Sizable Energy is at the forefront of renewable energy storage solutions, dedicated to developing a low-cost, highly efficient, and scalable offshore pumped-hydro storage system. Our innovative approach combines the strengths of proven PHES hydraulic machinery technology with the benefits of offshore deployment, resulting in a storage solution that is cheaper than batteries, less carbon-intensive, and effortlessly integrated with floating offshore wind farms. Our unique technology features a simple yet effective design, utilizing a reservoir on the ocean floor, one floating on the surface, a connecting pipe, and reversible pump-turbines. Gravitational potential energy storage is obtained by pumping upwards heavier than water saturated seasalt brine. This design allows us to expand the available deployment area for pumped hydro to all offshore locations between 300m and 2000m of depth, providing an unparalleled storage solution with zero land use and streamlined permitting. Sizable Energy is committed to creating a sustainable and reliable energy storage system that caters to the needs of large floating offshore wind parks and standalone large-scale plants. With a team of dedicated professionals from diverse backgrounds in the energy sector, we are excited to contribute to the transformation of the renewable energy industry.
