Underwater compressed air energy storage.
7 1 p ρ sw g d where ρ sw is the density of seawater typically 1025 kg m 3 and g is acceleration due to gravity 9 81 m s 2 using equations from chapter.
Compared with a fixed volume underground.
Underwater compressed air energy storage uw caes a step beyond underground energy storage in caverns may soon offer conventional utilities a means of long duration load shifting for their large scale electrical grids and niche microgrid operators a means of reducing their fossil fuel dependence say its advocates.
A brief review of land based caes storage indicates limited potential only two plants with a total capacity of 400mw 4gwh one of which is 40 years old.
Compressed air energy storage it is possible to obtain curves of energy density against depth for an underwater compressed air store assuming the air is stored at a.
It is very similar to underground caes in all aspects but the energy store.
The gauge pressure in seawater at a depth d is given by.
Uwcaes is a developing storage technology which is a natural extension of caes for coastal environments.
