Japan relies mostly on fossil fuels for its domestic consumption after the Hiroshima crisis, but things are changing now as a long running test project is bearing fruit.
Japanese engineers had been trying to build a machine that could harness the energy of ocean currents, and they have succeeded. Engineers have built a giant sea turbine called Kairyu that looks like a 330-ton airplane, it floats at the depth of 30-50 meters while being anchored to the seabed. IHI corporation, the company that has spearheaded the project, is aiming to harness the power of one of the world’s strongest ocean currents (the Kuroshio Current). Japan’s New Energy and Industrial Technology Development Organization (NEDO) hopes to produce around 200GW of power annually, which is 66% of Japan’s domestic consumption.
Japan has an advantage in terms of oceanic currents but is an unfavorable place for establishing traditional renewable energy systems like wind. Japan has already invested in wind and solar extensively after it did away with nuclear power post the Fukushima disaster.
