Wind power liquid air energy storage

How efficient is a 100 mw liquid air storage system?

In a 100 MW system, the liquid air storage round-trip efficiency is 71.0% and the specific energy consumption is 0.189 kWh/kg, and the liquid hydrogen specific energy consumption is 7.87 kWh/kg and the exergy efficiency is 46.44%.

What is liquid air energy storage?

Concluding remarks Liquid air energy storage (LAES) is becoming an attractive thermo-mechanical storage solution for decarbonization, with the advantages of no geological constraints, long lifetime (30–40 years), high energy density (120–200 kWh/m 3), environment-friendly and flexible layout.

What is a standalone liquid air energy storage system?

4.1. Standalone liquid air energy storage In the standalone LAES system, the input is only the excess electricity, whereas the output can be the supplied electricity along with the heating or cooling output.

How much energy is saved by liquid air energy storage?

Since the liquid air energy storage process consumes 0.189 kWh/kg, the ratio of the energy saved per kg of liquid air over the energy consumed by the energy storage process is 28.0%. Fig. 14 shows the round-trip efficiency of the system.

What is the round-trip efficiency of liquid air energy storage?

In general, the round-trip efficiency of liquid air energy storage is defined as the electric energy generated by the turbine over the electric energy consumed by the air re-gasification process. The liquid air cold energy in this paper is mainly used to liquefy hydrogen, so the electricity generation is not significant.

Can wind energy be repurposed for energy storage?

One startup energy company is looking to reinvent not only wind energy, but also energy storage. Keuka Energy recently launched a 125-kilowatt prototype vessel that uses its novel floating wind turbine design paired with liquid-air energy storage to create a steady source of electricity.
