really intensely, but just for a bit bit. And the quantity of warmth released in that little pulse is greater than a big bonfire that is on on a regular basis,” he told me. “And since it is a pulse, since it’s only one little high intensity pulse, you’ll be able to make those engines way more compact, much smaller,” which is essential for keeping costs down.
The thought is definitely not latest. It was theorized within the Fifties and 60s, Kirtley said. Nevertheless it was impossible to execute until modern transistors and semiconductors were developed. Each Pihl and Kirtley checked out fusion earlier of their careers and weren’t convinced it was economically viable until they got here to this FRC design.
One other moat to cross: This design does use a fuel that could be very rare. The fuel for Helion’s approach is deuterium, an isotope of hydrogen that’s fairly easy to seek out, and helium three, which is a really rare form of helium with one extra neutron.
“We used to need to say that you simply had to enter outer space to get helium three since it was so rare,” Kritley said. To enable their fusion machine to be scaled up, Helion can be developing a approach to make helium three with fusion.
A dose of hope
There is no such thing as a query that Helion has a whole lot of steps and processes and regulatory hurdles before it may well bring unlimited clean energy to the world, because it goals to do. But the way in which it feels to walk around an unlimited wide-open lab facility — with a few of the largest ceiling fans I even have ever seen — it seems possible in a way that I hadn’t ever felt before. Walking back out into the smoke that day, I used to be so grateful to have that dose of hope.
But most individuals weren’t touring the Helion Energy lab on that day. Most individuals were sitting stuck inside, or putting themselves in danger outside, unable to see the horizon, unable to see a future where constructing a fusion machine is a job that’s being executed like a mechanic working in a garage. I asked Kirtley in regards to the battling feeling I had of despair on the smoke and hope on the fusion parts being assembled.
“The cognitive dissonance of sometimes what we see out on this planet, and what we get to construct here is pretty extreme,” Kirtley said.
“Twenty years ago, we were less optimistic about fusion.” But now, his eyes glow as he walks me across the lab. “I get very excited. I get very — you’ll be able to tell — I get very energized.”
Other young scientists are also enthusiastic about fusion too. At the start of the week once I visited, Kirtley was on the American Physics Society Department of Plasma Physics conference giving a chat.
“At the tip of my talk, I walked out and there have been 30 or 40 people who got here with me, and within the hallway, we just talked for an hour and a half in regards to the industry,” he said. “The joy was huge. And a whole lot of it was with younger engineers and scientists which can be either grad students or postdocs, or in the primary 10 years of their profession, which can be really enthusiastic about what private industry is doing.”
