Solar Integration: Solar Energy and Storage Basics

Although using energy storage is never 100% efficient—some energy is always lost in converting energy and retrieving it—storage allows the flexible use of energy at different times from when it was generated. So, storage can increase system efficiency and resilience, and it can improve power quality by matching supply and demand.

Also this is an apples and oranges comparison. The tidal lift I described is a energy generation system not a storage. For a true tidal "energy storage" system, the hull/float would have to be locked down at low tide, the tide would have to come in and your release the float. You extract energy from the float bobbing back to the surface.
