From discovery to readiness

NTU's continuing geothermal journey

The initial drilling campaign has ended. The work now shifts from discovering the resource to building the knowledge, partnerships and local capability needed for the next phase of Singapore's geothermal development.

01 · Legacy

Our legacy: a long thread of inquiry

Singapore's geothermal journey began with investigations around Sembawang Hot Spring and has since progressed to deep drilling and direct subsurface evidence.

2002

Early hydrogeological study

Sembawang Hot Spring investigated through shallow drilling and hydrogeological studies.

2021–2025

First deep drilling and exploration

Two deep exploratory slimholes drilled in northern Singapore at Admiralty and Sembawang.

Today

National evaluation continues

Singapore is undertaking further studies to evaluate its geothermal potential, including the Energy Market Authority's call for a feasibility study on the potential deployment of deep geothermal systems.
