The Nesjavellir geothermal field is a high-enthalpy geothermal system within the Hengill area of SW-Iceland. Construction of the geothermal power plant began in 1987 and the first stage of the thermal plant was commissioned in 1990, following an intensive drilling and testing phase in the 1980s. The last 30 MWe turbine generator unit was commissioned in 2005. Mannvit Engineering of Iceland played a leading role in the design & development of the Nesjavellir Geothermal Power Plant, a combined heat and power plant.

Your plant is a wonderful thing – Here in Nevada, USA, we also have significant geothermal resources, but they are too cool to make steam. Our plants use a binary cycle with a low boiling point liquid like isobutane to drive the turbines. All the water is injected back into the earth after heat exchange. I’m a bit worried about all the steam discharge in your video – that’s water not going back to be re-heated and also it probably contains some H2S. In any case, good luck, and good job!
I wish more places would look into geothermal power, I would think it would be a very good source of power.
