note that energy from the sea is promising, saying, “the potential estimate for tidal energy was given as 3TW
Ocean energy plant's
equipment space does not require land use, which can be expensive or scarce, and the energy density is higher than air.
In japan,
there is a 100 kW class prototype subsea floating type ocean current power generation system
In japan,
there is a 100 kW class prototype subsea floating type ocean current power generation system “Kairyu.”
The demonstration test
of Kairyu was conducted in the waters off the coast of Kuchinoshima, Toshima, Kagoshima Prefecture.
Deep sea currents can
provide baseline electricity and reduce the need for battery storage that solar and wind require.
