The Cool Down
Summary
A team of scientists in Singapore has made a discovery that could transform the island nation's energy future and potentially set a precedent for other cities around the world.
Two newly drilled geothermal boreholes in northern Singapore revealed unexpectedly high underground temperatures, reaching up to 122 degrees Celsius (252 degrees Fahrenheit) at a depth of just 1.76 kilometers (about 1.1 miles). That's nearly double the previous readings in the region.
A symposium organized by the research team included experts from the International Energy Agency and the European Geothermal Energy Council, with all focused on how cities can harness geothermal energy in dense urban environments.
"The results mean that we have strong potential for electricity generation and district cooling using commercially available technologies in the geothermal energy sector," said Professor Alessandro Romagnoli of NTU.
