Commonwealth Fusion Systems

“There are companies like Commonwealth Fusion that are very close — the energy going out will be more than the energy coming in. So fusion could be huge in the next 5 to 10 years.” –Steve Pagliuca, senior advisor to Bain Capital, the firm’s former managing director and co-chair, and co-owner of the Celtics, at #WEF2025 in Davos, Switzerland. Why the investments in fusion? “Because you have to power these facilities to get us the power we need to run the AI,” he said in conversation with Maria Bartiromo on Fox Business Network. #FusionEnergy #AI #Davos

The cryostat base, which is a foundational piece for SPARC, our fusion demonstration machine, is on its way to Commonwealth Fusion Systems. This year is a big year for us as more and more pieces come together for SPARC.

“It’s easy to fall into a trap that because energy has been done a certain way, it will always be done that way.” Today at the World Economic Forum (WEF) in Davos, Switzerland, our CEO Bob Mumgaard said our work to bring fusion energy to the grid means it’s also time to rethink how we power our homes, vehicles, and industries. WEF attracts the world’s movers and shakers from government and business, and Bob shared the stage with notable figures like Kimberly Budil, the director of Lawrence Livermore National Laboratory; Sophie Hermans, Minister of Climate Policy and Green Growth of the Netherlands; Hans Kobler, Founder of Energy Impact Partners; and Xin Baoan, Chairman of China' Global Energy Interconnection Development and Cooperation Organization. Here’s some of what Bob had to share: • Fusion will change energy. Instead of being limited by resources, energy will tap into technology industry advantages like steadily improving products and dropping prices. • The world’s top brains are tackling energy, filling university programs and launching startups. “The energy sector is actually the hardest sector to get into at the hardest universities. We're going to see a pipeline fill and then 10 years from now, a whole bunch of technologies to pick from.” • Fusion regulations exemplify the benefits that a fresh look can bring. “Five years ago, there was no regulation. That didn’t stop us. We started to build a plant and we said we'll figure it out. Now that regulation is set, and it's a completely different regulation in the United States than nuclear power. It’s much more innovation-forward.” • Fighting climate change isn’t necessarily a zero-sum game in which progress in one area means problems in another. Instead, the fight will spawn huge, beneficial new industries. “It’s a giant problem — but it’s a giant solution.” You can watch the panel here: https://lnkd.in/g7Femf4m #WEF2025 #FusionEnergy

There are plenty of questions about the future of energy — and fusion power could settle many of them. It'll be a reliable, round-the-clock complement to wind and solar power, filling the gaps when the sun isn’t shining or the wind isn’t blowing. That's what we need as electrifying cars, homes, and industries leads to a rise in electricity generation by 30% to 76% by 2050, according to the US Energy Information Administration. Here's why fusion is a good fit for the grid's needs. For one thing, it’ll be adaptable. It'll be able to generate steady baseload power or ramp up and down to follow the daily electricity use patterns. Our ARC power plants can be flexibly located, for example built where old coal plants once stood to reuse existing infrastructure and reduce the need for new power lines. With abundant fuel, the spread of fusion power will be governed more by energy demand than by resource limits that are so common in the energy industry today.

We’re ramping up our commercialization work at Commonwealth Fusion Systems (CFS). In the newest of our twice-yearly video updates, CEO Bob Mumgaard details the importance of choosing a site in Chesterfield County, Virginia, for our first fusion power plant, ARC. Putting watts on the grid in the early 2030s is a big step in our long-term plan to bring our clean, zero-carbon fusion energy to the world. Here’s the look from inside CFS at what else has happened in the past six months. We have: • Completed the manufacture of more than half of the toroidal field (TF) magnet “pancakes” we need for our first tokamak, SPARC • Begun stacking poloidal field (PF) pancakes into our first PF magnet, a pulsed-power design • Finished manufacturing and testing our Central Solenoid Model Coil (CSMC) magnet, proving out our pulsed magnet technology We’ve hit our peak manufacturing velocity at our Magnet Factory here in Devens, Massachusetts. And two key tokamak components, the cryostat base and vacuum vessel, are due soon at our headquarters that we moved into two years ago. This video offers some first looks at that hardware. The next step is assembling the SPARC tokamak, our first fusion machine. Two orange stands in Tokamak Hall await the first TF magnets, and supporting subsystems for heating, power, and cooling are rapidly arriving in the building around Tokamak Hall. We’re also sharing some first or early looks at new hardware, including of our magnet-testing cryostats and one of our welding robots in action. 2024 was a big year for CFS. Stay tuned as SPARC’s fusion hardware comes together in 2025.

Imagine a world powered by the same force that fuels the sun — limitless, clean energy that transforms economies and reshapes industries. That’s the promise of fusion. The global race for fusion energy is happening now. With CFS announcing the first grid-scale fusion power plant in Virginia, we're headed toward a revolution that could make energy scarcity a thing of the past. Our CEO Bob Mumgaard joins Khosla Ventures’ Vinod Khosla in the World Economic Forum blog to detail how fusion will improve sustainability and economic growth around the world and lower the cost of the energy transition. “The jump from fossil fuels to fusion energy will inevitably be more profound than the jump from burning wood to burning fossil fuels.” https://lnkd.in/gwDZi82S #FusionEnergy #CleanEnergy

The world’s first grid-scale fusion power plant now has a home. We’ve announced the location for ARC in Chesterfield County, Virginia. We'll start generating energy in the early 2030s, the start of a massive shift toward clean, zero-carbon power that's available on demand. It'll transform the energy industry as we know it.

Big, big week for us at Commonwealth Fusion Systems and for the fusion industry as whole. Can't wait to break ground for the first ARC power plant. Virginia, here we come!

Virginia is for fusion lovers. Our CEO Bob Mumgaard and Virginia Governor Glenn Youngkin joined CNBC Squawk Box this morning to discuss the historic announcement that we'll build ARC, the world's first grid-scale fusion energy power plant, in Chesterfield County, Virginia. ARC, a fusion energy device called a tokamak, will supply 400 megawatts of continuous fusion power to the customers in the state beginning in the early 2030s. We're grateful for the warm reception ARC has received so far by the state of Virginia, and look forward to engaging with the community as we deliver on our promise. Fusion is the last energy source humanity will need — offering a firm supply of clean, zero-carbon power, using essentially unlimited fuel, benefiting from inherently safe operations, and producing no greenhouse gas emissions.

Fusion is coming... to Chesterfield County, Virginia. In an enormous development for Commonwealth Fusion Systems and for the commercialization of fusion energy, CFS has committed to build the world's first grid-scale fusion power plant, ARC, in Virginia. We evaluated more than 100 sites around the world before settling on this location, a good site with good infrastructure and a strong appetite for the firm supply of power we'll provide. We'll independently finance, build, own, and operate this first-of-its-kind technology so we can start generating clean, carbon-free energy in the early 2030's. We'll also collaborate with Dominion Energy Virginia to help smooth ARC's path to the grid, benefitting from their development and technical expertise while helping the utility learn about fusion. ARC will produce about 400 megawatts of electricity — enough to power 150,000 homes in the area or some of the largest commercial and industrial sites.
