The energy landscape is shifting beneath our feet, and nowhere is this more apparent than in Canada’s bold gamble on fusion power. While traditional energy markets fluctuate and climate deadlines loom ever closer, a Vancouver-based startup is quietly revolutionizing how we think about both clean energy and investment opportunities. This isn’t just another renewable energy story—it’s the birth of an entirely new financial sector.
General Fusion’s journey from laboratory curiosity to Wall Street darling represents something unprecedented: the world’s first pure-play fusion power company preparing to trade on public markets. Unlike the massive government-funded projects that dominate headlines, this Canadian innovator is taking a radically different approach, one that could reshape both the energy industry and how investors access the most promising technology of our time.
The emotional weight of this moment cannot be overstated. For decades, fusion has tantalized scientists and engineers with its promise of clean, limitless energy. Now, ordinary investors can own a piece of that dream, while a small Canadian company prepares to prove that commercial fusion isn’t just possible—it’s profitable.
Canada’s Fusion Finance Revolution
General Fusion is making history by becoming the first publicly traded company whose core business centers entirely on commercial fusion power. The Vancouver-based firm has struck a transformative deal to merge with Spring Valley Acquisition Corp, a US-listed SPAC (Special Purpose Acquisition Company) designed specifically to bring promising companies to public markets.
This financial maneuver carries profound implications beyond mere fundraising. The transaction values the combined entity at approximately $1 billion, supported by:
- $100 million from an oversubscribed private fundraising round
- Nearly $220 million from the SPAC’s cash reserves
- Additional institutional backing from strategic partners
- Potential for further capital raising through public markets
The funds aren’t destined for executive bonuses or flashy marketing campaigns. Every dollar is earmarked for a singular purpose: completing and operating General Fusion’s flagship experimental machine, known as Lawson Machine 26 (LM26), and accelerating development toward a grid-scale prototype.

“We’re not just building a reactor—we’re building an industry,” explains General Fusion CEO Christofer Mowry. “This public listing gives us the capital and credibility to move from demonstration to deployment at the speed climate change demands.”
LM26: The Full-Scale Dress Rehearsal
Lawson Machine 26 represents more than engineering ambition—it’s a full-size dress rehearsal for commercial fusion power. Already built and operational, LM26 serves as General Fusion’s first full-scale demonstrator for Magnetized Target Fusion (MTF), a hybrid approach that combines elements of magnetic confinement and inertial confinement fusion.
The machine’s chamber measures roughly half the diameter of a future commercial reactor, allowing engineers to test not just plasma physics, but real-world challenges like component durability, maintenance protocols, and thermal management that actual power plants will face.
| Development Phase | Temperature Target | Key Milestone | Timeline |
|---|---|---|---|
| Phase 1 | 1 keV (10 million°C) | Plasma stabilization and control | 2024-2025 |
| Phase 2 | 10 keV (100 million°C) | Efficient fusion reactions begin | 2025-2026 |
| Phase 3 | Lawson Criterion | Net energy gain achievement | 2027-2028 |
| Commercial Demo | Commercial conditions | Grid-scale prototype | 2030+ |
Pistons Instead of Giant Magnets
While most fusion projects pursue enormous magnetic fields or powerful lasers, General Fusion has chosen a radically different path: mechanical pistons. Their reactor design features dozens of synchronized pistons that slam into a metal sphere filled with swirling liquid lithium.
This synchronized impact creates compression waves that travel toward the center, where pre-heated, magnetized plasma awaits. The liquid lithium serves dual purposes:
- Forms a protective liquid wall shielding solid components from intense heat and radiation
- Acts as a breeding blanket for tritium, the fusion fuel that must be produced on-site
- Provides a self-healing surface that can withstand repeated compression cycles
- Enables easier maintenance compared to solid wall designs
“The beauty of our approach lies in its mechanical simplicity,” notes Dr. Michel Laberge, General Fusion’s founder. “While others build ever-larger superconducting magnets, we’re using principles that worked for steam engines—just applied to fusion physics.”
The Investment Landscape
General Fusion’s public debut arrives at a crucial moment for clean energy investing. Traditional renewables face supply chain constraints and intermittency challenges, while nuclear fission carries political and waste disposal burdens. Fusion promises to solve both problems, offering baseload power without long-term radioactive waste.
The investment thesis extends beyond environmental benefits:
- Global energy demand projected to increase 30% by 2040
- Fusion market potentially worth $1 trillion annually by 2050
- First-mover advantage in commercial fusion technology
- Government support through various clean energy initiatives
- Corporate partnerships with major utilities and tech companies
Global Competition and Collaboration
General Fusion isn’t operating in isolation. The global fusion landscape includes government mega-projects like ITER in France, private ventures such as Commonwealth Fusion Systems and TAE Technologies, and national programs in the UK, China, and Japan.
“Competition in fusion is actually collaboration in disguise,” observes Dr. Sarah Johnson, an energy policy analyst at the University of Toronto. “Every breakthrough, regardless of source, advances the entire field closer to commercial viability.”
What distinguishes General Fusion is its focus on near-term commercial deployment rather than pure scientific achievement. While ITER aims to demonstrate sustained fusion by 2035, General Fusion targets commercial prototypes by 2030.

Technical Challenges and Solutions
Despite the optimism, significant technical hurdles remain. Achieving the Lawson criterion—the specific combination of temperature, density, and confinement time required for net energy gain—has eluded fusion researchers for decades.
General Fusion’s approach addresses several key challenges:
- Heat Management: Liquid lithium walls handle extreme temperatures better than solid materials
- Fuel Supply: On-site tritium breeding reduces dependency on external sources
- Maintenance: Mechanical components can be serviced without dismantling the entire reactor
- Scalability: Piston-driven compression scales more predictably than magnetic confinement
