The Geothermal Power Plant (PLTP) Dieng Unit-1, operational since 2002, extracts mineral-rich geothermal brine, primarily containing silica. Silica is identified as a promising strategic raw material for the automotive, construction, and electronics industries. The UGM team is actively researching the development of nanosilica for applications in fertilizers and community development. Concurrently, Surya University is investigating the potential extraction of silica and lithium from Dieng's brine. Various companies, both domestic and international, have expressed interest in commercializing silica and have submitted proposals. GDE is conducting an internal assessment and resource evaluation to gauge the business potential of silica, with plans underway for the commercial utilization of colloidal silica from both Dieng Unit-1 and Dieng Unit-2.
