"You can provide enough fuel to power the entire fusion power plant for its entire lifetime … just sitting there from day one, which really changes how you think of energy security.” 1/4

3/4 Fusion energy offers a clean, steady, and abundant energy source can be built just about anywhere, including places that rely on pipelines and tanker ships today. When we use SPARC to demonstrate Q>1 — net fusion energy — then fusion energy will be a big step closer to fulfilling that promise.

CFS and the U.S. Dept. of Commerce have signed a letter of intent for a proposed $85 million award that would advance semiconductor research and development for fusion energy. 1/6 cfs.energy/news-and-med...

5/6 We expect the proposed award from the CHIPS Research and Development Office (CRDO) to attract new suppliers and partners to the fusion sector. Building a more robust industrial base will help bring this clean, safe, nearly limitless form of energy to the grid as fast as possible. #FusionEnergy

3/6 It would fund a variety of semiconductor-related innovation that applies to fusion energy, including improvements to power electronics, radio frequency power generators, controller chips, robotic maintenance equipment, and artificial intelligence for fusion.

“We have a saying at CFS that in the future, the two markets that matter are energy and gray matter. It’s really human creativity and energy, and then the possibilities are endless.” 1/3 #FusionEnergy #TechCrunchDisrupt

2/3 That’s Brandon Sorbom, CFS Chief Science Officer and Co-Founder, speaking about the long-term potential of fusion energy at @techcrunch.com Disrupt 2026 this week. Quality of life measurements rise with energy, he added:

Q>1 is one of the most important milestones on the path to fusion power. But what does it actually mean? Alex Creely, Chief Engineer of ARC, breaks it down in simple terms. 1/3 #FusionEnergy #Energy #Physics #Science

2/3 Fusion has the potential to unlock a huge amount of clean energy. But first, a fusion machine has to prove it can make more energy than it uses. That’s what Q>1 means. It’s not the only thing a fusion power plant needs—but it’s a crucial first step.

We’re getting another useful tool in our fusion toolkit with a Genesis Mission award from the @departmentofenergy.bsky.social. Through the program, CFS will lead a group of U.S. labs, universities, and companies to use AI and digital twins to help catalyze commercial fusion energy work. 1/3

2/3 We already have work underway to use AI to improve how SPARC will work, but this Genesis Mission Phase II award will help us expand and deepen that work — for example by tapping into decades of historical fusion data and marshaling the power of DOE supercomputers to improve AI models.

"SPARC was designed with the intent not to be connected to the grid but to have 13 of the 17 systems you need in a power plant to show the world that we have a near-scale fusion machine that can work as a power plant... 1/4

3/4 That's Jennifer Ganten, Chief Global Affairs Officer, chatting with Dan Hewitt on the Everything Energy podcast from @iea.org, alongside other fusion observers. Jennifer and Dan discussed how the SPARC facility has become a beehive of daily activity with hundreds of people onsite.

"We forget that up until the Wright brothers, there were people saying that [flight] was physically impossible — despite the evidence that birds fly." 1/3

2/3 Fusion is the energy source of the sun and stars, and as CFS CEO and Co-founder Bob Mumgaard points out during this chat with @axios.com, NIF in California proved it can work on Earth, too.

In a one-day sprint 10 years ago, researchers at @mit.edu helped chart the CFS path to commercializing fusion energy — even before CFS was actually founded. 1/5

4/5 During that last day, researchers showed three separate paths to high performance in a competition to push the machine as far as it could go. It set a record that stands to this day, unmatched by any other tokamak.

2/5 That sprint took place during the last day of service for Alcator C-Mod, a type of fusion machine called a tokamak. C-Mod is the progenitor of the SPARC demonstration machine we’re building today and the ARC power plant we’ve begun designing. And we’re putting the C-Mod lessons to good use.

Fusion energy is often discussed as a matter of plasma physics, funding, and machine design, but bringing commercial fusion to the grid also requires a global industrial base that can manufacture critical components at scale. 1/4

4/4 We already built a supply chain for our SPARC fusion demonstration machine, but this agreement helps secure HTS tape for our next chapter: building ARC power plants, starting with our first at the Fall Line Fusion Power Station in Virginia.

2/4 Today CFS took an important step toward meeting that need, announcing an agreement to purchase more than 10,000 km (3 GA-m) of high-temperature superconducting (HTS) tape from Fujikura Ltd. It’s the largest single purchase order for HTS tape, a critical component of our breakthrough magnets.

“Think about what [fusion] means in a technological race. Power is the thing that powers the next economy, right? All the geostrategic strife we have right now is about power in the form of natural resources... 1/5

4/5 The world today is heavily influenced by the acquisition, management, and consumption of finite resources like fossil fuels that we currently use to power the globe.

2/5 ...Who has them? What are they? What boats are they on through what body of water? Fusion takes all of that off the table.”

#FusionEnergy costs are indeed key to its eventual success. Those costs are deeply connected to a fusion company’s choice of architecture, where it’s critical not only that the eventual power plants can be economical, but fundamentally, that a commercially relevant machine can actually work. 1/3

2/3 That’s what we’re tackling with our SPARC machine outside Boston. Our project got a head start thanks to many years of collective operational experience that people have gained by running tokamaks around the world (over 150 machines over the last 50+ years).

It was a bustling and productive week at #ClimateWeekNYC, and our team joined a variety of conversations about subjects on everyone's mind — not just climate, but also energy security, AI, and more. 1/3

2/3 Because one of the strongest tools to tackle climate issues — energy — also addresses other challenges around the world, and #FusionEnergy has a big role to play there.
