Enhanced Geothermal System DeepHeat Begins Operation in Iceland: Accessing Earth's Internal Heat Anywhere

Eavor Technologies announced on January 14, 2029, that its DeepHeat enhanced geothermal system has completed its first commercial power plant construction in northern Iceland and officially began operation. Unlike traditional geothermal plants that rely on natural hot springs and volcanic activity, DeepHeat can work under any geological conditions.

DeepHeat uses a closed-loop design — drilling two parallel wells to 4,000 meters underground, connected by horizontal channels to form a closed circuit. Working fluid (a mixture of water and antifreeze) naturally circulates through the loop: cold water descends one well, gets heated by geothermal energy, then rises through the other well to drive surface generators.

The plant has 50MW installed capacity, capable of powering approximately 35,000 households. Compared to traditional geothermal, DeepHeat doesn't extract groundwater, produces no emissions, and doesn't trigger seismic risks. The plant's capacity factor is expected to exceed 90%, approaching baseload power plant levels.

Eavor Technologies states that DeepHeat's key advantage is geographic universality. 80% of global regions lack traditional geothermal resources, but at 4,000 meters underground, rock temperatures virtually everywhere exceed 120°C. The company has secured project permits in 12 countries worldwide.
