One startup’s quest to store electricity in the ocean
The article profiles Manuele Aufiero and his startup, Sizable, which aims to revolutionize energy storage by adapting pumped hydro technology for offshore use. Pumped hydro, a century-old method of storing electricity by moving water between reservoirs at different elevations, currently accounts for a significant portion of global energy storage. However, traditional pumped hydro requires site-specific concrete dams, limiting scalability and deployment. Sizable’s innovative approach uses two sealed, flexible reservoirs—one floating on the ocean surface and one on the seabed—connected by a tube and turbines. By pumping super salty water upward when electricity is cheap and releasing it to generate power when demand is high, the system effectively lifts and lowers a heavy salt solution to store and release energy. Sizable has tested prototypes in wave tanks and off the coast of Italy and plans to deploy pilot projects ahead of commercial-scale plants by 2026. Each turbine is expected to generate 6 to 7 megawatts, with multiple reservoirs per site enabling significant storage capacity
