Wedoany.com Report on Feb 3rd, The Institute of Geological and Nuclear Sciences (GNS Science) of New Zealand (ESNZ) recently signed an international cooperation agreement with several Japanese institutions to jointly carry out a research project on the connectivity between shallow and deep geothermal reservoirs. The Japanese side is led by Kyushu University, with participation from Mitsubishi Gas Chemical Company and the National Institute of Advanced Industrial Science and Technology.

The project will employ geophysical and geochemical methods to assess the connectivity characteristics between hot spring aquifers and deep geothermal resources. This research is of significant importance for the development of geothermal power generation in Japan, as it needs to balance the demands of the hot spring-related industry and environmental protection. Currently, geothermal power generation in Japan accounts for approximately 0.3% of the nation's total electricity generation.

In contrast, New Zealand's utilization of geothermal resources is more mature, with geothermal power generation accounting for 15% to 20% of its electricity mix. The country has conducted large-scale exploration in the Taupo Volcanic Zone and established a zoning management system, dividing geothermal areas into different development grades to achieve a balance between resource utilization and environmental protection.

The goal of this international collaborative research is to apply the findings to the development and utilization of Japan's geothermal resources, including expansion in the power generation sector. By drawing on New Zealand's experience and technology, it is expected to improve the development efficiency of Japan's geothermal energy.

This research reflects the trend of international cooperation in the field of geothermal energy, and the related findings may provide new technological pathways for geothermal resource development.
