Geothermal Energy Discovered on Grímsey Island

Experimental drilling has revealed that there is heat in the ground on Grímsey, Iceland’s northernmost inhabited island, which may be used to harness geothermal energy. Until now, islanders have used diesel oil for electricity and heating.

“It looks promising. The hole has become 460-meters deep and the heat at the bottom is 65 degrees [149°F],” Fridfinnur Daníelsson, an engineer at Alvarr in Grímsey, who is responsible for the experimental drilling, told Fréttabladid.

“I think the drill has cut a 55-degree vein at a depth of 400 meters, but it is difficult to estimate. We plan to drill much deeper,” Daníelsson said, adding that he doubts enough warm water has been found yet.

Daníelsson hopes that he can finish his research before next weekend and drill down to a depth of 600 meters. “Then we will know for sure. The temperature increases relatively fast down below a depth of 400 meters. So I can only be hopeful.”
