Bluecore Energy raised $10 million in a pre-seed round led by Slauson & Co. to build small modular nuclear reactors mounted on floating barges, targeting ports and data centers as its first customers. Founder Kofi Asante, a former Uber Freight executive, started the company just seven months ago -- an unusually fast path from founding to a funded, physical hard-tech product with secured infrastructure already in place.
The technical design is deliberately simple: a water-cooled, closed-loop small modular reactor heats water into steam, which spins a turbine to generate electricity, all housed on a barge that can be towed by ship to wherever power is needed. Because the entire power plant moves rather than requiring years of fixed-site construction and permitting, Bluecore's pitch is that it can bring clean baseload power to a port or coastline in days rather than the decade-plus timeline typical of conventional nuclear buildouts. The reactor design only needs refueling once every few years.
“Each barge is designed to power roughly the equivalent of 15,000 homes, or to scale up to meet the electricity needs of an entire major port.”
Bluecore has already secured a port terminal, a barge, and a test reactor pressure vessel -- concrete physical assets rather than just a pitch deck, and it's headquartered at the Port of Long Beach, which the company says makes it the first SMR company to base its operations inside a major US port. Each barge is designed to power roughly the equivalent of 15,000 homes, or to scale up to meet the electricity needs of an entire major port.
The target customer set -- ports and data centers -- lines up directly with the two fastest-growing sources of new US electricity demand: data centers are expected to use roughly four times more electricity by 2035, and ports face growing pressure to electrify operations that have historically run on diesel. A reactor that can be towed in rather than built on-site addresses both markets' shared problem: getting reliable power to a location faster than the grid or a traditional plant can provide it.
What to watch: how quickly Bluecore can move from a secured test pressure vessel to an operational reactor, and whether nuclear regulators treat a barge-mounted, mobile reactor design differently from fixed-site SMR licensing pathways.
