Liquid air system could compete with batteries
According to the Institute of Mechanical Engineers, a storage system that cools the air to liquid again could pose stiff competition for energy storage batteries.
What makes this system is cool and store air (gases) that is composed mostly of nitrogen and once in that state, is stored in a vacuum container which is kept at very low temperatures until required.
When using this air is required, which is made is to raise the temperature of the container until liquid is converted into gas again and begins to vaporize, which in turn causes a high pressure which, when released can move even turbines Electric.
The advantages of this are:
- If built well and with quality materials, the storage tank, the turbine, and the pipe cryogenic refrigerator can last for about 20 years.
- To heat the air can be used residual thermal energy from electrical generators and even in the same refrigerator condenser is used to cool the air. This would have a 70% efficient.
- If enough heat is provided, you can download the stored energy extremely fast and to regulate it (make it slow down), simply remove some heat without expensive electronics.
Now, only one question remains in the air How much is all this build and maintain? If in the long run, maintenance is cheap would be a great option for storing energy “efficiently” as long as the cooling system does not fail.
