About Iceland and Geothermal Energy

Iceland Geothermal is a collaboration of members of the Iceland Renewable Energy Cluster that work in the geothermal energy space in Iceland and internationally. Icelandic players in the geothermal industry provide a unique set of skills, know-how and experience to help push geothermal development from early exploration, drilling, design and construction of geothermal plants both for power generation and direct use. Iceland’s first geothermal power plant started operation in 1969, followed by two larger plants in 1978 and 1979. With a total installed geothermal power generation capacity of 755 MW, Iceland is among the top 10 countries in the world when it comes to electricity generation from geothermal. In terms of direct use, Iceland has developed into a role model both with its extensive use for district heating (90% of all homes are heated by geothermal energy), but also in the cascaded use of geothermal heat for bathing and swimming, greenhouse operations, fish farming and more. Iceland Geothermal can be of assistance in connecting you with the Icelandic experts related to all stages of development, including support on legislative and regulatory frameworks. Icelandic players have an extensive history of supporting development internationally. Through the Geothermal Training Program of UNESCO (formerly UN University), Iceland has supported the build up of capacity in developing countries around the world contributing to large-scale development, e.g. in Kenya and other regions of this world. We will post a series of overview documents in the coming weeks, below our first with the geothermal power plants of Iceland as of March 2021.

What is geothermal energy?

Geothermal energy is thermal energy generated and stored in the Earth. The geothermal energy of the Earth’s crust originates from the original formation of the planet. Geothermal is location specific i.e. a resource must exist. Access to the resource is gained by drilling and getting access to steam or hot water. Geothermal is a base-load renewable energy resources.

What are the benefits of using geothermal energy?

Renewable

Through proper reservoir management, the rate of energy extraction can be balanced with a reservoir’s natural heat recharge rate.

Small Footprint

Some hydropower facilities can quickly go from zero power to maximum output. Because hydropower plants can generate power to the grid immediately, they provide essential back-up power during major electricity outages or disruptions.

Baseload

Geothermal power plants produce electricity consistently, running 24 hours per day / 7 days per week, regardless of weather conditions.

Clean

Modern closed-loop geothermal power plants emit no greenhouse gasses; life cycle GHG emissions (50 g CO2 eq/kWhe) are four times less than solar PV, and six to 20 times lower than natural gas.

Domestic

Geothermal power plants are compact; using less land per GWh (404 m2) than coal (3642 m2) wind (1335 m2) or solar PV with center station (3237 m2)
