The Hellisheiði Power Station (HGPS) is the third-largest geothermal power station in the world. The facility is located in Hengill, southwest Iceland, 11 km (7 mi) from the Nesjavellir Geothermal Power Station. The plant has a capacity of 303 MW of electricity and 133 MWth of hot water for Reykjavik's district heating. HGPS is owned and operated by ON Power, a subsidiary of Reykjavík Energy.
Electricity production with two 45 MW turbines commenced in 2006. In 2007, an additional low pressure steam turbine of 33 MW was added. In 2008, two 45 MW turbines were added with steam from Skarðsmýrarfjall Mountain. The hot water plant was introduced in 2010 and the last two high pressure 45 MW turbines were added in 2011. In order to reduce hydrogen sulphide pollution in the capital area a system was added to the plant in 2014 which reinjects non-condensable gases into the ground.
A pilot direct air capture facility operated by Climeworks is co-located at this site. It was funded by the European Union's Horizon 2020 program, and captures 50 metric tons of carbon dioxide each year. The carbon dioxide is captured, injected into the ground, and mineralized.
