Storing Energy in Underwater Bags

Storing Energy in Underwater Bags
Jul-16-14
By storing energy in underwater bags, Hyrostar hopes to provide way to even out the electricity production of offshore wind farms.

The bags, called "flexible accumulators," would be anchored under the water at a depth of 80 meters, where the weight of the water would pressurize the air within the bag and allow more energy to be stored by volume. When the stored energy is needed, the pressure from the water would push air to the surface and through an expander, where it would power a generator and supply energy to the grid.

The Hydrostar team has focused on using existing components as much as possible, which provide a known life-span and are also more familiar to technicians.
