The paper by Darma et al. (2010) focuses, as in the past on the development of electricity generation by geothermal energy, however five years ago a group of researchers in government sponsored research and technology agency (BPPT) began to investigate methods to apply geothermal energy to the agriculture sector, particularly to sterilize the growing medium used in mushroom cultivation.
The process is still at the research stage not having yet become commercial.
Other uses of geothermal fluids include palm sugar processing, copra drying, tea drying and pasteurization and some fish farming. These activities are spread over about six areas totaling about 200 – 300 tonnes/hr of fluid.
No heat pump installations are used to date as they appear to be uneconomical at this time due to the availability and abundance of high enthalpy fluids.
Lund and Freeston (2001) cited 2.3MWt and 42.6TJ/yr as the usage for bathing and swimming and are assumed to remain unchanged. A paper by Surana et al. (2010) indicates additional direct use installations in the country, including bathing and swimming, Mushroom growing, palm sugar production, copra and cocoa drying, aquaculture, and space heating. Unfortunately, no data on capacity and annual energy us were provided, and thus cannot be estimated for this report.
