SINGAPORE – A nationwide study will be conducted to assess how Singapore can harness geothermal energy for power generation, as well as identify suitable locations for building geothermal power plants, said the Energy Market Authority on Monday.
The proposed regions to be surveyed in this study would potentially include mainland Singapore , territorial waters and offshore islands. The country is exploring localised energy options – aside from solar – that would help it diversify and decarbonise its energy resources, in order to hitTherefore, a holistic study is required to determine the overall geothermal potential and scalability of geothermal power across Singapore, added EMA.
Conventional geothermal systems harness hot water and steam to generate electricity, which is not possible in Singapore due to the lack of viable resources at shallow depths. Prof Romagnoli told ST that this is an attractive idea, but drilling at 10km depth could pose substantial challenges on top of the difficulty involved in extracting heat from the rock.
Prof Romagnoli said that a nationwide study could be useful in identifying sites for deep drilling and designing drilling wells, as well as managing project risks.
