Summary
The article profiles Sizable Energy, a startup developing a novel approach to energy storage using flexible reservoirs in the ocean. Inspired by traditional pumped-storage hydropower, the company aims to store excess renewable energy by pumping water into flexible underwater reservoirs when electricity is cheap, then releasing it through turbines to generate power when needed. The startup has raised $8 million to test prototypes of this ocean-based energy storage system, which could provide grid-scale storage for renewable energy sources like wind and solar.

The technology, known as pumped-storage hydropower, or 'pumped hydro' for short, has been around for over a century. Such facilities are some of the biggest 'batteries' humans have ever built.
