What is liquid air energy storage?

Liquid air energy storage manages electrical energy in liquid form, exploiting peak-valley price differences for arbitrage, load regulation, and cost reduction. It also serves as an emergency power supply, enhancing the reliability of electricity supply to the consumer.

How liquefied air energy storage system works?

However, considering the basic configuration of the liquefied air energy storage system process, in previous studies, the high-pressure and high-temperature air at the compressor outlet enters the heat storage unit, releases heat, and cools down into high-pressure and normal-temperature air.

How liquid air is stored in a evaporator?

Liquid air is stored in cryogenic tanks. Low-temp liquid air from the storage tank is pressurized in a cryogenic pump, enters the evaporator to absorb heat and vaporize, then enters the turbine unit for multi-stage turbine and power generation (Zhang et al., 2020b).

What are the benefits of a liquid air energy storage system?

The only benefit that is reflected in the financial income calculation is the energy conversion income of the energy storage system. In accordance with the financial evaluation model of the energy storage system, each financial income index of the liquid air energy storage system can be ascertained.

How does a low-temperature liquid-air storage tank work?

Therefore, the low-temperature liquid-air storage tank, as the starting point of gaseous reflux air in the circulation branch, must have a close relationship between the working state of the storage tank and the working parameters of several components in the upper and lower links, and affect each other.

What is the operating income of a liquid air energy storage system?

In accordance with the comprehensive life cycle analysis calculation model, the operating income of a liquid air energy storage system encompasses dynamic income, capacity income, environmental income, and energy conversion income.
