Towards Bio-Nucleated Cold Storage for Resilient Computing Infrastructure

Abstract: Direct-to-chip liquid cooling may be changing the thermal architecture of computing facilities, but it does not eliminate every low-temperature load or potential use for flexible thermal storage. This paper proposes bio-nucleated cold storage as a physically isolated auxiliary layer rather than part of the primary server-cooling loop. This paper is adapted from Project Z-Freeze, which is an untested student project; its public documentation describes computational design and a hypothetical wet-lab pathway. Given the extensive research in temperature-gradated cooling, demand-responsive liquid cooling, ice thermal energy storage, computational ice-nucleating-protein (INP) design, and cell-free INPs, the novelty claim is specific: can a recoverable engineered biological nucleator offer measurable additionality in an isolated cold-storage layer, and can this be falsified against state-of-the-art non-biological alternatives? The paper combines a targeted literature review, an illustrative thermodynamic scaling model and a staged validation framework. The model separates latent storage capacity, nucleation-related freezing behavior, and whole-system electricity use; it does not predict Z-Freeze performance. Scaling suggests that short-duration mini-, micro- and edge-data-center applications may be physically easier to prototype than multi-megawatt backup, although maintenance and containment may weigh more heavily at small sites. Validation therefore prioritizes stochastic nucleation measurement, matched non-biological controls, cycling and water-chemistry tests, full-system energy measurement, lifecycle assessment, and safe isolation. Cell-free or non-replicating forms are preferred unless living systems demonstrate a necessary functional advantage. The contribution is a falsifiable architecture and evidence standard, not a claim that biological nucleation has already improved data-center cooling.
