Challenge to develop new energy technology – Superconductive DC Power Transmission –
Global economic development is leading to increased power consumption, depletion of fossil fuel resources and air pollution. Using high-temperature superconducting cables with zero electrical resistance, the Center of Applied Superconductivity and Sustainable Energy Research (Dr. Satarou YAMAGUCHI) is developing direct current transmission technology that will reduce power loss (from the power station to the point of consumption) to less than one-tenth of the current level. Zero electrical resistance eliminates the need for high-voltage transmission, significantly reducing the number of substations needed, and thus lowering the cost of the power grid. The project has attracted attention from foreign countries looking to resolve energy issues, and a memorandum of understanding (MOU) for joint development with Russia’s national power transmission company has already been signed.
