Compressed Air In Salt Caves Could Help Shift To Renewable Energy

Compressed Air In Salt Caves Could Help Shift To Renewable Energy

Updated: Aug 1, 2019


Compressed air energy storage has been around for a while. Back in 1978, a CAES plant was built in Germany, which used a salt cave as the storage space. Since then, salt caves have grown in popularity as we discover the different benefits of these caves.


With another facility in Alabama, it can generate up to 110 megawatts of electrical power "within 14 minutes of startup during periods of peak demand."


The strategy behind this partnership of compressed air energy and salt caves is simple once you break it down. First, electricity from either a grid or some other renewable energy source pressurizes air and then the air gets stored at a high pressure underground. Then, when needed, the trapped air is let out heated and then expanded to produce the electricity required.


There's no limit on how long it can be stored, whether it be days, weeks, or even months, before it is needed. One company, Storelectric is wanting to make this technology more cost-friendly and energy efficient.


“You can’t store the air underground at much above ambient temperature,” Mark Howitt, CTO of the business, told CNBC. “But compressing the air heats it up to somewhere north of 650 centigrade,” he added.


With renewable energy sources on the rise and becoming more important to rely on each year, these types of energy storage systems will be in high demand.
