| Abstract | In 2010 a cooperation project between Germany and Indonesia has been initiated in the field of geothermal energy development: Sustainability concepts for exploitation of geothermal reservoirs in Indonesia – capacity building and methodologies for site deployment. Within this project several research activities have been carried out which were closely accompanied by capacity building measures, such as a PhD-program in Germany with focus on Indonesian topics. Research activities and knowledge transfer were carried out bidirectional in order to strengthen science and technology for both, Indonesian and German partners. In the field of exploration, low enthalpy geothermal green fields in magmatic (East Java) and amagmatic settings (North Sumatra) have been investigated. Also analyses on the controlling mechanisms of operated geothermal fields in North Sulawesi and West Java have been carried out. Regarding sustainable exploitation, we report on the integrated geoscientific monitoring networks that were established and on solutions developed for on-line fluid-chemical monitoring in operating geothermal plants. In the field of plant technology, the technical concept for a demonstration binary power plant as bottoming unit at an existing site has been elaborated. In this paper, we are reporting on the objectives, status, progress and achievements of the scientific investigations. We will show that the project findings can be applied to other locations in Indonesia and that they can be used for further developments. Networking with and involvement of additional international partners in ongoing research tasks beyond this project has already been started. The realization of the demonstration binary power plant will be carried out in another collaboration project which could be the basis for a more widespread deployment of binary power plants and for a decentralized use of geothermal energy in Indonesia. |
