Cosylab: Giving Control to Production Fusion Systems

July 9, 2026

The Fusion Report interviews Mark Pleško, CEO of Cosylab, a 250-person Slovenian company that has built control systems for ITER, UKAEA, and major research labs for over two decades. Pleško explains why fusion startups tend to treat controls as a problem to solve later, what that technical debt costs them, and how the Fusionics initiative co-founded with UKAEA aims to give the industry a standard control framework.

Commonwealth Fusion Systems and the UK Atomic Energy Authority Team Up on Tritium Production

/ July 1, 2026

Commonwealth Fusion Systems has become the first international partner in the UK Atomic Energy Authority’s LIBRTI program, a £220 million effort to demonstrate net tritium production for fusion power plants. The two organizations will jointly design the experimental setup and run investigations at a new facility being built at UKAEA’s Culham Campus, which will draw on a high-flux neutron source from Shine Technologies. CFS, which describes itself as the best-funded fusion company with more than $3 billion raised, will build the test articles used to validate the tritium breeding blanket design for its ARC power plant planned for Virginia. Tritium breeding blankets are a shared engineering challenge across fusion approaches, and cross-company collaboration on the technology is becoming more common as the industry moves toward first-of-a-kind machines.

Realta Demonstrates Direct Energy Conversion In a Fusion Energy Setting

/ June 30, 2026

Realta Fusion demonstrated direct energy conversion (DEC) of plasma kinetic energy into electricity at the WHAM fusion machine at UW-Madison, drawing current at about 100 volts to light several bulbs. The company describes it as the first such demonstration by a commercial fusion company and points to DEC as a way to raise efficiency and lower cost in its planned mid-2030s plants.

The Impact of AI and the Data Center Goldrush on Non-Data Center Construction Costs

/ June 25, 2026

The AI data center buildout is pushing up costs well beyond electricity and water. A recent study finds it is also raising the price of construction materials and skilled labor while absorbing capital that non-data-center projects, including commercial fusion, are competing for. The Fusion Report looks at who pays, who benefits, and what the $6.7 trillion data center forecast means for fusion’s race for investment.

E&P Technologies: Putting the Lightning into Capacitors for Fusion and Aerospace

/ June 23, 2026

As fusion energy moves closer to commercial deployment, The Fusion Report is expanding its coverage of the fusion supply chain. This piece profiles E&P Technologies, a Melbourne, Florida startup building high voltage pulsed power capacitors for fusion and aerospace, and includes an interview with co-founder and CEO Caroline Sorrick on US manufacturing and how rapidly evolving fusion requirements affect suppliers.

Helion Energy secured the licenses needed to operate a fusion power plant, clearing the way for its Orion plant in Malaga, Washington. General Atomics will collaborate with the DOE to design the first full-scale fusion blanket test facility. General Fusion’s roughly $1 billion merger with Spring Valley Acquisition Corp. III cleared SEC review, with a shareholder vote set for July 6. Type One Energy added former bp CEO Bernard Looney to its board, and Inertia formed a Science and Technology Advisory Board. The Fusion Report also looks at China EAST’s run at 2027 ignition, asks whether data centers belong in space, and refreshes its Top Fusion Companies by Funding tracker at $11.4 billion across 24 companies.

China EAST Gets Set for Ignition in 2027

/ June 18, 2026

China’s Experimental Advanced Superconducting Tokamak (EAST), the record-setting “Artificial Sun” in Hefei, is now scheduled to attempt fusion ignition in 2027, a milestone reached only once before, by Lawrence Livermore’s National Ignition Facility in 2022. If successful, EAST would be the first to achieve ignition in a steady-state magnetic confinement device, though Commonwealth Fusion Systems’ SPARC is racing toward the same goal on the same timeline. The Fusion Report breaks down what ignition actually requires (the Lawson Criteria of temperature, density, and confinement time) and assesses how close each machine really is. EAST leads on pathfinding plasma physics while SPARC targets Q > 1, but neither has yet crossed into a self-heating burning plasma. The bigger question: would a 2027 ignition milestone finally ignite broad investor interest across the fusion sector?

Putting Data Centers Into Space: Is That Really The Best Idea Elon Musk Has For SpaceX?

/ June 16, 2026

With SpaceX freshly public and its stock up 28% over the IPO price, talk of putting AI data centers in orbit is back in the headlines. The Fusion Report looks past the one obvious upside, nearly unlimited solar power in a sun-synchronous orbit, and tallies the costs that doom the idea: $160M to $280M per megawatt just to launch, two-year hardware refresh cycles, dense low-earth-orbit debris, space weather, and the near-impossibility of radiating away server heat in a vacuum. Against a ship-borne data center that fits in a shipping container and cools itself for a fraction of the price, orbital compute simply doesn’t pencil out. The verdict: outside of analyzing data that originates in space, orbital data centers are not a great idea.

The Department of Energy released its finalized Fusion Science and Technology Roadmap on June 9, built with input from more than 800 scientists and engineers, targeting commercial fusion by the mid-2030s. The same day, Tennessee became the first state in the nation to regulate fusion machines, clearing a path for Type One Energy’s Infinity Two plant near Oak Ridge. On June 10, DOE approved Xcimer Energy’s 724-page Athena preconceptual power plant design. The Fusion Report also goes deep on Realta Fusion’s Hammir-DT tandem mirror power plant design and Thea Energy’s collaboration with NVIDIA, Synopsys, Argonne, and PPPL to build a digital twin of its Helios stellarator.
