Apollo Atomics Secures $45M to Scale Compact Nuclear Steam Generators for AI Power Grids

Clean tech startup Apollo Atomics has closed a $45 million Series A funding round led by climate tech venture funds to commercialize miniature steam generation components designed for Small Modular Reactors (SMRs).

As massive AI data centers strain regional electrical grids, hyperscalers are turning to dedicated on-site nuclear energy. Apollo Atomics' compact steam generator design reduces the physical footprint of SMR heat exchangers by 60%, allowing rapid modular deployment directly adjacent to AI compute facilities.

The company plans to deploy its first pilot thermal unit by late 2027, offering data center operators continuous zero-emission baseload power independent of public electrical utility grids.
