Nautilus Data Technologies holds the distinction of operating the world’s first commercially commissioned zero-water consumption data center — a floating facility at the Port of Stockton, California, independently commissioned by Black & Veatch. Nautilus’s patented EcoCore and TRUE (Total Resource Usage Effectiveness) cooling platform uses external water sources — seawater, river water, greywater, or reclaimed water — as the heat rejection medium in a sealed heat exchange process that draws zero potable water from community supplies, discharges zero pollution, uses no refrigerants or chemicals, and operates silently. The system achieves a verified daily PUE of 1.15 while supporting rack densities exceeding 100 kW — 70% more energy-efficient than traditional data centers. The Stockton facility was independently verified by Black & Veatch in a third-party due diligence report confirming all cooling, electrical, and machinery systems functioned as designed.
