Fusion to the grid: CFS and Helion leaders on breakthroughs at TechCrunch Disrupt 2026. Tl;dr. * Commonwealth Fusion Systems co-founder Brandon Sorbom and Helion Energy CEO David Kirtley will headline a fusion energy session on the Smart Systems Stage at TechCrunch Disrupt 2026 in San Francisco. * The discussion will focus on recent technical breakthroughs at SPARC and Polaris, plus the path to first grid-connected fusion power plants in Virginia and Washington. * Expect a candid debate on timelines, capital costs, and what it will actually take to scale fusion from scientific demonstration to commercial grid power. Two different roads to the same star. Fusion has spent decades as the energy source of the future. At TechCrunch Disrupt 2026, TechCrunch is betting that future is finally close enough to put on stage. The Smart Systems Stage session will pair two of the most closely watched leaders in private fusion: Brandon Sorbom, co-founder and Chief Science Officer of Commonwealth Fusion Systems (CFS), and David Kirtley, co-founder and CEO of Helion Energy. Together they represent more than $3 billion in private investment and the two most advanced, and most divergent, approaches to commercial fusion in the U.S. CFS is pursuing the tokamak path with high-temperature superconducting magnets, building its SPARC demonstration machine in Devens, Massachusetts. Helion is taking a very different bet with its pulsed field-reversed configuration system and direct electricity recovery, now testing at its Everett, Washington facility with its Polaris prototype and building its first commercial plant, Orion. Why Disrupt, why now. The timing is no accident. TechCrunch Disrupt 2026, set for October 13-15 at Moscone West in San Francisco, comes at an inflection point for fusion. In the last 18 months, the industry has shifted from physics milestones to power-plant execution. CFS completed its massive magnet manufacturing run, delivered key SPARC tokamak components, and broke ground with Dominion Energy on planning for its first ARC-class commercial plant in Chesterfield County, Virginia, targeting 400 MW to the grid in the early 2030s. Helion, meanwhile, has hit high-power pulsed operation milestones on Polaris, its seventh-generation prototype, signed expanded power purchase agreements including its landmark Microsoft deal for 50 MW and industrial partnerships for data centers and steel, and started construction on its Orion plant in Malaga, Washington with Chelan County PUD for grid interconnection. Add in surging AI data center demand, new DOE milestone funding, and NRC regulatory progress on fusion-specific licensing, and fusion has moved from science panel to infrastructure conversation. That is exactly what the Smart Systems Stage is built for. What Sorbom and Kirtley will debate. According to TechCrunch, the session will go beyond hype to tackle three core questions: what recent breakthroughs are actually moving fusion forward, what technical and commercial challenges remain, and what it will take to deliver fusion power to the grid at scale. Expect sharp contrasts. Sorbom will likely detail CFS's high-field magnet advantage, SPARC's push for net scientific energy gain, or Q greater than 1, and how that de-risks ARC as a standardized, deployable power plant design. Kirtley is expected to counter with Helion's case for speed and cost: no steam turbines, no massive superconducting tokamak, but a compact system that compresses plasma to fusion conditions and captures electricity directly. Helion has argued this approach can achieve faster iteration cycles and lower capital cost per megawatt, a critical argument for utilities and hyperscalers. Both will face tough questions on timelines. CFS is aiming for SPARC operations and ARC grid connection in the early 2030s. Helion has held to a far more aggressive target of putting electricity on the grid by 2028. Investors, utilities, and skeptics will be listening closely. From breakthrough to bankable. The second half of the conversation is expected to focus less on plasma physics and more on power-plant reality: supply chains, tritium fuel, permitting, grid interconnection, and financing first-of-a-kind plants. That shift reflects where the industry is. Private fusion companies have now raised more than $9 billion globally, with CFS and Helion as the top two funded U.S. startups. The challenge is no longer just achieving fusion conditions, but doing it reliably, repeatedly, and at a price utilities will pay. Topics likely to come up include high-temperature superconductor manufacturing at scale, Helion's helium-3 and deuterium fuel strategy versus CFS's deuterium-tritium approach, workforce shortages, and how Big Tech's insatiable demand for 24/7 clean firm power is reshaping deal structures. For founders and investors at Disrupt, that commercial lens matters. Fusion's next phase will be won as much by execution, manufacturing, and project finance as by physics. What to watch at the session. For attendees, this is a rare head-to-head between two CEOs-turned-chief-scientists who rarely share a stage. Look for updates on SPARC assembly timeline, Polaris results, and any new announcements around utility partners, site permits, or 2027-2028 grid targets. TechCrunch Disrupt has a history of turning deep-tech showcases into breakout moments, and with energy for AI now a top-tier startup theme, fusion is moving to center stage. If Sorbom and Kirtley deliver, the takeaway won't just be that fusion works in the lab. It will be how, when, and at what cost it reaches your outlet.

Commonwealth Fusion Systems' Brandon Sorbom and Helion's David Kirtley on bringing fusion to the grid at TechCrunch Disrupt 2026. CFS' Brandon Sorbom and Helion's David Kirtley join the Smart Systems Stage at TechCrunch Disrupt 2026 to discuss the breakthroughs moving fusion forw For decades, commercial fusion power has seemed perpetually out of reach. Now two companies are building toward something much more concrete: putting fusion-generated electricity on the grid. Commonwealth Fusion Systems (CFS) is building SPARC, a demonstration fusion machine intended to pave the way for its first commercial power plant, ARC. Helion is developing Orion, a 50-megawatt fusion power plant intended to supply electricity to Microsoft beginning in 2028. At **TechCrunch Disrupt 2026**, CFS co-founder and chief science officer Brandon Sorbom and Helion founder and CEO David Kirtley will take the **Smart Systems Stage for "Bringing Fusion to the Grid."** They'll discuss the breakthroughs moving fusion forward, the challenges that remain, and what it will take to deliver fusion power to the grid at scale.

Moving fusion from science to commercial power. Sorbom co-founded CFS in 2018 with the goal of commercializing fusion energy in time to help combat climate change. As chief science officer, he leads the company's scientific direction and R&D and helps advance the design of ARC. The idea has roots in his work at MIT, where Sorbom was lead author of the paper proposing the original ARC design while earning his Ph.D. in nuclear science and engineering. Today, CFS is working toward ARC through SPARC, the company's demonstration fusion machine. In April, CFS became the first fusion company to apply to PJM Interconnection, the largest U.S. wholesale electricity market - a necessary step toward eventually connecting ARC to the grid. In July, the company raised another $1 billion, bringing its total funding to $4 billion. For founders and technology leaders, Sorbom brings a perspective that spans the journey from academic research to designing a commercial fusion power plant, and the scientific and engineering challenges that have to be solved along the way.
