Blue Energy will prefabricate most reactor modules in shipyards and barge them to site after raising $380m of equity and debt to fund a 1.5GW plant in Texas, the company said.

A factory approach to nuclear Blue Energy, a US start-up led by Jake Jurewicz, wants to move a large share of nuclear plant construction out of open-air sites and into shipyards. The idea is simple: build reactor modules in the controlled environment of a shipyard, then transport them by barge to the final location for assembly. That model borrows from an industrial playbook used in other heavy projects and from vendors who prefabricate maritime equipment. "The nuclear power technology that's most common — light water reactors — was originally invented for nuclear submarines," Jake Jurewicz, co-founder and chief executive of Blue Energy, said. He sees the shipyard route as a return to a long-standing practice rather than a reinvention. The company says centralising work in one place should reduce on-site labour, improve quality control and open the door to more automation. Those are familiar goals for industries that have shifted to modular construction to manage cost and schedule risk. The financing and the project Blue Energy closed a financing package totalling $380m, split between equity and debt. The round was led by VXI Capital, with participation from At One Ventures, Engine Ventures and Tamarack Global. The funds are intended to kick-start the firm's first full-scale project — a 1.5 gigawatt power plant expected to start construction later this year in Texas. The company is not pitching a novel reactor design; instead it is focused on how reactors and power stations are built. Jurewicz says the approach was inspired in part by export terminal construction in the liquefied natural gas sector. "They cut the schedule in half doing this, which was very disruptive," he said, referring to lessons drawn from that industry. Once modules are complete in the yard, Blue Energy plans to move them by barge to the installation site. The firm argues that near-complete assemblies reduce the time spent on complex, weather-exposed work at remote locations. Why the approach matters Interest in new ways to deliver nuclear has sharpened as grids strain under electrification and demand from AI data centres. Builders of large reactors have recently faced notable cost overruns and delays in the United States, prompting developers and utilities to seek alternatives that promise predictability. Key effects of the shipyard-prefabrication approach: - Concentrates specialised labour, equipment and inspection regimes in a controlled manufacturing environment. - Reduces weather-exposed on-site work and the duration of complex field assembly. - Shifts certain logistical and regulatory risks to maritime transport and integration at the destination site. Prefabrication is not a silver bullet; transporting heavy, complex reactor components requires robust maritime logistics and regulatory clearances, and modules still need skilled integration on arrival. Blue Energy's bet is that the changed risk profile and repeatable factory processes will, over time, cut unit costs. The funding round gives the company runway to test that assumption at scale with its Texas project. Implications for the UK British policymakers and industry will watch developments such as Blue Energy's with interest. The UK has large decarbonisation targets and a long record of naval shipbuilding and civil nuclear activity. A modular, shipyard-based build model could appeal to planners who want to limit long civil projects on exposed sites and to firms looking for export opportunities.

Construction on the 1.5GW Texas plant is expected to start later this year, offering the first large-scale test of whether shipyard prefabrication can cut costs and speed delivery. "It really minimizes the amount of construction on site, and it moves pretty much everything into a manufacturing environment," Jurewicz said.
