Singapore's Hot New Discovery!

In an exciting breakthrough just 600 meters from Sembawang Hot Spring, researchers in Singapore have hit the highest subsurface temperature ever recorded here—a staggering 122 degrees Celsius! This remarkable find, measured at a depth of 1.76 kilometers, outstrips a previous record of 70 degrees Celsius spotted in Admiralty last year.

A Game-Changer for Energy!

Dr. Jonathan Poh from the Energy Research Institute at Nanyang Technological University calls the discovery a "huge milestone" for Singapore's geothermal exploration efforts. This data could pave the way for geothermal energy to become a viable energy source in a country that currently relies heavily on natural gas for about 95% of its energy production.

Geothermal Energy: A Renewable Goldmine!

Derived from heat trapped below the Earth’s surface, geothermal energy stands as a renewable asset ready to power applications like industrial heating and cooling. The research team, comprising around 15 experts from NTU and TUMCREATE, collaborated with Surbana Jurong to unveil these groundbreaking findings.

Identifying the Hot Spots!

While exploring geothermal potential, the initial plan involved drilling shallow wells across various locations. However, the team discovered that the northern region of Singapore was significantly hotter, recording heat flow that exceeds the global average despite the absence of volcanic activity.

Why Sembawang and Admiralty?

The researchers painstakingly evaluated criteria for suitable drilling sites. They needed locations with good road access and ample open space while keeping a safe distance from both the hot spring and geological faults. Eventually, Sembawang and Admiralty emerged as prime candidates, sitting atop Simpang granite, renowned for its heat-generating properties.

The Future Looks Hot!

Current estimates suggest that temperatures could soar to 230 degrees Celsius at deeper levels of about 5km. This is significantly above the threshold of 150 degrees Celsius required to generate electricity. The team is now investigating advanced heat extraction technologies that can be adapted for Singapore’s unique geological landscape.

A Sustainable Path to Net Zero!

As Singapore aims for net-zero emissions by 2050, geothermal energy offers an enticing solution. Simulations show potential cost reductions of at least 38% for electricity generation and 39% for chilled water production. Embracing geothermal could also shrink greenhouse gas emissions by a staggering 90%.

The Road Ahead!

Encouraged by these findings, the Energy Market Authority is set to launch a geophysical survey to deepen our understanding of what lies beneath Singapore. Anticipated results from this study are expected by the end of 2026.

Engaging the Global Community!

Dr. Poh emphasized the importance of collaboration, as they seek partnerships with other nations to enhance their geothermal endeavors. Professor Alessandro Ramognoli, leading the research team, believes the time is ripe for a pilot demonstration project to explore how geothermal energy can be harnessed effectively.

\"Rather than merely conducting studies, we need to embark on practical demonstrations to understand the real-world applications of geothermal energy,\" he said, signaling a bold new direction for Singapore's energy future.
