Storing electricity with compressed air

Professor Seamus Garvey is a Professor at Nottingham University’s School of Engineering and he has been championing the concept of electricity storage by using compressed air. Storing electricity is hard to do in an environmentally acceptable way.

Electricity demand and supply is intermittent. Electricity generated from renewable sources is also intermittent. We can store electricity in large batteries (they do this in Japan) or we can use mechanical means of storing it. The most well known of the mechanical means is to build a dam and pump water into it when electricity is over supplied and let the water out through turbines when electricity is needed.
