Company Overview
Sizable Energy is an Italian company founded in 2022 that is developing a novel offshore energy storage solution. Its patented technology is a form of pumped-hydro storage that utilizes the gravitational potential of sea salt brine, moving it between a reservoir on the ocean floor and a floating surface reservoir.
