Loading ...We have a geothermal electric plant here just five miles from my home. It is located in the East Rift zone of Kilauea, very near where the 2018 eruption occured. The geothermal wells drill down into trapped lava in the rift crack. The danger is all the H2S gas also trapped in these rock bubbles. But they have high pressure containment technology on the wells, thanks to old oil well blowout technology, and none have ever leaked. They circulate the hot H2S and pump it back into the well. Thermal transfer to pentane, and again to water to run steam turbines. This geothermal plant supplies 20-25% of electricity to our island of approx. 200,000 population.
