Further promotion of geothermal development

Geothermal energy is a clean and renewable energy source that emits almost no CO2 during power generation. It is a base load power source that can generate power in a stable manner regardless of natural conditions such as the weather. We will steadily proceed with projects under investigation, exploration, and development, while accelerating the efforts and technological development for starting new projects to achieve carbon neutrality by 2050.

Promoting domestic development of geothermal resources

Plan: 
We will strengthen efforts to promote geothermal development in natural parks where development has not been advanced despite the existence of geothermal potential. Specifically, we accelerate the identification of potential geothermal projects in natural parks through focusing surveys on domestic geothermal potential. Based on the results of this activities, we lead project creation by Japanese companies. In the surveys, we acquire and analyze data on subsurface geology and temperature structure, to assess geothermal prospectivity in promising domestic areas.

Current status:
Geothermal resource potential studies are being conducted.

Promoting support for reducing financial risk

Plan:
When applying the conditions of financial support of subsidy for high-risk initial surveys (geological, geophysical, and well-drilling surveys to confirm promising geothermal resources), equity capital for exploration projects, and liability guarantees for development projects, we will be flexible by reconsidering subsidy rates and examining standards of equity capital and liability guarantees. This will encourage and strengthen support for accelerating surveys in natural parks and geothermal developments.

Current status:
Subsidy program and support services for equity capital and liability guarantees are being conducted.

Expanding the potential for geothermal development

Plan:
We will strengthen the development of geothermal reservoir exploration, drilling, and evaluation/management technologies to shorten the development period and reduce costs of geothermal development undertaken by Japanese companies. We will also steadily conduct evaluation for the practical use of the Enhanced Geothermal Systems (EGS).

Current status:
Technical development of the artificial recharge, carbon recycled CO2 geothermal generation, and evaluation of feasibility and techno-economic performance of the available Closed-Loop Geothermal System for electricity generation are being conducted.

Strengthening geothermal resource surveys overseas

Plan:
We will work to improve geothermal survey technologies and promote the development of domestic geothermal resources by providing accumulated knowledge from surveys in volcanic belts overseas (that are similar to Japan) to Japanese companies.

Current status:
Overseas geothermal resource surveys are being conducted.
