How to add nitrogen to the energy storage device

Can we capture atmospheric nitrogen and store energy in a battery?

AsianScientist (Apr. 26, 2017) – In a study published in Chem, researchers from China have developed a way to capture atmospheric nitrogen and store energy in a battery at the same time. As the most abundant gas in Earth’s atmosphere, nitrogen is an attractive option as a source of renewable energy.

How much liquid nitrogen is enough to store 2600 J?

The variation of liquid volume during this experiment is plotted in the same figure (dashed line, right scale): actually, 13 cm 3 of liquid nitrogen would be enough to store 2600 J between 65 and 83.5 K using an expansion volume of 6 L.

How does a lithium nitride battery work?

Instead of generating energy from the breakdown of lithium nitride (Li 3 N) into lithium and nitrogen gas, the researchers’ battery prototype runs on atmospheric nitrogen in ambient conditions and reacts with lithium to form lithium nitride. Its energy output is brief but comparable to that of other lithium-metal batteries.

What is an energy storage unit?

An energy storage unit is a device able to store thermal energy with a limited temperature drift. After precooling such unit with a cryocooler it can be used as a temporary cold source if the cryocooler is stopped or as a thermal buffer to attenuate temperature fluctuations due to heat bursts.

Does nitrogen gas break apart under normal conditions?

But nitrogen gas—which consists of two nitrogen atoms held together by a strong, triple covalent bond—doesn’t break apart under normal conditions, presenting a challenge to scientists who want to transfer the chemical energy of the bond into electricity.

How much energy does a system store?

Between 65 K and 83.5 K, the whole system stored an useful energy of 3720 J (solid line in Fig. 5, calculated as Q applied t) and the parasitical power (circles) is accounted for an additional total energy of ≈50 J to be stored by the system.
