Geothermal Exhibition at Hellisheiðarvirkjun

- Museums

The Geothermal Exhibition is situated inside of Iceland’s largest geothermal power plant: the Hellisheiði Geothermal Plant (Hellisheiðarvirkjun), owned and operated by ON Power. This power plant produces electricity for Iceland’s
national grid and hot water for the capital region. When combined with the other geothermal plants in Iceland, geothermal power supplies 30% of all electricity and 90% of all space heating on the island. Geothermal resources
have been intertwined with Iceland’s culture, history, and heritage for over 1000 years and the renewable energy that they provide today is an important part of this continuous timeline. 

Visitors see into an operational power plant and learn all about the geothermal production and distribution of the plant. The exhibition also features information, exhibits, and displays about Iceland’s unique geology, history,
art, and the many exciting innovation projects happening in and around the power plant, including Carbfix, where CO₂ is turned into stone.  

The Geothermal Exhibition is open every day of the year except December 25 and January 1. 

Winter opening hours: November 1 - March 31: 09:00-16:00. 

Summer opening hours: April 1 - October 31: 09:00 - 17:00. 

We invite you to experience our world-leading green power production up close and personal. Feel the engine room humming with energy, learn about geothermal ingenuity, and experience the sights, sounds, and even smells behind the power of Mother Nature.  

The exhibition is interactive and based on multimedia technology, allowing guests to explore and experience among other things: 

  • Visual explanation of the process of geothermal energy production and distribution  
  • The history of geothermal energy in Iceland 
  • A view into our turbine halls 
  • The Carbfix method – we turn CO₂ into stone 
  • Insight into the Geothermal Culture of the island 
  • An Icelandic rocks & minerals collection 
  • Our Curiosity Corner – where visitors of all ages can explore the geothermal process in a fun and colourful way 


Larger parties (10 people or more) and those interested in Carbfix tours are encouraged to send us an email to
– we kindly ask that you include the group size and preferred date and time of the visit.
