The U.S. Department of Energy has committed $107 million to a new round of fusion energy research collaboratives, marking one of the largest federal bets yet on a power source that, if it works at scale, could supply virtually limitless clean electricity to cities, factories, and even global shipping fleets. The funding announcement lands as private investors and oil majors are also placing significant capital on fusion subsystems, while political entanglements on both sides of the Atlantic threaten to complicate the path from laboratory breakthroughs to commercial reactors.
Federal Dollars Meet Private Capital in Fusion’s Big Push
The Department of Energy selected teams for its Fusion Innovation Research Engine collaboratives, a program designed to accelerate the jump from physics experiments to working power plants. The initiative builds on the Milestone Program, which borrowed its structure from NASA’s approach to partnering with private aerospace companies. That earlier effort started with an initial $46 million federal commitment, yet it triggered a far larger wave of private spending: awardees have collectively raised over $350 million since their selection, according to the same DOE announcement, underscoring how public money can catalyze private risk-taking in a technically demanding field.
The ratio matters. For every federal dollar committed through the Milestone Program, private investors put up roughly seven and a half dollars of their own. That leverage effect is exactly what policymakers hoped for when they modeled the program on NASA’s Commercial Crew and Cargo partnerships, which helped SpaceX and other firms mature faster than traditional government contracting would have allowed. The DOE’s fusion sciences office, and the broader research apparatus tracked through the federal science archive, now support a growing ecosystem of startups and university labs chasing different reactor designs, from tokamaks to stellarators to compact approaches that barely existed a decade ago. Alongside these efforts, the department’s Genesis initiative is being positioned as a broader framework for clean energy innovation, with fusion research expected to sit alongside advances in grid technology and low-carbon fuels.
Neutral Beams Draw Google and Chevron Into the Race
While the federal government funds broad research collaboratives, some of the sharpest private money is targeting a specific piece of the puzzle. A fusion group backed by Google and Chevron is moving to commercialize neutral-beam technology, according to Financial Times coverage of the sector. Neutral beams inject high-energy particles into plasma to heat it toward the extreme temperatures required for fusion reactions. They are not a reactor design in themselves but rather a critical subsystem that multiple fusion approaches need, which makes them a potentially profitable product even before any fusion plant generates its first watt of electricity.
That commercial logic is worth examining closely. Most fusion startups face a chicken-and-egg problem: they need billions of dollars to build a working reactor, but they cannot generate revenue until the reactor is finished. By selling neutral-beam hardware to other fusion developers, research labs, and even non-fusion industrial customers, a company can create a revenue stream that sustains operations during the long development cycle. Google and Chevron appear to be betting that this hybrid model, part technology supplier, part future reactor builder, offers a more durable path than waiting years for a single massive project to pay off. Programs like the DOE’s high-risk, high-reward ARPA-E portfolio have similarly tried to push fusion components toward near-term commercial viability rather than treating the entire field as a distant moonshot, funding technologies that could stand alone as products even if full-scale reactors take longer than expected.
Geopolitical Friction Tests Fusion Partnerships
Capital alone will not determine whether fusion reaches the grid. International partnerships are essential because no single country holds all the talent, materials, and regulatory frameworks needed to commercialize a new class of power plant. Yet those partnerships are increasingly tangled in political complications. A reported deal between the Trump family and a fusion energy firm has added friction to the already complicated relationship between U.S. and UK atomic energy institutions, according to subscription-linked analysis of the governance issues involved. Parallel licensing information highlights how access to detailed reporting on these arrangements is itself mediated through institutional channels, reflecting the way fusion has moved from a niche scientific topic into a politically sensitive commercial arena.
The tension is not purely symbolic. Fusion research depends on open data sharing, joint experiments, and cross-border supply chains for specialized components like superconducting magnets and, yes, neutral-beam injectors. When political figures with business interests become entangled in those relationships, it can slow regulatory approvals, chill academic cooperation, and create conflicts of interest that erode public trust in the technology itself. For an industry that still needs sustained government funding on both sides of the Atlantic, that trust deficit carries real financial consequences. The International Energy Agency has long documented how cross-border cooperation on energy technology accelerates deployment timelines. Any disruption to that cooperation could push fusion’s commercial arrival further into the future by delaying joint demonstration projects and complicating export controls on advanced components.
Fusion’s Place in a Crowded Clean Energy Field
Even optimistic fusion advocates acknowledge that working reactors are still years away from producing grid-scale electricity. In the meantime, other clean energy technologies are advancing rapidly. Stanford’s SETR 2026 assessment examines iron-air batteries as a way to store energy generated by intermittent wind and solar power, addressing one of the biggest practical barriers to a renewable grid. These batteries use cheap, abundant iron instead of expensive lithium, and they can discharge stored energy over days rather than hours, making them well suited to filling gaps when the wind stops or clouds roll in. As storage, transmission upgrades, and demand-response systems all improve, the baseline need that fusion must meet becomes more specific: clean, firm power that can backstop a high-renewables grid without driving up costs or emissions.
Fusion’s promise, though, is qualitatively different from better batteries or cheaper solar panels. A working fusion reactor would produce energy on demand, without fuel supply constraints, carbon emissions, or the long-lived radioactive waste associated with conventional nuclear fission. That profile makes it uniquely attractive for applications where batteries and renewables struggle, such as powering large cargo ships on long ocean crossings, supporting energy-intensive industrial processes that require constant high-temperature heat, or delivering reliable power in regions with limited land for wind and solar farms. The challenge for policymakers is to nurture fusion’s long-term potential without starving near-term climate solutions of funding and attention. The current mix of federal programs, from collaborative research engines to component-focused grants, suggests a recognition that fusion must be developed in parallel with, rather than in place of, other clean technologies if it is to play a meaningful role in decarbonizing the global energy system.
