Companies Cool on Gas: Modular Data Centers on Pipelines

Sapphire Technologies and Anax Power propose placing modular data centers directly on US gas pipelines: turboexpanders use pressure drops in pipes to generate electricity and cold coolant. Sapphire estimates this cuts energy and cooling operating costs by about 2%.

• US has 210 gas pipelines totaling 305,000 miles
• 2×1 m turboexpander produces power and cooling from pressure drop
• Magnetic bearings reduce friction and extend device lifespan
• Energy and cooling savings estimated at 2% of operating costs
