Liquid nitrogen seems to be attracting a bit of attention at the moment as a medium of energy storage, both for electricity grid applications and for transport. For example, Highview (via the Internet Archive) are doing round-trip electricity storage via liquid nitrogen.
Liquid air/nitrogen energy storage and power generation are studied. Integration of liquefaction, energy storage and power recovery is investigated. Effect of turbine and compressor efficiencies on system performance predicted. The round trip efficiency of liquid air system reached 84.15%.
Scheme 1 liquid nitrogen energy storage plant layout. At the peak times, the stored LN2 is used to drive the recovery cycle where LN2 is pumped to a heat exchanger (HX4) to extract its coldness which stores in cold storage system to reuse in liquefaction plant mode while LN2 evaporates and superheats.
energy density of liquid N X 2: 620 kJ/l = 712 kJ/kg (from presentation at Highview) Here's short report that gives ≈20% efficiency for producing liquid air in Egypt. They also give storage loss (ca. 0.17 \%/d) Thus, the 50% (achieved by Highview) to 70/80% (short term goal Highview against waste heat, quote for Dearman's engine) mean that
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. In an incident on January 12, 2006 at Texas A&M University, the pressure-relief devices of a tank of liquid nitrogen were malfunctioning and later sealed.
Unfortunately I don't have the time right now to check. According to Energy and Materials Flows in the Production of Liquid and Gaseous Oxygen (Shen and Wolsky, Argonne National Lab, 1980 ), the ideal (thermodynamically reversible) amount of work to liquify nitrogen is 21 400 J / m o l, or 0.21 k W h / k g (Table 12, page 17).
