TOKYO -- Japan marine transport company Mitsui O.S.K. Lines aims to launch a large-scale facility that uses ocean thermal energy conversion technology to generate power by around 2025, Nikkei has learned.

This technology generates power by harnessing the difference in temperatures at the surface of the sea and in deep water. It is estimated that construction of the 1,000 kilowatt power station will cost several billion yen.
