New and recently funded Energy Startups

Country: USA | Funding: $31.5M
Apollo Atomics intends to create a water nuclear reactor (from 10 to 300MW) and is rethinking the way thermal energy is converted into electricity. The startup has managed to shrink the steam generator and make the whole system way more compact than any other reactor in the market. With the compactness of the generator in mind, Apollo plans on assembling the reactor and steam generator in a factory rather than on site, which is the case with nuclear power plants today. Apollo has already built a small, 40-kilowatt reactor with MIT to demonstrate the technology. It plans to deploy the first commercial power plant in 2028 and generate electricity at a rate of 3 cents per kilowatt hour.

Country: Netherlands | Funding: €42.5M
Thorizon is building a molten salt modular reactor that will use long-lived nuclear waste in combination with thorium as fue. It was founded as a spin-off from the Netherlands’ national nuclear research institute, where molten salt technology was developed quietly for decades. The reactor will use nuclear waste as fuel and provide both power and high‑temperature heat with sufficient safety. Thorizon’s patented cartridges divide the reactor core into smaller modules, unlocking the benefits of off-site series production and modular scalability. Easy to operate, move, and deploy, these cartridges make building reactors faster and more flexible than ever. The first plant construction will start in the early 2030s.

AMPERA develops next-generation subcritical thorium-based microreactor systems for AI data centers, that are energy dense and do not require refueling. Its nuclear module is designed to provide decades of reliable carbon-free power with exceptional energy density, safety, and longevity. The company also plans to process the raw thorium in-house at its facility in Florida and to use its proprietary jetting technology to manufacture high-quality Tri-structural Isotropic (TRISO) fuel kernels.

Kraken is a spinoff of Octopus Energy, a company building a virtual grid for renewable energy supply. Kraken is the AI software that manages this grid, and Octopus has decided to sell it separately to other energy utilities. Kraken provides a suite of tools for managing the grid and customer base, forecasting load and income, organizing support and creating new products and tariffs. It also enables field operations management, including collaboration with local contractors, real-time network data retrieval to monitor performance, identify faults and allows to precisely manage capacity loads arising from the expansion of distributed energy sources. Kraken supplies its energy software to such utility companies as EDF and E.ON.

Cambridge AtomWorks is focused on delivering a nuclear micro-reactor ODIN built in the UK. The startup intends to demonstrate the first nuclear micro-reactor operational prototype by 2030 and by the mid-2030s - become a trusted global supplier of clean, sustainable energy to off-grid customers. ODIN is a low-pressure, molten-salt-cooled, solid-fuel fission reactor integrated with power conversion and heat rejection systems, enabling substantial and compact, standalone electricity supply without external connections.
