Is underground compressed air energy storage a good idea?

Tina Casey recently wrote that underground compressed air energy storage is getting attention these days because it may be able to generate electricity for as long as eight hours whereas most grid-scale batteries have exhausted their power after three to four hours.

How long would it take to build a pumped hydro energy storage system?

When activated, it was the largest grid-connected CAES project of its size in the world, according to the China Energy Engineering Corporation, which claims an equivalent pumped hydro energy storage system would have taken six to eight years to complete.

How efficient is hydro energy storage?

Up to 70 percent efficiency is possible, which would make it equal to that of the flow batteries available today, while pumped hydro energy storage can achieve closer to 80 percent efficiency, China Energy said according to Energy Storage News.

Can you use compressed air in a conversion process?

You can even use compressed air. No matter what method you choose, there will always be losses associated with the conversion process. How big those losses are will be a major factor in determining whether any process is commercially viable.

How do you store energy?

Or follow us on Google News! There are may ways to store energy. You can convert it into electricity and store it in batteries. You can make a tower of 12 ton concrete blocks and move them up and down like the weights of a grandfather clock. You can pump water uphill and then make it spin turbines on the way back down.
