Simple and Low-Cost
The technology uses traditional components and no exotic materials. The turbine power recovery system operates at near ambient temperatures.
Efficiency
Competitive but vastly cheaper.
Profile
Size and weight suitable for distributed generation with potential also for power rating equivalent to CCGT systems.
Versatile
Energy capture; energy storage and power recovery are decoupled.
Maximise the economic return
Along with power storage, the system has the ability to (i) harness waste heat; (ii) deliver air conditioning/refrigeration.
Environment
No emissions, minimal noise profile; components can be recycled at the end of its useful life.
Maintenance
All components are high reliability, low maintenance.
Safety
No hazardous, flammable or toxic liquids or materials. Cryogen stored at low pressure. Suitable for connection to local distribution networks and in small urban areas.
Durability
Low parts count and the elimination of low durability components gives a realistic design target of 20years+ overall plant-life potential.
Working fluid flexibility
System can be configured to use either liquid nitrogen (waste product for liquid oxygen production) or liquified air.
