Geothermal resources discovered in Kjalarnes, Iceland, set to boost Reykjavik heating supply

Recent discoveries of geothermal hot water in Kjalarnes, Iceland, are promising for the local population. Utilities have identified sources of hot water at Brimnes and Geldinganes, potentially increasing the number of operational geothermal sites servicing the greater Reykjavik area from six to eight in the coming years.

The current hot water supply for the region is sourced from Nesjavellir and Hellisheiði power plants, alongside four low-temperature geothermal areas: Reykjum, Reykjahlíð, Laugarnes, and Elliðárdal. According to a utility executive, these findings are a positive development as they gear up to explore two new low-temperature geothermal systems.

While the discovery of usable water has been confirmed at Brimnes, the utility continues to conduct further research and drilling at both locations to ascertain the full extent of the resources. The hot water produced at Brimnes could potentially meet the needs of an additional neighborhood, accommodating around 10,000 residents.

Officials acknowledge that the need for hot water for home heating and industrial use in the region is on the rise. To manage this demand, they expect to bolster the existing geothermal supply significantly. Systematic evaluations are underway to enhance the efficiency of the current geothermal sites and identify further locations.

As development continues, authorities are optimistic that the new geothermal resources will soon integrate into the district heating infrastructure, with the objective of sustained energy development catering to an increasing population and growing economic needs.
