According to a recent LinkedIn post from Zap Energy, the company is pursuing both fission and fusion approaches that appear to share a common technical base. The post highlights compact, modular system dimensions of roughly 3–4 meters in core size and an output range of 10–50 MWe, supported by alkali metal cooling using sodium and lithium.

The LinkedIn post suggests that liquid metal engineering, neutronics and shielding analysis, materials qualification under irradiation, and thermal-hydraulic design are core competencies leveraged across both platforms. It also points to shared work on supply chain, manufacturing, and regulatory pathway development, which could create efficiencies as the company scales.
According to the post, Zap Energy sees fusion-fission hybridization as opening new technological possibilities, with safety described as an inherent and primary consideration in both programs. For investors, this integrated approach may indicate potential for platform-based cost sharing, broader addressable markets in advanced nuclear, and a diversified route to eventual commercialization, although timelines and regulatory outcomes remain key uncertainties.
