Green energy is a popular topic right now, with many countries signing on to the Paris Climate Accord and planning to move away from fossil fuels toward renewable energy.
While most countries are working toward establishing solar and wind power farms, some countries like Canada are looking toward the creation of compressed air storage plants for power storage and generation.
How can compressed air change the way countries use and store green energy?
Compressed Air as Energy Storage
Compressing air in porous caves can serve as a backup form of power that can be tapped when the demand for power is high. Essentially, the compressed air is stored in caves of porous basalt rock when power demand is low. When more power is needed, the air is heated and piped through turbines to generate power.
