Samsung C&T has committed $100 million in equity and services to nuclear startup Kairos Power to support Google’s AI data center energy needs. This investment focuses on the Hermes 2 reactor, targeting completion by 2030. While small-scale nuclear technology aims to provide reliable power for AI, investors should watch for potential regulatory hurdles and the significant costs associated with building new nuclear infrastructure.
Engineering firm Samsung C&T has announced an investment of up to $100 million in Kairos Power, a startup focusing on advanced nuclear energy. This commitment includes $70 million in equity and $30 million in engineering services. The deal is part of a larger plan to help power Google’s growing AI data center needs, which require a consistent and reliable energy supply.
The investment centers on the Hermes 2 reactor, a project located in Oak Ridge, Tennessee. This reactor is designed to generate 50 megawatts of power and is expected to come online by 2030. The broader goal of the partnership between Google and Kairos Power is to reach a total power generation capacity of 500 megawatts by 2035.
Technically, Kairos Power uses a different approach compared to traditional nuclear plants. Instead of standard water-cooled systems, it uses a fluoride salt-cooled design. This method operates at lower pressures, which developers suggest can reduce risks during system failures. The reactor also uses TRISO fuel technology, which encapsulates uranium within carbon and ceramic layers to prevent the release of radioactive material even under high temperatures. These design features are intended to make the plant safer and easier to scale than older, larger nuclear plants.
While the technology aims to solve energy challenges, nuclear power projects face inherent risks. Construction of nuclear reactors requires enormous capital and often faces long timelines. Even with regulatory approval from the Nuclear Regulatory Commission, projects can experience delays due to technical complexities, rising costs, or strict safety requirements. Investors should be aware that while the demand for carbon-free energy from AI data centers is rising, successfully bringing these new reactor designs to commercial scale remains a complex challenge for the industry.
Looking ahead, the key monitorables for stakeholders include the construction timeline of the Hermes 2 reactor, further regulatory progress, and the ability of the company to keep project costs in check. The success of this collaboration may depend on whether the engineering support from firms like Samsung C&T can help bridge the gap between design and actual energy generation.
