Impressive work - We were very impressed with all that we learned about geothermal energy during our visit and even more impressed with Iceland's great success in growing this wonderful asset.

Exhibition Center in the power plant - Download the audio guide using the WR code found at the front desk. Or you can get the ON Geothermal Exhibit app. There is so much info that you will miss if you don’t use the audio guide.

Fascinating and inspiring. - The cold water, hot water and steam valve interactive display really illustrated the entire process for me.

Very informative and easy to digest - I really enjoyed our visit and found it very informative. I understand why it isn’t allowed but it would have been great to go into the turbine hall to get a real sense of the scale. Also an opportunity to visit the carbon capture building would have been really good too.

Worth a Visit - Used some Viator credit so entry only cost £12 instead of £32 which made it more reasonable. Good to understand how it all works and lots of educational information. We were the only people there when we went at 1030.

Interesting Though Rather Technical - Stopped in to visit a working geothermal facility. They offered a 15 minute description of plant operations and the history of geothermal in Iceland. The talk was quite technical so my absorption was limited. Still interesting. There are some good exhibits as well.

Visit a geothermal electricity plant - The Hellisheidi geothermal power plant in Hengill is situated at the foothills of Skarðsmýrarfjall Mountain from where steam from geothermal boreholes drive turbines to generate electricity to supply to all of Reykjavik conurbation and district. The smell of rotten eggs, the release of hydrogen sulphide (H2S), pervaded the air. To reduce the emission of this gas as well that of CO2, both gasses expand 1000x when released from underground, they are pumped back in to the ground from where hot water and steam were extracted. H2S turns to iron pyrites (fools gold) and CO2 turns to calcite (form of chalk) thus sequestering these environmentally harmful gasses. The plant has two floor of exhibition areas which have audio-visual rooms, interactive displays, balconies to see the turbines and an outdoor platform to observe the pipelines. It is one of the world’s ten biggest geothermal power plants. It generates 303MW of electricity and 400MW of thermal energy. The plant is located in a geothermal area which has one of the largest high-temperature geothermal fields in Iceland. Hot fluid is extracted from production wells. Reinjection wells are drilled to pump back the noxious gases. The extracted fluid passes through steam and mist filters. The separated hot steam propels the turbines for electricity generation. The generated power is transmitted to a national grid substation. A carbon capture plant, located adjacent to the Hellisheidi geothermal power plant, captures carbon dioxide (CO₂) directly from the air and mixes it with water then pumps it deep underground for natural mineralisation and permanent storage in the form of rocks.

Infomercial - Paid admission for a public relations infomercial. While classed as a museum there are few artifacts. Mostly video projections of company staff. Example: much is made of the deep well that was drilled. How deep? Good luck finding out. It's mentioned verbally in the video. Bdid they hit their target 450 deg C goal? No idea. Please review what kids will actually learn before loading a bus to here. No experiential displays and what is presented is way abone a 12 years knowledge or interest.
