Storengy (STY) is developing a test unit to demonstrate the feasibility of the total geothermal fluid reinjection (including NCG’s) in a single well in high temperature (>150°C) steam dominated reservoir. The demonstration in a high temperature gneissic reservoir initially planned in Castelnuovo in Tuscany (Italy) is going to take place in Hveragerði (Iceland) due to permitting issues. The Castelnuovo site’s characterization and modeling are nevertheless part of the GECO project.
Storengy (STY) is collaborating with the Iceland GeoSurvey (ISOR) to develop the closed-loop test unit and demonstrate it in a 200°C well in Hveragerði, Iceland. To simulate similar reservoir conditions as in Castelnuovo, the geothermal fluid will be supplied with a CO2 tank and steam.
This testing operation will allow for the first ever geothermal system utilised for production/injection flow tests at nearly “zero aeriform emission”.

History of the site
The Castelnuovo pilot concession is aimed at demonstrating the possibility of total reinjection of the geothermal fluid (brine and NCGs) in the same geothermal reservoir. According to Italian laws, these pilot plants must be limited to 5 MWe power
