How Hydrostor Aims To Change The Power Game By Storing Energy Under Water

There has been a fair bit of concern in recent years about the ability of our power plants to supply adequate electricity during periods of peak demand. Hydrostor, a Toronto-based company, is taking a different approach and offering a solution that allows plants to store their power using compressed air in underwater storage tanks. Hydrostor converts excess electricity into compressed and stores it under a body of water, when the electricity is needed the weight of the water forces the air back to the surface where it's converted back into electricity. This technology allows for the removal of renewable energy intermittency, decongestion of transmission and distribution lines, and better efficiencies of existing generation.
