Hellisheidi Geothermal power plant- Iceland, Technology
The Hellisheidi Geothermal Power Plant in Iceland is a state-of-the-art facility that uses advanced technology to generate electricity and heat from geothermal resources.
Some of the key technologies used in the power plant include:
Geothermal Wells: The power plant has over 30 geothermal wells that are drilled into the ground to extract hot water and steam from the volcanic field. The geothermal wells are up to 2.5 km deep, and the temperature of the water and steam can be as high as 300 degrees Celsius.
Steam Turbines: The steam extracted from the geothermal wells is used to power turbines, which generate electricity. The Hellisheidi Geothermal Power Plant has five steam turbines, each with a capacity of 60 MW, for a total capacity of 303 MW.
Binary Cycle Technology: The power plant uses binary cycle technology to generate electricity from low-temperature geothermal resources. This technology involves using a secondary fluid, such as isobutane or pentane, to generate steam, which then drives a turbine to generate electricity.
Carbon Capture and Storage: The power plant has a carbon capture and storage system that captures up to 85% of the carbon dioxide emissions from the geothermal fluid. The carbon dioxide is then injected into underground basalt formations, where it reacts with minerals to form stable carbonates.
District Heating: The hot water extracted from the geothermal wells is also used to heat homes and buildings in Reykjavik through a district heating system. The water is piped to the city, where it is used to heat water and air for heating purposes.
The Hellisheidi Geothermal Power Plant is a showcase of modern geothermal technology, demonstrating how geothermal resources can be harnessed to provide clean and renewable energy.
Hellisheidi Geothermal power plant- Iceland, Environment Impact
