Fusion to the grid: CFS and Helion leaders on breakthroughs at TechCrunch Disrupt 2026.

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.

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. How do you turn decades of fusion research into commercial power? **Secure your Disrupt pass and grab a second at 50% off** to hear from one of the scientists working to make that transition. Putting fusion power to the test. Kirtley founded Helion to develop fusion technology that could ultimately deliver electricity at commercial scale. An NSF and NASA Advanced Concepts Fellow, he has expertise in high-Beta plasmas for energy and space propulsion applications and today leads Helion as it works toward commercial fusion power. In February, Helion announced that its Polaris prototype had heated plasma to 150 million degrees Celsius. The company is now developing Orion, a 50-megawatt fusion power plant intended to supply electricity to Microsoft as early as 2028. In June, Helion announced a key regulatory milestone on the path to building and operating the plant. Its Series G funding round, initially announced at $465 million in June, closed at $500 million in September. That timeline puts the questions at the heart of the Disrupt session into sharp focus. Scientific milestones matter, but commercial fusion also has to make the leap to a functioning power plant capable of reliably delivering electricity to customers.

Everett-based fusion startup Helion adds Seattle office, hits 800 employees.

Everett-based fusion startup Helion adds Seattle office, hits 800 employees. SEATTLE - Helion Energy, the Everett-based fusion company aiming to build the world's first commercial fusion power plant, opened a downtown Seattle office Tuesday for its business team as part of its expansion. CEO David Kirtley announced the move on LinkedIn, saying Helion has grown from 80 employees to 800 over the past four years at its Everett headquarters. The Seattle office will support further company-wide growth, he said. Governor Bob Ferguson, in a statement on X praised the expansion, noting that Helion now employs people in Everett, Seattle and Chelan County. Ferguson, who recently spoke at Fusion Week in the Tri-Cities, said the state's fusion research and the plant under construction position Washington as a global leader in the field. "Our state is home to the cutting-edge research that makes this industry possible, and the first commercial fusion energy facility under construction," Gov. Ferguson wrote. "Excited for more clean energy and good jobs in our state." Helion, founded in 2013, relocated its headquarters to Everett around 2022. It is constructing the Orion facility in Malaga, Chelan County, designed to deliver at least 50 megawatts of electricity to Microsoft data centers beginning in 2028 under a 2023 power purchase agreement. In June, Helion became the first company to receive Washington Department of Health licenses for radioactive materials and air emissions at the site. The company has raised more than $1.5 billion and was valued at $15.5 billion after a $465 million funding round earlier this year. State lawmakers have classified fusion as clean energy, separate from traditional nuclear fission, to ease permitting. Fusion remains unproven at commercial scale, and experts note significant technical hurdles remain before any plant can deliver reliable grid power. Helion and fellow Everett startup Zap Energy have both helped make Washington state a hub for private fusion development.

CATL makes first nuclear fusion investment, leads funding round in Beta Fusion.

CATL makes first nuclear fusion investment, leads funding round in Beta Fusion. Battery giant backs Chinese fusion startup as it expands beyond EV batteries into next-generation clean energy technologies Discover more Electric vehicle charging Electric motorcycles Electric bike sales CATL, the world's largest electric vehicle battery manufacturer, has made its first investment in the nuclear fusion sector by leading a seed funding round for Chinese startup Beta Fusion, signaling a strategic expansion into one of the most closely watched future energy technologies. According to Chinese media reports citing people familiar with the transaction, the funding round was worth several hundred million yuan. The investment marks CATL's debut in the nuclear fusion industry as the company continues to broaden its ambitions beyond battery manufacturing and energy storage. Fusion startup targets commercial power generation. Beta Fusion was established in December 2025 and focuses on the commercialization of controlled nuclear fusion technology. The company is led by founder and Chief Executive Officer Cao Zhiping, a Chinese scientist specializing in field reversed configuration (FRC) fusion technology. The startup's technical team includes researchers and engineers from several of China's leading fusion research institutions and national scientific projects. Discover more Autos & Vehicles Electric Vehicle Beta Fusion aims to develop fusion systems capable of delivering between 50 MW and 100 MW of grid-connected electricity within the next six to eight years. The company is pursuing the FRC fusion approach, a technology pathway also being developed by US-based fusion company Helion Energy. Industry observers consider the FRC route one of the most ambitious approaches to commercial fusion, offering the potential for faster deployment but carrying higher technological risks compared with more established fusion concepts. Growing interest in fusion energy. Nuclear fusion has attracted increasing attention from governments, investors and technology companies because of its potential to provide abundant carbon-free electricity using widely available fuel sources. Unlike conventional nuclear fission, fusion generates energy by combining atomic nuclei and is viewed as a long-term solution for producing large amounts of clean baseload power with minimal emissions. China has identified fusion energy as a strategic technology area and included it within its long-term national development priorities. The technology is also drawing renewed interest from the technology sector as artificial intelligence, cloud computing and hyperscale data centers drive rapid growth in electricity demand worldwide. Strategic expansion beyond batteries. For CATL, the investment aligns with its broader vision of evolving from a battery manufacturer into a comprehensive clean energy company. Founder and Chairman Robin Zeng has previously stated that energy generation, storage and grid management could become significantly larger business opportunities than electric vehicle batteries over the long term. The company has increasingly invested in energy storage systems, zero-carbon energy infrastructure and grid-related technologies as part of that strategy. Fusion energy could eventually complement CATL's existing energy storage and battery businesses by providing large-scale clean electricity generation for industrial users, utilities and data centers. Following a broader industry trend. CATL is not the first Chinese new energy company to back nuclear fusion technology. In 2023, electric vehicle manufacturer Nio invested 995 million yuan in fusion startup Neo Fusion, acquiring a 19.9% stake in the company. The growing involvement of EV and battery companies reflects increasing recognition that future energy demand will require solutions extending beyond transportation electrification alone. Strong financial position supports new investments. CATL enters the fusion sector from a position of financial strength. The company reported first-quarter 2026 revenue of 129.13 billion yuan, representing a year-on-year increase of 52.45%. Net profit attributable to shareholders rose 48.52% to 20.74 billion yuan during the same period. CATL also maintained its dominant position in China's battery market. According to industry data, the company installed 33.08 GWh of batteries in May, accounting for a 46.14% share of the country's power battery market. While commercial fusion power remains years away from large-scale deployment, CATL's investment in Beta Fusion highlights growing confidence among major industrial players that fusion technology could become an important part of the future global energy mix. As demand for clean electricity continues to rise, particularly from AI infrastructure and energy-intensive industries, investments in advanced energy technologies are expected to play an increasingly important role in shaping long-term energy strategies.
