R&D for Innovative Technologies Applied to Geothermal Exploration and Exploitation

Project overview

Project period: FY2021 to FY2025, FY2022 budget: JPY 1.27 billion

In Japan’s Fifth Strategic Energy Plan, geothermal power is positioned as an energy source that offers the potential to provide low-cost and dependable power. In addition, Japan’s Long-term Energy Demand and Supply Outlook calls for the increased utilization of geothermal power sources by 2030, totaling a maximum capacity of 1.55 million kW and power generation of 11.3 billion kWh.

Furthermore, in Japan’s Green Growth Strategy through Achieving Carbon Neutrality in 2050, supercritical geothermal power generation has been identified as a key technology for achieving carbon neutrality in 2050. This technology is expected to be introduced on a greater scale after 2040 since it would enable both the development of larger capacity power generation facilities, at a level of approximately 100,000 kW, and the reduction of power generation costs.

This project ultimately aims to promote greater utilization of geothermal power generation, including the development of geothermal resources found in Japanese national parks, as one of Japan’s primary sources of renewable power, and realize a maximum geothermal power generation capacity of 1.55 million kW by 2030. To promote greater utilization of geothermal power, NEDO will carry out R&D activities under this project related to surveys targeting resources for supercritical geothermal power generation, which is attracting attention as an innovative next-generation technology.

R&D activities are taking place in the following areas:

  1. Development of supercritical geothermal resource technologies
  2. Development of environmental conservation technologies
  3. Development of technologies to promote greater utilization of geothermal power generation
