This Startup Wants to Power AI Data Centers With Nuclear Energy—and Just Raised $380 Million

Blue Energy Global Inc., a nuclear power company spun out of MIT, has raised $380 million in funding from investors led by VXI Capital. This is one of the largest funding rounds ever for companies building small modular reactors—essentially, smaller, factory-built nuclear power plants rather than the massive ones traditionally built on-site.

The company has now raised more than $425 million in total since launching two years ago. The timing matters: tech companies like Google, Microsoft, and Amazon are desperately searching for clean, reliable electricity to power their artificial intelligence data centers around the clock. Nuclear power is increasingly seen as the only realistic way to provide that without depending on weather or fossil fuels.

A Different Way to Build Nuclear Plants

Here's where Blue Energy differs from traditional nuclear companies. Instead of building reactors on-site over a decade, the company plans to manufacture modular reactor systems in existing shipyards, then assemble them on location—much like building a ship in pieces and putting it together elsewhere.

The goal is ambitious: reduce the cost of building nuclear plants from roughly $10,000 per kilowatt of power down to $2,000 per kilowatt, and cut construction time from 8 to 10 years down to just 2 years.

To sidestep the lengthy regulatory approval process that has historically bogged down nuclear startups, Blue Energy has chosen not to build its own reactor design. Instead, it partners with existing reactor vendors whose designs have already been approved by the Nuclear Regulatory Commission. This is pragmatic: the company focuses on the manufacturing and assembly challenge, not on inventing new reactor technology.

An Underwater Nuclear Reactor

Blue Energy is also experimenting with underwater small reactors—reactors submerged in water to handle cooling and potentially ease public concerns about nuclear safety. This is relatively novel territory, and it could solve practical challenges around land use and heat management.

Texas as the Proof-of-Concept

The company plans to build a nuclear facility in Texas capable of producing 1.5 gigawatts of electricity—about 1.5 times the output of a typical single nuclear reactor. The facility is designed to supply power directly to data centers. This will be Blue Energy's first major real-world test, and a crucial moment to prove that the modular, manufacturing-based approach actually works.

Analysis: This scale signals that Blue Energy is not chasing a niche market. The company is positioning itself as a utility-scale nuclear developer, just using factory-built components rather than traditional on-site construction methods.

Who's Backing Blue Energy

The company's earlier funding round, which closed in late 2024, was co-led by Engine Ventures and At One Ventures, with backing from several other investment firms. The leadership of this new, much larger $380 million round by VXI Capital is significant: it signals that institutional investors—the kind who fund major infrastructure projects—believe in Blue Energy's business model.

This confidence matters because nuclear plants are extraordinarily expensive to build. The nuclear industry has a checkered history of cost overruns and delays. Investors are essentially betting that Blue Energy has found a way to break that pattern.

Why MIT Matters Here

Blue Energy came out of MIT's Nuclear Science & Engineering Department in 2023, which means it inherited deep technical expertise and decades of nuclear research. This academic pedigree provides credibility and access to ongoing research at one of the world's leading universities.

Blue Energy is not alone: other nuclear startups, like Commonwealth Fusion Systems, have also spun out of MIT and other top research institutions, using university research as the foundation for commercial nuclear power ventures.

The Market Opportunity

The sudden interest in nuclear power from Big Tech is real and unprecedented. Google, Microsoft, and Amazon have all announced deals to secure nuclear power in recent months. They need electricity that runs 24/7, never depends on sunshine or wind, and produces no carbon emissions. Traditional utility companies have been slow to build new nuclear plants. That gap is where Blue Energy sees its opening.

The company's approach—manufacturing plants efficiently and financing them through project-based funding rather than relying entirely on venture capital—addresses a real industry problem. Building a nuclear plant costs billions of dollars, money that venture investors alone cannot reliably provide. Blue Energy's model lets industrial investors and infrastructure funds step in once a plant is being built according to a clear timeline and budget.

Worth flagging: Blue Energy's promise to reduce nuclear costs to $2,000 per kilowatt would be transformative—the biggest improvement in nuclear economics since the 1960s. However, the nuclear industry has a long history of missing cost targets. These goals should be viewed as the company's aspiration until it proves them with actual, completed projects.

Can They Actually Do This

The two-year construction timeline is the real gamble. Traditional nuclear plants take 8 to 10 years to build, sometimes longer due to regulatory delays and on-site problems. If Blue Energy can consistently deliver in 2 years, it would fundamentally change how quickly nuclear power can respond to demand. Currently, utilities have to plan nuclear plants a decade in advance. A two-year timeline would allow nuclear to be deployed almost like other power sources.

By relying on existing reactor designs rather than developing proprietary ones, Blue Energy avoids reinventing the regulatory wheel. That is a smart shortcut—as long as it works in practice.

What This Means for Nuclear's Future

The speed at which Blue Energy has raised money—over $400 million in less than two years from stealth—speaks to how hungry investors are for solutions to the clean electricity problem. The company's ambitions are utility-scale, not niche: it wants to make nuclear the cheapest baseload electricity source available, cheaper even than coal or natural gas.

If Blue Energy succeeds in delivering the Texas facility on time and on budget, other companies will likely copy the approach. That could mark a genuine turning point for nuclear power, transforming it from a decade-long infrastructure bet into something closer to a standard industrial process.

The next few years will tell whether this optimism is justified or whether Blue Energy, like many nuclear ventures before it, runs into the hard limits of nuclear economics and regulation.
