The Most Reliable Large Scale, Long Term Energy Storage Solution

LAES uses no rare earth materials with commercial off the shelf equipment with millions of hours proven reliability.

How it works

  • Air is liquefied by refrigerating it to -196°C
  • It is stored in cryogenic tanks as a dense liquid
  • Liquid air is vaporized back to gas on demand
The energy released during the vaporization process is used to drive turbines that generate electricity.

Specialty brazed aluminum plate fin heat exchangers are at the heart of liquefaction processes. Chart technology reduces the number of units and piping, which reduces overall project cost complexity, risk and schedule.


Driving efficiency

  • SuperGap™ high performance vaporizers provide zero cost heating during the vaporization process
  • Vacuum Insulated Pipe provides a thermal efficiency >10 times better than foam insulated pipe
  • Installation & Commissioning - everything from permitting assistance, to general contracting, final inspection/safety review, startup
  • Training - hands-on cryogenics and operator training in the classroom and the field
  • Onsite Maintenance & Service Packages - from first fill to fine tuning the system as well as extended warranty offerings for fixed project costs
