Battery banks, or battery energy storage systems, enable energy produced by renewable sources, like the sun, wind, and water, to be stored and then released when the power is needed most. During low production they release stored energy, ensuring a consistent power supply and a stable grid.

Generated by the natural rise and fall of ocean tides and currents, tidal current energy is global and abundant, making it a valuable untapped source of renewable energy. This energy can be harnessed using either seabed-mounted or floating tidal current turbines. Tidal energy technologies can capture energy from currents in both oceans and rivers.
