Nordstone | CO₂ Storage Vessel

Precision-Engineered Solutions for Safe Carbon Dioxide Storage

A CO₂ Storage Vessel is a specially designed pressure tank engineered to safely store carbon dioxide (CO₂) in either liquid, gaseous, or supercritical states. CO₂ storage requires high mechanical strength, pressure integrity, and compliance with global safety standards because carbon dioxide has unique thermodynamic behaviors including high vapor pressure, risk of dry ice formation, and rapid expansion during pressure drops. Our CO₂ storage vessels are engineered to deliver maximum reliability and safety across industrial, food-grade, medical, and energy applications.

What Is a CO₂ Storage Vessel?

CO₂ Storage Vessels

A CO₂ storage vessel is a pressure-rated container engineered for storing:

•
Liquid CO₂ at cryogenic temperatures (typically –20°C to –40°C)
•
High-pressure gaseous CO₂
•
Supercritical CO₂ for EOR, carbon capture, and advanced industrial processes
