Hellisheiði Geothermal Power Station
The Hellisheiði Power Station is the largest geothermal power plant in Iceland and one of the largest of its kind in the world. Located on the Hengill volcanic mass in southwest Iceland, it is operated by ON Power and serves as a vital energy source for the country. The plant harnesses high-pressure steam from geothermal wells to generate electricity and provides hot water for the district heating system of the greater Reykjavík area. It is internationally recognized for hosting the Carbfix project, a groundbreaking carbon capture and storage technology that turns carbon dioxide into stone within basaltic rock formations. The facility includes a professional Geothermal Exhibition where visitors can learn about sustainable energy production and Iceland's unique plate tectonics. Construction began in 2006, and the plant has since been expanded through multiple phases to reach its current capacity. Surrounded by steaming fumaroles and expansive lava fields, Hellisheiði stands as a symbol of Iceland's leadership in renewable energy innovation.
