The system consist of:

• Air compressor

• Air treatment/filters

• Nitrogen seperator

• Cryocooler

• Vacuum-insulated dewar

• Control electronics. 

Liquid nitrogen is inexpensive, especially production on-site:

Cost: as low as $0.13 per liter

Production energy required: From 0.2 kWh (720 kJ) per kg to a maximum of 0.6 kWh (1976 kJ) per kg depending on efficiency

Proven concept: A working single‑cylinder and V8 prototype is already operational, ready for scale-up to commercial units.

Because the liquid-to-gas expansion ratio of nitrogen is 1:694 at 20 °C (68 °F), a tremendous amount of force can be generated if liquid nitrogen is vaporized in an enclosed space. 

Why is this engine different

• No combustion, No emissions: Only a physical phase change from liquid to gas—no chemical reactions.

• Cost effective production process: Producing 1 liter of liquid nitrogen costs $0.13.

• No material depletion: The nitrogen can be used indefinitely in a closed loop.

• Universally available fuel: Nitrogen is in the air everywhere.

• Safe and stable: Non‑flammable, non‑toxic, easy to store and transport.

Applications

• Power Generation

• Vehicle Propulsion

• Marine Propulsion

• Rail propulsion

• Industrial rotating machines

The system consists of the following proprietary products:

• Liquid Nitrogen production unit.

• Liquid Nitrogen engine .

Cost effective power generation.

• Cost of Liquid Nitrogen production = $ 0.033

• Capital Cost of system amortized over 20 years per kWh produced = $ 0.012

Power Generation Energy Cost Comparison

• Production energy required:

• From 0.2 kWh (720 kJ) per kg to a maximum of 0.6 kWh (1976 kJ) per kg depending on efficiency.

• A V8 5,7L engine requires 1.22 L/min of Liquid Nitrogen to run.

• The engine can power a 200kw alternator.

• The requirement is 73.2 l per hour to produce 200 kWh.

• To produce 73.2 l of liquid Nitrogen requires 43.92 kWh (worst case)

• The cost to produce 73.2l of liquid nitrogen @ $ 0.15 is $ 6.59

• The selling price of 200 kWh @ $0.12 per kWh is $ 24.00
