Our Patented designs enable the air we all breathe every single day to serve as a type of “fuel” for powering transportation vehicles and other equipment. With our proprietary systems, Liquid Air/Nitrogen can match, and in some use cases, exceed the specific energy of state of the art Lithium Ion batteries at the pack level. Since we use a thermo-mechanical method of storing and converting energy, we have the ability to convert the thermal energy that has traditionally been discarded back into additional electricity or other forms of work. Waste heat from system components plus the energy from regenerative braking provides the ability to exceed the energy density of previous designs based around Liquid Air/Nitrogen.

specific energy

Specific Energy is one of the single most important metrics in the entire world of energy. The potential energy carried by Liquid Air/Nitrogen is just over 200 Wh/kg (watt hours per kilogram). Under moderate ambient conditions and by capturing waste heat from the system itself, our solutions can average approximately 125 Wh/kg.

Use cases with a heavy stop-n-go duty cycle can average higher specific energy (due to regenerative braking), where use cases with limited stop-n-go could have lower averages depending on operating parameters.
