Keywords:East African Rift System, hydrothermal system, SATREPS

SATREPS is an acronym standing for Science and Technology Research Partnership for Sustainable Development, and is a joint research program for 3 to 5 years between Japan and developing countries that aims to find solutions to issues of a global scale. Japan Science and Technology Agency (JST) and Japan International Cooperation Agency (JICA) are responsible for the areas of Environment/Energy (Global-scale Environmental Issues, and Low Carbon Society/Energy), Bioresources and Disaster Prevention and Mitigation. The research topic “Comprehensive Solutions for Optimum Development of Geothermal Systems in East Africa Rift Valley” proposed by Kyushu University (Principal Investigator: Yasuhiro Fujimitsu; Research Period: FY2020 to FY2024; Partner Country: Kenya) was adopted in FY2019.

The participants Kyushu University (Faculty of Engineering, Faculty of Science, and Platform of Inter-/Transdisciplinary Energy Research) and West Japan Engineering Consultants, Inc. in Japan and Jomo Kenyatta University of Agriculture and Technology, The University of Nairobi, Kenya Electricity Generating Company and Geothermal Development Company in Kenya. It was scheduled that the project started from FY2020 with a preparation period in FY2019. However, the actual commencement becomes FY2021 caused by a worldwide pandemic of COVID-19. In order to obtain 4 outputs of this research topic (I: Development of high resolution geothermal reservoir models, II: Understanding of silica scale formation mechanism in highly alkaline hot water and examination of countermeasures, III: Proposal of a scenario for enhancement of social acceptance by the expansion of cascade use of geothermal energy, IV: Cultivation of human resources in geothermal development and research capability of the counterpart institutions), we conduct collaborative research of Olkaria and Menengai geothermal areas with the Kenyan institutions.
