Iceland Drills Deeper For More Geothermal
Iceland has a $20 million project on the go, drilling into the heart of a volcano to produce 10 times the amount of geothermal power as any previous geothermal project. Most of Iceland's geothermal energy (which powers 90% of Iceland's homes) comes from boreholes between 600 and 1,000m deep. The new project hopes to reach depths of 4000m so that they can get steam at higher pressures and higher temperatures, which produces more power. The estimate is that increasing the steam temperature by 200 deg C and pressure by 200Bar will increase power delivery from 5MW to 50MW for the same steam flow rates.Where Iceland gets its energy from:
