What is BEST energy storage technology?

BEST (Buoyancy Energy Storage Technology) is an energy storage solution that uses an electric motor/generator. It stores energy by lowering a compressed gas recipient in deep sea floors and generates electricity by allowing it to rise through the water, as shown in Fig. 1.

What is a buoyancy energy storage system?

A buoyancy energy storage system is a system that stores energy in weekly cycles in synchrony with a battery system storing energy in daily cycles, or to compress hydrogen in an efficient way. The design of the buoyancy storage recipient must consider the high underwater pressures.

Is there an underwater gravity energy storage system?

Why are islands suitable for BEST systems?

Islands usually have a short continental plate, which allows a BEST system to be installed a few kilometres from the island. This makes them suitable for Buoyancy Energy Storage Technology (BEST) systems. However, some coastal areas have long continental plates, which would increase the cost of the project due to the increase in underwater transmission costs.
