Mazama Energy announced a superhot rock drilling performance milestone that the company says signals a turning point for the economics of engineered geothermal systems.
Pacific Fusion broke ground on a $1 billion Research & Manufacturing Campus at Mesa del Sol in Albuquerque, New Mexico, which will house its Demonstration System — designed to reach net facility gain by 2030 and to produce high-yield fusion bursts exceeding 100 megajoules, making it the only high-yield fusion facility under construction in the United States. The same day, the Department of Energy's National Nuclear Security Administration and Pacific Fusion announced a Memorandum of Understanding Regarding Collaboration on High Yield Fusion, High-Energy-Density Science and Related Technical Areas, signed by NNSA Administrator Brandon Williams and Pacific Fusion co-founder and CTO Keith LeChien. NNSA stressed the MOU is a framework only: specific projects and funding commitments require separate agreements. Federal, state and local leaders attended alongside investors including board member Eric Schmidt, and the company positioned the build explicitly against Chinese fusion investment.
SHINE said it was selected for the US Department of Energy's Genesis Mission, which the company describes as a more-than-$5-billion national initiative to double America's scientific output through AI. SHINE takes two roles: prime recipient on 'AI-Guided Fuel Cycle Facility Optimization', a Phase I project with Argonne National Laboratory as technical partner, and a contributing role on a second project. The lead project aims to produce an AI-enabled workflow letting engineers weigh performance, product quality and waste together when designing fuel recycling processes, building on two Argonne tools — AMUSE, which models separation chemistry, and ARTEMIS, which models full recycling facility layout — with a new AI layer co-developed with Argonne. No award value for either project was disclosed.
CFS announced (Jul 30) $1B in new equity, bringing total raised to ~$4B and roughly 30% of all private fusion investment globally — its largest single round since the $1.8B Series B in 2021. Notably the backers are pension funds, sovereign wealth funds and infrastructure investors, a first for the fusion industry, signalling a shift toward treating fusion as an infrastructure-grade bet. Proceeds de-risk ARC-specific systems and prep the first commercial site; SPARC is ~80% assembled with first plasma/net energy gain targeted for 2027.
Germany's Federal Ministry of Research, Technology and Space selected Biblis to become the home of the country's national laser fusion hub, with Focused Energy leading the effort. Biblis is a decommissioned nuclear power station site, and the selection is central to Focused Energy's plan to build Germany's first laser fusion power plant.
Tennessee Governor Bill Lee joined partners to present the nation's first-ever license specifically for a commercial fusion machine to Type One Energy at the Bull Run Site.
Pacific Fusion announced that Sirius, a pulsed-power prototype designed and built at Lawrence Livermore National Laboratory under a Cooperative Research and Development Agreement with the company, has surpassed 3,000 full-power shots. Sirius is an impedance-matched Marx generator (IMG) — a pulsed-power architecture that synchronises electromagnetic waves directly onto a common transmission line in a single step rather than inductively stacking voltage through conventional Marx banks, making it simpler, more efficient and easier to scale. It is the same core technology Pacific Fusion is scaling for its own system. CTO and co-founder Keith LeChien framed the campaign as evidence that national-lab technology can be validated by repeated testing and scaled quickly by industry, supporting both surging AI and electrification demand and high-yield experimental capability for stockpile stewardship.
Trump Media & Technology Group Corp (NASDAQ: DJT) filed a definitive merger proxy statement (DEFM14A) with the SEC on 13 July 2026 for its all-stock acquisition of TAE Technologies, eleven days after the preliminary version (PREM14A, 2 July 2026). A definitive proxy is the point at which the transaction goes to a shareholder vote, making this the most advanced procedural step to date toward TAE — a nearly 30-year-old private fusion company — obtaining a public listing. As of the end of August 2026 no Form 8-K reporting completion of the acquisition had been filed, so the transaction remained pending: the August 8-Ks carry items 2.02 (results) and 7.01 (Reg FD) only.
Lowercarbon Capital joined Focused Energy's Series A financing round, adding to the $240 million raised in May 2026. Focused Energy describes the round as the largest fully secured Series A in the global fusion industry.
On 1 July 2026 the UK Atomic Energy Authority announced that CFS will be the first international company to join LIBRTI (Lithium Breeding Tritium Innovation), a £220 million UK government initiative aiming to demonstrate net tritium production. CFS gains early access to a first-of-a-kind blanket-testing facility at UKAEA's Culham Campus, including a recently acquired high-flux neutron source. Tritium self-sufficiency — a plant breeding enough of its own fuel — is one of the hardest unsolved gates on fusion commercialisation, so access to representative blanket-test infrastructure addresses a specific critical-path risk rather than a general research interest. UKAEA framed the agreement as building on momentum from the King's Address to the U.S. Congress in April.
