Bipolar submarine cables (total transmission capacity: 600 MW) are installed across the Tsugaru Strait between Hokkaido and Honshu islands in Japan. To make electricity supply more reliable in Hokkaido, Hokkaido Electric Power Co., Inc. has additionally planned the installation of a 300 MW interconnector, which is the Hokuto-Imabetsu DC Trunk Power Line connecting Hokuto Converter Station in Hokkaido with Imabetsu Converter Station in Honshu.
Since communications networks have come into widespread use, various things are connected to networks in the form of cloud computing, including automobiles and industrial equipment, as well as smartphones. This is the development of the Internet of Things (IoT). The IoT produces big data. New services emerging from the use of big data are expected to improve the quality of our life and productivity. In the era of big data, high-capacity and high-reliability networks are increasingly important as infrastructure.
The issue of water contamination is a challenge currently facing the international community. The Sustainable Development Goals (SDGs) published by the United Nations refer to the issue of water quality, setting a goal of reducing emissions of untreated water by half by 2030. Specifically, in economically fast growing nations, rivers polluted with industrial and domestic wastewater have adverse effects on human health and the ecological system, due to industrialization and urban population concentration.
