Bluecore Energy’s $50M Seed Round Puts Floating Nuclear in Focus

Bluecore Energy announced an oversubscribed $50 million seed round just months after raising a $10 million pre-seed and coming out of stealth. The round closed in eight weeks, according to TechCrunch, with Silverton Partners leading. Existing backers including Slauson & Co., Harlem Capital, and Ripple co-founder Chris Larsen participated again, alongside new investors including Collab Capital and HartBeat Ventures.

The speed of the raise signals strong investor interest in clean-energy infrastructure startups, especially those tackling power access for ports, data centers, and nearby communities. For readers tracking venture trends, the key point is momentum: Bluecore moved from stealth to a major seed round in a short window.

Founded by Kofi Asante earlier this year, Bluecore Energy builds small nuclear reactors on floating barges rather than fixed sites. The goal is to generate clean energy for ports and nearby infrastructure while making power easier to move to where it is needed. Asante told TechCrunch the company is making portable nuclear technology smaller so it can be moved in “days” rather than requiring years or new infrastructure.

The concept targets customers and communities that need cleaner, more flexible energy sources. Bluecore says it has seen inbound interest from multiple ports, AI data centers, and communities that need clean energy and water.

Bluecore became the first nuclear company headquartered at a major port when it emerged from stealth at the Port of Long Beach in July. Since then, it has launched two floating barges and struck a partnership with the Department of Transportation Maritime Division, the U.S. Nuclear Regulatory Commission, and the U.S. Coast Guard. The company is now undergoing review with the NRC and Coast Guard on its product design.

If that process is successful, TechCrunch reports it would lead to certification of Bluecore’s floating nuclear power plant. Asante said the company had been speaking with both agencies since inception and formally began engagement in August.

The fresh funding will support product development, regulatory work, nuclear fuel purchases, and hiring. Asante identified supply chain execution as the biggest challenge, especially securing hardware fast enough to build portable electricity infrastructure that can meet demand.

Bluecore’s team includes people from SpaceX, Rivian, and Toyota, and Asante said the company is applying similar strategies to secure critical parts. He also said the company already has barges and a reactor and is preparing to order nuclear fuel for a partner at a national nuclear lab.
