RENEWABLES OFFSHORE & UNDERWATER

Above: Buoyancy Energy Storage, (a) the sketch of the system and the main components, (b) pres- ents the forces exerted in the buoyancy recipi- ent.

Middle Left: World potential of BEST with (a) air and (b) hydrogen as the storage medium. The greater the depth, the higher the BEST potential.

Bottom Right: Proposed operational scenario for

BEST to store offshore wind power near Tokyo,

Japan. (a) wind power, electricity demand and energy losses (GW), (b) energy storage (GWh).
