Things You Gotta Know

Global Fusion Investment Climbs to $9.77 Billion
Fusion fund flows surged by $2.64 billion in the past year, pushing total private investment since 2021 to $9.77 billion—five times higher than at the beginning of that period. That marks a 178 percent rise over last year, across the U.S., Europe, Japan, China and Britain. The Fusion Industry Association notes investor confidence may be maturing, though most firms still say they need far more capital to reach commercialization.

Avalanche Energy Clears 300 kV Threshold in Desktop Fusion System
Seattle-based Avalanche Energy sustained 300,000 volts in a compact fusion module for multiple hours. That milestone represents a key technical advance toward their goal of a desktop-scale reactor that could surpass input energy.

Surging Fusion Funding Signals Transition to Energy Transition
Investor interest is accelerating as fusion technologies begin matching broader climate goals. Fueled by growing AI-related electricity demand and high-profile corporate backers, the sector is seen as a bridge to low-carbon baseload power. Analysts say fusion firms must now scale supply chains and demonstrate repeatable breakthroughs to keep momentum.

UK Moves to Streamline Planning for Fusion Projects
The UK government is preparing to relax site licensing and planning requirements for fusion energy installations. These regulatory steps aim to foster commercialization of fusion research and support forthcoming plants under the UK fusion strategy.

Marathon Fusion Explores Turning Mercury into Gold via Nuclear Transmutation
Marathon Fusion claims its neutron-rich fusion technique can convert mercury isotopes into stable gold within days. The concept integrates into conventional fusion reactors' tritium breeding blankets. One gigawatt plant could hypothetically produce 5,000 kg of gold per year.

CIBC Podcast Examines Fusion as Clean Energy Game‑Changer
Michael Ginsberg of Tokamak Energy joins Tom Heintzman, Vice Chair, Energy Transition and Sustainability, to discuss the promise of nuclear fusion, the challenges and opportunities to commercialize fusion technology, and its potential to transform future energy markets.

What Are The Critical Pieces In The Fusion Supply Chain, and How Do They Impact the Road to Commercial Fusion?

Fusion energy’s supply chain will make or break commercialization timelines. Each component requires specialized suppliers and engineering expertise. Let’s examine the companies and challenges driving these critical links.

The State of the Fusion Energy Industry in 2025: A Global Transformation in Progress

In 2025, the fusion energy industry sits at a pivotal moment. What was once a field confined to academic laboratories and governmental research programs is now rapidly evolving into a commercially driven, globally competitive energy sector. According to the 2025 Global Fusion Industry Report by the Fusion Industry Association (FIA), fusion no longer seems like a technology perpetually 20 years away—it is an energy solution actively being engineered, tested, and piloted for commercialization in this decade.
