Aalo Atomics Raises $100M Series B for Microreactors

Aalo Atomics Secures $100M for Nuclear Microreactors

Nuclear startup Aalo Atomics has raised $100 million in a Series B to build a microreactor and co-located data center, accelerating the development of next-generation nuclear power for the AI-driven energy transition.

Microreactors Meet AI Data Centers

Aalo's approach combines two of the most significant trends in energy and technology: modular nuclear reactors and the surging power demands of AI data centers. By co-locating a microreactor with a data center, the company can provide dedicated, carbon-free, always-on power directly to the computing infrastructure that needs it most. This eliminates grid transmission losses and provides the reliability guarantees that hyperscale AI workloads demand.

The Nuclear Renaissance Thesis

The $100M Series B reflects growing investor conviction that nuclear energy is entering a structural growth cycle. AI data centers require gigawatts of reliable baseload power that renewables alone cannot provide. Microreactors offer a path to deploy nuclear capacity faster and with less capital risk than traditional large-scale nuclear plants, making them particularly attractive for distributed power generation near data center clusters.
