Enhancing Efficiency, AI Performance & Sustainability
1. Google Cloud’s Expanding AI & HPC Challenges
As Google Cloud Platform (GCP) scales up its services—powering AI, big data analytics, and machine learning (ML)—its data centers are under increasing pressure. The growth of ultra-powerful AI models such as Gemini and DeepMind, paired with Google’s TPUs and NVIDIA GPUs, is pushing power densities beyond 100 kW per rack. Compounding the issue is Google's ambitious 24/7 carbon-free energy goal by 2030, which conflicts with the water-intensive traditional cooling systems currently in use.
🔎 The problem?
Conventional air cooling breaks down beyond 30-50 kW per rack.
Evaporative cooling uses billions of liters of water annually.
Two-phase immersion systems are complex and costly.

2. Why Traditional Cooling Fails for Google Cloud
Challenge Traditional Cooling Limitation
High-Density Racks Airflow limitations lead to hotspots
Sustainability Goals Evaporative cooling is water-intensive
Advanced AI Hardware Needs uniform thermal management
Two-Phase Cooling Involves evaporation, chip modifications, and high cost
Google Cloud's rapid AI workload expansion calls for next-gen cooling that's energy-efficient, eco-friendly, and compatible with existing hardware.
