Direct mixing of geothermal water and condensate into heated groundwater at Nesjavellir power station
The focus of this study is on the Nesjavellir geothermal power station in Iceland, which plays a vital role in supplying hot water for space heating in the capital area. The power station operates as a co-generative single-flash geothermal plant, generating electricity using high-temperature …

Numerical modelling of the shallow reinjection and tracer transport at Nesjavellir Geothermal System, Iceland : an assessment of heat transfer and fluid flow
The Nesjavellir geothermal power plant is the second largest in Iceland, with a district heating capacity of 300 MW and electrical generation of 120 MW. Reinjection of the excess water from the Nesjavellir geothermal plant, derived from separated water from high enthalpy wells and condensed steam, …

The Geochemistry of Silica in Icelandic Geothermal Systems
… values observed at Krafla, Hellisheiði and Nesjavellir. Aqueous speciation calculations revealed that the dominant Si species in all cases were H4SiO4(aq) and HSiO3- at acid to neutral and alkaline pH values, respectively, with NaHSiO3(aq) also being important at elevated Na concentration. …

Geothermal reservoir characterisation using automated mineralogy; implications for CO2 sequestration
… In this study,drill cuttings collected from the Nesjavellir geothermal field in Iceland were analysed using SEM based automated mineralogy to determine any benefits this methodology may provide for drill cutting analysis in geothermal exploration, such as identification of minerals used in …

Weathering and riverine fluxes in pristine and controlled river catchments in Iceland
… of these changes are: the development of the Nesjavellir geothermal power plant in the vicinity, which started producing electricity in 1998; and the construction and operation of the Hellisheidi geothermal power plant since 2006.
