6 FAQs about [Underground compressed energy storage]

Can compressed air energy be stored underground in a depleted oil reservoir?

During this study, the underground storage of compressed air energy in a naturally fractured depleted oil reservoir was numerically simulated using the STARS module of CMG software. Air storage consists of two stages. In the first stage, the cushion gas is injected and develops the initial bubble in the reservoir.

What are the five underground large-scale energy storage technologies?

In this work, the characteristics, key scientific problems and engineering challenges of five underground large-scale energy storage technologies are discussed and summarized, including underground oil and gas storage, compressed air storage, hydrogen storage, carbon storage, and pumped storage.

How is energy stored in compressed air?

In Germany, a patent for the storage of electrical energy via compressed air was issued in 1956 whereby “energy is used for the isothermal compression of air; the compressed air is stored and transmitted long distances to generate mechanical energy at remote locations by converting heat energy into mechanical energy” .

Can a positive experience from underground storage of natural gas be extrapolated to compressed air?

The positive experience gained from underground storage of natural gas cannot be directly extrapolated to compressed air storages because of the risk of reactions between the oxygen in the air and the minerals and microorganisms in the reservoir rock.

Can compressed air energy be stored in depleted hydrocarbon reservoirs?

Compressed air energy storage in underground structures, including depleted hydrocarbon reservoirs, due to having a suitable storage capacity for air and because their geological characteristics have already been well identified, is one of the storage methods.

Why is compressed air storage important?

Compressed air storage in underground formations is an excellent way to balance energy production and consumption. During off-peak hours, with the consumption of excess electrical energy, the air is temporarily stored at high pressure in the desired environment.
